Hi guys,
My friend bought himself the Pentium D 805, and can't get it stable past 3.2GHz (I say stable, but in general Prime95 only runs for an hour before failing - so not really stable). The temps on the CPU never goes above 45C, so I know that is not the problem. Even increasing the CPU voltage does nothing! When looking at the hardware monitor included with his Gigabyte 955X Royal Mobo, it shows rather large variations in voltages on all the rails. The +12V rail for instance fluctuates between 11.68 and 11.49 V quite randomly.
He has a Thermaltake Purepower 560W PSU, and I'd just like to know whether the PSU voltage fluctuations is causing the CPU to not be stable, is it the PSU that is crappy, or could it be the power regulator card (that slots into the mobo next to the CPU socket) dying?
Should he get the Antec TruPower 550W PSU, or could the fluctuations be explained by something else than his current PSU?
Thanks
