hello everyone,

i just bought powercolor 6970 card and when I start mining with stock clocks (940/1425) i can get max 350 hases/sec.

This is how my .bat file looks like:

setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --gpu-platform 0 --scrypt -o stratum+tcp://pool -u user -p pass -I 13 --thread-concurrency 14336

In catalyst 13.9 I can lower or raise core clock and only raise mem clock. I read that many people use concurrency 8000 but cgminer 3.1.0 wont even start on every value except 14336

i tried setting core 850 and mem 1465 and i get around 450hashes/s but I get only rejects.

What am I doing wrong? anyone with the same card from the same manufacturer please share your config.

Also to mention that computer has 4gb ram and q8400 processor on which i was able to mine with 7950 card at 665 hashes/sec.

PLEASE HELP!

thanks in advance

I had nearly the same issue, do a driver sweep with AMD's tool and update to appropriate APP SDK and Catalyst package.
