Case: Lian Li o11 Dynamic, 6 Corsair LL120 case fans
Motherboard: Gigabyte Aorus Ultra Z390 (latest F7 BIOS)
Cooler: h100i V2 (Stock Fans replaced with 2 Noctua NF-F12 and ran at 100%)
Thermalpaste: Thermal Grizzly Kryonaught
Purchased in September last year (so I am guessing I just had a bad spin at the silicon lottery on the early silicon).
My 9900k will not be stable at stock frequencies with a manual vCore of pretty much anything less than 1.4 v, and at that point I hit thermal issues. I can run it at optimized defaults with the big fluctuations in voltages, but that it is the max performance I have managed for rock-solid stability. I cannot pass a Prime95 small FFTs torture test without adding an AVX offset of 2, even at stock and with the relevantly higher-end cooling solution detailed above.
MCE on and I get BSOD before I can even get past the Windows login screen. Intel Performance Maximizer is not compatible with my BIOS.
Does anybody else have anything even remotely like this? I do not believe the majority of OCs posted on forums are legitimately rock-solid stable, but I must have a lemon!
