Ok, I just went through all 7 pages of the Xtremesys forum thread... In short, they link pin 1 to pin 4 of the 3037, with a resistor, 680 to 720 Ohm, to increase Vdd from default 1.55, to as high as 2.0.
Some nut OC'd his pc to 236FSB, dual mem modules, synch, with a Vdd at 2.01 ...
You should see the memory scores...(Sandra RAM int: 3655 MB/s, RAM Float: 3447 MB/s)
Still, as an Epox tech pointed out, it'll affect the voltage to the AGP slot, so it's really not a good idea. As stated multiple times:
at your own risk.
Also, although everything looks fine at first, boot, get into windows, everything ok, then run a CPU loader program and boom, crash. Now everyone is scrambling to figure out the problem... [H] thinks it's the ram, XTS points at the CPU...
