When I was removing the vmem mod from my 9700TX, one of the legs came off the voltage regulator IC. So I was like :banana: :banana: :banana: :banana: , where am I gonna get another 9700/9800, or more importantly, was that leg worth $170? :D

So after much fretting and a few panicked posts and PMs, I thought, why not just run it at 3.3v?
So I did it, it worked, and I decided to make this guide for people with similar problems, or people who wanna vmod, but dont have a cermet pot.
Heres how to do the mod easily in three simple steps.
Step 1:
get a inline splitter thingy and a blade connector, they're available at almost all electronics shops and automotive stores.

find a 3.3v wire on the atx connector, and close the splitter onto it. The wire doesnt need to be bared beforehand, because the splitter cuts it when you squeeze it on.

Step 2:
Now you need to put the connector onto one end of your wire. I wouldnt normally mention this step, but theres a common mistake many people make.
bare the wire:

Now, notice how there is a split on the plug where the wire goes in? Thats the side you DO NOT want to crimp onto. If you do that, its likely going to simply fall off after you crimp it. I've made that mistake before. :D

you want to crimp the other side, like in this picture:

Step 3:
Solder the other end of the wire to the voltage checkpoint, on my 9700 it happens to be here:

Then just plug the wire into the connector you put on your PSU wire, and you're set.
Make sure you have adequate ram cooling. Ramsinks are necessary at this voltage.
This should work on other cards that can handle 3.3v vmem, but I make no guarantees, I've only tested it on a 9700 series card.
I hope this helps some people who fried their voltage regulation circuits, or just want 3.3v on their vmem.
comments and suggestions welcome. :D
