What power supply are you using?   This could be it.

Or also look into https://bitmain.zendesk.com/hc/en-us/articles/203559969-My-S5-hashes-at-about-600GH-S and https://bitmain.zendesk.com/hc/en-us/articles/204875015-How-to-diagnose-S5-hashing-PCB

That screenshot has 21h run time. Did you try to power cycle it? My S5 regularly drop a board, though in my case that board drop in temp and power usage. Anyways maybe power cycle it and then post a new screenshot?

What PSU are you using you never told that?  This could cause only one depending on which one.

What brand and how many watts?

[k2laci]

IBM 2000W server PSU. There are two pieces, both tried.

you can contact Bitmain's Support in order to make sure what's the problem and how to solve it if it's possible.

That screenshot, OP, show you didnt power cycle it yet. You *really* should try that first and repost. But there is some hardware fault somewhere for sure with that 9%~ HWE

I wrote the Bitmain support. They said they send back to the board. To this it should be packed to avoid any damage?

Yes they check to make sure damaged/non working.  So they want you to pack where it's not going to get destroyed in shipping.

Were you still in warranty?  If not can I ask how much did they estimate?
