Could use some info on good voltage settings

post #1 of 6
Thread Starter 
I overclocked my Phenom II X4 955 to 3.7Ghz, and set the voltage to 1.450 on a Biostar TA890FXE.

Should I lower or raise the voltage, or is this a good setting? I totally played it by ear.

You are only supposed to raise voltages when it becomes unstable. And it's good to only increase one notch at a time to get the lowest possible voltage. You can't just set a voltage for no reason (well you can) but that would just create more heat and degrade your chip faster if that much voltage is not needed. And 1.45v for 3.7 seems like more than normal. Most can get 3.7 on stock voltage (1.35v). I use 1.4v for 3.8ghz.

Well, any settings you'd recommend?

I realize every chip is different, but a solid recommendation would be good.

The general method is to start everything at stock. Raise clocks little by little (testing for around 15mins with prime95, linx, etc). When you get to a speed that becomes unstable, bump your vcore up until it becomes stable (increase one notch, reboot, stress test, repeat if needed). Then continue the increaisng of clocks/voltage until the temperature becomes too high. 62C before physical damage. 55C until it starts becoming very unstable. Check out the guides on Phenom II OCing.

I did some tweaking and got a stable 3.7 OC at 1.25 volts, maxing 45C.

Thanks.
