I just received another S1 today and this one was used big time. Lots of Chinese dust all over the PCB boards and fan blades. Should I contact them and have them replace it?
Also might be a sign of things running out and new model coming out.
You are lucky that your S1 works.
I received heavily used and semi-dead S1 from them.
All covered in dust, heavy smell of burnt electronics, a lot of dead chips - one blade shows 8 ASICs instead of 32.
It hashes only at around 120 GH/s and sometimes just stops hashing with beeping sound, needs power cycle to start again.
I paid 130 euros customs tax for this unit, and it would cost around 200 euros to ship it back to Bitmain and then I have to pay another 130 euros to customs for the replacement unit.
Just does not worth it.
So Bitmain sold me a dead unit and now just stopped responding to my messages.
you don't pay nothing to send it back, they will pay, and they will ship you a new one, if what you told is true, u make a photo and a screenshot.
else i don't belive you at all.
they have 10000 of customers, and no one point that(one blade shows 8 ASICs instead of 32), you are the first one.
or, you didn't buy from
https://www.bitmaintech.com , and you got scamed.
My guess is that the power regulator (TPS53355) or its associated power components for the second 'segment' of the bad board died - this would result in no 1.1V signal to the chips or across the inductor, and would likely stop the communication chain to the 3rd/4th segments.
I had that happy to the first segment on one of my boards, and no chips on the entire board hashed. Bitmain took a few days to decide on what to do, and then mailed me a replacement PCB alongside my order for another antminer. I swapped the boards (the thermal paste application needed some work at the time, but seems fixed now since antminers all come with it oozing out) and mailed back my bad PCB at thier expense.
