I probably missed the information somewhere  in the last 30 pages but how do you run an instance of the miner for each card?

Please run it without parameters for a brief usage help. Generally, you have to create several bat-files appending platform-device pairs to the commandline like this:

miner1.bat

Code: [Select]

mmc-miner.exe YOUR-MMC-ADDRESS 0-0

miner2.bat

Code: [Select]

mmc-miner.exe YOUR-MMC-ADDRESS 0-1


Thanks you I'll give it a try tonight

Hi,
I'm  GPU Mining  using 3 R9 280x, with HPM around 80-90hpm so that's all good.
However, after adding a 4th card in my rig(the same type) , only 3 cards are mining. One always stays idle.
At first the 4 cards are succesfully recognized but there's always only 3 workers accepting tasks.
If i try mining other coins(FTC), all 4 cards are active.

Is there a specific config to do to have the 4 cards mining?
