ASRock’s Z370M Pro4 brings us the lowest price yet on Intel’s top LGA-1151 chipset. Can it perform, can it overclock, and what features does it give up?

Enthusiasts seeking the biggest bang for their performance buck now have an overclockable Z370 motherboard option for about the same price as the locked-down H370. But there are a few catches, beginning with overclocking limits that are imposed by a thermal-throttling voltage regulator, extending to the board’s lack of CPU PCIe bifurcation, and ending with the lack of USB 3.1 Gen 2 capability. That last feature is integrated into the newer H370 chipset, but the extra chip required to extend the feature to Z370 was, apparently, simply too expensive to include at this price level.
