Just got a 550 and 790X-UD4P. Its unlocked and working at 3.6 now, with 1.5Vcore, and .2v added to NBv and NBvid. Fails OCCT Linpack after 10min. Temps are fine, speedfan, everest, and hwmonitor all report the same, 48C load.

ACC is set to auto -2% for all cores. Is there a guide anywhere on what the ACC settings do, and where they should be set?
