I have a system where any time I try to enable XMP, it posts, but about 30 minutes to an hour into Windows 11, I get the BSOD. I'm not sure if there are any other settings that might need to be changed in the BIOS to run stable, but if anyone has any advice regarding things to try, I'd love to hear them. My current system is:

Asus ROG Maximus XIII Apex BIOS 1402
i9-11900KF (used AI OC and am running at 5.1Gz)
MSI Coreliquid K360 cooler
64GB G.SKILL SK Hynix F4-4600C20-32GTRS
EVGA GeForce RTX 3080 Ti XC3 Ultra Hybrid Gaming
a couple of Samsung 2TB 980 Pros
Asus ThunderboltEX 4

I built this system the lazy way and decided to use closed loops instead of spending my time fiddling with fittings/couplings/adapters/etc.

If anyone has any suggestions, I'd greatly appreciate it! The only thing I haven't tried yet is reset the BIOD back to it's default settings, enabling XMP, and then OC, but I'm not sure how much of a difference this would make. Thanks you!
