You are only at 1.42 volts. Take that thing up to 1.55v and get your 4.0ghz. btw, what size monitor are you using. It is tiny.

Isn't that the voltage after the drop? When I'm running Prime95 on my processor, Vcore is 1.5V and the CoreTemp program will show that, but CPU-Z shows ~1.45V. As soon as the processor goes back to idle, CPU-Z shows close to 1.5V again.

man, the other day i went at it and i didn't have much luck. anyway i'm too stubborn to stop so ill keep going.

1.55 is the general consensus? how about cpu-nb?

For the person who was surprised at my relatively low operating voltages -

I'm not much chop on the general Phenom situation; I just know I was able to achieve this stable OC with an idle operating voltage of 1.424V. I'm not sure how similar AMD's vDroop is to Intel's but as far as I know this voltage I have is within tolerances AMD has for Phenom IIs. I might try a 20x multiplier but I'm not sure that will be stable.

I am ordering my Phenom ii x4 965 this week. I noticed that there is a 125w and a 140w version. It looks like the 125w is the newer version. Is one better than the other? Is the 125w better for overclocking?

Yes, the 125W is the C3 revision. As it runs cooler you will find it won't get as hot when you OC.

Hello I am new. I will attempt to benchmark and overclock with you guys. 4.0 Ghz is a breeze.

I hate taking the voltage up so much, since the temps are so adversely effected. 1.450 V right now. I noticed a lot of guys had to go past 1.5 to get 4.2 and up. If I were able to keep the temps down low enough, would I need to go so high in voltage?

1.55v cpu and 1.5v on the cpu-nb. though 1.45 is about where 2.8-3.0ghz are being called stable.

Are there any heat concerns when you start messing around with the NB? All my motherboard has are the stock heatsink fins in a few locations.

I have something for you guys to ponder.....

I'm stable at:
CPU----3.811Ghz (231x16.5) @ 1.41v (BIOS)
CPUNB--3Ghz @ 1.39v (BIOS)
HTLink--3ghz @ 1.28v (BIOS)
4G Ram-1540Mhz CL6-6-6-18-24-1T @ 2.03v (Rated for 2.0v-2.05v)
Litereally Stable in Prime95 Blend mode for over 24hurs...



I bumped the CPU Multi to x17 for 3.927Ghz and left everything else the same cause that was the only settingt hat I changed.

-So tested inSmall Ftt's first no go. One core failed withon the 1st min.
-Bumped CPU Core volts to 1.42v no go. Same thing 1 core failed within 1st min.
-Bumped CPU Core volts to 1.43v passed Small fft's for over 2hours. I Stopped it and
-Ran Blend and failed after 2hours. Must have been Vcore since 3Ghz CPUNB/HTlink Passed blend for over 24hours.
-Bumped CPU Core volts to 1.44v failed Blend after 5.5hours. Thought (okay on the right track...)
-Bumped CPU Core volts to 1.45v.... FAILS AFTER 1hr 54mins....
-Ran Blend again changing Nothing and it fails after 5mins....

So W-T-Fock is going on? This is the Second C3 PhenomII that has acted like this. Like it reaches a certain point and the volts just stop working... Like the volt curve changes all of the sudden, dramatically??????

Any suggestions or are these CPU's really that "group" of quality......... it doesn't make sense to me.... Maybe I'm missing something!?
