Safe Voltages for my System?

[James1991]

I currently have my Q9450 CPU running at 3.2ghz with my fsb set to 400 (1600).

when ever i try to put it any higher it is unstable and restarts after a while . i am thinking that this is because i still have my FSB and Northbridge voltage control set to auto.

i would like to get my FSB to at least 500 (2000), does anyone have some sort of idea what voltages i would be able to set safely for my FSB and Northbridge without damaging anything?

if it helps i have my cpu at 1.22v

thanks in advance

yeah i have already read that. i have just read throught parts of it again and it didnt really help me much.

i have been trying to oc my fsb higher how that says but even if i manually set the voltages to what the program that came with my board says they are at now, and then slowly increase them it still doesnt want to run stable. not even at 420

i am just wondering what i shouldnt go past because i dont realy want it to get damaged.

Just to be safe, the highest I would go is:

Vcore: 1.34
MCH (Northbridge) 1.45
Mem: 2.1
Southbridge: 1.25

Leave the rest at auto, just keep in mind every chip has it limit. You may hit a higher front side bus by dropping your multiplier down a notch. Try these tricks and see if it helps.

I've seen 3.2 @ stock Voltages(1.23). If you want higher your going to have to give it more juice. I would increment by +.05 V and run a stability test to self check.
Anything over 1.4 is starting to get risky, but since your under water on your cpu I think it should handle 1.4 well

I have mine at 3.4GHz @ 1.36v

O also James, I wouldn't go past 1.3v on VTT/FSB Termination voltage. Happy 'clocking!

thanks people , i am going to try for a higher fsb now. (without going over those voltages)
