    Can anyone get this board to overclock with a non-k? Doesn’t matter what bclk i put in, it is ignored and stays at 100mhz. Also, is there a chance this board will get the newer bios? (apr 18 version instead of the jan 23) The current version doesn’t have the “beta runner” that the screenshots show.

    I have flashed to version above, set cpu and ring mult to 34 (i7 6700), set bclk to 120 (just as a start), turned on xmp, disabled intel step and boost, set memory frequency to stock freq, upped vcore to 1.3. When i boot into windows and look at cpuz, bclk is still 100.

    Any help appreciated.

      I know your post is a bit old by now, but I can confirm that you can overclock on the Krait 3x.

      I have an i5-6600, running at 4.5 GHz with 1.3V VCore. BLCK is 137, with a ring and CPU mult of 33. I would try disabling XMP; just pick your memory speed from the drop-down menu. In my case, enabling XMP set the BLCK back to 100 MHz every time I tried to boot, so this might be your issue.

      Also, if all else fails, try re-flashing the BIOS. Every time my OC failed and It reset itself, it apparently locked the BIOS again, requiring a reflash. Hope this helps :)

        Hey, Max.

        Are you using the latest BIOS version from MSI’s website (2.5) or the version uploaded by der8auer?
        Some MSI boards (like the mortar) still have NON-K OC on their latest BIOS revisions, despite also including the 0x7C microcode update.

        Thanks in advance.

          Hey Francisco,

          I’m currently using the Version provided by der8auer with no issues (apart from Ubuntu 16.04 refusing to boot for some reason…). I’ll definitely try the MSI version and see how that goes though. Thanks for the Tip!

          Update: Looks like the MSI bios doesn’t let me set the bclk to whatever I like. The maximum value that I can enter is 118 Mhz, which results in 3.9 GHz. Not enough for me, so back to der8auers version for now

            Hey again, Max!
            Thanks for your reply. That saved me some time this weekend, when I went full-blown on my overclocking :p

            Got my 6400 all the way to 4.374Ghz (27x162BCLK) @ 1.325v, rock solid in temps (Arctic Cooling Liquid Freezer 120) and stability, just this weekend. 62% free performance, I’m just beaming.

            Thanks, der8auer, for this, and for the time you took, and for your guides!

    I tried to update the bios on my z170a krait gaming 3x, but i couldn’t find the file anywhere on my flash drive. I am able to see all the folders I unzipped, but not the E7A11IMS.21T file. I have tried every usb port. Please help!!

    Hey Hakon,

    Make sure your usb is properly formatted. unzip the file and put it in its own directory on the usb. Make use you are using a usb 2.0 port on the motherboard or one on you pc case off a usb 2 header. some board from my experience don’t like usb 3 for booting from or loading. could be due to driver limitation. Remember bios is chip level so no software to tell what the usb is really doing to make it simple. If you want a decent oc you may be able to set vcore to offset rather than manual this way your cpu will down volt when it doesnt require full volt to push core beyond the 3.7ghz.
