You can edit one card bios change subsys ID and board Id no. then copy it to the other card bios. SLI well then work. I only used two 6800 GS PCI-E cards one was PNY other PNY after market I could not get the SLI to Engage even when software says it is. Bench mark shows it was not. I bet you could use any card of same basic specs use edit program make one board look like other board?

Do you have the sli enabled in the nvidia control panel? If it is, enable sli indicator and play a game, only then you will see if your sli is working.
