hasnt everyone with an S2 shut it down already??

0.30USD per day is hardly worth it, is it?

no I'm running all of mine still, but what is annoying is that they take 1100w each and that is double the s5, so my actual capacity becomes limited. but they can be had super cheap. so for me it's 1 th for 150 bucks, so per th it's not a bad deal. I just loose opportunity cost.

Can also get to hashnest.com via hashne.st and minerlink.com via miner.link for short. Both are controller by me but both DNS direct to the full sites.

Agreed but maintenance fee is killer.

only what is available in the gui. I think it was 196M ? I don't have it running right now, but from what I could tell from the firmware upgrade there were three settings. The middle being default. The lowest setting had no effect. I ran it again today after doing a manual reset of it from the led panel and the same thing happens. Does the S2 run at 1000W consistently or is even my first watt meter showing 1090 too high for the miner to be at. Maybe it is the PSU, something with it. I looked at the cables and such and couldn't find anything unusual. There was some wear on the fabric covering the large on power cable, but that was from being bent. It's got to be something with the PSU or the controller firmware/board at the base and/or the beaglebone (i think that is what it is).

At this point I would think it's the psu... mine died after the 2 months and it would also run for a few minutes and shut off (I don't have a killawatt). I had it replaced by Bitmain and it's been running perfectly since.

You could try removing one or two of the boards and see how well it runs like that.... that's what I did while waiting for my replacement psu.

Its better than nothing, although it also reduces stress on controller and the backpane. Only real way to know is get another PSU to test the S2 separately.

the kill-a-watt I have is showing at 1115 Watts at the wall. Since just moving the box it has been shutting off quickly. The only other thing that I have done is update the firmware a while back and have it set at 196M and 725 Volts. I have a 18 gauge computer cable that showed some wear on one of the terminals. I ordered a 14 gauge cable to replace it. There's some dust inside, but other than that I'm not sure what is going on. Anyone have this problem. I'm close to retiring it anyway, but would still like to know if it works fine (and safe) until I shut it off completely.

What voltage and frequency were you running before? If you're getting 1115W at the wall then you're very close to maxing the PSU. (as are stock S2s though).

It's always been stock frequency and voltage. So I'm not really sure why its doing that. In addition, the watts start out at 1090 and then increase after thirty minutes to 1132. After this at some point it shuts off. I'm not an expert on electronics, but could this be something that would be caused by one, the 18 gauge power cable? Or dust in the S2? Or do you think it is the update I made to the firmware?

Did you replace the cable before you moved the box? Was it working fine with the new cable before you moved it? I'd suggest trying the old cable for an hour to eliminate that possibility.

If you see dust in the miner then there is probably more in there than you think, I'd suggest taking the boards out and cleaning them off with a damp cloth. You'll be surprised how dirty they get and what a difference it makes to the fan speed after a decent cleaning.

At this point I'm a bit stumped. I have tested it several times using the following. The old cord, a new 14awg computer cable, and compressed air cleaned the boards, moved the miner to several different outlets. The same occurs on all miner starts off around 1080 watts and climbs to 1125-30 and abrubtly shuts off. I've reset the boards, I am using the new firmware. I've rebooted it from the gui. I tried the reset button on the outside of the box and for some reason I couldn't get the button to work, not sure where that leaves me. At this point I have a seemingly functioning miner that increases watts until it exceeds the internal psu and shuts off. I have not used Kano firmware, but did mod something quite a while back to change something from (not frequency) but some other function to 1 that would reduce HW errors. However the miner has run exceptionally well for at least six months since that time. Any ideas of what it could be electrically that could cause an increase in watts from the boards?

Have you been able to underclock after booting to see if you can get it to stay up?

doubt there will be any new firmware on a unit this far out of the production cycle … "unless they come out with a upgrade" Please run the last firmware they have on their site … It has issues but its your best bet ..

The things you've suggested as causes are all reasonable, although you can probably ignore firmware for hard shutdowns. It will either be PSU load, PSU overheating or your cable overheating in some fashion.

I'd feel around the new outlet, see what it may be sharing the circuit with, you said you recently moved it, may not be playing nice with something else on the line or a hot panel breaker.
