Any of you are having trouble with sli on x79 platform??

I have 2xGigabyte gtx 560ti 448+asus 560ti dc2 physx and after benching with 3dmark11 have artifacts and the screen goes off. I had the same problem in Asus Rampage. Dont know if it's driver related (nvidia drivers and x79 platform, I am using 290.53), or raid card incompatibility (I have an LSI 9750 4i connected to pciexpress).

If I switch off sli, all works correctly.

Any ideas??

In regards to there is no bios available in gigabyte page for ud7, I can say that Gigabyte is working on new bios that will be available next week...
