Sabertooth 990FX SLI issue....

Ok so here I am again with yet another SLI issue....

So I just upgraded to the sabertooth and for some reason I expected to be able to drop on and boot into windows with all my GPU settings in tact.. Well after reinstalling the drivers I found it did not offer the SLI option. Reinstalling the drivers a 2nd time would allow the selection of SLI but once I try to enable it the drivers crash and I have to reboot/remove/reinstall just to get the non SLI drivers reinstalled. With my UD3 I had found it took a bios flash and a windows refresh to get SLI working properly, so I flashed the latest bios and reluctantly just reinstalled windows. To my surprise the exact same issue is still plaguing my system.

First question what should I try next?

Second question is SLI normally this finicky? because this is becoming enough of an issue to make me want to switch camps.

I had a similar issue with the same board (two 560's in SLi) minus the crashing. I installed windows, installed all the appropriate drivers and tried to enable SLi. For me the option wasn't even there. I tried reinstalling the video drivers and even windows to no avail. I ended up returning the board and getting a replacement Sabertooth 990FX and all is well in the SLi department.

Have you tried a BIOS flash? My board has revision 0901 and so far absolutely no issues.

Ya I tried flashing it already. Ive just decided to pick up a Gigabyte 990FX since I have water blocks for it anyways.
