I just cannot get it to pass prime95/occt/aida64. BSOD(whea) after about 10-15 mins every time at 4.7. one thing I did notice is if I run AIDA64 without ram stress, it doesn't crash. Runs all stress tests fine at stock. I did find out my ram I'm using isn't on QVL. However, like I said, I tried it without xmp enabled. So I'm not sure. Any help would be appreciated. I know silicone lottery said 100% of this chip should be able to do 4.8.
Please RMA the chip immediately.
Since you disabled XMP, it isn't anything to do with RAM at all. Your chip is unstable at STOCK.
You should be able to pass most "basic" stress tests (AIDA64 stress FPU, Prime95 AVX disabled small FFT, Cinebench R20, Realbench 2.56), at 4.7 ghz 1.205v Bios set (dont set 1.20v--there is a bug I don't want to go into) , LLC Turbo, and ALL stress tests (including AVX small FFT) at 1.250v Bios set, LLC Turbo. The fact that you can't do this means your CPU is unstable at stock.
The CPU should, at all auto settings, and at "failsafe" AC/DC Loadline settings (1.6 mOhms AC, 1.6 mOhms DC LL), Loadline calibration set to standard and Vcore set to "Auto", request around 1.20-1.28v at load. These are worst case settings.
The fact that you can't even get stable at 1.35v bios set, LLC Turbo, means your CPU is defective. Please RMA it. Trust me.
