Nice job. Thanks for the specific miner. I seem to have a problem that no one else has really mentioned. I have an MSI Vega 56, and I have no problem getting 1860h/s for about 5 minutes... then it drops by 200h/s to 1660h/s... and is stable at about that rate. I can kill the miner, and start it back up and it does the same thing. I thought maybe it was a heat thing, but after playing with settings, I don't think so. Looks like perhaps a bug. Any thoughts? Maybe it is related to the other use who said they loose 200h/s on their first card when they have a second card. This system does have an integrated graphics card.
