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.x
drivers are better than16.x
'sThermal 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.
