Earlier today I was playing around with a overclock. Nothing major, just 4.4GHz. This was happily configured to run at 1.37v(ish) and it was stable. I thought it was a little high so I decided to see if I could get any lower. At this point, I decided to update my BIOs to the latest in case they gave any positive effects to my overclock. I updated to the latest with no problem. I then set the LLC to high and managed to get the required voltage down a little more - around 1.35v stable. All was good but I decided to see what the stock voltage was again.
I removed the overclock and booted into Windows and saw the voltage in CPUz - it was about 1.27v under load. I thought it was a bit odd, it never was that low before I updated the BIOs! It was normally above 1.3v at least. I ran some stress tests and it appeared stable (for the 20 minutes I tested) however, in CPUz it kept clocking to 3.4GHz every few seconds and back to the stock 4GHz. Turbo was on, but I did not see the CPU clock up to 4.2GHz. This was odd as it never normally did that and the temperatures are fine (60C VRM and 50C CPU).
At this point I decided to overclock to 4.2GHz on stock voltage as I could do this normally on my old BIOs. It then failed when I ran Prime95 in under 5 minutes. It worked before I updated the BIOs
I then tried 4.4GHz and used the exact same settings as I did before (I wrote them down) and a few cores failed.
I then downgraded my BIOs to the one I had in the first place (Version 1302) but the problem persists! I can't do 4.2GHz on stock voltage even though I was able to before.
I have further tried the following to resolve the problem:
Clearing cmos
Several times to reset the BIOs to defaults
TL;DR: Was overclocking fine, updated BIOs, CPU ran at a much lower voltage than normal, was stable at this voltage, tried 4.2GHz on the new BIOs which was fine before I updated, 2 cores crashed. Downgraded my BIOs to the version I was okay with, tried 4.2GHz again on stock but still crashed. Tried 4.4GHz with same settings as before, 3 cores crashed.
I'm not sure what the issue is as my computer has the same software and BIOs as it was before (and settings). Any help is greatly appreciated, thanks
