Can't get normal speed on one farm with miner from
http://max.1gh.com/.
There is 3 gpu there: 290x + 290x + 270x
Here is bat:
cgminer.exe --keccak --no-submit-stale -o stratum+tcp://maxpool.1gh.com:17333 -u WALLET -p x --intensity 19 --gpu-threads 1 --worksize 512,512,256 --thread-concurrency 27400,27400,21568 --auto-fan --temp-cutoff 95 --lookup-gap 2
and it showing speed like scrypt (2 Mh). Other 3 farms (with 7970 and 7990) showing normal keccak speeds (~900+ Mh).
Any ideas, bug or feature?
