Traded my 7970XT with a set of 560Ti's with my room mate, because his motherboard doesn't do SLI and mine does. To the very best of our abilities, we have confirmed that both cards are perfectly seated and that the SLI bridge is properly connected, many times. However, I don't get the SLI option.
The two cards are not identical. One has 2GB of VRAM while the other has 1GB. But they're by the same brand at the same clock speed (or at least within 499 cycles of each other I guess). So SLI should just work.
I tried DifferentSLI (http://www.techpowerup.com/forums/showthread.php?t=158907), but it crashes with the most recent stable driver, and does not support Beta releases. With the previous stable driver, it does work, and I was able to get a performance boost (and a lot of graphical glitches, and one instance of a huge decrease in performance) in certain applications. However, the problem here is that whenever I reboot my computer, I'm 'magically' on a newer version of the driver. I tried disabling 'Nvidia Update', but I guess that isn't related.
Think I remember hearing something about a exploit in the Nvidia driver recently, so I assume 310.70 is the vulnerable one, and that it silently forces me over to 310.90 because holy shit this is bad. Though that might be my memory being dumb and confirmation bias making me put together unrelated things.
My motherboard is a 'ASRock 990FX Extreme 4' (Which is a hype ass name for a low end product), graphics card one is http://www.pointofview-online.com/showroom.php?shop_mode=product_detail&product_id=277
Graphics card two is: http://www.pointofview-online.com/default2.php?content_id=2&news_mode=detail&news_id=101
Operating system is Windows 8 Professional x86-64.
Power supply does 650W, computer has a FX-8350 which shouldn't need more than 300W tops.

Right, so what do I do with this second GPU? Leave it for PhysX? Have a spare in case this one breaks? Build a cheap system around it? Are there more things I can attempt to get SLI to work? Any help would be greatly appreciated.
Thanks in advance.
