This voltmod applies to all X1800 series cards using PCB #A520031-50 without VDDCI support.

These mods are designed for users of extreme cooling solutions who need more voltage than can be set via software with ATITool for example.

What do you do here, pencil mod? If so, what type of pencil do you reccomend? Also, how much voltage does it give to the GPU?

Solder a 50K rheostat of sorts to the points depicted. That would be one hell of a long pencil mod trace.

WTF? Why would you need volt mods? That card has driver level voltage control in ATI Tool, I know this because I played with it alot when I had mine.

Go to the BUY/SELL/TRADE section on the mainpage of these forums and post a thread in there with [WTB] X1800XT 512 master card as a title and see if you get any replies there. This is actually not the best place to try to FIND a card , as its in the wrong section for it! Peolpe will be more apt to see it for what it is if you post where I said.:toast:
