Hey, I hope you guys can help me out. This is my first time Vmodding and I would like to know if there's anything I should know before Vmodding like the current voltages and what not.
My question is how to pencil mod my graphic card. I've seen some guides but its different on my card. I'm using Palit 7600GT 256mb card. Will upload the picture soon if needed thanks

this not same?

Yeah, I've seen that one but its not the same, mine as lots more stuff at the back.

Uploaded the pictures for your convenience
Thanks.

Can I have a close up and better pics of the areas marked in the green boxes

Voltage measurements for vgpu and vmem should be at one (or more) of the legs of the capacitors which is marked in a blue box

i can learn from this thread actually, i have a 76gt too

I have taken the spots as requested, Thanks !
Sorry for the bad quality, hope you can see it. I only have a phone camera

no problem, actually i just needed the codes on the back of the chips you toke pics of, could you tell me what is it

the next step after this involves a multimeter

Ahh...you're still awake, below is the codes you requested. Not sure if its 100% correct cause its kinda small.

I could only see the codes on 2 of the big chips which is

APW7055
MJ101

744CT08D
BB980 03
Un60635E

I also checked the small ones if you need them

WV3

103
102
512
222

Thanks ! btw my motherboard has a feature to increase the voltage, is it dangerous? it said it will lower my cards life span, is the volt mod related to this?

The motherboard voltage increase affects the CPu, chipset and rams, it does not affect the gpu in anyway, unless you zap up PCIE voltages, according to the codes given, i found this data sheet and this is my results, could you please double check the IC stamping of the below two IC's please? Use a magnifying glass if you have too





please check if blue spots are connected directly to the blue leg marked, and is the green spots grounded?, and measure resistance of the blue leg marked

Thanks ! but could you please clarify to me the term IC, is it the code on the big black thing? Sorry i'm new to this.
How do I check if the blue spots are connected to the leg? and the green spots grounded? They all don't look connected to me.
Thanks. . Oh and about the voltage settings found in my motherboard, its AGP voltage.

ic is integrated circuit, the black color chips with a bunch of legs

for measuring, u need a multimeter....

aww i don't have a multimeter, is there any other way? How much is one?
Thanks.

i thought u have.... anyway, go get one, its like rm 20~50 only

wow, trying vMOD without a multimeter... basically same as going battle without bringing guns...

btw, voltmodding a 7600gt wont bring much effect, at least to new games. voltmod a 7900, 8800, 3850, 4800 will gain much more.

experimenting on 7600 is good choice thought

Just went out to get one =). No idea what I'm suppose to do though, hope you don't mind teaching me
Thanks alot !

Added on August 19, 2008, 4:04 pmYeah, my card is pretty old and I can't take the low fps anymore and about the AGP voltage settings in my bios, is it dangerous to increase it?

hahaha, no la, its more like... trying to cycle... without a bicycle




dont increase agp voltage, it does not increase the card's voltage however

set the multi meter dial to the green color, x10 or x1k

and go poke the green and blue spots mentioned and let me know the reading

This post has been edited by bryanyeo87: Aug 19 2008, 09:09 PM

ok i poked around the places mentioned, all the readings seems to be the maximum on the meter. I poked blue to blue and green to green according to your picture but for the second picture i can't find the second green spot for me to check.

I rechecked the numbers again and found that I made a mistake

the numbers are as stated below

APW7065
MJ101 B

74HCT08D
BB980 03
Un60635E

Left Picture small IC
either 018 or 810 i can't tell (top)
a square for the bottom

Right Picture small IC
358

Thanks alot !

ok,

for the first pic, can you measure the resisntance between green spots to the IC's blue leg?


for the second pic, the spots to be measured is marked already, could you please check

Resistance meaning the OHM?
Just read the multimeter guide checking now.

Edit: Just checked it, all seems to be maximum on the meter. Thanks

impossible to be maximum, ok, can u measure the green spots to the ic leg? or swap it to blue spots and ic leg
