If for whatever reason, you are looking for the newest video card you can get for the old PCI slot, this is probably it. Mine was clocked at 567MHz core, 333MHz memory (64-bit). The part numbers on the memory chips indicated that they were PC2-6400. Using RivaTuner, I was able to raise the memory clock to the rated 400MHz (or beyond). Of course, performance is limited by the PCI bus. My 3Dmark2001 score was around 9000. The fan noise and heat produced by the GPU were higher than what I would like from a low end card like this.
