Is that on windows or linux, any reason to not use 4.7 or 4.8? I thought monarch support just started at 4.7?
Do you also see messages like "sanity check, device is processing unknown work, device is missing queued job. device flushed (goes by too fast), failed to find work for queue results" in the bfgminer cmd window?
Windows, and that's because my dedicated laptop that wasn't in use was running 4.5. Last night was hard, just got in from days of travel (NY, ATL, etc) and my brain is toasty.
I'll upgrade to 4.8 tonight then take a more in-depth look. So since you have these things, please post about what you have seen, what you observe. Have you taken them apart yet? Powered them down? Stuck them out a window (mine currently is in the window blowing the hot air *out* of the house :-)
