When I specify -D 1 and -D 2, I only get 200Mh/s for each. I believe that the 1 and 2 for my devices refer to each of the two cores of the first GPU, because the numbers are just too low for them to be both running. When I run aticonfig --adapter=0,1 --od-gettemperature I get different temperatures, leading me to think otherwise.
I feel that if the 2nd GPU is enabled, then there should be 4 cores running, but only two are showing up. Is the khash/s calculation of DiabloMiner accurate?
I have tried installing different driver editions, and checked my xorg.conf file to make sure it is correct, but I just cannot get the speeds to increase. Dual 6990s should be running atleast at 800Mhash/s, but mine are half of that.
Any ideas? I can post any necessary print outs from my prompts.
I ssh into my machine btw, could it be an issue with the lack of a display?
