2900xt volt mod.... ugh

FACE · #1 04-02-2010

This mod takes a lot of patience..... The read points were easy enough, but the tiny resistor joints were a PITA to get a good angle on.

I used this guide: 2900XT Vmod by Shamino

These are the completed pics.... yes, I know, who spilled their spagetti on my card..... Once I get results out of it I will mask that rat's nest with red tape...

So I need to know when I am supposed to raise the vddq voltage... What effect does vddq really have?.... if it has none I will really be pissed.

Nice, I have one of these cards I should mod as well!

Have fun! Just remember to count to 10 and just walk away.....

Instead of messing with the hot glue, I went will tiny dabs of superglue to hold down the wires so they do not get in the way of whatever cooler I put on it....

If I need to take it apart, I can just pop the pots off the backplate and go..

Hey, looks good to me Face but I'm a noob

Once the SS gets here I'll know how I did on it..... quitting smoking has my hands a little shaky, if you couldn't tell by the pics there.... had macro settings on and couldn't hold the friggin' camera still....

It was difficult not to create bridges in those tiny pockets of resistors and caps.... Maybe I should drink when I solder....

doesnt have to look pretty just work

Persivoire - "There are 2 basic areas of RAM chips. The I/O buffers, which control the data going into and out of the RAM chips, and the data storage resisters, which store the data.
Vddq is the voltage supply for the data storage registers, and Vdd is the voltage supply for the I/O buffers. "

"Vddq doesn't usually effect the overclock much, and can sometimes damage the mem. "

Dammit. I could have skipped that mod.....

I just realized that the 2900xt has voltage control available via software *doh* coulda saved myself some work ... mine sucked a fatty anyway didnt get anything out of it.

I tried the software route, but it sucked.

I think you did pretty good, considering some of the scores above you are most likely not legit....
