My new RX 550 video card arrived yesterday. Last night I installed it in a ubuntu 14.04 machine. The latest drivers don’t really seem to install on 14.04…so upgraded to 16.04. So far so good. Installed the AMD GPU Pro drivers for 16.04. They install just fine but clinfo shows no available OpenCL platforms. After a bit of research I find there is a bug in the AMD GPU Pro drivers for ubuntu AND that bug is the RX 550. So for now the card is mining XMR using Minergate on windows 10 pro. Not happy about having to use windows to mine this card but until the next version of AMD GPU Pro it is what it is.
I went with minergate over claymore because claymore automatically takes a percentage off the top before the pool fees.
