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

Make sure he fitted sli link and that his board supports sli

System specs would be helpful

Absolutely none.

As above make sure he used an SLI link and that it is plugged in properly, and has he got atleast an 800w good brand PSU?

What motherboard does he/she(ha!) have?

 

[Hayleywow]

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.

On topic:

I'd suggest you try one of your Zotac 480s in your friend's PC, see if that makes any difference, and or try both of their cards in your PC.

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

How old is the BIOS ?
Flash to a newer one.

The SLI token may be missing.
Could be it has had an early UD3r non SLI BIOS loaded in error.

Early UD3r's didn't support SLI you had to force flash them with the SLI version.
GigaByte later enabled SLI on all UD3r models.

Flashed BIOS to latest and all is working now

Thanks for your help.....
