orbitzzz: how many cards are you trying to run rn?

Thanks for the response. Looks like i'll need to downgrade the bios since one of the first things I did was update the bios.

Can't for the life of me get this motherboard to run more than 3+ GPUs on Windows 10 64 bit. Have a total of 6 Rx 580s and 1 Rx Vega 56. Currently mining Eth with 2 of the Rx 580s and the 1 Vega 56. 

Spent the night changing the bios over to Gen 1 and Gen 2 while having 4G Encoding enabled. Still no luck. Also tried the route of adding cards individually and the most I can get to show up under Device Manager is 3 cards. Currently running 2 cards that are directly plugged directly into pci lanes while one other is on an riser. I've tested the risers and all work.

If anyone has used this mobo and had some results would GREATLY appreciate any input. Thanks. 

Anyone try this thing out yet? looks pretty interesting
