Hey guys maybe someone can help me voltmod this baby. Im not cant solder very well, so ive decided for the pencil mod. Where do I start? I will post pics of my card if they are needed.

Did you look around for the voltmod at XS?

I know with the 9800XT, on the back of the card, there is a resistor. You have to draw a few lines with the pencil over the RESISTOR ONLY (not over the PCB), and the darker you draw it/the more you draw = higher voltage

A pic would help, also search google for 9600xt volt mods and you should find some reasults.

Pencil modding mine allowed me to pick up about 60mhz on the Core clock.

I'm not a fan of pencil modding at all, it's very innaccurate and the mod does fall off with time if you don't take care of it correctly. I'd just get a soldering iron and practice on a junk ethernet card or ram stick that you're never going to use..... soldering isn't difficult at all, it just takes practice to get a steady hand.

That said, here's the website that I used for my volt mod on my 9800 Pro.... excellent articles with lots of pictures. It includes the pencil and resistor methods of volt modding your card, so you can choose whichever one you want.

Good luck

Okay guys i'll get a pic later. So far I have found 1 good site for the pencil mod. The PCB is the same as mine, so i guess it should work. Ill probably mod the memory first, because theoretically this 2.5ns should go up to 400 Mhz without artifacts, so i guess it's a lack of voltage.

Yeah, Soldering is definately the best method. Get some thin wire, a VR, a soldering iron, and some thin solder. First thing i'd do, is take the soldering iron tip if its not too sharp and file it down to a sharp point. Then i'd tin it, and then set up a plan. What I'd do is get each VR, and place them somewhere you can access them without removing the card (the corner towards the side of your case should work well). Then I'd cut wires around the length needed to reach the single spot you need to solder to for each VR (pin 7 on the core mod, and pin 20 on the mem mod, I believe). Solder the wire to each point, and then leave them hanging around somewhere. Then i'd get two wires long enough to reach a common COM point on the PCB from the VR's position. Then i'd splice the two wires together, and then i'd solder them to a common ground point. Or what you could do is solder two wires together at the ends, solder another wire to that, and lead that wire to a COM. Then solder each wire to the corresponding VR. Done!

Then finally, I'd get two wires for each checking point, and then i'd solder them and then place them to a female 4-pin molex or somethin.

For the record, pencil mods suck. I did it on my 9600XT VDDR and could change the voltage supplied to the chips by breathing on the PCB :o

took stock voltage readings today, 1.31 for the core, and 2.93 for the memory. I will try to do the mod today, will post results later.
