Anybody have this working on an EVGA X299 Dark? It "works" and allows me to enable SLI but when I run 3dMark it kicks a white screen and crashes the system hard. It recognizes all the GPUs (8x,8x,16x,8x) but the first GPU on the bus appears as card number 2...not sure if that is related. Furmark seems to run fine with all GPUs at full load.
