512mb 7900GT vmod development thread

[bbjayo]

will the graphite stick or will it need to be redone after a while?

I think it will stick =) ... if you don't have a Y.S.Tech Delta HE Fan with 8000 UPM which blows the graphit away

A 10k Ohm variable resistor is recommended. Solder it to the point marked and to ground, for example a leg of the PCIe power (where the black cable goes to!)
To reach a higher VGPU, decrease the resistance to 600 Ohm or lower. 550 Ohm result in 1,45VGPU (my card!)

We are working on the VMem Mod. I will edit this post.

Previous measurement data:
Voltage VGPU, Resistors VGPU

So what do I need to do to vmod my Legend/Xpertvision 7900GT? Conductive Paint or Soldering? And Where exactly do I need to go from? aLVaMaN I saw your thread on vr-zone. Do I really need to solder?

Thanks

That would kill your card. Use a pencil to paint around the smd resistor or just solder a variable resistor just as I suggested above.

You see that pink arrow pointing to the small smd resistor? from there to the other end of the resistor. Concrete: Look at the Resistors. It is simply Red to blue. 626 Ohm to 0,7 Ohm (Ground).

Good Luck.

It is still there

[Drager2]

aLVaMaN Thanks...
PS: This vmod doesn`t work on 7900GS! You should use 4.7kOmph to get 1.5v on GPU. And pensil mod is wrong too. A little bit later I`ll get picture.

...as I promised:
vmem for 7900GS Palit: ~47 kOmph to 6 leg RT9214 and ground.
