Introduction


DSC_0033

The capabilities of ITX motherboards have progressed at an exponential rate and easily provides the overclocking prowess, connectivity and stability required without making too many concessions compared to their ATX counterparts. Furthermore, the huge popularity of small form-factor LAN cases like the BitFenix Prodigy have made ITX systems a more viable proposition. However. feature-laden ITX motherboards traditionally incur a significant price increase as consumers pay for the convenience of more compact PCB designs.

ASUS has bucked this market trend and launched the aesthetically pleasing Z170i PRO GAMING motherboard around the £130 mark. This is an alluring price, given the SupremeFX audio, excellent software package and intuitive UEFI BIOS. Additionally, the 1151 chipset allows for large frequency overclocks and massive DDR4 memory speeds. When the single PCIe x16 slot is populated with a premium graphics card, you should be able to create a stunning portable gaming system which ekes out every inch of performance. Size isn’t a contributing factor during synthetic benchmarks and I expect the Z170I PRO GAMING to be quite competitive when compared against its ATX-based larger brother.

On the rear, we can see the LED audio path, heatsink screws and M.2 connector. When handling this section, the motherboard’s rigidity and reinforced construction becomes quite evident.

DSC_0022

In terms of connectivity, the motherboard contains a straight USB 3.0 header, SATA Express, four SATA ports, 24-pin connector and 3 fan headers. This provides enough options to connect a boot SSD and selection of high-capacity mechanical disk drives. From this image, we can admire the premium capacitors which can withstand temperature variation between -55°C and 105°C. This is a staggering 110% better than the industry standard and prolongs the motherboard’s longevity under stress.

DSC_0026

The back I/O features a PS/2 port, two USB 2.0, DisplayPort, HDMI, RJ45 Ethernet, two USB 3.1, WiFi, and standard audio connectors.  I’m pleased to see the emergence of multiple USB 3.1 ports given the staggering maximum bandwidth of 10Gb/s. The i219-V Ethernet is protected by ESD guards and reduces CPU workloads compared to other networking solutions.

DSC_0028

ASUS’ SupremeFX audio is based on the Realtek ALC1150 chipset while opting for premium Nichicon Japanese audio capacitors and a stainless steel EMI protection cover. Additionally, the SupremeFX shielding divides the PCB into two sections to reduce electrical interference. The integrated headphone amplifier supports audio hardware with up to 300Ω load impedance and offers superb clarity under high volume. Overall, the audio is stunning for a motherboard of this price and negates the need for a dedicated soundcard. This is essential when you factor in the ITX form factor’s limited room for only one PCIe slot.

Memory

For our memory tests, we use the built-in memory benchmarks in AIDA64 Engineer and SiSoft Sandra. For more details on each of the benchmarks please see here and here respectively.

Storage

To test the storage performance in our motherboard reviews we use AIDA’s Disk Benchmark utility built into their AIDA64 Engineer Edition software package and run linear read and write tests. We run each of the benchmark tests on a SATA III, USB 3.0 and M.2 device. For SATA III testing we use a SanDisk Extreme Pro 240GB, for USB 3.0 testing we use the Supersonic Magnum 256 GB USB 3.0 flash drive and for M.2 testing we use Plextor’s 256GB M.2 M6e SSD. The drives are always formatted before use.

Networking

For our networking tests we connect the test system up to our Intel Gigabit-enabled ASUS Rampage IV Extreme X79 motherboard test system through the ASUS RT-AC68U router and run our tests. We opted for this over a direct point-to-point connection because we wanted to simulate real-world performance. For our WiFi tests we do the same except we connect the test system to the ASUS RT-AC68U router via WiFi at a distance of 2 metres from the router. The testing software we use for these are LAN Speed Test Lite and Passmark, available here and here respectively.

Lan Speed Test

LAN Speed Test was designed from the ground up to be a simple but powerful tool for measuring file transfer, hard drive, USB Drive, and Local Area Network (LAN) speeds (wired & wireless).  It does this by building a file in memory, then transfers it both ways (without effects of windows file caching) while keeping track of the time. Download the free Lan Speed Test Lite utility from here.

PassMark

The PassMark Advanced Network Test (which is part of PerformanceTest) is designed to test the data transfer rate between two computers both of which must be running PerformanceTest. One of the computers must act as the server and will sit waiting for a connection. The other computer acts as a client. It connects to the server machine and sends data to it for the duration of the test. You can download a trial version of PerformanceTest from here.

Power Usage

To measure power consumption we, use a “killawatt” meter and measure the total system power draw at the wall. We run three different use-case scenarios for 5 minutes and take the average reading.

RightMark Audio Analyser (RMAA)

RMAA suite is designed for testing quality of analog and digital paths of any audio device. The results are obtained by playing and recording test signals passed through the tested audio path by means of frequency analysis algorithms. A more common mark is also provided for those unfamiliar with measured technical parameters. Available here. We run the RMAA test using a 3.5mm to 3.5mm cable connecting the line out to the line in to test the quality of the motherboard audio codec not any external audio devices. We run the complete playback and recording test at default settings and then get RMAA to interpret the results giving the below outputs. We sync the playback and recording audio devices to the same setting as the test for accurate results.

DPC

DPC is a Windows tool that analyses the capabilities of a computer system to handle real-time data streams properly. It may help to find the cause for interruptions in real-time audio and video streams, also known as drop-outs. This software is available for download free here.

wPrime

wPrime is a leading multithreaded benchmark for x86 processors that tests your processor performance by calculating square roots with a recursive call of Newton’s method for estimating functions. wPrime is a free utility that is available for download here.

Cinebench R15

Cinebench is a widely respected benchmark for testing the performance of x86 CPUs. The program allows you to test single and multi-threaded performance as well as GPU performance by rendering with Open GL. Download here.

3D Mark

The new 3DMark includes everything you need to benchmark your hardware. With three all new tests you can bench everything from smartphones and tablets, to notebooks and home PCs, to the latest high-end, multi-GPU gaming desktops. Download here.

BIOS and Overclocking


ASUS’s award-winning UEFI BIOS is remarkably simple to navigate and categorizes common tasks into the EZ Mode for beginners. Here, you can monitor the CPU core voltage, temperature and adjust the boot priority. Furthermore, XMP is enabled within two clicks and each fan’s RPM values can be tweaked using the QFan control software.

151020232535

There is an EZ Tuning Wizard which asks a number of basic questions about your system and sets parameters to automatically set a sensible overclock. Although, finding the limit of your CPU manually and adjusting the voltage is highly recommend. Nevertheless, it’s a great option for users who feel uncomfortable with the overclocking process.

151020232915

The BIOS gauges the required performance enhancements depending on your typical usage scenario.

151020232943

Once complete, you need to select your system’s cooling apparatus which gives an indication about typical load temperatures.

151020233010

Then, the software explains the CPU and memory performance enhancements in a statistical way.

151020233029

ASUS’ Q-Fan control is an absolutely wonderful addition and contains a number of profiles designed to optimize fan RPM values. The options means you can prioritize silence over raw cooling performance or allow the BIOS to determine a suitable balance. Additionally, the BIOS features a manual mode and graphical chart to easily set a customized fan curve.

151020233058

The BIOS utilizes the three default profiles which alters noise, power consumption and performance.

151020233201

The first primary tab lists key information about your system, the BIOS revision and other rudimentary tasks. Also, the Hardware Monitor on the right is beautifully positioned and constantly in view while adjusting settings.

151020233319

In terms of overclocking options, the AI Tweaker is extraordinarily detailed and features a number of advanced overclocking tweaks. While this isn’t necessary for most people, the BIOS caters to extreme overclockers without making the menus too daunting.

151020233339

Further down the menu is a section for voltage control to maximize stability when benchmarking and making acute BLCK adjustments.

151020233510

The Advanced tab houses a number of settings if you want to change the attributes of many integral devices. Personally, I would leave the majority of these on the default setup.

151020233545

The Monitor tab displays a comprehensive array of voltages, fan speeds, and various temperatures. This is useful when performing diagnostics and maximizing your CPU’s potential.

151020233557

Disabling Fast Boot is recommended if you spend a lot of time in the BIOS working towards a very ambitious target frequency.

151020233853

Updating the BIOS via ASUS EZ Flash 3 Utility is a breeze and should only take a few moment to complete.

151020233859

You can either manually download the BIOS file and transfer it to a USB stick or proceed with the update directly over the internet.

151020233913

The Exit tab allows you to restore the BIOS to default values or save any changes.

151020233923

In addition to the predefined tabs, you can fully customize the Favorites menu to quickly access essential commands. This is fantastic if you only want to focus on the Multiplier, core voltage and CPU monitoring to perform a fast yet stable overclock.

151020234022

If I was using the motherboard on a daily basis, the Favorites tab would dramatically reduce the average time when fine tuning a manual overclock.

151020234045

The Quick Note overlay is incredibly useful when noting down small voltage adjustments and memory timings.

151020234214

Overclocking 

The overclocking procedure is a doddle and revolves around a multiplier increase of x48 and core voltage bump to 1.504v. I did attempt to reach a frequency of 4.9GHz but this was beyond the thermal limitations of this chip due to too much voltage. Additionally, the CPU requires over 1.5v to remain stable but this follows the pattern of the latest motherboards we’ve previously tested. Thankfully, the process is so simple, anyone could do it with a patient and analytical approach.
