I've encountered another weird problem with my board and I'm just curious if it was normal.
I was running 4.9ghz avx offset 1, 1.310v core, turbo LLC. This was rock solid stable on 8 hour Prime96 26.6 and Prime96 AVX separately.
I didn't like how loud the fans were in the system so I swapped in some noctua fans, added a few extra ones for higher airflow and all of a sudden my previous settings were crashing left and right.
It's now stable at 1.320vcore all settings the same. Why did I need an extra 0.010vcore to get it stable? I reverted back to my original setup and it was stable again at 1.310 vcore.
