S5 issues: Loses one board after a week. Need to restart multiple times

[LoneRangir]

A few months back,  I picked up a used S5, but it has issues.  The status page only reports temperature for one board.  Also,  one board goes offline after about a week's time of being online.  It sometimes takes a few restarts (cold power on and/or software reboots) to get the board to come back online.  It will mine full speed for another week or so, but I will then need to go through the process again.

Any insight to what may be wrong, and how I could fix either issue (temp, needs to be restarted) would be greatly appreciated.

I had a little free time over the winter break here, so I did some swapping.  I wanted to isolate which of the two boards is bad.  I think I identified which one is bad, but now I do not get a temperature reading of the good board.  I downloaded the newest firmware from Bitmain, and I can control the fan speed manually, but I would still like to know what the temperature of the board is.  Is there any way to fix or restore the temperature reading?

Bumping after moving it from 'Hardware'.

Not software wise if the problem stay with the controller. The easiest would be to have a monitoring software auto reset your S5 every X days and then if you have temp on one board, you dont really need it on the second board then.

But it can take multiple restarts (kicks in the pants) for it to mine a full rate.  I can't figure out why the one board just bugs out totally.

A lots of boards stop working altogether. You can also set mining software such as MMMonitor to restart the miner if it triggers a low hashrate warning. So it would do so repeatedly. But you will need to setup the minimum time to reboot if you dont want it to reboot it IF it just told it to reboot (since the hashrate is low when you start it).

Yes the S5 is a bit of a mystery as to why a board stops for no reason. I have found the latest Bitmain firmware to be the best.

Worth checking the PSU voltage & also experimenting with dropping the frequency slightly.

A soft reset never really helps. I have to do a full power cycle. Does the software do that? I don't think it can.

The problem he refer to is some mystery where one board drop off and generally turn back on on its own after a minute or two. You seem to have a different, more severe issue. The software does not do a power cycle now, no, it cannot and it doesn't even properly do a software reboot either.

Anyone know of a service in the US that will repair hashing boards?

I suppose sidehack might be able to give it a go, if he has the time, since i remember he said he wasn't against it. But he might be very busy with his pod development.

But in term of time and costs, it might be better off just selling it. Or keep it and trade it in for his pod project when its on.
