GTX285 VGPU and OCP mod

[KingK76]

Here is the VGPU mod for nvidia GTX285 to start with, I will update the thread as soon as I have the OCP mod image done.

I will also post some more info from our Tri-SLI benchmarking at CeBIT 2009.

! IMPORTANT INFORMATION !
These mods have been tested, BUT I take no responsibility for how you use
the mods and what happens to the card. Make sure the cooling is sufficient etc.
The soldering order is crucial, make sure it's done exactly as the images show.

Mod overview:

This is how it looks when soldered to the card.


We ran 1.4V+ and no sign of OVP.

OCP will trig at some point and here is the mod for that:

Please post at what frequencies it triggers for you with what type of cooling.

I have a question about the vGPU mod. I know leg 1 and 2 must be soldered to the proper pads where the SMR was. But my question is for leg three. Do you have to solder to the spot shown or can you use any proper ground. You have it labeled as ground so I hope I can just use any proper ground because when I attempted the spot you pictured the wire kind of flipped up before I could secure it and it took off about half of the end I had it soldered to. I took readings before the screw up and it still shows the same reading it's just very difficult to attach the wire there now, not to mention I'm a little gun shy of using that SMD because it took VERY little pressure to pop half the tinned end off. My card is an XFX Black Edition and everything else seems to be of high quality, but even before I attempted that spot I had a bad feeling about the way that SMD looked. It just looked bad to begin with. Anyway I hope somebody can answer this question... It would be greatly appreciated!

Sorry to add this in but I guess I should ask before attempting step 2. The OCP mod. Is leg 3 on that also just a ground or does it have to be soldered to that specific point.

Thanks!
