Ok so another odd update the problem might be solved but only time will tell.
After stress testing at 3.4GHz for 16 hours i went back to prime 95+heaven and got a crash almost instantly. Pissed I went back to bone stock with everything on auto. Booted again tried prime95+heaven and again another crash.
So now i am thinking it must be hardware again and since i have been having problems with the memory controller i start taking out memory sticks and trying them individually. All the sticks work so i put them all back in and start the computer. I try prime95+heaven and all is good for about 10 minutes then it crashes.
I am thinking I want to kill this thing.
So now that i have had the computer apart i am thinking it might be temp related and the only thing I can think of that might be having problems at stock is my HX1000W. If any of you don't know it is an early 1000W design and is closer to to 500w units than a true 1000W.
Well as last i switch my GPU over to the second 12V rail and the crashing stops. I have had the power supply for 3? years and have folded on it with a gtx285 and i7 920 for about a year so I guess it is getting old.
I am now back at my old 4GHz setting running prime95+heaven+music and so far it is fine about 30 min in.
