I've been using the newest BIOs 3004 but was wondering if there's a LN2 specific one available? I know there's a few experts on here that know all about Ryzen at sub zero temps. I'm currently working on R5 3600. Noticed there's some CB & CBB issues, with my CPU it wont boot if below -70c and system attempts to reboot if drops below -170c.. at which point I get q-code 07. I can only get my system to boot when RAM is at 3000MHz instead of rated 3600MHz. https://valid.x86.fr/4egkpq Any help or tips would be much appreciated.
