d3 3.3rev setting for overclock, confusing+help

[accu]

i read the duo 2 core 101, for the part i dont understand is vMcH to 1.55v and vFSB to 1.40v. in ds3 3.3 i dont see that, but i can adjust by +.1, +.2, +.3+. is there a program for vista 64bit to read those voltage?? i have cupz, speedfan, and everest.

i tried to follow the core2duo 101 as best as i can, i have thermalright ultra 120 my temp @ idle is around 30-33c and when i tested with orthos at 100 load the temp is at 50-55c
my setting as right now, e6420 overclock to 3000MHz 8X376MHz 1.42v but in cupz or speedfan it reads as 1.392V or 1.38v and never higher than 1.40v
both vMcH and vFSB are +.1 atm. and vDimm +.3=2.1v using ocz 6400ram
ram timming 5-5-5-15 atm

it seems i have a hard time to get higher than 400MHz which gave me the blue screen of death. or wouldnt let me boot then going back to default by itself

Check out my OC'ing Guide for the DS3:

Make sure all the other stuff I mentioned is turned off, locked, etc. Use that as a starting point, I give the settings to get you stable to 3.0 ghz no problem. 3.2 is definitely possible if your RAM can take it. You might also need a northbridge cooler, the DS3 is notoriously hot and NEEDS cooling.

i got it to 3.0 ghz, my question is when do or how much vmch and vfsb do i need to oc to 3.2?? the vcore is different from people to people so i have to do my part on this.

Each situation is a bit different, but in all likelihood to get to 3.2 you should only need vMCH +0.1v and vFSB +0.1v. But you HAVE to get some good cooling on your northbridge or else that might limit you there. Most people forget about cooling the northbridge on the DS3.

If you can cool the NB, then those settings *should* get you there, assuming your RAM can take it. RAM is often a limiter, depending on the brand and chips it contains.

What NB cooler do you recommend with a ultra 120 on a ds3. I am concerned about not having enough room left on the board for a NB cooler after i install the ultra 120 and fan.

These are the choices i have selected so far

Swiftech there.

There is also the Thermaltake Extreme Spirit II...it rotates so you can find an angle that will fit if it's tight to the CPU heatsink. This is what I have:

And the Thermalright HR-05 and HR-05 SLI:

These and the Swiftech are your best bets. The Thermalright ones should have a fan though, so that's a bit of a pain. The Thermaltake and Swiftech already come with a fan, so those would be my top 2 picks for sure.
