Wow, that is some OVP they have going on.

Good man for trying though! :toast:

So far a tough nut to crack.

If Mr. nVidia engineer is by chance reading these posts... congrats man. You did a really good job. Now, enough teasing and let us in on your little secret ;)

716 core / 984 memory so far on this power supply. I have a feeling the core may go higher when I get my new one.

XFX 7900 GTX 665/1630 model.

Pin22----0-----0----0------0------0-----0------0----0
pin21----1-----1----1------1------0-----0------0----0
pin30----1-----1----0------0------1-----1------0----0
pin31----1-----0----1------0------1-----0------1----0
pin32----0-----0----0------0------0-----0------0----0

To turn a 1 into a 0, connect this pin to ground (easy)
To turn a 0 into a 1, let this pin float without a connection (not so easy)
When you connect for instance pin 21 to ground, you have 1.4Volt
When you connect pin 21 plus pin 30 to ground to ground you have 1.5 Volt

1.4 is realy easy to achieve, and 1.5 Volt is also quite easy.

SF3D, that is amazing. Could you give us a little summary on how you did it? And then post it all over the web, let's tell the world how to bring those sons of b1tches down! (cuts to a bunch of guys operating telegraphs).

I simplified all the info posted in the voltmod thread.. credits to all the hard working (and persistent) talents.

EDIT: for voltmod, replacing stock heatsink strongly recommended (heat/power increase ~16% per +0.1V, ~30% per +0.2V). Also, would somebody be kind enough to provide voltage scaling results..ie highest at 1.2V, 1.3V, 1.4V, 1.5V - for most non-extreme modders, I think about 1.4V would be enough to get to GTX clocks.

EDIT: "Vgpu measure" IS NOT GROUND.

Great, this is good news.
So i'm a newb, never Vmodded... 1) this is different from Shamino's guide, no black screening? 2) connect to ground, is ground the Vgpu measure point? As i said, never Vmodded before, just trying to get this straight.

next monday i wiil receive the waterblok and i will do the 1.4v MOD and i will report if it works great or not :D
