If I check CPU,Cache, and FPU... she fails in seconds and this is @ "AUTO" vcore, which is 1.325ish, I have LLC @ lvl6. Never had an intel cpu fight me like this. My 9900k was EASY... set 1.25v all core OC @ 5.0ghz and that was it... This 10900k is a different animal
Oh that is easy then.
It (probably) means your IMC is not stable.
Something is possibly wrong with your VCCIO/VCCSA or VDIMM values with respect to your DDR and hyperthreading.
It could ALSO be defective RAM. Or at worst case, a defective CPU. These are very unlikely but possible.
Can you pass these tests at 5 ghz or 4.9 ghz?
Also can you please lower your cache ratio to x43 and test the original voltage again?
There is a complicated relationship between hyperthreading and the IMC/L3 cache.
Try either lowering your IO/SA voltages (keep them within 5mv of each other), down slowly, 5mv at a time, to 1.10v / 1.15v, and also try raising them up 5mv at a time slowly, up to 1.40v/1.45v and test.
(this is safe for testing). Shamino did it himself on his CPU. Hell, buildzoid had it even higher in his 10900k video.
I am still concerned why your VID and CPU Package Power is missing however. It's like your CPU can't communicate with the VRM....
