I think, I have a kind of strange card, because honestly, I do not know what chipset it has. The BIOS itself, Everest, Rivatuner reports that the card is nVIDIA GeForce 7600GT 256MB PCI-E, BUT with DDR2 memory. I bought it from china, it apparantly has no brand. It somewhat looks like nVIDIA reference board design. I tried to unmask the pipelines with Rivatuner, but it does not work. The specifications are here:-
Hi i beleive that you have a 7300GT although the 7600 and 7300 have the same core (apparently)the (8pp, 4vp) refer to the pixel pipelines and the vertex pipelines as far as i can tell the only one that matches the spec is the 7300GT.
I could be wrong but thats my understanding of it.
