B55 overclock to 4.0Ghz?

post #1 of 12
Thread Starter 
I currently own a Phenom II x4 B55 (unlocked cores) and I have it running at 3.6ghz. I've been meaning to push it up to 4.0ghz but I'm not entirely sure what I should do differently given that it's a crippled 955. What should I set my NB voltage and frequency at? CPU voltage?

Thanks in advance.

You might want to add some MOSFET heatsinks to that.... not that it's so unsafe it's going to blow, but an unlocked & overclocked x2 is over 125W, which is perhaps taking an unheatsinked 4+1 on 3-transistor design too far. During stability testing you may notice the CPU throttle down or a random shut down as part of this board's protection feature, for possibly unknown reason, until MOSFET temps (which may not be visible) go down.

Did you change any other settings beside the multiplier?

I'm running stock volts @ 3.6... I'll bump it up to 3.7 and see how it goes. Before that I'll run P95.


UPDATE:
It seems my max temp is 51c @ 3613Mhz. Running a torture test on P95. The temperatures otherwise max out @ 45-46c while playing Crysis, and I live in Florida.
So far I haven't failed any test on P95, should I test it for a little more and start pushing more? The CPU is @ 167.40W right now.
