Hi everyone! I'm not very good at understanding overclocking, or at least I'm trying to learn, but I'm new(b) at this and could use some assistance getting my PC stable.
I'm having an overclocking issue switching to W7x64Pro. I can use my settings in XP32 to achieve 3825MHz-vcore1.343, VTT1.28, CPU Ref set to .76. and pass P95 and IBT all day long. However, when I boot into W7x64 and try to stress with the 3825MHz XP32 settings, I fail Intel Burn Test v2.4 no matter what settings I have the vcore and corresponding VTT's at! It uses the settings from XP @ 3600MHz and is stable, but the 3825MHz settings from XP are not passing test on Windows 7. If I can get windows7 to boot and not BSOD(but IBT does fail) during an Intel Burn Test, P95 will close shortly after starting it.
I've tried going up through the vcores with the FSB set at 425MHz. Skipping one vcore setting a test sequence, starting at vcore 1.32500 and trying every (VTT)termination voltage -.05 of vcore, to -.12 of vcore(example; 1.34575vcore, possible VTT of 1.24[0.1057] to 1.28[0.0657]) It was a lot of testing and I have not found anything over 420MHz to be stable in W7x64Pro. Just can't get the CPU to OC stable at 3825MHz?
Any suggestions would be greatly appreciated!

@3600MHz- I know some of these volts could go lower!
An attempt @ 3825
Thanks for reading!
