AMD Phenom II X6 1055T @ 2.8 GHz
MSi 870A-G54 Mobo
8GB RAM DDR3
ATI Radeon HD 6870
Corsair Cooling Hydro Series H50

First thing, whats the current voltage for the stock cpu clock?

I would slowly increases the FSB in 5mhz steps and keep the ram bellow stock speed until the cpu maxes out. I've personally run my Phenom ii X4 @ 1.38volts for the past 6 months and haven't noticed any issues. Others have ran 1.45volts for OC and haven't had any issues. I can do 3.8ghz on 1.38 volts (C3 Phenom ii). Don't let the motherboard auto volt because the board may cook your cpu.

u can easily get 3.5ghz. thats what my 1055t is OC to. i cant seem to go higher than 3.5ghz though, always unstable on prime. mine is set at 250fsb @1.35v, NB 2000@1.25v. im using h70 cooler with 8gb gskill ddr3 on asrock 870 extreme3

I will get back to you shortly on the stock voltage of my cpu clock, but thanks for telling me NOT to let the motherboard auto volt, because that is something small that i would've had no idea so , thank you.

c_h1132: when you say NB 2000@1.25v, whats the 2000 represent?

Another helpful tip, reduce your ram multiplier to bellow factory speeds. That way, as you increase the FSB only the CPU is being overclocked and not the ram. Once you find the max CPU speed, increase the ram back near factory speeds and voltages.

I'm pretty sure he was talking about the built in northbridge (L3 cache and mem controller). On my C3 Phenom II, I can run the northbridge @ 2600mhz and 1.3 volts.
