Please help, low hashrate

[joleyswe]

Hi,

We're using 3 pcs of ATI Radeon 7950 HD and mining trough sgminer 4.1.0. Would you guys say it's normal to have a total hashrate of maximum 6MHash/s? I honestly think its low with 3 GPU cards of the same type.

The miner is running on Windows, and our settings for e.g. mining CTZ looks like this:

Code:

cd C:\Users\Miner-1\Desktop\sgminer[DRK_Q2C_QRK_MYR_FC_INK_ANI_GRS_SIC_TWE_MARU]\sgminer
sgminer -k darkcoin -o stratum+tcp://east01.us.trademybit.com:3440 -u USERNAME -p PASSWORD -X 4,4,4 -g 2,2,2 -w 256,256,256 --shaders 1792,1792,1792 --thread-concurrency 10240,10240,10240 --api-network --api-listen --api-allow W:127.0.0.1
PAUSE

Have we missed something important to maximize the total hashrate?

Thank you so much for your help!
