I have tried 2 different versions of the f6 bios, the one the board came with & one I pulled off the GB site. The latter seems noticeably better. I tried a version of f7 which is probably the worst of the 3.

Another thing I've noticed is that Touch Bios is not 100%. My board was posting incorrect frequency numbers on startup. No changes after a Touch Bios flash. A flash from the bios fixed the issue.

Anybody have any wisdom on A. how to distinguish the different versions and B. which versions perform the best?
