resistance needed to get 1.5v on x800xl

[pwnt by pat]

I don't remember off hand what the stock voltage for these cards are. My pcb is identical to this one: http://www.techpowerup.com/articles/overclocking/112

Instead of getting a pot or pencil mod, I want to fill the missing resistor spot with an smd or ceramic resistor. All I need to know is, what resistance is needed to get to 1.5vgpu. (zalman vf700-c now, water maybe)

From what I've seen with a little searching, it's 1.35

i would use a pot with a 3 pin connector, that way u can adjust the voltage and also turn the mod on or off. with a resistor ur gonna be stuck at 1 voltage.

heres how u make a mod to turn on or off, u run the timmer(pot) to the 3 pin connector with one side open the other side to grd.. that way u can turn the mod on or off.. http://www.thelab.gr/images/reviews/ic7mods/Others/Modd_32.jpg

Just use a variable resistor. Never know when you will want more voltage.

Also, another way to set up the mod, is to have the ground either connect to a fan connector, or a spade connector and then ground it out on the case. I have my 9500 set up like that, but its really starting to be a pain, and Im just going to ground everything to the card.
