ASRock Z170A-X13.1 Non-K OC BIOS

ASRock Z170A-X13.1 Non-K OC BIOS

Support for BCLK Overclocking of CPUs like i3-6100, Pentium G4400, i5-6400, i7-6700 and all other non-K CPUs.

Don’t use this for K-series CPUs.
It might damage your hardware, no guarantees provided.

  • Enter the BIOS and go to the OC Tweaker – DRAM Configuration.
  • Load the XMP Profile to adjust your memory correctly
  • Adjust the BCLK to the level you need
  • Adjust the DRAM Frequency to the correct level. I had to stay below 2800 MHz on the memory to achieve high BCLK clocks
  • Go to: OC Tweaker – Voltage configuration. Set the vCore you want. Stay below 1.40 for 24/7 OC

    I tried this i have the asrock z170 x1, and for some reason it wont let me change the voltage, and it wont let me set it to fixed. I spoke with asrock tech he said i need the version 1.40 bios and thats wat i just flashed my bios 2

    A have a asrock z170a-x1 board, and not the z170a-x1/3.1. This bios is for the 3.1 version of the board only, correct? Is there anywhere I can get the older bios for the z170a-x1 board?

      I lucked out and found a copy of the 1.20 bios for the z170a-x1. I can provide it to this site if they want it.

        The 1.40 bios for the z170a-x1 works. After flashing the bios, on the first reboot, you need to press X at the initial boot up screen (instead of del to go into bios) to enable the Sky-OC feature of the motherboard. After that, it was pretty easy to get my i3-6100 running at 4.4 Ghz, with a +110mV offset. I could probably push it more, but I’m happy with that overclock.
