Asus P8Z77-V Pro
The $220 price point represents the top of the mid-market for enthusiasts and is justified by the special features found on the Asus P8Z77-V Pro. A PCIe module on the I/O panel adds WiFi connection and complements Gigabit Ethernet, two additional USB 3.0 controllers provide four additional ports to those controlled by the chipset, another SATA 6 Gb/s controller supports two additional drive, a sixteen-phase (12+4) CPU voltage controller guarantees stability during overclocking, the CLR_CMOS button on the I/O panel will help overclockers restore initial settings and an optional BIOS will allow you to start over when the reset doesn't work.
Asus makes a brilliant move and leaves USB 2.0 ports on the rear panel for connecting a keyboard and mouse. Four more headers add eight front-panel ports, in addition to two front-panel USB 3.0 connectors.
Asus-exclusive features like MemOK, TPU, EPU and USB BIOS Flashback are also present. The MemOK feature temporarily lowers the memory clock to allow access to manual settings in UEFI, and has been useful in the past for booting poorly programmed models. The TPU feature automatically overclocks the system to Asus' specified levels, while the EPU automatically underclocks the CPU core voltage for additional power savings. USB BIOS Flashback allows firmware to be updated from a flash drive installed in a special port, but we also found that the feature allows the system to boot with different profiles.
The board has three PCIe x16 slots, although only two of them operate at PCIe 3.0 speeds via the onboard controller. The second slot takes eight lanes from the first when a card is installed in it, and the third slot uses four lanes of the PCIe 2.0 controller on the chipset. Asus knows that most enthusiasts computer games will consider the board for a dual graphics configuration, and positions the main PCIe slots with a large gap for maximum cooling.
The company did not skimp and placed six four-pin fan connectors on the board, each supporting improved control technology. We already wanted to classify the P8Z77-V Pro model as a high-end product, but we noticed the absence of some functions. For example, there is no diagnostic panel on the board, although there are LED indicators next to various devices showing that they are working. Testers will probably be disappointed by the lack of power and reset buttons on the board, although they are not important if the board is installed in a case. We also did not find a voltage control point, which makes it impossible to connect measuring instruments. Asus seems to prefer that we rely on software readings. There is also no FireWire controller, although most users no longer use it. One of the additional internal USB 3.0 connectors will be covered by a third video card, but it is unlikely that enthusiasts will install a fast card in the second-generation four-channel slot.
Apparently, cost-cutting measures may relegate a high-end motherboard (for all other functions) to the realm of mid-budget PCs, but almost any motherboard over $200 includes eSATA support. Asus has not forgotten about this and added a plug with eSATA/USB 3.0 connectors for the rear panel to the kit. We will leave our opinion on this for the conclusion of this article.
The 802.11n Wi-Fi adapter is installed between USB 2.0 and the display connectors on the rear I/O panel, and the antenna is connected there too. The kit also includes four SATA cables, external antenna Wi-Fi and dual SLI bridge.
Firmware Asus P8Z77-V Pro
The P8Z77-V Pro overclocks our processor to 4.77 GHz at 1.30 V with a base frequency of 101.4 MHz times 47. Instead of using the manual settings defined by Asus, we started overclocking A.I.Tuner in X.M.P mode.
Memory is defined in DDR3-2703 mode, and when a lower CPU multiplier is used, the P8Z77-V Pro board can boost G.Skill DDR3-2666 memory to stable DDR3-2715 levels.
If the values are shown in red (as Core Voltage 1.30 V and System Agent Voltage 1.20 V in our case) this means that they are higher than recommended for , although some of our engineer friends advise the opposite. We asked a lot of questions before choosing these settings, but only time will tell the competence of these tips.
The DRAM Timing Control submenu allows you to configure primary, secondary and tertiary timings.
The CPU Power Management menu provides multiplier control for fixed mode, along with some current limits. Asus claims that the Automatic power setting is sufficient for most users, barring aggressive overclockers, and we never experienced power failure or lockup when using it.
Probably the most important parameter in the Digi+ Power Control submenu is Load-line calibration. We were pleasantly surprised to find that the Auto setting kept the CPU core stable under varying loads.

In 2012, ASUS released several motherboards based on the Z77 Express chipset, which were designed to cover the entire market segment from low budget to high budget. As is usually the case, the budget class had rather meager capabilities for overclocking processors, which could not be said about more expensive options, but they cost an order of magnitude more.
The golden mean was the Asus P8Z77 VPro (V Pro) motherboard, which not only had good characteristics, but also good overclocking functions. Why, after so many years, does the question of motherboards become relevant again? Because not everyone who wants to build their own computer, especially a gaming one, has the budget for new and modern equipment. can be easily found at flea markets at quite affordable prices, but their basic characteristics today may not be enough, so they need overclocking. But to perform that same overclocking, you need a good motherboard.
The VPRO motherboard is a great value for money today. Of course, you can't find a new one anywhere. turn out to be, but on the secondary market - no problem, although there are not many of them there. However, it’s worth understanding everything in order.
Description
Before we start our review of VPro, it’s worth saying a few words about the board itself.
Socket, The Asus P8Z77 VPro board works with is LGA1155. This means that the board works with all processors of the Sandy Bridge and Ivy Bridge family. Due to good overclocking capabilities, the most advantageous options for this model will be core i-7 2600K, 2700K and 3770 TO. Among the core i-5 family, the legendary 2500K, 2550K and 3570 are perfect TO. Certainly However, other models of these two families can also be overclocked, but the previously listed ones are a priority.
Another important innovation in VPro is the ability to control the rotation speed of coolers (fans) through a separate menu in the BIOS system.
The changes also affected USB systems 3. 0. In particular, the data transfer speed when using these connectors has increased by as much as 170%. This was achieved thanks to implementation support for the UASP protocol, for which we should thank the company’s engineers.
It is also worth mentioning the support of the Asus P8Z77 VPro Thunderbolt interface. This model was one of the first in the company’s ranks to come out with a new connector. More details about it will be in a special section.
And, of course, ASUS proprietary developments have not gone away, such as TPU, MEM Ok, All Suite II and more. We will try to talk about all this in the review.
Review
I would like to start our review of the Asus P8Z77 VPro motherboard by considering its appearance, as well as various elements.
The motherboard textolite is painted in a dark color, which undoubtedly gives the board a more strict and " serious" look. Thanks to the standard format (ATX) and dimensions, all elements and connectors are located in their usual places, and not as is the case with mini-ATX. The connector for the central processor here, as mentioned earlier, is LGA1155, and it supports work with both the Sandy Bridge and Ivy Bridge generations, and from " boxes", without the need to additionally flash the BIOS.
Next to the processor socket there are 4 slots for brackets random access memory DDR3. There is support for dual-channel mode. To do this, identical memory modules should be placed in connectors of the same color. The maximum amount of RAM that the board can install is 32 GB. As for the memory frequency, as indicated on the manufacturer’s official website, the motherboard supports modules with a frequency of 2400 MHz.
By the way, a little about the processor cooling system. If you plan to overclock, you will need a pretty good cooler, more likely, tower type. If it is too large, it may well happen that it will block the nearest RAM slot. If the modules have additional cooling, then the second connector may also be inaccessible. This is worth considering.
Below the processor socket there are several expansion slots, painted in different colors. The two smallest are PCI 2.0 x1. Between them are PCI-E 3.0 X16 (top) and PCI-E 3.0 X8. There are also 2 regular PCI slots. Well, everything is closed by 1 slot of PCI-E 2.0 X4 format. The layout is quite good, there is a margin for distance, so you can safely install 2 large gaming video cards on the board.
As for the operation of the slots itself, it is implemented here as follows. If there is only one video card on the motherboard, then it will work in 16x/0 mode. Well, if 2 cards are inserted, then the work will take place in 8x/8x mode. It is also important to remember that to ensure the operation of one video card in 16x mode, it must be inserted into the first PCI slot, i.e., which is colored dark blue.
In addition to all this, on the Asus P8Z77 VPro motherboard you can find several controllers from a third-party manufacturer ASmedia, which are responsible for the operation of the PCI slots. This fact can easily be considered a plus, since, unlike other controller manufacturers, ASmedia has no problems with the compatibility of some older PCI boards.
At the bottom right of the motherboard there is a cooling radiator to remove heat from the chipset, 8 SATA ports and ASUS proprietary switches for TPU and EPU modes. You can also find a small green LED next to them. It is needed so that in the event of any malfunction, the cause can be determined by the light signal given. By the way, there are 2 more such LEDs on the board - one near the processor, and the other next to the memory slots.
If we talk about SATA ports, they, like PCI slots, are painted in different colors. 4 blue and 2 white ports are based on Z77 Express. The former provide data transfer speeds of up to 3 Gbit/sec, the latter - 6 Gbit/sec. Two more ports are controlled by a separate controller from the same ASMedia. The data transfer rate is 6 Gbps.
In addition, the motherboard has 8 USB generation 3.0 ports. Four of them are traditionally controlled by the 77th chipset from Intel. The operation of the other four is provided by another controller from ASMedia - ASM 1042.
Interesting fact: SATA ports and USB connectors that are controlled by ASMedia controllers may be inactive. This is directly related to which PCI slots are used on the this moment.
It is definitely worth mentioning the branded " feature " ASUS - USB BIOS Flashback. This technology not only allows you to safely update the BIOS firmware, but also protects it from possible problems. I would especially like to highlight additional reinsurance in case something goes wrong - the BIOS chip can be safely removed from its connector, and when the problems are resolved, insert it back into place.
The well-known Realtek codec is responsible for the sound on the Asus P8Z77 VPro motherboard, which provides support for eight-channel sound. Nothing remarkable.
The network module also does not stand out as anything special - it is Intel WG82579 V.
The rear panel of the Asus P8Z77 VPro has many outputs and connectors. Here is their list:
- Combined PS/2 connector for connecting a mouse/keyboard.
- 2 USB 3.0 ports (next to P/S2).
- 2 USB 2.0 ports (located below and black).
- Thunderbolt connector, HDMI and SPDIF optical audio output.
- Next comes the classic VGA connector and one DVI.
- Below them are 2 more USB 3.0 ports and an RJ-45 connector.
- The usual audio unit with six inputs completes everything.
Well, in conclusion, it’s worth talking a little about the cooling system of the board itself. If you look, you can find 3 radiators:
- On power circuits.
- On the built-in graphics chip.
- On the chipset.
The largest heatsink is installed on the power circuits (power elements) of the CPU Vcore processor. It is immediately clear that the engineers approached the matter responsibly, since the power elements are one of the most important places on the board, and in no case should strong heating, and even more so overheating, be allowed. As for the fastening, it is reliable. The radiator is secured using a pressure plate. A special gasket of approximately medium thickness is used as a thermal conductor.
The built-in graphics core has a much smaller heatsink, which is logical in principle, because the heat dissipation from the IGPU is not too strong. The thermal interface is used the same, and the fastening is implemented through a pressure plate. Everything is exactly the same as with the first radiator.
Well, the last heat sink element is located on the Z77 Express chipset itself. At first sight It may seem that the radiator is quite impressive in size, but it is not. Here you can clearly see the desire of the developers to install something more beautiful in terms of design than efficient in terms of heat dissipation. The only good thing is that the 77th chipset itself does not get very hot, so this heatsink will cope with its task.
As for the thermal pad, it is an ordinary paste, only very thick and viscous. The fastening, as in previous cases, does not cause any complaints.
If we talk about heating, then all the heat-dissipating elements cope with their task without any problems. On the radiator of the power circuits, the temperature under maximum load did not exceed 76 degrees. On the graphics chip - 50, and on the chipset even 37. And although the indicator of 76 degrees on power batteries is quite high, this can still be considered an acceptable result. But if we raise the question of more efficient cooling, then it is best to use a low-profile cooler with a 120 mm fan, rather than a tower type. Thus, the air flow will not only cool CPU, but also heatsinks for power supply circuits and the built-in graphics core.
Important! Since the Asus P8Z77 VPro motherboard can currently only be purchased at flea markets, it is worth checking the condition immediately after purchase thermal interfaces and be sure to change the thermal paste on the chipset heatsink.

Main functions
Now, after reviewing the technical characteristics of the Asus P8Z77 VPro, we can move on to the main functions and features of the board. They will be discussed below.
FAN Xpert 2
Fan rotation speed control. Thanks to FAN Xpert2 technology, the user can independently adjust the rotation speed of coolers at different temperatures through the BIOS. The most important thing is that the connected fans have a 4-pin connector, not 3. This is important because such models have a PWM controller, which is responsible for the rotation speed. By the way, the Asus P8Z77 VPro motherboard has as many as 6 4pin connectors.
So, after entering the BIOS menu, just go to the Monitor tab, where, in fact, the processor temperature is displayed, motherboard, the number of connected fans and their rotation speed. Changing parameters is easy, just scroll down the menu a little. In addition to manual settings, there are several presets, including an automatic mode. In general, there is no point in going into details, everything is quite clear.
MEM OK for memory
MEM OK. Asus P8Z77 VPro acquired this function for a reason. It often happens that a user wants to slightly “upgrade” his system in terms of RAM capacity and buys several new sticks of larger capacity. But what a surprise it is when a completely new memory stick is not detected by the system! There can be different reasons, and the most common of them is incompatible memory and motherboard frequencies. So, the MEM OK function allows you to automatically reduce the frequency of the RAM of the new stick to the most suitable one, for example, 1333 MHz, and by this " make it work.
To use this function, just press one small button, which is located next to the memory slots. There is also a signal LED that reports errors.
Thunderbolt
Another of the main features of the motherboard is the presence of a Thunderbolt interface. Asus P8Z77 VPro was one of the first boards from the company to feature this interface. His main feature is that it allows you to transfer information twice as fast as regular USB 3.0 and 20 times faster standard USB 2. 0. The maximum throughput of the new interface can reach 10 Gbit per second, which is simply amazing. In addition, if you have the appropriate adapter, you can also connect an external monitor to the Thunderbolt connector that has one of the connectors: DVI, HDMI, VGA, D-sub, etc.
BIOS
BIOS Asus P8Z77 VPro deserves a separate section. First of all, I would like to note the ease of use of the UEFI system (BIOS shell). Navigation is fast and there is mouse cursor support. You can select the interface language. It is also very convenient to overclock and monitor all temperature information in real time.
Generally , BIOS Asus The P8Z77 VPro is completely identical to more advanced models, for example, ASUS Sabertooth, which also runs on the Z77 socket.
It is also worth mentioning the Asus P8Z77 VPro BIOS update, which was released in September 2013. It includes important fixes and improvements that improve system stability, especially when overclocking.
Tests
Before we start testing, it’s worth talking about the configuration. Since the Asus P8Z77 VPro runs on LGA1155 (socket), the processor was installed on it with an Intel core i-7 2600K. RAM - 2 sticks of 2 GB 1600 MHz, video card - GTX 580 1.5 GB. The configuration is generally simple, but quite suitable for testing.
CPU overclocking
Since the board is predisposed to overclocking, it is worth checking its capabilities. The multiplier is set to 48, the voltage is 1.472V, and the bus frequency is increased to 100.7 MHz- this is the most successful option that was achieved. When the frequency increases to 102-105 MHz The computer starts and works, but when passing the test in the Prime program, there is a freeze, and in the very first minutes. There is no point in increasing the frequency even more, but lowering it, on the contrary, has borne fruit. Thus, the frequency of the i7 2600K processor was raised to 4834 MHz.
Overclocking RAM
There were also no problems when overclocking the memory. The optimal option, in which everything works well, is to set the memory multiplier at x21.3. With this multiplier, the frequency increased from the standard 1600 MHz up to 2235 MHz, which cannot but rejoice.
Performance
Well, in conclusion, I would like to summarize the results of the performance test in some applications:
- CINEBENCH - 29720 points.
- LinX - 131.6674.
- Photoshop - working with filters on photo, with resolution 12000 to 9000 - 65 sec.
- WinRAR - 5245 points.
- 7-Zip - 21285 points.
In general, the results are very good and are in no way inferior to more expensive boards (if the same configuration is installed on them).
Problems
Often on forums or thematic communities you can come across the question of why the Asus P8Z77 VPro does not " starts." In fact, there is no need to be afraid, because there is nothing wrong with this. In most cases, the problem is caused by RAM, which is not entirely compatible with motherboard. To solve the problem, you just need to click on the MEM OK button located next to the memory slots.
If this does not help, then perhaps you should try resetting the BIOS settings first, and then flashing it. This is done quickly, and taking into account the support of proprietary USB BIOS Flashback technology, it is also easy. Just put it on a flash drive latest version firmware for BIOS, plug it into any of the USB ports, and then press and hold the corresponding button on the motherboard for 5 seconds. It is located among the PCI slots. In most cases, these manipulations help solve the problem.
Drivers
Another important point associated with this motherboard are drivers for Asus P8Z77 VPro. In most cases, many owners of advertisements for the sale of motherboards no longer have any kits that came with with board with from the very beginning. This means that most likely no driver disks have been preserved, so the future buyer will have to look for them on the Internet on their own. The best way to do this is on the manufacturer's official website.
Prices
Here he comes turn of one of the most interesting questions - prices. Today, the cost of the P8Z77 V Pro board at flea markets is approximately 5 to 8 thousand rubles. The spread is not small, but the problem is not even that, but the fact that it is extremely difficult to find a board separately without a processor. Although, on the other hand, if you plan to purchase a kit " mother+percent", then such a purchase will be even more profitable. The only thing is that you definitely need to check everything for functionality.
The situation when a new processor also requires a new motherboard with a new chipset has already occurred quite often. All motherboard manufacturers were rushing to introduce their new products, playing the chicken and egg game. However, as you already know, this spring everything is going differently - new Intel processors codenamed Ivy Bridge can be used on “old” boards. But this does not mean at all that the leaders of the components market need not worry - users who want everything new are the most active and very interested in financial terms, so everyone greeted the release of the seventh series chipset line with enthusiasm.
ASUS now has a dozen products in its arsenal based on the maximum version of the chipset line - Intel Z77. Honestly, in our opinion, this is overkill: it will not be easy for users to understand the differences and numerous suffixes if we are talking about ordinary “workhorses”. In this article we will look at the P8Z77-V Pro motherboard.
Among its distinctive aspects, the manufacturer mentions the use of the Digi+ chip to control power circuits, the ability to use four-chip SLI and CrossFireX, and the fan control system in the Fan Xpert 2 case.
Equipment and proprietary utilities
Traditionally, out of a dozen models on one chipset, only a few received original packaging. Our hero today was unlucky - an ordinary medium-sized cardboard box. Its design, at first glance, is almost no different from many other mass-produced devices. But upon closer examination, you can notice the texture (embossment) on the cardboard.
Noteworthy detailed description numerous features of the board. It's a pity that it's only in English. And these are not just rewritten in beautiful words specifications, but truly unique functions of the device. We will look at some of them in more detail below.
The scope of supply for this model is quite rich: a plug for the rear panel of the board with a black insert and connector labels, two SATA 6 Gb/s cables with latches (one straight connector, the other angled), two “just” SATA cables with the same connectors, flexible SLI bridge, special adapters for easy connection of connectors on the front panel of the case to connectors on the board (one for buttons and indicators, the second for USB ports), a bracket for the rear panel of the case with a pair of USB 2.0 ports and one eSATA, proprietary wireless Wi-Fi module Fi with external antenna, thick user manual (on English language), DVD with drivers, programs and documents.
The motherboard comes with many utilities, some of which deserve special consideration in a separate article, and we will try to return to this issue in the near future. All of them are collected in a single AI Suite II shell to simplify both installation and work with them.
From the manufacturer's website you can download an updated version of the kit in the form of a single archive. The kit includes utilities for monitoring the system status, collecting system information, updating software and BIOS, managing the Wi-Fi controller (including organizing an access point), setting up USB ports, selecting power saving modes, setting up power management, overclocking the system, installing prioritizing network traffic, remote control from wireless mobile devices.
The TurboV utility is used to automatically overclock the system. We checked its performance in automatic mode with processor Intel Core i5-2500K and Corsair H100 liquid cooling system. Selecting the “Fast” profile made it possible to increase the processor frequency by a third in just a couple of seconds - to 4.3 GHz.
A longer process in the “Extreme” profile showed even more impressive results - the frequency exceeded 5.2 GHz. However, it should be noted that the second option turned out to be unstable under the load of the LinX program. In the “beautiful” 5 GHz mode (100 MHz × 50), the system coped with this test. We also mention the presence of an automatic reset system in case of unsuccessful overclocking
Features of the board
The motherboard uses black PCB, which allows it to look both strict and stylish. It has a standard ATX size (304x244 mm), so all configuration elements could fit freely. The LGA1155 processor socket can be used with both 32nm and new 22nm Intel processors (codenamed Sandy Bridge and Ivy Bridge, respectively). For most modern boards it cannot be said that there are many free space and it will be easy to install a cooling system of any format. The product in question is no exception to this rule, but everything is arranged according to the standard, and boxed coolers will of course be installed without problems. And if you are planning to purchase something larger and more efficient, we recommend that you first make sure that it can be installed.
This model has four slots for DDR3 RAM. The manufacturer talks about the possibility of operating at frequencies up to 1200 MHz (DDR3-2400) inclusive in overclocking mode. XMP profiles are supported - in particular, Kingston test modules worked without problems in their “native” DDR3-2133 mode (it was enough to change only one parameter in BIOS Setup). The latches on the slots are “one-sided”, which is intended to simplify the installation of modules, although the efficiency can be argued. We didn’t forget about the MemOK! button, which will help start the system if “not very compatible” memory modules are installed.
The configuration of expansion slots is not simple. Differences in color markings do not help to understand. There are two x16 PCIe slots connected to the processor and capable of operating in x16 mode with one video card installed in the first slot, and in x8+x8 mode with two video cards. These ports support version 3.0 standard if the appropriate processor is installed (this is confirmed by the use of standard-compliant ASMedia switching chips). The location of these slots allows cards with three-slot cooling systems to work. The third slot of x16 format version 2.0 works through the chipset and supports the maximum x4 mode. According to the manufacturer, it shares chipset lines with other slots (both PCIe x1) and external controllers (internal USB 3.0 and SATA 6 Gb/s ports on ASMedia chips). So, when using all devices to the maximum, you can only expect x1 mode from it.
The last pair - PCIe x1 slots - are located on both sides of the “main” graphics slot. So one of them will be free in any configuration (unless a large processor cooler interferes), and the second in most cases will not be available when installing an external gaming video card, since most of them have a dual-slot cooling system. In addition, these ports share PCIe lanes with the third PCIe x16 slot, and the second of them also with an external SATA 6 Gb/s chip.
Numerous external controllers and a large set of expansion ports make full use of the 8 PCIe 2.0 lanes available in the chipset. We also note that this board supports LucidLogix Virtu MVP technology (we wrote about LucidLogix Virtu), designed to increase performance graphic applications thanks to the combined use of integrated and external video cards, although, in our opinion, it is more convenient to purchase a more powerful external video card than to rely on this function.
An 8 MB BIOS chip is installed on the socket, but in most cases this is not useful - this board has USB technology BIOS Flashback. It allows you to restore completely “dead” firmware from a flash drive with an image plugged into a dedicated USB port. For this, a specialized chip on the board is used. True, you will have to open the case to access the button to start the recovery process.
Like many other ASUS motherboards, the P8Z77-V Pro has special LEDs that can help identify the cause of boot problems. Moreover, this does not require a long study of documentation and codes - indicators are located near all critical elements (processor, memory, video card port).
Most of the motherboard's connectors are located along its bottom edge (left in the photo). Moreover, they occupy it almost completely (except for the two connectors missing in this modification of the board). This may make it difficult to access the BIOS emergency recovery button. The CMOS reset jumper is also not very conveniently located - too close to the connectors.
Power and cooling circuits
Connection to the power supply occurs using standard 24-pin and 8-pin connectors (working with a four-pin ATX12V connector is allowed). Several Digi+ chips are used to manage the power supply to system components. The manufacturer calls this “Dual Intelligent Processors 3” technology. In total, 12 phases are supplied to the processor, four to the graphics core (in in this case we are talking about the operation of an eight-channel PWM controller with phase doubling), and two for RAM.
The processor power circuit elements near the socket are covered with relatively small aluminum radiators about 25 mm high. Note that their design is complemented by plates on the reverse side printed circuit board. There are no heat pipes here, which is more good than bad. You can also see a heatsink with a complex shape of the upper surface on the chipset chip. Its height is only 12 mm and it will not interfere with the installation of expansion cards - except for access to the latches of the PCIe x16 slots. This cooling system configuration is more than sufficient for the model under consideration. In tests with an overclocked Intel Core i5-2500K processor, we directed the flow from a leisurely 120 mm fan to the power radiators, since the processor was equipped with a liquid cooling system. Under these conditions, their temperature did not cause any concern.
To connect fans, the board has as many as six connectors - “double” for the processor and four for the case. They are all four-pin and support automatic speed control, which will create an efficient and quiet system. Let us note the implementation of a new one in this board unique technology Fan Xpert 2. It is able to provide the required temperature conditions while maintaining a low system noise level. To do this, after assembling the PC, installing and connecting all fans, you need to start special program, which will automatically calibrate the operation of the fan system: it will be able to determine the effect of each fan on the temperature system components and suggest the optimal operating mode.
In this section we will also mention the presence of TPU and EPU switches and indicators on the board. The first activates the automatic system overclocking function using the chip of the same name. You can use it after downloading operating system through a proprietary utility. The EPU is designed to reduce system power consumption by dynamically managing power circuits.
BIOS
The BIOS is implemented using UEFI technology and is based on AMI code. It allows mouse control (although you can't do without a keyboard) and has several localization options. You can’t look at the Russian one without tears - as if in China there is only one version of the Russian font, which can often be found in “nameless” smartphones.
The first page that the user sees after entering BIOS Setup is an implementation of a simplified version of “EZ Mode”. Here you can check the configuration of the processor, memory, hard drives, view monitoring data from sensors built into the board (temperature, voltage, fans), change the boot order and select one of the “optimization” modes for processor parameters - “eco”, “normal”, “optimal for ASUS version".
To access the full set of settings, you need to switch to the “Advanced Mode”. It traditionally contains sections:
- Main - displaying the BIOS version, setting the time and date;
- Ai Tweaker - settings of frequencies, voltages and modes for overclocking and optimizing the system;
- Advanced - setting CPU/PCH/SA parameters, setting up SATA and USB, external controllers;
- Monitor - monitoring system sensors, setting up Q-Fan to control fan speed;
- Boot - OS boot parameters, device selection;
- Tool - access to the BIOS EZ Flash firmware utility, managing overclocking profiles, displaying information from SPD memory modules (including XMP).
We do not recommend that novice users go into Ai Tweaker; at first glance, there are about a hundred parameters there. Moreover, effective overclocking can be carried out using a proprietary utility from Windows. The remaining points are quite simple and do not cause any problems with finding the necessary options.
Functionality
The most space on the rear panel is occupied by video outputs - there are four of them for every taste: VGA, DVI-D, HDMI, DisplayPort. It is difficult to say whether such a configuration is really in demand, but the fact that no adapters are required to connect any monitor can be considered an advantage. The PS/2 connector should have been scrapped for a long time; it is better to install another pair of USB or eSATA instead. By the way, this board has none of the latter. This is slightly compensated for by the fact that 4 USB port correspond to version 3.0 of this interface. Moreover, two of them are chipset-based, and the second pair works from an external controller. USB ports 2.0 are implemented by the chipset controller.
Audio outputs and network are standard - analogue minijacks for 7.1 configuration, digital optical output S/PDIF-Out, RJ-45 port with built-in indicators. A separate place is given Wi-Fi controller for connecting an antenna and an operation indication LED.
Despite the use of the modern multifunctional Intel Z77 chipset, the board in question has many additional controllers that add new functions and expand existing ones. Full list comprises:
- two USB 3.0 controllers based on ASMedia ASM1042 (PCIe x1) chips, each with support for 2 devices, two ports are located on the rear panel, two are on the connector of the bracket for connecting to connectors on the case;
- integrated audio based on the Realtek ALC892 HDA codec in 7.1 format, with an optical S/PDIF-Out connector on the rear panel of the board and an additional S/PDIF-Out connector on the PCB;
- gigabit network controller based on a MAC controller in the chipset and Intel PHY;
- PCI bus controller on the ASMedia ASM1083 (PCIe x1) chip for implementing two slots;
- SATA controller ASMedia ASM1061 (PCIe x1) with support for two internal SATA 6 Gb/s ports.
The motherboard has eight SATA connectors for connecting storage devices. Of these, six are chipset, two of which support interface speeds of 6 Gbit/s. The remaining two are implemented on an external ASMedia controller and also support 6 Gbps speed. The ports are located near the edge of the board at an angle, so that their cables will not interfere with expansion cards. Color coding makes it easy to identify the port type. An external eSATA port can be implemented by connecting the included bracket for the rear panel of the case (the connector from it is plugged into any port on the PCB of your choice, providing the speed and functionality of the eSATA port that you need “from the back”). The chipset controller supports RAID 0, 1, 5, 10, Matrix RAID and Intel technologies - Smart Response, Rapid Start and Smart Connect. By the way, ASUS decided to offer its own utility for using an SSD as a cache for a hard drive.
The built-in audio codec implements standard modes with connection to analog outputs up to 7.1, and also supports digital audio, including HD tracks in BD and output via standard HDMI.
The Z77, for the first time for Intel, has built-in USB 3.0 controllers (remember that they work as 3.0 today only in Windows 7, since only there are corresponding drivers for it). But ASUS decided to add a couple of external controllers. As a result, the user receives four version 3.0 ports and two version 2.0 on the rear panel, as well as connectors on the board for another four 3.0 ports and eight 2.0 ports. The board supports the USB 3.0 UASP standard (you can read more about this technology in the ASUS P9X79 Pro review) for ports based on ASMedia chips, as well as fast charging mobile devices (USB Charger+).
One of the innovations in this line of motherboards is the inclusion of a wireless module. To be honest, the implementation, in our opinion, was chosen somewhat strangely. Today there are good USB controllers that provide high speed operation in the 802.11n standard. They are easy to select, connect and use. But ASUS went its own way - a standard half mini-PCIe format card is installed in a proprietary adapter, which is placed on the motherboard in a special slot between the rear panel connectors and secured with a screw on the reverse side. The antenna (or several) also uses microconnectors of its own, original format. As a result, the user faces many restrictions - you cannot install another board, it is difficult to replace the antenna, you cannot use this product with other devices. Perhaps it is last point and became the reason for such a design. The P8Z77-V Pro uses a single-channel, single-band Qualcomm Atheros AR9485 chip with support maximum speed connections 150 Mbit/s. Note that other motherboards in this series also have more productive solutions.
The presence of two standard PCI slots on the board will be of interest to users who need to use expansion cards of the old standard.
Conclusion
The announcement of a new chipset and a new line of processors has once again spurred manufacturers to update their products. Wanting to maintain the high status of one of the market leaders, ASUS immediately released a dozen models based on the Z77 chipset. Choosing the right one is not an easy task. And even the presence of a product comparison function on the company’s website helps little in this situation. So we recommend that you write down the exact requirements and “try” them on the solutions presented on the market.
The ATX format made it possible to implement on the P8Z77-V Pro a rather interesting configuration of expansion slots, allowing the simultaneous operation of three video cards. This model also has two PCI slots available, which may be of interest to users who did not have time or were unable to replace the equipment with more modern ones. We note the use of Intel's own network controller, which are considered exemplary, although more expensive, and the presence wireless adapter 802.11n standard (but the lowest configuration). Other additional controllers add four USB 3.0 ports and a pair of SATA to the chipset's capabilities. The remaining parameters of the product are quite consistent with a modern solution for building a high-performance computing system based on Intel Core processors of the past and last generation. Among proprietary programs and technologies, we mention TurboV for system overclocking and Wi-Fi Go! for working with mobile devices.Medium current price (number of offers) of this model in Moscow retail: N/A()
A remarkable trend has long been established in the IT industry: the name of a manufacturing company is made by exclusive, often top-end products, while market positions are determined by the level of sales of mass solutions, sometimes having nothing to do with Hi-End. To what extent does “basic” correspond to this idea? ASUS P8Z77-V, based on the Intel Z77 Express chipset (LGA1155), we will try to understand this material.
To begin with, a few words about segmentation. The ASUS line of motherboards is represented by several series: Maximus– top boards with maximum functionality and a clear focus on advanced users, gamers, and overclockers; single models SABERTOOTH“militarily reliable” and have a very extraordinary design; M-series – these are solutions in the micro-ATX form factor; V– the most widespread and diverse; W.S.(Workstation) – products for creating highly productive workstations; have recently appeared I-boards, a characteristic feature of which is ultra-compact dimensions (mini-ITX). The P8Z77-V model is the basic one in the “people’s” segment. At the same time, it is functional enough to satisfy the needs of even demanding users.
Kit, design and layout features
Motherboard ASUS P8Z77-V supplied in packaging typical for this manufacturer's solutions.
In addition to the traditional set of cables, a plug for the rear panel and instruction manuals, the delivery set includes an SLI bridge (by the way, very rare lately), a module wireless communication and a Wi-Fi antenna.
The board itself is made in the usual blue and black colors.
The line of models based on the Z77 chipset has been refreshed thanks to a change in the design of the radiators - right angles perfectly emphasize the status of the product. The power subsystem is closed by two separate coolers (hurray, finally there are no “marketing” heat pipes!), on the reverse side the MOSFET assemblies are in contact with the heat distribution plates.
The board itself has room for three PCI-E x16 slots (the two bottom ones can only be used at half speed or lower, depending on the configuration), two PCI-E x1 and, quite remarkably, two PCI.
The rear panel is moderately ascetic, although in fact it contains an excellent set of connectors by modern standards: PS/2, two USB 2.0, four USB 3.0, RJ45, S/PDIF, a full range of video outputs and connectors for connecting an eight-channel audio subsystem. The contact group for installing the wireless communication module is clearly visible. Speaking of video outputs, the presence of DVI, HDMI, DisplayPort will allow you to very flexibly configure image output to the monitor and, if necessary, do without a discrete video card.
The board has room for eight SATA ports (half of them have a stated data transfer speed of 6 Gb/s).
Near the 24-pin power connector there is a MemOK button (allows you to load safe DRAM settings), an LED located there also reflects the completion of the module initialization procedure, if necessary signaling problems in the operation of the RAM.
Note that, unlike more sophisticated models, the ASUS P8Z77-V is content with only one eight-pin CPU power connector (however, it is sufficient even with intensive overclocking of the processor).
Near the block for connecting the front panel buttons there are two microswitches - TPU and EPU, which activate the corresponding technologies when the board is operating.
In progress
To check the capabilities of the mother ASUS boards P8Z77-V we conducted a series of tests aimed at determining the system’s customization capabilities and ability to work in forced mode.
Before we begin the actual testing, let's briefly look at UEFI.
Briefly, because there are no fundamental differences in the firmware of the model in question from that used in other ASUS solutions.
We were pleasantly surprised by the limits of regulation of the supply voltages and the settings responsible for the speed of the memory subsystem - they are similar to those of the one we previously reviewed and which received very flattering reviews.
Traditionally, we are greeted by a welcome screen containing only basic settings– beginners and ordinary users will have something to look at and, within minor limits, change the CPU operating parameters, fan speed, etc. The F7 key opens the way to more precise system settings - it is followed by the output of the classic BIOS menu based on AMI microcode.
Many users will probably be interested in the nuances of installing large super coolers on this board. In this regard, ASUS engineers did their best: the elements of the power subsystem are located at a sufficient distance from the processor socket, and the radiators, despite their massiveness, are low enough to at least somehow interfere with the computer assembly process. Perhaps a memory module installed in the slot closest to the socket will support the fan of a huge “tower”, but this is already a design feature of the CO.
A quick comparison of the performance of a PC assembled on the basis of the board in question and the Maximus V GENE model showed no differences in either 2D or 3D tests. However, this is quite natural, considering that both boards use the same chipset – Intel Z77.
Imbued with the informative UEFI and the excellent range of adjustment of basic parameters responsible for performance, the first thing we did was to overclock the RAM. Unfortunately, the attempts were not particularly successful - the DDR3-2400 divider turned out to be inoperative, the board did not always start in DDR3-2133 mode, and the OS booted every other time. By installing a lower memory multiplier and overclocking the base frequency, we managed to overcome the 2000 MHz mark (8-11-8-24-1T), but hardcore overclockers should wait for the update ASUS firmware P8Z77-V, which eliminates this shortcoming. However, it is possible that the product in question has an artificial limitation on the overclocking potential (you have to at least somehow diversify the top products, right?).
At the same time, overclocking on BCLK pleased us - we easily conquered 109.6 MHz.
In the process of repeated reboots and changes to the UEFI settings, the POST indicator is sorely lacking, which found a place only in more expensive and aggressive products. The initialization of the CPU and RAM is indicated only by the LEDs located near the RAM slots. Despite the use of the MemOK and BIOS Flashback buttons (it’s easy to guess what they are responsible for), an archaic jumper is used to reset the firmware settings, which is also not duplicated on the rear panel. Therefore, it is best to overclock a PC based on ASUS P8Z77-V in a case with the side wall removed. We no longer find fault with the lack of Power and Reset buttons, although they have a place on competitor boards even in a much more budget segment.
Results
The basic model of the mass class ASUS motherboards performed quite well. It has everything and even more - the presence of a complete Wi-FI module was a pleasant surprise for us. In this context, the manufacturer should work on a system for marking its own products - the names of many boards equipped with a wireless module use the appropriate suffix, and the simple “P8Z77-V” does not mean anything to the average user until they get to know the characteristics and reviews.
What would you like to improve in this product? The first is the control buttons and POST indicator, which are just begging to be found on the RSV. And if you can still do without the latter, then the first (at least the reset key BIOS settings instead of the obsolete switch) is a must. The second thing the P8Z77-V board lacks on the way to ideal is overclocking capabilities. While very strong in BCLK overclocking and system tuning capabilities, the model under review is not at all impressive when boosting RAM. However, if ASUS engineers listened to our wishes - how would the P8Z77-V be fundamentally different from the Maximus V GENE and Maximus V Extreme? You are right - nothing (we don’t take into account the specific accessories that come with “maximum” boards - for most users their presence is not critical). And so, there is room for development!
Anyway, ASUS P8Z77-V exceeded our expectations - a fee that should be " workhorse”, marks the category of “thoroughbred horses”. With the price of the model in question at $190, its purchase seems to be quite a profitable investment - it is unlikely that for this money it will be possible to find a more functional solution.

On April 23, many interesting events took place. For example, in 1956 Elvis Presley's first concert took place in Las Vegas, and in 1982 the legendary ZX Spectrum appeared. And in 2012 a new generation of CPU appears Intel Ivy Bridge, the first mass-produced processors manufactured using 22 nanometer technology. A chipset was released to support them Intel Z77, the features of which I will talk about using the example of a motherboard ASUS P8Z77-V PRO.
Key differences between Intel Z77 and Intel Z68:
- Built-in USB 3.0 controller
- PCI Express 3.0 support
- Supports displaying images on three monitors simultaneously (using third generation Intel Core)
There are three chipsets in total: Intel Z77, Intel Z75 and Intel H77. The differences between them can be seen in the diagram below. The Intel Z75 lacks Intel Smart Response technology, and the Intel H77 lacks overclocking capabilities.
The seventh series chipsets claim support for PCI Express 3.0, although the controller itself is located inside an Intel Ivy Bridge processor. The main difference is the doubling of bus throughput. Such improvements were made after changing the encoding algorithm, namely by reducing redundancy.
It should be noted that Intel has abandoned the P chipsets and thus each of the chipsets supports image output from the integrated graphics core.
However, there is enough theoretical material on the Internet, it’s time to get down to practice.

The motherboard is delivered in a cardboard box decorated in black colors. On the front side there are several pictograms that tell about the features of the board. Support for NVIDIA SLI, AMD Crossfire, Lucid Virtu MVP, UEFI BIOS, Wi-Fi GO!, USB 3.0 Boost is noted here. Particularly highlighted is the SmartDigi+ technology, which includes additional TPU and EPU processors - the first is responsible for overclocking and tuning the system using the AI Suite II utility, the second is for optimizing power consumption according to the current system requirements.
The board kit corresponds to the PRO level - in addition to the usual plug, disk with software and cables, ASUS equipped the P8Z77-V PRO with an SLI cable, a Wi-Fi GO! module, a remote panel for two USB 3.0 ports and a set of Q-Connectors.
The design of the board is traditional for the latter ASUS series– on the black PCB there are plastic and aluminum elements of four colors – black, blue, light blue and pale white. The PCI-Express slots are located far from each other, which should not create difficulties when installing two video cards with massive cooling.
To cool the chipset, an aluminum radiator with a decorative plate is used, on which the ASUS logo and the name of the proprietary technology Dual Intelligent Processors are printed.
The SATA ports are rotated 90 degrees so as not to interfere with the installation of a long video card. Of the eight ports, four support SATA 3 Gb/s and four support SATA 6 Gb/s (two blue using the optional ASMedia controller and two white using the Intel Z77).
Expansion options include 3 PCI-Express 16x, 2 PCI-Express 1x and 2 PCI slots. Only one of the three 16x slots is full-fledged - if you connect one video card, all 16 lines will be available to it. When installing two video cards, the 8x+8x PCI-E 3.0 mode will be enabled, which is equivalent to 16x+16x PCI-E 2.0. The bottom (black) slot will always operate in 4x mode regardless of the configuration of the first two slots.
The sound is implemented using the Realtek ALC892 chip, which is very popular among board manufacturers. Audio output in 7.1 format is supported. Subjectively, there were no negative feelings when listening.
The network interface is implemented via an Intel 82579V gigabit network controller.
In the lower right corner there are two switches: EPU - responsible for saving power and TPU - which turns on the auto-overclocking function on the board (my processor was automatically overclocked to 4.2 GHz).
The processor is powered using a 12+4 circuit. 4 phases are responsible for the built-in graphics core, the remaining 12 for powering other processor units. Power is supplied via an 8-pin EPS12V connector. The RAM power supply has two phases.
Cooling of the power circuits is carried out using aluminum radiators.
The following ports are located on the rear panel:
- 2x USB 2.0
- 4x USB 3.0,
- HDMI;
- DisplayPort;
- optical S/PDIF;
- RJ45;
- six audio jacks.
BIOS
The ASUS P8Z77-V PRO motherboard uses UEFI BIOS. This is already common practice for many manufacturers. In fact, using the mouse when setting up is very convenient.
Nothing new has been invented; you can see the screenshots below.
The main EZ Mode screen displays brief information about the installed processor, the temperature of the CPU and motherboard chipset, and the voltages on system components. The user can choose one of the presets - Quiet, Normal or Performance. You can also select the boot order on this screen. By pressing F7 we go to Advanced Mode.
The first screen is a reference screen - information about time, BIOS version, processor, memory size.
Ai Tweaker Screen - fine tuning systems - frequencies, voltages, memory timings.
The Advanced tab contains management of additional processor technologies (disabling HyperThreading, virtualization), and management of additional controllers.
The Monitor tab displays information about fan speeds, voltages and temperatures of system elements.
Branded utilities
Among the utilities, it is worth noting TurboV EVO for overclocking the system and controlling voltages.
It is possible to automatically overclock your computer.
For experienced users, there is the option of manual configuration.
Power management - for overclocking, you can increase the characteristics or, conversely, put the system into “green” mode and save energy.
The FAN Xpert2 program will independently adjust the fan speed in the system.
