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?

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.
