We also prepared a special video to show you the key design features of the ASRock Z170 Extreme4 motherboard. Enjoy!


CPU Power & Performance

The ASRock Z170 Extreme4 motherboard features a 10-phase power design. This is most likely an 8+2 design, with 8 phases dedicated to the CPU. That ensures a cooler and more efficient power conversion compared to voltage regulator modules (VRM) with fewer phases. Its MOSFETs and inductors are kept cool by large aluminium alloy heatsinks, which helps ensure reliability and longevity of the VRM.

The Z170 Extreme4 uses digital pulse-width modulation (PWM) to control its VRM. The PWM is critical in ensuring a stable power supply. Although high quality (and expensive) analog PWM exists, digital PWM allows for more accurate control of the power frequency and modulation.

ASRock also equipped the Z170 Extreme4 with Nichicon 12K Platinum capacitors, which not only boasts faster response times and lower voltage noise but also a much longer lifespan (12,000 hours @ 105 °C). In general – this motherboard is designed to last.

To support CPU coolers with two fans, or a DIMM cooler, the ASRock Z170 Extreme4 has two CPU fan headers placed at the top of the board, right next to the four DIMM slots. Finally, the Z170 Extreme4 features an external base clock generator, which gives you finer control of the BLCK frequency- in 0.0625 MHz steps. Of course, the utility of such fine control of the BCLK clock is questionable…

DDR4 Memory Slots

The ASRock Z170 Extreme4 motherboard has four DDR4 DIMM slots, their contacts gold-plated to protect them against oxidation and corrosion. Even though the Intel Z170 chipset only supports non-ECC memory, these DIMM slots can accept ECC memory modules – with their ECC capability disabled.

The Intel Z170 chipset only supports DDR4 memory up to 2133 MHz in frequency, but the Z170 Extreme4 allows for overclocked memory clock speeds of up to 3600 MHz with selected modules. It even supports 3866 MHz, but only if a single memory module is installed.
