Title: 5870 cgminer help please Post by: smracer on January 07, 2012, 06:36:14 AM I am stumped.
I installed Xubuntu on a USB drive and did everything correctly. OpenCL installed, etc. cgminer gets around 400mh/s when i just use 1 5870. When I turn on both of them I get around 200mh/s each and around 50% utilization on each card. crossfire cable not hooked up. aticonfig sees both cards just fine. what am i doing wrong? Are the cards not getting enough power, not enough work? 750W power supply. sempron cpu, 4gb ram, 890fxa-gd70 mb. any ideas? Title: Re: 5870 cgminer help please Post by: S.

When I type cgminer -n it says 1 GPU detected. Then I run cgminer and I get 410Mh/s Then I quit cgminer and type export DISPLAY=:0 Then I type cgminer -n and it says 2 GPU detected Then I run cgminer again and it should 2 running but only 200Mh/s each. |
