I recently built my first mining rig, and for the processor I went with the AMD A10 7850K APU (8 GPU cores). I also bought 3 MSI 270x cards (they were on sale for the same price as the 270's) that I haven't installed yet. Before I started mining with the actual video cards, I wanted to try to see what I could get out of the APU. So far my results are not impressive.
I'm running Kubuntu 14.04, I've installed the AMD Catalyst 14.501 drivers, then I downloaded and compiled the sgiminer 5.0.1 from github sgminer-dev/sgminer.
I've gotten sgminer connected successfully to the darkcointalk mining pool. The problem as I see it though is that I'm getting ~80Kh/s, which seems to me to be remarkably low for 8 GPU cores.
My sgminer execution looks like:
I've been going through and playing with different sgminer parameters, but so far the tweaks that I've done has not led to any increase in hashrate. I'm just about ready to install these video cards and try to get some real hashrates going, but I figured before I jumped into that I'd see if anyone on here has had any luck with mining with an APU yet? Is there something I'm missing in the sgminer parameters or config that I need to look at?
Thank you all for this community, I wouldn't have gotten as far as I have without your comments and guides.
