I'm contacting you to ask for advice.
I have 6 new S9I miners that I bought during a destocking of a mining company.
Problem is that all the cards fail one after the other!
I lost 12 cards out of 18 in 30 days.
I am running on a normal voltage setting, no overclocking.
My room is well ventilated, never below 10°C and for the moment maximum 25°C, humidity between 40 and 70%.
I have several cards that were working very well and suddenly stopped for no reason, the 63 Asics are still visible, but the temperature sensors show 0°C.
I have others that went from 63 Asics to 0 and never worked again.
Or some that show 63, then for example 22, and 39, etc... exceptionally a card shows 63 Asics again, mines for a few seconds and stops again.
I have two miners that restart in a loop as soon as the cards start to heat up, the fans go to 100% and stop mining. I have to do either a reboot or a change of settings to get it going again for a few seconds to a few minutes depending on the power limit I ask them to.
I tried with several original Bitmain software versions, but nothing better.
What could it be?
Control card problem?
Being stored for 3 years in a shed?
The components have deteriorated from not being used?
I hope you can help me.
Thanks in advance
