Ethereum

Ubuntu 16.04 LTS
Just install either the server or desktop version

Install the AMDGPU Pro Drivers
http://support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-GPU-PRO-Linux-Beta-Driver%E2%80%93Release-Notes.aspx

after installing, restart. then if it all works, edit and add  to the line

then run

Use Genoils cpp-ethereum Miner
https://github.com/Genoil/cpp-ethereum/#building-on-ubuntu

the pool we use is ethermine, though you can use any you choose: https://ethermine.org/

If you want to have each GPU send mining rewards to different addresses, run different ethermine commands with

Red Hat Enterprise Linux
amdgpu supports it but it just hangs at boot once the gpu is installed...

maybe it would have been fixed by blacklisting the radeon module as above? in any case ubuntu is free and familiar so whatever
