BSOD after changing PSU

northun_munky · 25 May 2009 at 16:57

Got a bit of a strange one here. I've changed my PSU thats in my sig for a thermaltake toughpower 850w. I had to take the mobo out to get the old one out and replace it so I also took the time to lap my q6600 and clean and replace the tuniq tower.

I ran P95 to see how the temps were after lapping. Problem is I'm now getting BSOD using the same bios settings and voltages I used before for 3.4 (425*8, 1.33v under load)

I haven't changed anything (pther than a cheap PSU for what I understood to be considerably more stable) and its doing my head in.

Any ideas?

Ok,

I've run P95 again a couple of times and now I've got failures on 3 cores after 3 or 4 minutes! It doesn't even get far enough to BSOD!! LOL!

I surely shouldn't have to increase vcore and maybe even NB volts just because I changed the PSU? It's the first time I've changed a PSU so I'm in the dark on this one.

Any help would be greatly appreciated.

Anyone?

what are your voltages anyway?

it could be possible the powersupply is not powerfull enough or its fualty, or something on that nature what is the new and old powersupply?

run it at stock and prime it

cheers for the replies guys. At AMG: the old psu was an oryxx Titan 800w one that I bought off a well known auction site for about £35. The new(er) me a a thermaltake toughpower 850w modular which I bought off a mate who was strapped for cash for £30 plus the oryxx. I'm not at my comp now so I can't give you the exact settings but I can tell you the vcore was 1.41 (I think) bios and 1.32/33 under load. CPU vtt was stock and nb was the next setting above what ever stock is (1.33 I think) forgive me if these are slightly out but their from memory(which is bad at the best of times)

@ siumatfung: I dropped it back to 3.2 and ran p95 for 1hr 20 and it was stable with no failures or BSOD's. It's only when I try to run the overclock I was previously running 24/7 that I have problems.
