I haven't had any issues on my x670 Aorus Elite AX with bios (F7h) yet. I take that back... when trying to OC it isn't super stable with an all core curve offset anywhere better than -15 or so. But the EXPO settings it took and liked right away.

Looks like gigabyte has changed BIOSes for X670 Elite AX (1.0). F7f is gone replaced by F6c and F6d (the latter having the 1.0.0.4 AGESA version). Wonder what is up with that and if anyone has tested / used it. I would love a bios version that adds mid-boost functionality so my 7950x will go above...
