that is what mine do on low power setting.
I also do 20.5 th and about 1280 watts on low which is 1280/20500 = 62 watts a th...
Yeah your numbers are what I was using as a benchmark, as I can't find published low power mode numbers. Yours have been up and running for a while, do they stay with the Freq they lock in at startup or does it cchange on an auto update type feature.
if you have 2 weak boards and total 15763 you should pull 978 watts

I wonder if DHL's 6 hours of cold hurt it...
That's what my guess was on this, the room ambient is about 20C average these are running in my basement. On Normal mode it's within spec for (TH/S), but at low power it seems to compound the issue. I am hoping they have some troubleshooting info to pass along, as I browsed the tabs I didn't see anything I could really dig into, even the API log data is pretty foreign for now; especially when it's not as simple as 100/105 chips or something.
I've fired off an email to see what I hear back. In the one to Pangolin I was sure to mention the issues I had with the delivery just to have everything covered and documented with them. Either way tonight I'll switch between the 2, this should net me 3-4 extra TH/S.
31.7 -> 20 hopefully
15.7 -> 30.5
47.4 -> 50.5
