Antminer L3+ hashboard issues

[Jalapan]

Hey

i have an issue with 2 of my antminer l3+ , recently some chips start going X on miner status and then are fine when i reboot and will be fine for 10+hours before some go X again.

What could this be? i have read that poor PSU could cause it.. my psus are 1650W however then are chinese so i start to question the quality...but 2x psus same problem?

Im having a hard time beliving it would happen at the same time with 2 miners.

temps are good and below 64degrees celsius, i dont seem to lose hashpower.. not what i can see anyway..

no overclocking done either

Any tips greatly appreciated.

Is the PSU You use unbranded and looks something like this:

Or is it a dedicated server PSU/Bitmains PSU?

I have similar problems. After some time one hashboard all xxxxxx Soft reboot does not help, sometimes helped power off/on, but but usually one board will completely disappear.
My PSU is Corsair RM1000, from the wall 805W, each hashboard is on separate PCIE AWG16 cable (2x 6pin)

 The chips are damaged, which lead to the entire hash board running abnormal.

Resolution: Remove the hash board to repair.
