hello im having trouble finding some fitting voltages for my q6600 @ 3.0ghz. i am currently on VCore - 1.35 DRam - 1.85 Ht - 1.4 NB - 1.4 SB - 1.5 it is fine when surfing the web and doing minor activities but when playing sims 3 my computer will just turn off and restart. so i was just wondering what voltages would make it stable? i have tried to raise the vcore to about 1.425 but it still wont go stable. i have also tried putting all voltages to auto except the vcore, but that didnt work either. any ideas of what voltages will make it stable? thanks

Check your ram speed and timings try lowering the ram speed to see if its stable. If its stable then you may need more voltage for the ram or losen the timings.

The p5n-d motherboard has horrible vdroop for the cpu, so you may still be running at a safe voltage even if you are above the recommended settings. I'd suggest downloading cpu-z and checking how much vdroop your motherboard has.

Edit: Just found the site I looked at when I oc'ed my board. The optimal voltages for the actual motherboard are:

HT = 1.2

NB = 1.2

SB = 1.5

Try those out, and see if it can run stable.

My Q6600 doesent require any voltage changes to run at 3Ghz.
