I recently purchased and installed the Biostar TA990FXE motherboard with two GTX 460s and the proper SLI bridge. Since the motherboard promised SLI compatibility I went and installed the latest drivers and I still am unable to enable SLI or even see the option to toggle it for that matter. In my device manager both of the cards show up as individual devices so I am pretty sure that it isnt a problem of a faulty card. While also on the matter of the motherboard I havent been able to have the BIOS keep my settings. I enable all 4 cores on my Phenom II x4 and whenever my machine restarts it only shows that 3 cores are being used. This has been troubling me because I have correctly saved the settings when I exit setup. The BIOS version is the one I downloaded from the Biostar website that says it supports SLI function. Thanks for your time.
