guys i just received a defective D3 unit, will bitmain pay for the return shipping costs?? there return process seems poor
Definitely try inspecting whats wrong first, you dont want to send the whole device, it will cost a lot, depending where are you located.
I am in the UK mate- the top hashboard is loosing its performance and throwing X instead of O its dropping to around 13Ghz. from 19.3
Sounds like Heat Hombre. These D3's are hot runnin bastards and they DON'T like running over 70c. Reset it and run your fans at 100%. I honestly think they are way hotter than S9's. A misfiring hash board, HW errors and xxxx's id very symptomatic of 70 plus c in the chips.
She is running at low 60's across all chips

im at 100% and it's in a very cool enviroment, so i am lost

That being said, she is sitting back at 19 for over 4 hours now !
