S9 boards no longer hashing

[krisgt30]

I recently relocated my mining farm to a new location. (19 S9s, 6 T9s). I repackaged everything in their original boxes for the haul to the new location (700 miles away). Upon setting up the farm in the new location, 2 of my s9s now occasionally fall into some sort of limp mode (hashing two of the three boards) and one stops mining altogether. I have ordered new power supplies for the two that sometimes mine on two of three boards. (All of my machines run on HP Platinum series 1200w PSUs). The power outlets of the farm are half 120v half 230v. Oddly enough, the machines acting up are the ones plugged into 230v. However, when I swap these machines over to 120v now, they still show the same symptoms. Should I purchase the bitmain power supplies and give those a shot? Kernel log data below.

some first thoughts..

Have you measured the dc voltage?

Have you tried another PSU?

Have you tried swapping a control board from a working unit and see if it starts working ok or not?

[krisgt30]

Controller swapped with a spare, same with the psus (but also hp 1200w psus), fans also changed and Ethernet cable changed. I’m stumped.

[HagssFIN]

Does firmware upgrade do any difference?

[krisgt30]

I saved the current firmware as a backup and just tried bitmains firmware from their site with no change. Very odd as nothing changed in the 24 hours it was mining. No power surge, no power outages nor brownouts. Just went to bed with it mining happily and woke up to it mining at 0 speed with no chips recognized.

[HagssFIN]

Have you tried running the miner with only one hash board connected to power and data at time?

Go through all three boards, one by one.

You could this way find out if it is one of the hash boards causing all this trouble.

[krisgt30]

Will give it a shot and report back. Thanks.

Also forgot to mention. The voltage does vary by a couple of volts from outlet to outlet. In this specific region of the us, the 110 outlets read in the 120-130 range. The 220 read the n the 220-230 range.
