I have a problem running miner on Ubuntu. With 7950 core 1130/mem 1575 I only get 5.5 mh/s. My settings are -

/cgminer_heavy$ cgminer --heavy --vote 1 -o stratum+tcp://hvcpool.1gh.com:5333 -u xxxxxxxxxxxxxxxx -p x -I 8 -g 1 -w 256 --no-submit-stale

Already tried changing intensity and xintensity levels with no luck.

Please help!
