Can you post sample batch file for GPU miner
Fresh 64-bit Windows miners with stratum fixes:
For GPU miner pass -t X option where X is a number of GPUs. GPU miner has to be executed from the directory where kernel directory is located.
I do not have a batch file but a command like this should work:
minerd-gpu.exe -o stratum+tcp://rlt.blockquarry.com:3039 -u pinwc4.1 -p x -t 1 -i 22
That was running on a 280X at about 1.4MH/s. It looks like you can adjust the intensity settings with the -i flag. Also with -t do not set it to 2 if you do not have that many GPU's, you will get bad shares (boooo) submitted like nonce had mentioned.
