Alright im running an asus maximus formula on the latest 1004 bios and no matter what voltages ive changed i cant my cpu stable with prime95 small ffts. Ive increased every voltage. Btw i was previously stable at 450 x 8 (3.6 ghz) at the same settings, to achieve 4.0ghz with my new watercooler i simply increase the mult to 9.0 and increase the voltage. At 3.6 ghz i was stable at 1.2975v, now even when i increase voltage all the way up to 1.5000v i cant even get prime to run for more than a second. To clarify there is no difference in stability when i go from 1.4000v to 1.5000v and any other voltages (PLL,NB,FSB term) do not help. Could i be running out of power? Im running a 750w PSU. system consists of:
Q6600 450 x 9.0 1.4000v not stable
4 gb ddr2 800
asus maximus formula
EVGA 8800 GT duorb
soundblaster x-fi
2x wd 150 gb raptor x 10,000 rpm RAID0
Swiftech watercooling kit
