It is indeed random as i hae had prime on for 7 hours again on the 4ghz OC and no problems. Now the bigger problem is WTH could be causing vista to do this ??? the solutions ive read range from bad memory modules to "craplets" to old BIOSes to drivers etc etc
Hmm, bummer. I've been running Vista x64 Ultimate with no problems. And to be sure, it is almost certainly not Vista itself, it is something you have loaded not playing well with Vista.
You mentioned memory modules...one thing you could try is to do a Prime run in safe mode...minimal software and drivers loaded. If it's the memory modules, it should still fail, yes? Of course, a failure in safe mode could still point to something in the BIOS; but you would think that a BIOS issue would be readily sniffed out by the community. Unless maybe you have a faulty component on your board, and having that feature enabled in BIOS is the trigger; so not everyone would exhibit the issue. Sounds far fetched, but many pages back there was a guy with a P6T that would not post until he unplugged one of the onboard USB connections.
