I am new to bitcoin mining and I bought a 890FXA-GD70, 2X5870's, sempron cpu, 4gb ram, USB Drive.
I am running Xubuntu and cgminer.
When I start it up I type ./cgminer -n and it says 1 GPU Detected.
I then run ./cgminer and get 410mh/s
Then I quit cgminer and type export DISLPAY=:0
Then when I type ./cgminer -n it says 2 GPU Detected.
Then I run cgminer and each GPU gets 200mh/s and GPU1 is 20c cooler than GPU0
It seems to me that GPU1 isn't really running even though it shows it is in cgminer.
I have done aticonfig --adapter=all --initial -f
crossfire cable not installed.
