Hey,

In bios, I have the vCore for the processor set @ 1.23xxx.

With the latest CPU-Z, it says the Core Voltage for my Processor is 1.184.

I turned off C1E and EIST

theres gotta be some setting i dont see that involves voltage

I'm trying to OC past 3.0Ghz, but I believe this is what's stopping me.

Now I have my voltage @ 1.26xxx.
8 x 400 = 3200

Voltage says 1.216 in CPU-Z when running Prime95.

And It never goes higher that. So i believe this is my bottleneck!

help!

It is probably Vdroop that is causing the difference between requested and actual voltage. Some motherboards have a way to turn off Vdroop, or limit it somewhat, but YMMV.

Which CPU are you using. Is 1.26v the max that motherboard can do?
 
no, motherboard can go way higher.

It's the Q6600

ill look for something regarding Vdroop
 
1.26v is still a very low setting. Try setting it to 1.3-1.325v, you should be able to easily hit 3.2GHz with some more juice.
 
I set the vcore to 1.3 in the bios.

CPU-Z showing 1.232 while running prime95.

hasn't failed yet, temps are at ~55-60 depending on core
 
I've noticed that with my own P35-DS3L, the voltage reported by CPUZ is significantly lower than that which I've set in the BIOS. And we're not talking vdrop here either, this is at idle. While this kind of deviation is to be expected to a degree with all boards it's still pretty large on the P35-DS3L.

With that being said it doesn't bother me much, I just go by what CPU-Z reports and adjust my BIOS vcore setting appropriately while keeping an eye on my temps.

For example, right now my vcore is set in the BIOS to 1.4125 and in CPU-Z at a completely idle state the core voltage reads 1.360v. Under load (Prime95 all cores) it goes down to 1.328v which is about your normal vdrop.

Maybe it's something unique to the quad cores and this board? Or maybe it's due to the fact that this board doesn't have an 8-pin EPS12V connector and only uses a 4-pin instead. *shrug*
 
It's not unique to quads, I have an E4400 (which happens to be voltage hungry) at 3ghz with the bios set at 1.5v. CPUZ shows 1.456 idle, 1.440 load. So while I don't have much load voltage drop, I have a huge inconsistency between bios and CPUZ. It's like this with whatever bios I try. I've had F6, F5, F3, and now F7, and hoping F8 will address the issue.

At stock clocks, with voltage set at 1.325, my processor's VID, voltage shows as 1.27, so the drop of ~.6 volts is there no matter what voltage.
