if I try to mine the same algo, using same settings, on the same gpu, but with a different miner - no good.
Now I know that it might not be the biggest problem since I can actually mine, however sometimes I'd like to mine something not supported by gminer or just a more efficient miner. Adding to the mystery is that there are times when I do manage to get a connection with a different miner, then it works for something between a few minutes to maybe an hour, and after that the error again. Usually it takes a few hours to "reset" itself. The problem has to be at my end, but can't figure out what to look for since gminer always connects and I don't recall any changes being made to my connection/router options. Any ideas?
Sounds like maybe some setting problem , not every miner software is good with the settings that working the best for another miner software.
Back in the days when i started mining i thought the same when i was using sgminer and cgminer and got different results.
Sometimes there is still a little playing with settings and commands to getting it working stable.
