[Help]S9 hashing power droping to 0ths or 8 ths

[pupok]

hello one of my antminers S9 (13ths) is droping its hashing power to 0 sometimes to 8.. if i unplug and plug it back in it start to work without problem making me thinking its a software related

all hashing boards show 8 sets of 00000000 (none of them have Xs)

i updated it with the lastest firmware "Antminer-S9-all-201704280713-autofreq-user-Update2UBI-NF.tar"

but still having problems.. what else can i do ?

Note: one of the hashing board is showing 2k+ HW errors

note2: whenever i have to replug the antminer it start from like 30ths and then slowly go back to 13 ths

note3: i noticed that when the antminer start to get problems.. my air conditioner turn off.. it may be a electricity problem.. but i disconnected one of my others S9 and plug the one with problem in its place.. still have the problem.. its like this one S9 is draining alot more power and making my other electric machines to have problem aswell

I'm guessing that one of your S9s board aren't working anymore,
you have to send it back for repair

Seems to happen in 10-20% of them. Might be heat related, as it seems to happen more often when the intake air temp is higher. You don't have to do a hard powercycle to bring the board back up, just go to the mining configuration tab and hit the save & apply button. It will do its frequency self-test and start hashing again in a few mins.
