Hello!

Cold greetings from Sweden, it's winter here now :D

I would like to have a guide on how to voltmod my core and memory on my card....i'm gonna use watercooling on the core and cooling on the memory...please help me now... the default V on the core is 1.64 that's all i know, and this:

1.92v=620 ohm resistor
1.88v=680 ohm
1.84v=1k


Help me now!

Thanks!

check data sheets for ur chips who regulate gpu and mem voltage
i bet the card got the same layout like the ti4600 cards. so maccis
howto will help you...(propably)

The chip for the GPU-voltage is the SC1175CSW as mentioned in this article - http://www.xbitlabs.com/video/visiontek-gf4ti4400/ ....but i don't now the mem-chip....anybody?

the core voltage chip is SC1175CSW not the memory, did you mix them up?

SC1102CS
0218
G28105

this number stood at the other chip.....is this the mem-chip?

read the memmod on this site: http://www.xbitlabs.com/video/visiontek-gf4ti4400/


there they do it in two "steps" read it and you'll see....i'll be back tomorrow! godnight.......

yea i know i made my leadtek vmod the same way but with pots
not fix resistors..

ok....now i'm gonna give this information to my budy who's gonna do some nice mods for me ;) i'm gonna usa pots too, I think....

how much do you guys think i can reach with watercooling and aproximately 1.92 V?? Or can I use 2V???

Visual

well 1.9 is the max many peeps recommend i wouldnt add 2v or it gets propably unstable or u :flame: your chip
1.9v gpu and 3.5v mem is the max i would do with water cooling :D

Oki, then i'll go 1.92 and 3.51 then......but at http://www.xbitlabs.com/video/visiontek-gf4ti4400/


it's seems such a difficult solution at the memmod...the do it in 2 steps...

did you do that with your Leadtek? pictures, explanation?

check my leadtek thread here thats what i did... i cant follow u exactly what u mean with 2 steps etc u have solder a fix resistor
or potentiometer(5Kohm) on those chips then to gnd thats all u have todo..

they use a diode to connect the bridges? i'm lost when they start talking about that!

yea i saw that diode but erm.. im not english and i dont understand exactly what it does..first time i saw this bridge diode mod

OK, but they say in the guide, that you have to do that thing with the silicon diode, otherwise the voltage won't go up......

i hope my dad has those diodes home..or else I will have to buy one...he fixed tv's.....I guess they should be strong enough to handle the powerstrength that's gonna go through them at the card later......
