Hello, I had a couple questions regarding an SLI setup. I have looked all over the web and haven't found a fix yet so I thought I'd ask here. I recently just purchased a second EVGA 660 SC so that I could have 2 graphics cards in SLI. Both cards have the same video ram, work, and my desktop registers both of them. However, when I go into the Nvidia Control Panel, I do not have the option to set them in SLI. I have looked online all day yesterday looking for a fix and nothing worked. I have some guesses, but I thought I'd ask since I'm not that experienced with computers.
1. I have an Asus Sabertooth 990FX motherboard with my first GPU in the top PCIE slot. I wanted to put my second card in the next PCIE slot with the same color, but there is a PCI slot that is elevated right below it, so it blocks my card before it is even set into the mobo. Will my graphics card have to be in that PCIE slot with the same color for SLI to be enabled?
2. I currently put my second graphics card into a different PCIE slot that is not of the same color. These slots are PCIE 2.0x16 slots. I was under the impression that I would be able to enable SLI even if the slots were different colors and that performance was the only thing affected.
3. I have downloaded GPU-Z on my desktop, and both cards are essentially the same except for the section labled bus interface. One was PCI-E 2.0 x 16 @ x16.1.1 if I remember correctly, I am not currently home and am making this post from my laptop. The other was PCI-E 2.0 x 16 @ 4 1.1. The x16 and x4 values correspond with what my mobo manual says regarding the PCI-E slots.
4. I'm not really interested in just selling my cards and getting a better single GPU. I have seen that there would generally be no problems if I was to only have a single GPU, but I know that I would want to have multiple graphics cards anyways so I wanted to get accustomed to them now.
Any information provided would be appreciated.
Setup:
AMD FX-8120 Zambezi (mobo autoclocked it near 4.0 GHz)
Asus Sabertooth 990FX R2.0
2 X 2.0GB EVGA 660 SC
2 X Corsair Vengeance 4 GB 1866
Corsair HX750 PSU
Rosewill N900PCE Wireless N Dual Band PCI Express Adapter
Seagate Momentus XT 750GB 7200 RPM Hybrid Drive
