Help!! Windows 10 only sees 5/6 gpu

[CrashShady]

I just added 3 more MSI RX570 to my Asrock BTC V 2.0 mobo, running Windows 10 Pro with AMD beta mining driver, no overclock yet. All cards, risers and slots tested independently, Windows 10 only sees 5 cards. Fresh install, ran DDU in safe mode, installed driver, ran pixel patcher, still only sees 5!!!

Update Windows 10 to version 1709. To check which version Run>winver. Update GPU driver to latest version.

After update, mount the new card one by one. Mount one card and turn on Windows see device manager and wait until it's ready then shutdown and mount the next one. Follow this step until you see all card.

Good luck!

Also, how many PSUs are you running? If you a running more than 1 PSU, make sure they are both starting up at the same time.
