Hitman1985, is this your 7750 Kuma that we are talking about? Does the processor show up correctly in cpu-z?

How much have you applied? Did you try dropping the NB multiplier to see if the speed reduction helps with the processor overclock?

In regards to your voltage drop question, did you check "VDDA" to see if it's at AUTO?

Good luck
My NB volts is stock with this overclock and is stable as a rock... I dont seem to have any trouble pushing the NB. When I tried for 3.6GHz, I had the NB and HT at 1800MHz. It just seems this chip was volt to go any higher and if there is something limiting me, I have not found what yet.

VDDA is auto, I tried playing with it a little while ago, but didn't help any...

Quess I'll try the latest bios later tonight, going to reseat my heatsink also just to have the little extra garentee that it is seated good and have right amount of TIM.

Woohoo, got my temps lower Reseated heatsink and now doing push/pull I got my idle down to about 32C, P95 load to 46C

I'll try once more for 3.6GHz, with much cooler temps, I may get lucky...

Edit: Temps were at 3.4GHz 1.375V, before the reseat, it was about 37/52C idle/load.

Edit: Well, I just tried clocking each core seperately and the 3rd and 4th core is where all the trouble is at. I could get 3.8GHz from the first two cores stable (or close to it) at 1.4V. ACC don't help any either

Gen, try giving your NB Frequency some more voltage and see if that helps. With anything over 2400Mhz I recommend bumping it up +.200. 2600Mhz is up there and probably close to it's limit. The most I have ever seen was 2800Mhz (HondaGuy).

In regards to VDDA, try setting it to 2.5 or 2.6 to see if that handles the droop in voltage during load.

Good luck

Have already tried all of that, even tried 1800MHz for the NB at stock and a little extra voltage, it looks like them two cores are duds

I disabled the 3rd and 4th core and almost booted to Windows at 4GHz. I did get 3.8GHz stable or very close to stable (little over an hour P95) with just the first two cores enabled at 1.45V...

Gen, well not necessarily. That just means those two cores aren't capable of clocking very high. If they were duds then they would have been disabled from the beginning and you would have a dual-core processor

Well sorry to hear you weren't able to OC the 940 to your expectations. What you have now is still pretty good though.

Good luck buddy

No need to be sorry, I can get it to 3535Mhz, only 65 from 3.6GHz. Now, I was never planning on being able to get teh NB as high as I did and that alone well makes up that 65MHz

I have been extremly happy with this chip, beat my 2.7GHz 9850 hands down

Well, thanks for the help anyways everybody been fun and frustrating at the same time
