post the numbers on the chips on the back side of teh board
( the ones with 8 legs or more ) and the numbers of the 8 legged chip on the front side of the board next to the mosfet and caps.

once we got all the numbers you can look at the spec sheets and see what does what, from there someone with some brains can work out what u need for the vmod

yeah, what spanky said, i cant really make out them in the pics :(

basically we need to find which ones are pwm controllers and then how to modify their regulation, usually by bringing vsense closer to 0 volts so it thinks its putting out less power than it really is, so it compensates and gives the desired more V.

REALY THANKS FOR HELP :p
HERE IS OTHER CHIP just click to elarge
http://img488.imageshack.us/img488/93/palit6600gtagpscanback7iw4yp.jpg
1) 1575 POQY
2)NCP 5434 PAI517
3)PS35H 7AACTO8
4)LM393 PEED

I CAN BARRELY SEE THOSE NUMBER so mistake is possible
IN SAME CHIP I CANT EVEN READ

[DrSpanky]

from what i can find ( or not find ) none of them look like its to do with them. i would guess its one of the chips on the front of the board and what about the numbers on the chip above number 4

[makaka]

update i just check this chip NCP 5434 PAI517
and here is the voltage result
in the upper side here is the 2d and 3d voltage:
2D ---- 3D
1) 1.88 --- 2.63
2) 9.92 --- 9.78
3) 0.03 --- 0.02
4) 17.85--- 17.90
5)1.26 --- 1.49
6)1.26 --- 1.49
7)1.03 --- 1.04
8)1.42 --- 1.44
in the lower side here is the 2d and 3d voltage:
1)7.28 --- 6.97
2)6.34 -- 6.20
3)11.98 -- 11.97
4)1.03 -- 1.05
5)1.26 -- 1.49
6)1.03-- 1.04
7)1.02-- 1.04
8)1.50-- 1.51

i can see here clear the 2d and 3d voltage of the video card (2d:1.26v) (3d:1.49v)
here i need your help to volt mod the video card

i have also checked LM393 PEED
and here is the voltage result :
upper side 2d mode
12.33
6.53
3.34
3.91
lower side 2d mode
6.53
3.34
8.25
0.02

i cant see any voltage near 1.26 or 2v for the memory voltage or gpu so i dont think that this the chip for the mode but who know maybe be u :)

waiting for help thanks
