Here are the specs: Intel Celeron g1820, 4GB integral RAM, evga supernova 1300 g2,
(3 x Sapphire Toxic R9 280x), Window 8 (I don't know how to upgrade to 8.1 )
I'm currently running this in cg miner: --gpu-platform 0 -d 0 -w 256 -v 1 -I 13 -w 256 -g 2 --shaders 2048 --thread-concurrency 8192 --gpu-engine 1070 --gpu-memclock 1500 --gpu-powertune 20 --gpu-vddc 1.100
The issue is that they are all underperforming :'( on avg I'm producing a total of 1.7Mhs. (That's only approximately 580Khs for each card)
All the cards are running at reasonable temps of 60-68 Celsius
Please recommend further action that I should take as well as any settings that may work.
Thanks!
