J's Tualatin 1.45v & 1.50v->1.65v, 1.475v->1.675v Wire Trick Guide part 1 of 2
*** DO THIS AT YOUR OWN RISK - IT'LL VOID YOUR WARRANTY ***
This will work on any Tualatin core (celeron, PIII, PIII-S) with a core voltage of 1.45, 1.475 or 1.500.
So you want to raise your default (cold boot) CPU voltage?
What we're going to do here is connect VSS to VID0, and VID1 to VID2. This will make them all "0" in the following chart, with VID3 remaining "1". Note that with a 1.45 or 1.475 chip all you have to do is connect VID1 to VID2 as VID0 is already "0".
#1: SET YOUR PROCESSOR TO ITS DEFAULT SPEED AND VOLTAGE If you have the voltage set to +0.30v in BIOS you'll get +0.30v (ie: 1.95v) after the mod when you first boot up which could damage your processor.
#2: Shut down your PC and pop the hood. Ground yourself on the case. Remove the heatsink. Remove the memory if it's close to the socket.
#3: With a marker identify VSS, VID0, VID1, and VID2. Draw a line from VSS to VID0, and VID1 to VID2. I won't be offended if you look at another guide to double check the position of the holes to be marked.
#4: Use a utility knife to make a notch/trench along the lines.
