Volt mod for an Iwill KK266Plus

[tripwire]

Does anyone know of a volt mod for this board? or a similar board? I posted this in the Iwill section, but its usually dead, thought maybe some of you would know.

It's the same mod as a an Abit KT7 series.

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 (271-283) 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.

If you look in the lower left of this pic, you will see the HIP6301 with two wires running from it, under the AGP slot. Pin 10 is the lower pin on the right, Pin 7 is the fourth Pin to the left of Pin 10.

Here's a close up of the same mod on a KT7A. This should make the target pins obvious.

I was wondering if I could get picture of how you positioned your pots on the breadboard. Thank you so much, I will get started on this, as soon as I get my Watercooling set-up, hopefully within a week ::knock on wood::

Boy I had to dig for this one. Here's a shot of the trimmers in my very first volt mod on a KT7. HMOverclocker walked me through this in December of 2000. I used the same trimmers and breadboard with several motherboards.

cool ****. Thats a VERY CLEAN volt mod, proly the cleanest I have seen yet. Nice job, and thank you so much for the HI-RES pics:D :D :D :D :D
