I have an Antminer s3+ and the miner's firmware is up to date but every 2 days the miner starts beeping, the ethernet lights completely go out, and the red light blinks and I have to power my psu down. Then if I try turning the s3 back on it, the red light still blinks and the ethernet lights that flash do not turn blink or turn on even though it is connected with an ethernet cable. This problem then goes away if I leave it off for a few days. 3-5 days later when I turn it back on it works for another 2 days and then I get the same problem over again.

Has anyone else had this problem?

Thanks in advance.

At a gross level it sounds like a thermal/temperature issue, though a "cooling off" time of days seems excessive. I assume it's possible to check S3 temps, but I've never owned one. The other possibility could a thermal issue with the power supply. What kind of PSU?

Have your tried a different pool?

Google works great.... try it ... here's the manual: https://bitmaintech.com/files/download/Antminer%20S3%20Manual_EN_2014.7.16.pdf (https://bitmaintech.com/files/download/Antminer%20S3%20Manual_EN_2014.7.16.pdf)
Several posts on the forums about this just search.
It's related to overheating above 80C or it's just loosing connection to the pool.  If it's overclocked bring it down to stock speed.  What's your ambient temp where you have it located?

And if it is hitting this 80c point you REALLY need to try to cool it down.  This is the point it will hurt your miner.

That is far to hot to run on long periods of time.  If you are not having heat issues, I would look at PSU is it a cheap psu?

I more concern about his PSU.
@beginnerMiner, i wonder what is your psu brand & type?

Thats why I mentioned psu :) Summer is starting to get hot in some places both are valid ideas.   I think between PSU or heat we will find the issue.

It well could be the psu.  If he runs too much on one rail it could overheat and shutdown causing it to lose connection to the pool, thus causing the beeps.  This happened to me.  Can you answer some of the questions these good folks are trying to help you with?  Then we can help you.

The S3 has only 12V inputs, the controller (a Beaglebone?) must be powered from that. Does anybody know which 12V connector actually supplies the current for the controller? I expect that the Ethernet lights mentioned require good power to the controller, but I don't know where the "red light" comes from. Also the controller?

Thank you guys for helping. I have a APEVIA ATX-CB700W 700W ATX12V psu. I think it may be overheating. I did switch the setting to continue running even if it exceeds a certain temperature for a small period of time. However I changed it back to the default setting which is to stop if it exceeds the temp.

truly poor quality psu.  I have a spec link let me find it.

EPS12V


115 / 230 V 50/60 Hz

each rail does 23 and 26 amps

philipma1957 is right psu is bad.  Don't buy cheapest PSU you can find your not doing yourself or your miner a favor.

I have been using RM1000's for quite a while including my S3 day's.   Used one to power two never once had a single power issue

So if I change the psu since I do have a REVOLUTION87+ 1000W psu all the problems should go away? I haven't overclocked the miner and all the other settings are default.

I personally have not used that brand of PSU.  But it's worth a shot, I would try it.

The first psu you showed was just horrible quality for mining.

That is good PSU based on jonnyguru. But it's not single rail, it's have four rail. Each rail can deliver 30A.
But the connector divided to V2, V3 & V4. Each connector have 2 x 6 pin pcie connector which can connect to one blade only. Lets say one blade use 170watt(14A), then you are wasting 16A on each rail.

Single rail PSU is the best choice.

I don't really understand the "wasting 16A on each rail". The current used  is what the miner requires, not what the PSU can supply, If the 12V load on the rail is say 15A, then that's what it gets. If you are trying to find a way to connect more mining hardware to the one power supply, then it matters. As long as a rail can supply what's need, with some margin, then you should be good to go.

Once the OP finds out if his miner will run for days at a time, without the "2-day stop" issue, then he can figure out what might be better and if he wants to spend the money. Until it's working well, it makes little sense to try and optimize the situation.

One other comment. It became obvious to me that it's usually a good idea to get a better PSU that might absolutely be required. A good PSU will likely be usable on a new generation miner. I now understand that a good PSU is a longer term investment than the actual mining hardware.

A good psu is a good choice as a investment.  You can easily use them for multiple generations like alh has mentioned.   I have some RM1000's I paid off with S3's and now its just extra being able to use them with next gen gear.

And you can always sell PSU's aswell if you wanted if high quality. So it's not a "sunk" cost.

My miner stopped running again after switching the power supply. The room the miner is in never exceeds 75 degrees fahrenheit. Anybody have an other ideas why it isn't working properly or how to fix it?

What is the PSU brand & type now?
And how is the connection configuration from PSU to miner?

I know ill get slammed for this but i used to run 3 x S3+ overclocked on 2 x Corsair RM1000's

Never had a drama & ran like a dream...

Be careful how u wire this setup up as u could do ur self & ur miners damage!

(The RM1000's have 6 x PCI-E connectors  so 2 x Rm1000's gives 12 PCI-E connectors)

RM1000's are quality power supplies at least for me, I've got a few and never  had an issue good wiring aswell.

I would not suggest for others on using 2 different PSU.  It it all works well it would run, but it could very well lead to damage if something goes wrong with 2 psu's. 

Have you taken the cover off to see if the heatsinks are caked with dust?

I think problem must have been solved.  I didn't notice the last log in till now- Last Active:    May 16, 2015, 11:44:37 PM

So I am thinking and hoping all is well for OP since he has not posted since then.

Opps, guess I didn't look at the dates either  :-\
