5950X / Crosshair VIII Formula (Default settings)
BIOS 2301 (AGESA V2 PI 1.1.0.0 PatchB) : No issues but occasionally i notice some massive voltage and temperature spikes (to 80-85c) @ idle. It is not cooling related, i'm using a Liquid Freezer II 360mm and during AID64 stress test it stays well below 70 degrees.
BIOS 2402 (BETA) (AMD AM4 AGESA V2 PI 1.1.0.0 Patch C): The temperature spikes are gone but there is a *massive* drop in ST (CB20) performance, from 640 points ( BIOS 2301) to 610 +- ( BIOS 2402), i ran the test like 10 times with each BIOS and it happens consistently.
