how can an IWILL KA266 be modified to run at a vcore higher than 1.85.
Thanks

welcome to the forums , and they have all kinds of mods under mb reviews on the front page but to save you the trouble I think this is what you are looking for , this one is for the kk edition but at least it will give you an idea of where to look and what to look for

As the your board uses the same chip as a KT7 ( http://www.athlonoc.com/voltagemod3.php ) I would recommend using the soldering points noted in the http://www.overclockers.com/tips445/ article but use 49 cent 47K trimmers from Radio Shack. As I stated in another thread, most of these volt mod articles are way to complex. You may also solder directly to the IC. Soldering point differences noted, you can then use my standard KT7 series volt mod instructions below. The HIP6301CB works the same way on the Iwill and the Abit.

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 each wire and ground. 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 voltage peaks. This should be about 2.1 volts. Then dial up the Pin 10 trimmer until your screen blanks and back it off a tad. Your PC will probably reboot when the screen blanks. 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. 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.
 
Thanks. I found what I needed in the first article you linked to colin. I do not have and HIP I have a sc2242 or something.
 
Sorry, my mistake. I should have read your post more carefullly and noticed your A series board. Glad you found what you needed. You can still use a 49 cent trimmer. The 100k trimmer at the Shack is part number 271-284.
