Hey there!

Anyone can tell form experience how the warranty service of bitmain exactly works? I have an S9 with a low hashrate not showing one board and one with only 2/3 of the Chips. It sucks cause I did a firmware Upgrade and it went up to almost a perfect hashrate and then dropped after another restart and two boards showed 15 degrees...which i have never seen before.

Fact remains, I would like to know if some of you know whats the fastest solution, also on payment...I prefer to pay a guy to fix that thing instead of sending it to hongkong.

Thanks for all the help already!
