7600 GS Voltage mod

[ProfNuke]

Got the Geforce 7600 GS Xpertvision Palit 256MB DDR2

the card below in this link with the fan on it.

I'm searching for every good Voltage mod for my card :beer:

yeah, thanx,....but thats exactly my problem. i found some (different) links and got a collected a 50 page long 7600GS mod Word Document. But I don`t know which one to apply :( maybe somebody can help me out with that problem :bang head

i'd compare and find which one looks like your card with the same chips and resistor values in the same places, and take a stab at that one. just make sure the vreg chips are the same ones tho.

hehe, no one is looking exactly the same :beer:

Here's (http://www.crazypc.ro/forum/showthread.php?t=3853) a post of mine, describing the Vgpu and Vmem mods on the Gainward 7600GS. Gainward uses the same PCB design as the Palit equivalents. Unfortunately, my Gainward uses a GDDR3 PCB, while yours appears to have a DDR2 one. Still, the PWM controllers for Vgpu and Vmem should be the same and mod the same way.

Find the two RT9214 ICs on you card (usualy found on the back of the card) and solder on each of them a 50 KOhm multiturn VR between pins 3 and 7 (pin 1 is in the one corner marked with a dimple on the IC). Before soldering, make sure to set the VR to max resistance. Lower the resistance to increase the voltage. Measurement points for both Vgpu and Vmem should be on the back of the card, on the row of cap legs (I see a lot of them allinged near the GPU cooler).

To make this easier, post a detailed picture of the back of you card and I will gladly assist you. :)

thank you varzpot. i will try it within the next days.

[ProfNuke]

so, here is MY card. so, now it should be a bit more easily to tell what to do on my card :)

i hope the picture has enough quality; if not, please tell me.

I got an email :"reply to post ....." and the message in there was:
-----------------------------------------
"I thinks I've got it. :)

Look at the below pic and tell me if you have any questions.

IF THERE ARE DIFFERENCES IN MEASUREMENTS, MARKINGS AND SUCH FROM WHAT I'VE DESCRIBED IN THE PIC, AVOID MODDING!

I hope you understand this will lose your card's warranty and that there is a great risk of damaging it in the process."
-----------------------------------------
but in this thread here, i couldn`t find it. so there could be two reasons for this:
reason one: the user who wrote this has deleted his post
reason two: there is an error in database so i can`t see it.
!?

[varzpot]

I've deleted the post. The attached picture with the mods looked horrible... I'll post a new (clear) one as soon as I get a chance. :)

here the ICs codes first. the voltages will follow

[ProfNuke]

so, here some meassurements:

im trying to volt mod a PNY 7600 gs.. and i was able to find the ram control circuit , was 16k and i put a variable pot on it and was able to change the voltage in real time with my dmm hooked up , was pretty neat actually.. anyway.. the only other power regulation circuit i could find (hoping to be the gpu) , i couldn't find any similar resistances. 15-18k

your pic , that 20k is the 2v for the memory im guessing.

if anyone is interested in this i can get some pics up ??
