Have this lovely card here - runs very cool under accelero s1 - 29°/37° idle/load @ 770/1890/1070. This card just craves for a volt mod. Anyone up to figuring one out?
Thx!

Strip it naked and take lots of high res. pics, do you own a multi-meter?

I do! Though my camera is dead atm.
But I'll try to figure smth out.
Post up pics of the back of the card when you can and im sure someone here can help
Wouldnt be surprised if Shamino already has mods mapped out

Hi guys!
I managed to lend a crappy camera from my friend and take some photos.
Here is the back of the card with some voltage measuring points which i have found out to be the vgpu and vmem measuring points:
Here is another pic of vgpu circuit and voltage ic:
Here is a pic of vmem circuit and voltage ic:
one more:
Tell me if more pics are needed and as well i can supply a higher resolution pics.
Right now i'm gonna try to mod the card's bios for more volts.
EDIT: bios vmod seems not to be working (setting 1.3V for extra and 3d modes yielded nothing).
EDIT2: fixed broken pic links

no pics showing up for me (FireFox)

dang, must find some worthy pic hosting service then. Brb.
EDIT: hosted on imageshack. can you see them now?

all good now
Cheers

The IC in pic 2 is the Core controller- please can you post up the info on it- I cant make it out in the pic.
Im not sure if you have got pics that cover the controller for the RAM voltage. It will be under the core controller, close to the other edge of the card i reckon

Gpu controller:
adp3208a
J #0751
I336086.1
KOREA
I couldnt find any data sheet for it though..
About ram ic: which one of these do you think it is?
I think in vr-zone 96gt review they mentioned something about this 51117 chip..

Well the chip on the right is a power FET, datasheet: http://pdf1.alldatasheet.com/datashe...RF7328PBF.html
The other one.... I cant make out whats on it, sorry!
CPU IC: Please can you measure the resistance from the marked pin to GND? (3rd from right on the bottom side of the IC)
Please can you also probe the components immediately around that pin and see what points its connected to (that would be easier to attach a trimmmer to)

here are the pics from vr-zone
excellent- please can you confirm that the 2 points iv marked in the picture are connected directly? (or...if they arent, which of those marger solder points does it go to)
DISCLAIMER TIME:
When this voltmod is posted, it will be untested. I will not be held responsible for any dead hardware that results from a mod gone wrong. No-one forces you to try these mods. Any mods attempted will be at the owners risk.

here is a closer pic of the gpu ic
unfortunately i can't measure the resistance between pin14 and gnd prolly because of my crappy MM - it just won't show me any value (just constant 1) up to 2000k ohm.
As you can see from this pic - the 2 red dots you marked are not connected directly on my card. vr-zone obviously has somewhat different (non-reference) pcb?

Not good. Either im wrong, or you need to hit your DMM.
If anyone else has this card and a DMM, please can they chime in?
We'll worry about the core for now- if nVs last few cards are anything to go by, the GDDR doesnt scale well with volts anyway
Just checked on VR-Zone- if the GDDR controller is a mystery to Yan, I dont feel so guilty!

Yeah i dont think 9600gt is limited by mem bandwidth anyway.
Though im confused about the different layout of traces on my card and the one in vr-zone review. Not really sure which one is the reference design now. I would bet on my (Club3D) card though.
As of the resistance between pin14 and gnd - it is prolly higher than 2mohm thats why my DMM cant measure it.

Well it could be also be my DMM - you can't ask much from 10$ hardware.
Anyways if you come up with something - i'll prolly still be here lying somewhere with my 0.5L brandy.

I think the FB pin will be along the bottom edge of the chip, but process of elimination is hardly a stylish way of hunting it down...

by googling the number I came up with a possible match. http://64.233.167.104/search?q=cache:WkX6:banana::banana::banana:Q1XUJ:www.21icsearch.com/searchpdf/download.asp%3Fid%3D137161+ADP320+data+sheet&hl=en &ct=clnk&cd=1&gl=us#8
It is a 07 not an 08 but the others from the series appear to have the same layout, maybe this is just too new to be on the list.
FB is the 6th pin from the dot on the left side as you look at the chip.
completely guessing here let K404 see it and see what he thinks.

i took another closeup shot of that side of ic:

though once again i couldnt measure the resistance between pin6 and gnd..

vGPU mod is pin #6 of ADP3208 to ground.
vMEM mod is pin #5 of "51117" to ground.
Someone please measure resistance from the marked pads to GND:

You were not supposed to see this.
4.52 kOhmvGPU mod is pin #6 of ADP3208 to ground.
vMEM mod is pin #5 of "51117" to ground.
Someone please measure resistance from the marked pads to GND:
8.5kOhm
Today i can measure resistance nicely with my DMM - i wonder if that has anything to do with French brandy i was using..
EDIT:
- Naye, i understood what i was doing different - last night i tried to measure that spot while the card was running - todays measures are when pc is turned off.
Actually - when do i have to measure - when pc is running or off?!
Omg i feel so owned.

100kΩ for vGPU between the marked point and ground.
200kΩ for vMEM between the marked point and ground.
Any volunteering guinea pigs?
You were not supposed to see this.
Im willing to do it. I'll check if i have the needed VR resistor on hand.
EDIT: Unfortunately it seems that i do not have the needed pots at my disposal (highest value i have is 47k). I will check back and confirm the mod tonight when i return from my work.
p.s. Largon - your input is largely appreciated.
