Help to connect 6 graphic cards.

[igotek]

Hello;
I have installed 6 graphic cards on Windows 7 x64. Four graphic cards work well. But the other two cards dont work. I use USB 3.0 risers with power. I couldnt figure the problem out. Does anyone has any information about it ?

the fast solution is to install Win10 in order to use more than 4 cards

Win 7 support only 4 GPU be default ... you need to "hack" the registry to able to run 6 cards. From my personal experience, with the hack I only managed to get 5 card running, the last one was not working with the Code 43 (probably the same thing you got)

If you want to resolve quickly your situation, I propose that you install Win 10.

I think you can run everything even if it's not activated with a Key.

All of the miner softwares dont work on Windows 10 x64. They was working on Windows 7 x64.

All graphic cards are ok. Only nicehash miner works. Do you have any problem like that ?

If they are the new RX 470 / 480 cards then you HAVE to use Windows 10 or Ubuntu.
