Oh I know what to do, do not mess with risking losing these things, drop your o/c immediately, or at least that's what I'd do. Plus for the sake of maybe a second per frame or whatever, you've got that points monster sitting there in the moat trading water instead of tearing up the slope on the other side.
I didn't have to play with mine and it's an aggressive* one too, at the very edge of what folding allows through trial and error long ago. I've found they run smoothly, better than avg. actually.
* aggressive: 1518 and 1503 vs 1215 clocks on gtx465's
and 2054 vs 1962 on 550ti. I think that one must have been factory o/c'd.
