try switching the lane speed to gen1 for x1 and x16
plug your both gpus in the slot which are nearest to the cpu and give it a try

Hi Folks,
Have spent quite a while trying to get this board http://amzn.to/2C9if24 up and running with 2 WC Vega 64s. 8gb Ram, 1000w EVGA PSU.
Had PSU and Vegas running on another MB, so know they're not DOA. I can get one Vega recognised and hashing happily, but cannot for the life of me get the second to fire up.
Lights are on, fan is spinning, there's even a light on the board that says the PCIE lane is occupied, and I can get the bios to accept another gpu is plugged in if I swap to slot 2, but then win10 won't boot.
I've tried enabling 4g, but that seems to prevent boot entirely too, and tried setting PCIE gen 1.
Basically, it'll either not boot, or only recognise one GPU.
I've also checked all cables about 4 million times, and tried several other risers in case this one has mystically died.
I know this board has issues running multiple cards, but expected it to be able to run two.
Any thoughts before I rebuild the whole thing again on a different - less crap - board? ;-)
Thanks!
