great guide, dogie
have you encountered problems with controller saving settings?
i can save only when hashing cable is disconnected or miners are off. (i got 5 chained)
have you noticed randomly chips going off after longer operation?
soft controller rebot wake them up.
i got 39/40 thermal pads, is it normal or am i unlucky ?
can you measure hashing speed, power consumption and temperature at diffrent frequencies?
any hints on undervoltage those boards? in few months/weeks they will mine less then power bill.
I've not seen that before. By miners do you mean mining boards or Tubes (ie 5x4 mining boards?).
Chips shouldn't be dropping out, they should either be there or not. What PSU are you running? Are you absolutely sure all the screws are in good and tight?
270 and 300 results are in the OP, measured pre PSU. Its not really worth doing anything more detailed because the units are quite variable outside stock speed, whether you use 4 or 8 PCI-E, 16 or 18AWG, 20C or 40C ambients etc. The results just end up as a giant band of 'its somewhere in here' which isn't very useful. We don't know any meaningful temperatures because there are no on die (or other) probes on BE200s for cost. They're not temperature sensitive anyway, as you can see by the lack of top side heatsinks. Edit: Its worth mentioning I have these PCBs from 4 different OEMs and they all perform rather differently.
I'm sure someone will work out a pencil mod when we need it, we have all the schematics.
