its not locked? you can adjust ''[AUTO]'' with 'enter' and adjust ''auto'' with +/-
Dude, thank you! I had the same issue as OP, thinking that my board must've been going bad on me because I figure that non-bracketed 'auto' was not changeable. I clicked +/-, lo and behold, it changes! Silly me. Silly us (me and OP). I was at my wit's end with the board, which has been a dream since June. Now off to some OC'ing!
Of course, if the OC Genie works, the board has to be fine, in terms of manual OC'ing.
