hey guys, getting back into the computer thing.

current card is titled above. voltmod searching for the past 5 days has turned up NOTHING. v-mod, voltage modification, gpu-volt, v mod, nothing turned up a good result

the few results that did show up happened to be mis-named or a different interface

my card is a PCI-Express interface. stock core is 450, stock memory is 532 (2x266)

Right now Im sitting on 500/600, furmark on burning mode and 1280 fullscreen nets me a max 71C on the stock cooler, so I know Ill be ready when I do heatsink change and add heatsinks to the memory.


Heres some pictures of my card. the one in the picture is a duplicate and a damaged one at that, so disregard the capacitor that is missing behind the TV out connection and above the ram

I also took the time to write down all the letters/numbers on the chips I thought would help you guys help me figure this out.


I tried to make it clear, but my cellphone pictures dont help very much

here is a pink to my video card album on my photobucket

http://s244.photobucket.com/albums/g...eForce%206600/


listing of the letters and what the chips say on them


A: f PG2AB
___74ACTOB

B: <insert fancy "A" symbol> CAT75496
__________________________A48BP3

C: AMS1117
___3.3 0603

D: Infineon brand ram

E&F: APM 3055L
______WHBE7

G: RT9173A
___PL58A30K

H: KA78
___05R
____Gor <------"or" could be something else, cant make it out clearly


I: 151RA

J: weird symbol, seems like "A" with circle around it
___then D412
________BX681U

K&L : weird "A" symbol then D456
______________________BT5L2S

M: ATMEL6D4
___25F512AN
___SU22

***I think M is the BIOS, judging from the atmel in the typing on the chip

N: APM3055L
_____PHBHR




G above is the chip with 5 pins on one side and I believe the location for the voltmod to take place





For the most part, I want to add power to the memory, as I dont trust myself or see the benifits of adjusting the timings

I believe there is NO voltage table in the BIOS, as Nibuto and rivatuner cannot see any voltage.\

if there is infact a voltage in the BIOS, I dont have a floppy disc, so I would need to figure out how to flash via a thumbdrive

thanks guys!!

PS lemme know if you need anymore information. I tried to be thorough, and I will continue trying to track down this mod. Like I said, I either found it and no pictures or info was available " so and so did the mod and got X mhz....", the title was misleading and was actually an AGP car or the GT version, or simply doesnt exist

well, heres the pictures. 40 views and no respondse lol, I cant be the only one who wants to figure this out

So here they are












hopefully this will allow some more help.

without a voltmod I am currently running 551/661 (stock 450/532)

Im pushing more little tiny bit by tiny bit, but randomly it gets unstable beyond these settings

stock cooling and a new heatsink/fan and ram heatsinks are planned. currently runs 76C on load with this OC


I need to buy a multimeter, I currently do not have one.

unless someone has a freebie laying around an I pay shipping, Ill get one sometime next week for sure

thanks guys

Hmm 68 views and no responses. I dont much feel like experimenting with my card to find this out, the computer wont boot on the onboard GPU anymore and I dont have a spare card. If I experiment and accidentally mess something up, I wont have a functioning computer, and I need one.

To the right of the ic marked "B" there is a choke. Stick the in a pc and measure the voltage across it. I think that is the ic for vgpu.

The chip you marked "G" on the other hand AFAIK is for vddr, so vmem mod.

What 6600 do you have?

thanks!

anyone else? I still havent been able to afford the proper tools to come up with this voltage modifcation on my own. am I the only one ever to attempt a volt mod on a 6600 512mb PIC-e?

bump for a unique volt mod. 7900gt is out of the picture, and going back to my trusty 6600. anyone have any input? I dont have the balls to test for voltage increases on my own, but with instructions I have no problem doing the mod

Look at these pictures very carefully, is this what the layout of your card is..? 6600.
