I've recently upgraded the processor in my I-gaming based rig to a 5950X. When running the board with DOCP (XMP), I seem to get spontaneous reboots and cache hierarchy errors including file corruptions. Strangely leaving the board in DOCP/XMP mode and running memtest for a few hours confirms no issues with the memory, but running under this mode in Windows just spells disaster.
Running the machine back in full defaults and running processor specific stress tests (prime95 etc), all seem to show a clean processor. This suggests a BIOS issue of sorts.
Anyone else getting this behaviour? I know the 5000 series run a little hotter than the older 3000 series, but I am definitely within the thermal limits. Running the 2816 bios at the moment, but not keen to go backwards if possible. Any help would be appreciated as I think I have re-installed this rig about 10 times as well as re-seated the processor etc. I only became convinced it was not hardware when all the stress testing I did individually came back clean suggesting some strange issues afoot elsewhere. A quick google around shows other ASUS owners posting in places like Reddit who also have issues like this and have resorted to lowering vcore voltages and turning off PBO.
I should note that PBO when running under XMP guarantees a quick spontaneous reboot, although it is oddly when the processor is not doing a lot. PBO under default settings (i.e. with very slow memory) seems to have a well performing processor, but matched with a slow memory speed really does not unleash what this kit should be capable of.
