Gentlemen,
I have been rummaging through the forums here and all over the net for several hours to no avail. I have seen similar posts but none that completley matches my problem. I just installed a second EVGA GTX 560ti hoping to run SLI. I have installed 2 cards in another build before and have never had this problem. The option for SLI is missing in the nvidia control panel. I just has the Physx configuration. The two cards I have are IDENTICAL. They both show up in the nvidia control panel and in the device manager. They are installed correctly and firmly in the correct PCI-e x 16 slots on my computer and I have tried 3 different brand new bridges to no avail. I have uninstalled and reinstalled the nvidia drivers several times, and I have reinstalled old drivers as well, again to no avail. I have tried 285.62, 285.79, 295.73 & 296.10. I have heard something about the new Realtek LAN drivers that Windows 7 finds conflicts with the SLI capabilities and have yet to be able to locate a viable legacy driver that will work. I am running a Gigabyte GA-990XA-UD3 motherboard, yes it is SLI ready, an AMD Phenom II X6 1100T CPU, 8GB of G.Skill RipJaws RAM, using Windows 7 64bit. I need your help guys, I wanna see my GTX 560ti's perform like they are supposed to. I have built several computers and I have never seen this happen. Please HELP . Thanks ahead of time for your help.
