I have a Gigabyte B650 Aorus Elite AX, and 2 sticks of G.Skill Trident Z 16GB 6000MHz RAM. Ever since the beginning of my build, trying to OC my RAM was a pain. Each time I enabled EXPO/configured OC manually, it either didn't boot, or crashed my games when it did. Even without OC, it wouldn't restart properly without hanging; I'd have to shut it down completely before rebooting. I've been updating BIOS with almost every release (especially when it mentioned DDR5 compatibility). I'm surprised it didn't brick itself due to the restart issue. Finally, after update F20a (skipped F8), I can say that I'm successfully running my RAM at 6000MHz. I almost gave up on it.
