That's a first...

[3.0charlie]

The beauty of having a laptop while troubleshooting... Anyway. First, I have changed the CPU volts to 1.30 (from 1.2975) and revised the Ram volts to 2.0V (was 2.1). Then ran Orthos again for 30 minutes - no errors. Also ran 3Dmark05: no errors, 11860 points.

Not bad for a first round.

Timings: 5-5-5-15 2T, 4-22-5-9 7.8.

Voltages:
CPU core: 1.3
CPU FSB: Auto - 1.2
Mem: 2.0
SPP: Auto - 1.2
MCP: Auto - 1.5
SPP<->MCP: Auto - 1.2

I am curious now ... did you try the vc bump and vd drop together or separately?

My guess would have been that the vd drop was the solution?

I suppose the cpu could be the cultprit, but i have seen so many undervolting successes with the c2d's at stock or snall OC that i would be suprised if it was the problem. Although vdroop on the mobo could be involved too.

Yup, dropped both at the same time - vdroop can be a pain with the evga 680i - this particular copy doesn't seem too bad. 1.30V in BIOS, 1.2950 in CPUz.

I'll run some more tests this afternoon.
