Hi guys, first of all sorry for my english,

I really need help im starting a rig  cpu celeron g330+4gb ddr4+biostar TB 250 btc pro+ (2 RX 580 8gb One Msi armor + Power color red devil 8 gb too) + Thermaltake gold certified 750w

I try to instal windows 10 with one gpu connected it all works fine drivers ok, when i plug my second card it wont recognize it even its on and spinning NO SHOW on device manager.

I try 2nd video card alone and it works fine drivers ok recognize

I did a clean os install again this time with both gpus connected, instal blockchain drivers  bum! it works but only shows one gpu  no info no show on device manager or gpu z.

I trie to change on bios to gen2  sometimes works sometime its sloww down a lot on user login screen and wont finish log in.

Both cards works fine separately my trouble is windows no showing both cards at the same time...

Really appreciate any info or help

Thank you all.
