I am thinking I might have a PSU that can not handel my OC'ing. If you have read my other post....Stuck at 4.6.... Tomorrow I will switch to my other FX8150 and try that one. If I still have problems I will run my pumps off my other PSU and see if that help. My question is, I am waiting for my 16gig of Vengance 2133 Ram to return from RMA. I would really like to use that for OC'ing. If I try with the 1600 ram and get it overclocked, will I have to start over with the other ram or just change the MEM FREQ?
