ASRock Z170 OC Formula Motherboard Review

Jump To:

CPU-Z Benchmark

CPU-ID’s CPU-Z has been a popular freeware utility for a long time, that gathers system information on the PC into one location.  With the latest version 1.73 they introduced a couple of new features.  One of these new features is the integrated CPU Benchmark that provides a score and a Reference CPU that you can choose from a drop down menu.  There are no reference Skylake processors available in the menu, so we chose a similar processor from a previous generation, an Intel i7-4790K running at 4.0GHz.



Legit Bottom Line:  CPUz gave the ASRock Z170 OC Formula a 6.5% edge in performance over the other Z170 motherboard.  Going from 4.0GHz to 4.9GHz we saw an additional 14% increase in the Multi-CPU test for CPUz.

    I’m just gonna outright say it. If you are from Pittsburgh, this is a really tempting board just for the design!


    Maybe I just do not understand the idea of it all, but how are you supposed to have quad graphics cards and still be able to utilize all four cards respectively along with three M.2 drives in a raid??

    Does this not take up more than the available PCI-E lanes allocated for the GFX/disk/HDD’s? I could see with a 2011 socket allowing 40 lanes of PCI-E 3.0 there being no problem…..I just hope someone can enlighten me as I’m always looking at tech just to see what’s avaislble for the ol’upgrade…

      you the real MVP
      maybe this socket will be used for future generation of cpu on this soket, that will have more pci lanes


        I see in the specifications of this particular motherboard here on this review it has an * (asterisk) next to where it explains the PCI-e throughput. It does not however explain what that asterisk means in lieu of the PCI-e lanes in question.

      It seems that each motherboard does it a bit differently. The GB Z170 board specifically mentions that the PCI-E lane and SATA ports becomes disabled, where the ASRock Z170 OC doesn’t mention the PCI-E lanes, but does mention disabling the SATA ports. Another one I’m testing is like the ASRock board, only disabling the SATA ports. That seems to be the most common aspect of the M.2 implementation.


        Nice. And thanks for shedding a bit of light on this for me. Just did not understand the asterisk by the explanation of the PCI-E lanes in the article clipping they took from the manufacturer. I sure there was something elsewhere explaining exactly what that was supposed to mean…

          Sorry, I’ll watch those next time. The * on the PCI-E slots is just that they support NVME as boot drives, nothing to major.

          Ah’thank you….
