Phenom 9950 Overclocking

[gOtVoltage]

Hey, if you wouldn't mind, would you edit your sig so we can see what parts you are using? If your using anything less than a 9950BE, 3.0Ghz may be the best you can get with your particular chip.. My 9850BE is pretty weak and takes way more V's than I'm comfortable with to go much over that.

Here's a SS of my settings in AOD (w/9950). Bumping up the NB(chip) voltage and the HT voltage helped stability quite a bit. I also raised the SB v's, but to be honest I'm not sure if that was really necessary, it's only one bump and things were running good so I left it alone for now..

CLICKABLE:


I'm pretty sure this chip would do a little better than this with more V's, but I'm on air and my load temps hit 60c while running Linpack...

Speaking of Linpack, you might want to use that to test your OC's rather than long Prime runs... It stress's the system much harder, but doesn't require hours of stress to your Mobo's Power section (which tends to kill boards!)...

Here's a link for the IntelBurnTest (Linpack), Thanks again to AgentGod

Hey Dave,,

Could you run any benches you like before and after Turning OFF CPU Tweak.. I think you might just want to run with no tweak..It makes minamal differance on B3 but keeps the Heat down if you choose to not run CPU Tweak..

seeing your @ 60c load on Air and the Volts arnt over 1.5v it should bring that Load to a 56-58c. Every Bit helps right

let me know what ya think.. It wont enable TLBfix on B3 ...So you wont see a decrease in performance like with TLB..It will disable Optimal power and load states for CPU and bus..
'
Your before and after benches should practically be the same from what ive been seeing so far..Im now trying to figure How high i can sqeeze my 9950 with CPU tweak off

Hey Got, I have pretty much the same results as Chicken Patty... CPU Tweak only showed improvement on my SuperPi times, and like you the temps went up quite a bit compared to the performance boost it offered.

AutoExpress (enabled) on the otherhand gave me a pretty good boost in 3D06 and didn't seem to cause any rise in CPU temps...

I'll try to run a few more benchies this weekend to see whats up, but my gut feeling tells me your right and the CPU Tweak option w/temps is better off left disabled.

yeah same here. I have not tried auto express, but CPU tweak is no good for me.


Oh and got voltage, I have gone back to overclocking only by the BIOS, since I left AOD alone, I have achieved a higher clock as you saw in my previous post.

You want to keep AUTO EXPRESS enable at all times.
Its has to do with Cache performance.

CPU tweak i like OFF.now that i know it was the High temp culprit.

Cool beans to AOD,, i like it but i find BIOS and High OC to be more stable with out it.

Dave ,, glad to help
