When rolling back or updating the drivers, did you properly uninstall the first drivers? This might be the issue as parts of nVidia's drivers that include the SLI functionality, may not have updated properly and could explain why in SLI mode, they do not properly work.

See if the issue only started when the drivers were updated, I would try other solutions first before the hassle of an RMA. I'm not sure if your board has this (some X79 and Z77 boards do) has this feature, but can you manually turn off PCIe lanes? If so, try and turn off a lane, then re-enable it, then that might resolve the issue.

If that doesn't work, try re-installing Windows 7, and fresh drivers (you can re-install as many times as you want as long as you have the same motherboard or an equivalent SKU from the manufacturer after RMA).

If you know for sure that the motherboard is at fault, then RMA but out of curiosity, what do YOU suspect the issue may be?
