What amd catalyst version is everybody using for LINUX?
I find that 15.12 results in very low hashrates about 60-70% of what I get in Windows.
I'm running Ubuntu Mate 15.10 with fglrx-15.302 (which should be 15.12) on 2 rigs and not noticing maybe 1mh drop on v5.0 dual mining. But temps do go up by 4-5 degrees. I also have 1 windows rig.
