Your mobo supports a maximum of 2 cards. So what Nvidia cards are you using ? Be sure to update the BIOS and the driver to the latest.

running EVGA GTX460x2 on gigabyte ga-990fxa-ud3 mobo. all bios up to date same wit all drivers. sees both cards just doesn't give enable SLI option in Nvidia control panel. Ran SLI on 8800gt's 2years ago with a giga mobo and had no issues, ever, dunno i've been trying to get to work for days. Cards in correct slots, SLI bridge fuctions, tested it on another setup. im stumped.

Is the 2 way interface for Sli set correctly ? Download GPU-Z and check all configurations and driver settings.

i don't know how to check the "2way interface" i googled and still couldn't find anything.

downloaded GPUz but could find the interface set anywhere

Extremely sorry to have complicated this. Basically , I asked you to check all the physical sli connections between the 2 cards , to check the update of the bios (whether a later update was made to fix this particular issue or a set of iisues among which this is one) , to ensure the power fulfillment by the PSU , reinstalling and updating the drivers in safe mode and checking the sli status of the cards via GPU-Z.

was a bad mobo, RMA'd now works great. thx for tips tho!

Did you get a new GA 990fxa ud3 and it worked or a new mobo, because I want AM3+ and 32GB of ram with 2 video cards.
