I am performing what I will call my first knowledgeable overclock on my e6600. So far I am at 395 X 9 giving me a core speed of 3.55 GHZ I am still testing for stability right now.

BIOS SETTINGS
Vcore = 1.54
FSB = +.2
MCH = +.2
Memory +.2

Memory timings have been relaxed to 5-5-5-15 although with the memory only running at 790mhz, I should have no problem bumping it back to 4-4-4-12 after I find my stable overclock.

Temps under TAT using Prime95 for stress
core 0 = 62
core 1 = 59

Now I know that voltage on the vcore is high, but in CPU-z I am getting a reading of only 1.46 - 1.47

First of all, can CPU-z be trusted to give correct voltage readings?

Second, am was reading about pencil mods. Can one be done on the GA-965P-DS3? will this help to keep voltage the same from the bios setting to the actual output? If it can be, does anyone have a link with a tutoroial or pictures on how to do it?

I was at 1.53v and it was stable for 2.5 hours. I bumped up the voltage another +.00625 and it just memory dumped at about the two hour mark while the previous crash was due to a rounding error and I was able to shut down the computer properly. Why the sudden hard crash I wonder? I plan to stop the voltage increases at 1.55v

I was hoping to reach 3.6 - 3.8 but that looks like it might not happen. Any suggestions you have will be helpful. right now i am trying to reach the maximum possible stable overclock and then i will back it off for efficiency.

The rest of my system should be listed in my sig. for cooling, I am using the thermalright ultra 120 extreme with a scythe s-flex fan at 63cfm.
 
By the way awesome overclocking i have my e6600 set at 3.4Ghz @ 1.35v and when i run orthos @ priority 9 it generate a heat of 70c wich is nothing comparing to your overclock.
about the Cpu-z thing it isn't always right even me some time gives me less than i set it to so try other programs like everest or even your MOBO Hardware monitor if you have it but don't worry about it so much but the most important thing is that you disable all your power saving settings because some time they cause more Voltage drop.


By the way don't try to set your CPU clock higher than this under air cooling which you are using now

and at last i think that 4Ghz is the that people got with e6600

that all the info i can interest you with

i hope other guys will post here too....
 
Thanks for the mention of everest. I forgot about that program to monitor voltages. I will try it when i get home. I also noticed in the recent article on getting the e6750 to 4.1 they stated that they had the voltage to 1.5 but on the screenshot of cpuz, is showed 1.1
