Problems With enabling GTX 480 SLI

[Hayleywow]

Hi Guys

I have a friend with 2 x GTX 480's, an Asus GTX 480 & Zotac GTX 480 have installed latest driver and taken them out and used driver sweeper to remove nvidia stuff, but still doesn't show the option for SLI in the nvidia control panel....

I am stumped, can you help, the only thing I can think of now is that one is Asus and the other is Zotac, would that make a difference?

Cheers

Hay

Sli bridge is in place.....

Motherboard is Gigabyte EX58-UD3R SLI (rev 1.0)

Both cards are detected in Nvidia Control Panel and Device manager.

The cards are in the first 2 PCI-E slots, as this motherboard only has 2 x PCI-E slots for GTX cards

Flashed BIOS to latest and all is working now
