Here are my instructions for boards that use the Intersil HIP6301.

KT7 series, KK266, etc:

Solder wires to Pin 7 and Pin 10 of the IC that controls the voltage to the CPU. Put a 47k trimmer (49 cents at Radio Shack part # 271-283) between Pin 10 and ground. Put a 47k trimmer between Pin 7 and ground. You can add a 1k trimmer (271-280) in series with the 47k trimmer if you would like to make it easier to fine tune the voltage. Use a spade lug or loop under a motherboard mounting screw for your ground connection. For convenience I suggest you mount the trimmers on a piece of breadboard and secure it to your motherboard tray with Velcro.

Pin 7 controls the voltage, Pin 10 controls maximum voltage threshold. Turn the trimmers to full resistance boot your PC and start VIA Hardware Monitor. Set the polling interval to 2 seconds and slowly dial up the Pin 7 trimmer until the screen blanks. Your PC will probably reboot when the screen blanks. Note the voltage and back it off a tad while the computer reboots. Then dial up the Pin 10 trimmer until your screen blanks and back it off a tad. Go back into VIA Hardware Monitor and dial the Pin 7 trimmer up to 2.3 volts. You may be able to go higher but I don’t recommend it.

Caution this will stress your cooling. Be careful or your CPU could end up a crispy critter. I also suggest buying a third hand device from Radio Shack to hold a pre-tinned wire to the IC leg while you solder. The magnifying glass on the third had will come in handy too. Get in and out fast so you don’t toast the IC. Lay off the caffeine and if you are of age, have a beer a half hour before soldering to steady your hands.

Be sure to tie your wires down to the board. A dollop of five minute epoxy works well for this. After doing several boards, I finally screwed one up. The mod went fine but I snagged the wire to Pin 10 on the end of my workbench and ripped the IC pin right off the board.
