Hello, If anyone can help me I would be very thankful.
I'm running SGminer 4.1 with the following command: sgminer.exe -k darkcoin -u x -p x -o stratum+tcp://stratum.hashhot.com:3378 --gpu-platform 0 -d 0,1,2,3,4,5 -w 256 -I 13 --lookup-gap 2 --thread-concurrency 8192,8192,8192,8192,8192,8192 --gpu-powertune -20,-20,-20,-20,-20,-20 --gpu-fan 100,100,100,100,100,100 --gpu-engine 1020,1020,1020,1020,1020,1020 --gpu-memclock 1500,1500,1500,1500,1500,1500
Each of the XFX-TDFD 280X gives ~2 Mhash/s, but I get many HW errors, 0 WU, so 0 accepted shares, and 0 rejects as well. I'm basically mining nothing.
I tried changing and playing with all of the parameters in the miner. Intensity, TC, without gpu engine/mem speeds, -w, -g, etc. So I believe there's something else other than mining parameters that is the problem. I tired googling, and there were only 2 other people with the same problem and they couldn't solve it.
My setup: 6x XFX-TDFD R9 280X, undervolted (can undervolting be the cause?) Asrock H81 Pro BTC Win 8 64 Techpowerup 13.1 drivers SGminer 4.1
Runs perfectly on Scrypt (4.2Mhash/s) and Scrypt-N (2Mhash/s.)
