Anyone have a problem with acc on the 940 mine if put on auto it wont post and my bios wont recognize the chip higher then 3.7ghz

This has been reported in a number of cases. Has something to do with ACC built into the chip. You have to keep it disabled.

My chip also failed to post with ACC on. I have only been able to get 3.52 stable (220x16) 1.44 vcore. However I think that my bios doesn't fully support this chip. CPU-Z lists the specification as "AMD processor model unknown". But at 3.52, it does a sub-20 second SuperPI 1M. At least it is a step in the right direction.

My x4 940 and Biostar TFORCE TA790GX A2+ board arrived last evening and now I've got everything up and running... except for one thing

My beloved xigmatek s1283 wont fit because the fins cover the first 2 memory slots. :mad:

I can't change its orientation either. :banghead:

So I am stuck with the stock cooler (which I must say is quite nice for a stock cooler)

Shes up to 3.6ghz stable at 1.4vcore, though I think I could reduce that some.

usually when you have a lower score with a higher overclock it means the overclock is not "as" stable.

well 2.1 mhz off but close it's my ram. It appears to me these AMD chips unbottle neck the GPU just as well as Intel ( or very close I should say) and that's a big step for AMD

Looking good Tom. I'm being gentle with my chip because I just sold it. Waiting for another one to arrive. I know there are others with PII. Where are the benches guys?

Yep, but I have no idea how cold since my temp probe wasn't making good contact. Another reason I decided to take it down and try again after everything has a chance to dry out.

I think I'm going to put it under a single stage after class tomorrow and get a little more familiar with the setup.

Okay, im starting to OC my 940BE and I was wondering what is a safe voltage for around 3.6Ghz? And do you think I could get it to 4.0GHz without it crashing on air?

I'll look forward to the single stage numbers. :).
