I can't find ANY information on the internet about this. I have 2 EVGA GTX560Ti models, 1 of them is the 1gb variation, and the other is the 2gb variation (with slightly lower clock speeds).
Is it possible to run them in SLI? I know that wisdom dictates it should be impossible as they are not IDENTICAL models, but i'm hoping that because they are pretty much matched in every other way, it could work.
I'm not that familiar with how SLI scaling works these days, as I have not run an SLI setup since I ran two 6800's!

Excellent news. They have plenty of room for overclocking so i should be able to get them back up to speed (or slightly over). Thanks for your answer! – Oliver G – 2012-06-21T16:42:23.140
According to a forum thread at NVidia "Note: It used to be possible to enable SLI on cards with differing VRAM (EG 8800GTS 640 and 320) via the 'coolbits' mod. However, this mod will not work with newer cards or newer drivers." http://forums.nvidia.com/index.php?showtopic=172243
– Bon Gart – 2012-06-21T16:56:41.253@BonGart The official FAQ still lists CoolBits as allowing differing VRAM amounts, and my personal experience has included a GTX580 1.5GB and a GTX580 3GB working just fine in SLI. I think there was a period of time when it didn't work, but that was merely a software limit, and they improved the drivers to allow for differences.
