Thermal performance on all models is borderline with  regular workloads and should never be let alone mining.

FTFY

Thanks for the suggestion... turns out it was some kind of windows power setting that got me. I didn't have it set to high power. Found another thread that someone had the same kind of problem and changed their monitor to sleep "never" and it was fixed. I Adjusted all the power settings and it was fixed. Getting almost 1900 full time now.

Didn't change... updated to 0.5 version also.

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.
