ASUS P5G41T-M LX BIOS Voltage MODDING E6500

[Phirebird]

My BIOS does not have a VCORE adjustment option, so i cant achieve the maximum overclock for the processor on this board.

BIOS is 702 here http://www.asus.com/Motherboards/Intel_S.../#download

I know it is possible to add support for CPUs to BIOS but can currently supported CPUs have a voltage boost applied by just editing the entry for them?

Currently the E6500 is at 3.68GHz @ 1.272 (stock) voltage, and I would like the voltage to lie between 1.450v and 1.465v so that I can increase the multiplier from 10 to 10.5 or 11 to get the cpu speed to 4GHz which cant be done without a vcore boost.

Extra Details :
Dual 2GB 1600MHz XMP Dominator GT RAM @ 1480MHz
IGP is disabled but still leaking power, so the FSB can't be pushed past 368mhz*4
Ideally 400MHz should be set so the RAM runs at its recommended speed but the IGP is limiting it.

Thanks
