I upgraded to a 13700KF about a week ago and have been tweaking my overclock of it ever since. I got it stable at 5.5GHz all P-Cores with E-Cores disabled. I also overclocked my RAM from 3600MHz CL16 to 3900MHz CL17.
This configuration was rock solid stable, passing hours of Cinebench, Y-Cruncher, TestMem5, Realbench.
Everything was going fine until I decided to see if I could get my RAM stable at CL16 with 1.45V. I managed to get this stable but then the next day, I started to get blue screens on Windows.
It has gotten to the point now where I can only get the system stable at 5.1GHz all core, even opening applications at anything above this will cause the system to crash. I have clean installed Windows twice but the issue persists.
The weird thing is that the RAM does not seem to be affected at all, I'm still using my 3900MHz CL17 overclock and even the CL16 1.45V overclock is still stable, it is only the core ratio that is affected.
I'm wondering if using 1.45V on the RAM has degraded the CPU, even though it was only using that voltage for a day. That is the only explanation I can think of as to why there has been such a massive drop in the capabilities of the CPU.
This is extremely frustrating and any help is appreciated.

Not stable at stock is a very bad sign. Load BIOS defaults, save and just test (check voltages and temps are safe). Don't set XMP or anything. Check all voltages and temps read fine in BIOS or in HWiNFO64.

Post the voltages, temps and settings you are getting in BIOS at stock.
