Default Where are the voltage points on a EVGA GTX 260 55nm?
I have 2 of these cards, and I am wondering if anyone is modding these yet.

The measuring points on my 9600GTs are right on top of the PCB, and I am hoping the GTX will be easy too.

The reason I am curious is because Nibitor is reading 2 different VIDs on the two cards, and I would like to see what voltage they are actually running at.

I tried google, XS forums, and vr-zone, but couldn't find anything.

Wow sweet. Of course I just realized the two PCBs are completely different too.

How can there be so many revisions of one GPU model. Geez.

Sorry CL3P20 I havent monitored this thread in a while. I will definitely post pics as soon as I can. I will also post the GPU-Z and Nibitor screenshots I have.

Okay the pic Bazmecc posted is the same as my EVGA SC model. My vanilla PCB looks completely different.

Here is what I found in Nibitor. The vanilla card has the higher VID of 1.18v. So far I have seen only a few of these. Most are 1.06-1.12v. I cannot flash the Vanilla BIOS to the SC card or vice versa.



Here are some pics of the vanilla card.





Some pics of the SC card.

Default voltage layout
Here you go: red for GPUv... blue for vMEM

Thanks man.

Any idea about the other GPU?

If you have a DMM..I would check for GPUv on points 'D512-D517' [from the first pic]. Really, you should be able to read GPUv from multiple points on the PCB...ideally, you want to pick one closest to the GPU to get a more accurate reading of what the GPU is actually receiving.
