Hey guys,

First time poster on this forum with an issue. I have 2x GTX560ti in an Extreme6 running latest UEFI. I have no issues with 1 card, 2 cards in SLI run fine other than during POST. I get nothing but a black screen all the up until the Windows loading screen. So basically i see no POST info at all. I can enter UEFI, the screen is just black. I know this because I can spam delete, windows doesnt load, but if i wait a few minutes and hit F10 + Enter to save and restart it will do it.

Any theories on why this is happening? I know the cards are fine. I know the bridge is fine. Again... only happens with SLI

Thanks in advance.
