Try
cgminer.
All instructions and info can be found in that thread.
Ok, think I understand cgminer a bit better, but can't get it to connect to stratum.bitcoin.cz:3333, says "no live pool" and gpus do not start.
My command line is:
cgminer -o stratum.bitcoin.cz:3333 -u [my worker id] -p {my worker wd] --shaders 1024 --intensity 17,17,17 --worksize 256,256,256 -g 1
I tried the same command line except with --scrypt flag and connection to LTC pool, all gpus fired up and pumping 275 KH/s each.
It is trying to connect via the old getwork protocol over http. try:
cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u [my worker id] -p {my worker wd] --intensity 9
For bitcoins intensities above 9 does almost nothing. but you can experiment.
(Well if you have gpu sync enabled max is 14 without 10 is max.) But did not do anything for me except destabilize my system
