I have 2 Voodoo2 1000s. I bought one assuming it was an identical board, which it isnt. It seems, however, to be the same refrence board. Everything is laid out the same, all the 3fdx chips have the same printing. Then. the RAM is different. My old one has 12 chips on one side, while the other board has 12 RAM chips, front and back. I tried to SLI these and couldnt, is it because they are different, because they have the exact same specs, and are detected as identical boards. Im using fastvoodoo2 4.0 gold edition. My main card (in my sisters computer) is a 16 meg vanta PCI. These are both PCI also.
