So, after a bunch of testing and changing speeds and voltage.. I came out with a stable (or what seems to be, I've done a total of 1 hour of full load stress tests in XTU) 4.8GHz with 1.2v. CPU-Z shows the voltage running at a consistent 1.229v at 4.8GHz stable. From my understanding, it is very rare to be able to run this high of a clock speed at this low of a voltage.. So after these results I assumed I had hit the silicon lottery. Assuming this, I went on to try my luck with 5GHz (which I thought would be extremely easy to achieve, as I hit 4.8 with such a low voltage) and after trying 5GHz at 1.26v, 1.27v, and 1.28v, with the highest 1.28v maxing out at around 1.306v in CPU-Z, about ~5 minutes of each voltage level in the stress test at 5GHz would cause a BSOD. Any thoughts on why I can't achieve 5GHz with a similarly low voltage level? The temps under full load in the stress test max out at about 68c-70c while normally staying around 55c-60c, I'm using the EVGA CLC 280 Liquid AIO cooler for the CPU. Thanks for your time and help in advance.
