1000w psu about 5 years old corsair 600t white edd case. ok heres the problem im having both cards working fine in sli mode last week but as soon as i updated to 306.02 nvidia drivers all hell broke loose ive rolled back drivers and no change only after i remove the sli bridge and reboot all is good. but i did not pay almost $400.00 for a card not to be able to run in sli mode. and another thing when i try to use another port (e.g) displayport ddvi they do not respond so im stuck using hdmi its ther only one that seems to work. any help would be appreciated. thx the nob

try to reinstall windows with good drivers, wait for a fix, or return one or both.

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?
