Ubuntu 14.04, 6x Radeon Sapphire R9 390 GPU, AS Rock H81 pro btc, ETH miner
Below I'll provide a list of all of the different URLs I'm going to in order to fix this issue .
My SYSTEM:
Ubuntu 14.04
AS Rock H81 pro btc
6x Radeon Sapphire R9 390 AMD Radeon™ R9 200 Series AMD Desktop Product Family Compatibility
The Ubuntu works fine - but it can only find ONE of the 6 GPU not.
I'm trying to mine (Ethereum).
My GOOGLE search string:
(ASrock | H81 "pro btc" | "r9 390" | "r9-290" | Radeon | Sapphire | AMD | ATI | ubuntu | "pci-e" | riser) and (multiple | two | three | four | five | six | 2 | 3| 4 | 5| 6) and (mine | mining | miner)
DRIVERS PROBLEM !!!
Any assistance you could provide would be great!
I'm in China, and sometimes getting support is difficult.

Interesting section in the middle talking about how - once the GPUs are identified - to start up multiple ethminer instances
Clear but, did NOT WORK for me
However LOTS of commands at the end of the page

Go into the motherboard BIOS settings and enable multiple GPU support. And then, after you have 2+ GPU in, you will need to press 'n' (if you don't have a monitor hooked up) to get passed the warning of not having a molex plugged into the mobo (assuming you have powered risers). You will be good to go. :)
