Huh. it says ration limit is locked. um...I'd ask ASRock support directly why that is...from what I coudl find, no turbo OC on the board, which is a shame. Silly to not offer that option, but OK.
You MUST fix the "locked" mutli thing. Look for something that says "Limit Max Multi" or something along those lines. Unfortunately ASRock is one of the OEMs I have not reviewed products for yet.
