Guess I'll join.

4.0GHz

Was surprised how easy it was. Was my first time overclocking. CPU voltage is at 1.2875V.

4.0GHz, but I'm hoping to see a better balance of values.... Could someone help me out?

I disabled Vdroop, C-State, and SpeedStep in my BIOS, then put in the following settings manually:

CPU Frequency: 200MHz
Multiplier: 20x
CPU Vcore: 1.2625V
DIMM Voltage: 1.50V

Then under Memory Configurations I set the frequency to 1067 (2:8; FSB: DRAM) so that it would shoot for 1600MHz, then manually changed the timings to 9-9-9-24 since for some reason it changed the settings to 11-11-11-29. I left the tRFC at 88 and command rate at 1T.

However, as you can see here the voltage is set to 1.27. Now that I'm running prime95, not only has my voltage shot up to 1.282, but my temps are considerably higher than I would normally expect them to be considering I'm using a H70 (after about 10 minutes of prime95 my base CPU temp is sticking around 72, peaked at 75). Now I know that 72 isn't anything to worry about, especially since prime95 is going to be utilizing my CPU a lot more than most games will, but I was hoping to shoot for at least a 4.2 OC on this setup considering I have the EVGA P55 Classified and such a superb cooler.

Any tips on how to get the VCore to work "correctly" and possibly optimize this OC a bit more? Help would be much appreciated!

Its just how the evga p55 series "without vdroop" feature works...

I have mine windows idle at 1.352v and windows load it is 1.376 which is a raise of .024v. While I like the feature to disable vdroop, I would rather have it drop .01 or so then raise.

What I did was find my stable OC voltage load, and set it to run at that idle. Meaning my cpu is stable at 1.352v load, but it drops .024v at idle and could cause stability issues so I have to over shoot it...

I don't quite get why you would want to do that. You are running more voltage @ load then you need so that you can keep a stable idle voltage. I understand why you need to overvolt it without vdroop but why not just run it with vdroop. You end up idling a little higher but then drop to low stable voltage at load. Temps at load count the most so why overvolt at load more then you need to just to keep a stable idle voltage.

Both voltages are under the 1.40 limit now, with vdrop it would be over the 1.40 range... I think its right around .075 drop from idle to load, so I would need 1.425 or so to be at 1.375 load

And right now my load voltages are in the high 50's so they are not an issue...

#%#% EVGA Why can't they just give us LLC with .01v of Vdroop. Would make things much better.

I'd probably still take the lower load voltage. I fold though and run 100% load alot so that might skew my thinking some.

I hear ya.. I would rather that option as well.. If my memory serves me correctly no 2 cpu's/boards will have the same vdroop. Not 100% on that, but I am pretty sure that even with Giga boards there was a range of different drops/raises with LLC enabled.

The only difference is this is the first time I have ever seen a voltage raise from idle to load.. Usually there is still a drop..

Hey guys just want to let you know that I get my CPU back from Intel tomorrow, 2nd day air return shipping! I won't do any overclocking until I get a new heatsink though. I'll let you know how it turns out.
