Super PI XS mod fail @ stock speed/voltage

[sobol]

Hi
I've just tried 1M Super PI (Xs mod ver) on my new rig. And it is failing at default voltages/stock speed.

What is odd that i can run stable 4 threads of prime95. And while I'm priming i can run Super PI and then it doesn't crash.

You need 1.4 volts on the Nb for the PC to stabilize at stock speeds with 4 gigs ? but you run your ram highly overclocked ever thought of heat being an issue or degradation ?

If SuperPi isn't stable that is not a 100 stability sign, funny though the Prime works for hours... one of the reasons I run many benchies to test PC stability...

Oh sorry for miss leading signature. Actually what is there is what I could achieve with my previous mobo with 4 sticks. On the Asus I can clock them same with prime stable.

Now for testing new cpu(received it yesterday) i restored memory to default stock V and speed to PC5300. And Super PI is failing instantly. Its not even that it is saying there's an error in calculation. It just exiting program instantly with application error.

I think it's more Vista SuperPi related then anything else, have you tried with eg 2 dimms does superpi run then or does it crap out in the same manner ?

Its not Vista, because I've changed my mobo from MSI P35 Neo and it was working fine on the very same system.

Basically what changed is my cpu and mobo everything else is same and i can't get Super PI working at stock volt/speed cpu/mem at all.

Oh and my settings for this test looks pretty much as your template.
