Of the four firmware releases - 20181015, 20181029, 20181105, 20181116 - is there one in particular that seems to be the "best" from a high hashrate and consistency standpoint?
1105 fell over in less than 3 days. 1029 has been solid and seems to run forever: though I can't do anything about the returns dipping lower and lower...

You can try.
