I have the Tahonga R9 380x
I am on
Ubuntu 14.04.4 LTS using the Open CL version:
15.201-0ubuntu0.14.04.1 which i got after running the
apt-cache policy flgrx command.
The drivers are not headless meaning I have to use a display to do some stuff etc. fan control
According to https://www.cryptocompare.com/mining/sapphire/radeon-r9-380x-ethereum-mining/ , I should be getting around 24 MH/s per card.
The way I see it, this could be due to the following reasons:
Drivers. The drivers are not optimal for mining. This is however countered by this guys answer that claims that
15.xdrivers are better than
Thermal throttling. Le card is throttling itself. Maybe I need to fiddle with some settings to increase thermal headroom? This is however countered by the Saphire's giant ass heatsink and the fans don't even kick in till about 40% load.
OS. The OS is the problem. Maybe I need to go a full headless setup by installing Ubuntu Server. Because what I currently use has a desktop environment, even though no display is attached since I SSH into the rig. Maybe the desktop environment is stealing some GPU hashing power?
Inputs from anyone with the same config or related would be highly appreciated.
