ASRock Z270 Pro4 Review and test motherboard

ASRock Z270 Pro4 has the best equipment, in my opinion: six SATA sockets, three M.2 port network adapter from Intel and ALC892 codec (!).

ASRock Z270 Pro4: Packaging equipment

It is well framed box, bright subjects, remote from the common dark tones.

More details about ASRock Z270 Pro4 are located on the back side of it: the product photo, the back of the image with the characteristics of the table and the usual emphasis on the model features.

ASRock Z270 Pro4: Appearance

Narrower than the board a couple of centimeters relative to nameplate ATX format width, has an unusual number of attachment points – seven. No auxiliary buttons or indicators no, no lights, too.

In the accommodation Multicontroller on the reverse side of the board there is a small number of electronic components. Apparently, they were there solely on image considerations.

The overall area of ​​the cooler, placed above the Z270, is enough to not worry about temperature limits.

Provided six SATA ports longitudinal type.

There are also increasingly popular triple M.2, the smallest is under the wireless adapter and the other two can be used for connecting drives already.

An additional controller is only one, it is necessary for the implementation of PCI interface. An unusual number of sockets for USB cables with second-generation interface – five (one of them – the single-type), a more recent audit costs one seat for a pair of ports. The device firmware is now sealed, and nearby there is a dedicated socket for the programmer, as it is done on the MSI motherboard.

PCI-E slot Upper uses sixteen lines from the CPU, the other four are working with PCH.

Placement network adapters and sound simple-minded: there is a small number of special capacitors ELNA, no filters, auxiliary op amp.

In the CPU VRM zone is there a finned heat sink, although there is room for a second.

ASRock Z270 Pro4 Review and test motherboard

VRM circuit is a bit simplified variation of the sample can be seen in the structure of the ASRock Extreme4 Z170 . All the same ISL95824 from Intersil Corporation manages three voltage channels for the CPU and two calculated for the GP, although its capabilities are described by the formula 4 + 2 phase. Only three drivers integrated into it, and the two empty seats on the board the individual components. Under the radiator elements are also necessary for the formation of the CPU and IO SA levels.

Thus, there is a pair of “phases” for the CPU, and the third channel is passed to the upper edge of the radiator and works without maintenance. The structure of each line includes twice the number of elements. Build – SM4336NSKP and SM4337NSKP from Sinopower. So, simplified power for the integrated display adapter on each of the two lines there is one and the throttle assembly SM4337NSKP, but SM4336NSKP type already engaged couple, just turned three elements.

Let clamp radiator provided clips, questions to the fingerprint of the transistors on the thermal pads there.

Behind there are only three audio output. Legacy D-Sub implemented by Bridge DP-D-Sub – RTD2168 of Realtek. Bonus for possible wireless network adapter, the system appears ingenuous stand, where will carefully switching antenna.

ASRock Z270 Pro4: Features UEFI

To update the firmware, I took advantage of an integrated part of the UEFI utility Instant Flash.

The base of the settings is called EZ Mode.

ASRock Z270 Pro4 Review and test motherboard

In Advanced mode, you can find a lot more points. The first page will allow to concentrate favorites variables.

When the computer needs to be overclocked OC Tweaker. There are five sections to store settings and harvested several engineers.

From expensive boards novelty is a smaller number of strains available to change the limits, too, began to do much more modest. The remaining points are not enough, there are also several profiles LLC.

On the Advanced page is a tool for working the periphery.

Genuine mechanisms are not as many as could be. Interactive map system functioned without any problems.

The monitoring system has pleased presence of a lot of tension. All you need to break up “in the air”, here it is.

The processor and the third in a row cooler can be powerful, the board has a safety factor of 1 and 1.5 A, respectively. Selection of fan speed change mode can be based on the temperature of the board or the processor. Hull coolers slowed down by changing the supply voltage, the CPU uses the method of changing the PWM duty cycle, and the last connector, you can choose your own method.

The initialization routine equipment is fast, in any case, have a classic set of mechanisms for this column.

ASRock Z270 Pro4: Complete Software

This section will be unusually short. As usual with ASRock, all software maintenance is concentrated in complex APP Shop.

However, for the current product number of tools it is displayed there turned out to be extremely small. I used to date version. Do not disdain marketers to dilute the paint by adding slot machines (slots).

Installing the utilities goes right here.

The presence of brand A-Tuning, where there is a mechanism for setting the system of coolers using the calibration of all devices. Implemented control parameters, including, from here you can activate profiles for overclocking PC.

Provided Restart to UEFI, which allows to get into the UEFI environment immediately after the computer is restarted.

The sound system is satisfied only brand configurator from Realtek, which is not unusual.

In fact, the only bonus is XFast LAN, this product allocates priority among the programs that use a network connection.

ASRock Z270 Pro4: Overclocking potential

In testing involved Engineering Core i7-7700K.

Corporate acceleration start checking mechanism using Optimized CPU OC Setting. For our CPU lower mark, equal to 4.6 GHz, it was relatively acceptable. The voltage was fixed at the level of 1.35, have a memory frequency is 2133 MHz.

Despite the significant drop in voltage under load, advancing the CPU overheating, although the error was not in the system. Engineers would not hurt to use point UEFI AVX Ratio Offset.

Another method is called Advanced Turbo, when setting the graphics card discrete settings it disappears from UEFI, you can activate it from a utility company. Gear Profile 1 tantamount brought the first method, the frequency at the Core i7-7700K, memory accelerated to 2400 MHz, but significantly increased its delay.

Unfortunately, the behavior of the system was no better, using AVX processor overheats almost immediately.

The third way of corporate acceleration (Auto Tuning), as well as on previous generation motherboards, is repelled by the profile of any of the previous two scenarios, but because of the actual malfunction of both, I did not expose the system with additional load.

Acceleration reference frequency is not as simple as we would like. With the overcoming of a value close to 180 MHz, the system cold start conducting a double stage with intermediate hardware initialization powering (ie. N. A double start), and after already working without problems. The more basic increases, the more it becomes such trips, on the border of 250 MHz, the number is still the two, because I’m going to assume taken the mark of 251 MHz relatively stable result for the test systems. Radically big marks, for example 350 MHz, which conquered almost all the boards of the rival camps, immediately lead to boot with safe, regular parameters and displays a message about the need to make edits.

I could not use the options that are identical for the other devices, the catch was in the maximum mark of 1.2 for the CPU IO, usually the value is 1.25 V.

As always, the CPU overclocking svёlsya the search parameters when the voltage is sufficient for stable operation of the system and, at the same time, throttling is not activated. Under the CPU Voltage load noticeably “sink”, although pleased to be the nature of that steady level held steady throughout the load cycle, and not constantly changing. Other profiles LLC, compared with the first to allow an even greater its deviation (decrease) of the set value.

The final rate of 4655 MHz proved. Actions were 1.25 V, while in idle moments happened approximation to 1.3 V. In fact, this I repeated the result obtained with the assistance of ASUS Prime Z270-A.

The temperature points on the board as the one where the elements do without the radiator (which is less), and another where the radiator is (and elements longer), suited to the level of 76 ° C. Radiator warmed to 49 ° C. Consumption kept within the boundaries of 41-193 watts (without taking into account not once seen by the jump, for it is necessary to separately thank Windows 10). Self consumption schedule is relatively straightforward, it is a question only as a plus for the final assessment score.

The real surprise has prepared a test subject in the last test, which was conducted overclocking memory module pair. It was possible to easily conquer the mark of 3751 MHz (at the moment it is a record!). For this event it has been a number of conventional steps. Group delays fixed at 17-18-18-39-2T, increased number of stress. For most memory value greater than 1.5, we do not use (although the board may allow the type of 1.55), and for the CPU IO required were 1.2 (this is the highest possible level); CPU SA content with a value of 1.15 V.

It seems that the secret lies in the scheme of additional delays, but for the average user, these parameters are very difficult to master.

ASRock Z270 Pro4: Testbed

The stand includes:

  • Processor: Intel Core i7-7700K (4,2 GHz);
  • Cooler: Cryorig the Ultimate R1;
  • thermal interface: Noctua the NT-the H1;

  • driver: Intel Chipset Software Installation Utility (, Intel Management Engine Interface (, Intel IGP Driver (, GeForce 375.95 (, PhysX 9.16.0318.

All updates to the OS, available to Windows Update, have been installed. Third-party anti-virus products were not involved, have not been made thin System Configuration, the swap file size determined by the system on their own.

The following applications were used as a test:

  • AIDA64 5.80 (Cache & Memory benchmark);
  • Super PI 1.5 XS;
  • wPrime 2.10;
  • x265 HD Benchmark;

  • Hitman: Absolution (1.0.447.0);
  • Grand Theft Auto V (1.0.877.1);
  • Rise of the Tomb Raider (1.0.668.1).

During the tests, the representatives Intel LGA1151 platform versions of the software are updated regularly. For a possible correlation results are summarized in the comparative table:

ASRock Z270 Pro4: Test results

Before testing activated XMP, more than any modifications to the settings it was not.

Processor operated at a frequency of 4.4 GHz, for any type of load, is 100 MHz less than he had worked on previously tested motherboards using the Z270.

Probably, this fact has served as the symbolic lag in the CAP tests.

The worst results in simple utilities are easily explained by the same root causes.

Integrated system load leads to subtle loss.

Only in Physics scenario, Fire Strike is possible to find the difference among the participants.

High load on the graphics card eliminates the difference in the frequency of the processor on different boards.

ASRock Z270 Pro4: Power systems

Measurements were carried out after completion of all other tests in the “well-established” computer mode, using the instrument of its own design. To create a load profile was used In-place large FFTs composed Prime95 utility (28.10). Calculation produces the mean consumption of the test stand “from the wall” during the eight minutes of the program, and then, after completion of the test, was measured for a minute the level corresponding to the state of system downtime.

In a simple test subject was the most economical ATX-model, but with a load consumption of the stand was the lowest, surpassing even the representative on the basis of B250, although here the memory operates at a speed of 3200 MHz at a voltage of 1.35 V. On the processor it does not exceed 1.25 and support the CPU and IO SA grew up optional 1.28 and 1.22 V.

ASRock Z270 Pro4: Conclusion

First of all, I was pleasantly surprised by the potential of ASRock Z270 Pro4. That only is a record-breaking overclock RAM. It turns out there is some margin for overclocking neskalpirovannogo Core i7-7700K, and in fact subjected to a low-end system even less stress. Excess passport ring bus frequencies are also possible, albeit with some reservations.

The main differences from the more prestigious models are truncated beyond all stress groups, as well as a considerable step for a number of groups, most bitter limitation is a ceiling of 1.2 V for the CPU IO, but to call it a frighteningly small does not. Pretty bleak picture in voltage stabilization, although the behavior of exactly guess the use of the PWM controller from Intersil. Availability LLC profiles are not severely rescues from “sagging” of the voltage, the benefit, it is still a good, flat level, albeit markedly reduced.

ASRock Z270 Pro4 features in the hardware does not have any bonuses in the form of controls and display, no backlight, no POST indicator should also be mentioned here; sound system has no operational amplifier. Quite modest looks set of proprietary utilities.

Obviously, the manufacturer have focused attention on the hardware aspects, paying minimal attention to the rest. The implemented program monitoring will be aware of what is happening. As a result, the ASRock is an interesting model primarily for overclockers on a budget, as well as all those who might be interested in the use of high-speed memory in conjunction with the ordinary processors (without overclocking).
