[mzutg]

Hi,


My installation is :

MB : asrock h81 pro btc r2.0
GPU : 6*gtx 1070
OS : W10 pro 64bits
nvidia driver : 384.76

I have 6 usb riser 1x to 16x, powered with sata.

I have only 1 gtx 1070 on 6 which is working, i have error : device code 43 for the 5 others.

The only working card is with a riser on the pcie x16 port and powered with pcie cable from psu ( an boot error message asked for it).

I can see 5 other in windows' device manager, but with a yellow label and device code error 43.

I used ddu to uninstall/re-install nvidia driver

i have two molex port to power pcie port ( a boot message asked for it)

my mb bois is updated
pcie gen is set to : Gen1 (i tried Gen2 too)
virtual memory is set to 16gb

Help me please

u must have latest windows 10 updates i think, and also you don't need to play in motherboard settings if you have h81 btc pro
