No problem with the GPUS, they all work, they all show, they're all functioning.
The problem is more in the fact that I can't run 8 miners at a time. I think this may be a RAM issue, but pretty sure it isn't as only 1.4gb RAM is taken up at most (task manager).
I've tried a few combinations - 8gpus, 7gpus + 1cpu Miner, 7 poclbm + 1 pheonix
All that needs to be noted is that, no matter what order the miners are started, the last miner to be started will hang with "miner started." It will never connect and start mining. If the last miner happens to be openCL, I will get a "poclbm.exe has stopped responding" windows message.
I did want to try Ubuntu, but it seems very tricky starting everything up with all those sudo commands. Is this a limitation within "conhost" or Guiminer?
