Very nice @ Air;)

Did you change the delta values? All the cards I had hit power problems from ~750MHz, then died soon after

Yes, delta = o. This is second card, first died.

Hi, can't find anything about those "delta values", can you give me some information? I have a 7950GT with 2900XT zombie VRM, it runs 750 GPU with 1,4V, but I still get a blackscreen with 775MHz and 1,6V...

Geometric and shader domains run at different frequencies. You can control that with the delta value in bios, so you need to edit the bios and reflash.

ROP domain also works at the shader domain frequency. Basically the geometric delta value in bios determines what would be the difference bewteen geometric domain freq and shader/ROP.

What you set in e.g. RivaTuner is your shader/ROP, then Geometric domain clock is that X freq + delta value in MHz.

For 7900GTX normally it is 40MHz, I think, but not sure about 7950GT.

So if you hit the limit of your geometric domain, you can decrease the delta. That would allow higher ROP/shader frequency at the same geometric clock.
