Prime 95

Running stress test (Blend) on Prime 95 with 4 threads. All was ok but the computer just randomly rebooted? is this ok? Temps were about 49 under load on all 4 cores

Here are the results so far:

Then it just ramdomly rebooted :confused:

A reboot is about as bad a failure as you can get with Prime95.

Keep tweaking.

So just underclock? or higher core voltage or something?

Could be any one of the CPU, PLL, VTT/FSB Term or NB voltages. Also make sure your memory is running within spec.

I think PLL voltage is set to auto in the BIOS? what PLL voltage would you recommend? the CPU is clocked at 3.4GHz with a V-Core of 1.19375V

Also heard that PLL stops jitter in the data right?

Thanks

Temps so far under stress in Prime

This look ok as well as the voltage? V-core is at 1.20000V

Temps look fine, voltage is dependant on how good your chip is, not sure what the recommended max voltage for these.
