SLI mode problem

[tsmori]

I have a Gigabyte K8NXP-SLI mother board and recently purchased a second GeForce 6800GT video card. Unfortunately ZipZoomFly did not list the new product number, so instead of getting the version 2.0 card, I got a version 2.1 card.

I've tried to use them to get into SLI mode, but no dice. The machine seems to boot, but I get no video signal out of any of the 4 DVI outputs.

Is this small version difference enough to invalidate SLI mode?

If so, does anyone want to trade a version 2.1 card for a 2.0 card (or vice versa)?

(ZipZoomFly wants a 25% restocking fee, but the heck with that, I'll eBay it before I do that).

I think a bios update to make sure both cards have the same bios will solve this issue? I'm not 100% sure though...

Yep, thanks that worked. I had to update the firmware on both cards. Once they matched, everything worked without any problems.
