I recently got a used alienware aurora r3 with a i5 2500k oc to 4.5 with a gtx 560 ti and 8gb ddr3 1333mhz and ive been upgrading it to meet my needs and i changed out the 8gb ddr3 to 16gb 2x8 sticks of corsair vengance ram which underlcokcs back down to 1333mhz and i was wondering if this supports sli as i bought 2 used gtx 960's one with 2gb for 74 usd and the other for 80 usd so id assume it would only use 2gb since they are not equal in vram i cant seem to get the SLi Option in the control panel even though i have both recoginzed and both full functional i have tried to uninstall reinstall one a time 2 at a time / with / wihtout sli bridge i cant seem to get it working any help apperciated and i dont have another sli bridge which might be the problem but any suggestions would help ! thanks!
 
Solution
Are you certain the second slot is running in at least x8 mode however? The slot may be x16, but if its running in x4 mode SLI is a no go.

From photos of the R3 it looks to be a M-ATX motherboard with a single PCIE 16x slot with a 1x below it, so you cannot do SLI because the second card has no proper slot to use.

Edit: I also found photos of some with 2 PCIE slots, however without opening it up and looking it is hard to tell from random photos without motherboard you have.
