Phenom II steppings and max OC 550-940 - Page 97

post #961 of 2829
I am having a lot of issues overclocking mine. I got it today, but I can't seem to get a stable setup.

Sledgehammer1990, can you include some CPU-Z screen shots of your most current overclock? Perhaps there is a setting or two that needs adjustment. Are you using AOD or the BIOS?

Good luck

Well did you try little by little? How high can you go without increasing the voltage?

That isn't you having trouble OCing. That's your chip hitting the same wall almost every Air-Cooled Phenom II is hitting. Sorry, dood, but it looks like unless oyu go water, that's your max. You are technically safe up to 1.6V though, if you really want to try to push it further.

I strongly agree with this as well.

Sledgehammer1990, did you make sure you had the basic things disabled in the BIOS such as Cool'n'Quiet or Spread Spectrum? Was all of your overclocking done through the BIOS? Obviously your chipset and memory isn't the limiting factor. You may very well be at the limit of your processor.

Good luck

Sorry to dig way back, but still updating ( have been out of town for a couple days)... so did I read that correct that your stepping has "AV" where everyone else has AC???

Was that OC tested stable?

BenBrown, are all your other system specs the same after the CPU change...?

Updating in a sec on the front page through post #772... will keep plugging away at it later, and sorry about the delay in updates... life's been busy lately.

well, i couldn't get the NB to OC at all on the A79A-S. every time i would change the NB multi to manual - no matter what number i plugged in - it would just no POST. as far as pure CPU core clocks, i'd say they were about equal. running water and keeping load temps below 45°C, i still couldn't get anything remotely stable above 3.9GHz on all 3 boards (A79A-S, M3A79-T, M4A79). also, i have found that i can throw alot of voltage at this chip on this new board and it doesn't act like it wants to die... it actually keeps going

What do you mean CPU limiting factor?

I got it to be stable for 20 minutes at 3.7GHz. I will continue testing.
