    Sorry, I wrote the first comment in french :(

    When you tried to mine with one card, the log says that the card used has 1Gb RAM ... and the DAG file is 1,4Gb, so the file can't be loaded.

    There is a project of ethminer that can only load a part of the DAG file :
    du DAG : https://forum.ethereum.org/discussion/comment/17827/

    PS : Your 1Gb card is probably the 5850.
    If you want to use another card, use the param --opencl-device 0 or --opencl-device 1 (that is what I use to mine with only one of my crossfired cards)

    this worked ethminer.exe -F http://eth-hk.dwarfpool.com:80/address/pc -G --opencl-device 1

    thanks @th00ber

    No problem :)

    have you tried the Chunk miner to be able to mine with your 5850 ?

    The chunk miner is broken, it never worked correctly (it doesn't actually submit shares), and is no longer being worked on.

    AFAIK the DAGapocolypse it was intended to prevent turned out to be a simulation error.
