ANTMINER S4 Discussion and Support Thread

[luthermarcus]

Unfortunately, this 80 Degrees C is the only option from the control panel.

Hi,
Is there any way that i can change temperature from 80 to 70 degree?

  Please implement and adjustable setting for this with a max temp of 80 degrees.   

Yea it's like talking to a brick wall good luck with that happening.

[MyRig]

If you are having the heat problem, the 1600W PSU from http://www.bitmaintech.com with a breakout board may perform better than the original S4 PSU, however, it also has performance temperature threshold as well.    One easy solution be try to find a box fan and place it in front of your miners and increase the air movement and it may.  

ERROR LED, you may unplug it, remove it from the S4 and place it in a cold place for a few hours, to make sure it is cold to the touch and try plugging it to the power cord and see if it works. (or let it sit in cold for a day unplugged and try again)

OK So got my PSU back after sending it to Serbia for repair (the only place in Europe) - cost a lot in postage

Installed and got it working ok and worked fine for about a week then the same thing. Orange LED on and Red LED flashing on the back

Got back in touch with the service guys who says it is overheating protection - has been unusually hot in UK recently.

But they cannot tell me how to reset the PSU as against company policy.

Anyone know about this and how to reset the PSU?

Or is it possible to use the ones for sale on the antminer site by adapting the cable to take the older style connectors (not PCI)

thanks for any suggestions

I'm in need of that Psu for my S4 but how do I order it with ring terminal ends and not the pcie connectors?

Yes. Please do this.
Or tell us how to configure the cgminer internally.

I was asking this question on another thread about this PSU - this is a reply I got

Is it possible to adapt this PSU to fit the older style S4?

Not with the PCI connectors but with the ones fitted with a nut and bolt?

Yes. BITMAIN AntMiner APW3-12-1600 PSU Series  has its own separate power board to connect the PCI-E cables with S4 cables.

Named S4 Power_Board V1.0



but you still need minimum 210V

This board comes standard with the PSU - have picture of the board but cannot see how to insert it in this message.
Hope this helps

OK thanks for the suggestions - will try what you suggest - but I was wondering if there was a reset button/mechanism that could be initiated to reset it after it tripped.

Bet there is but Antminer not letting on.

How hot of weather are we talking about around miner?   Also what CFM fan did you try on it?

Hi There

It was unusually hot in the UK recently about 30 deg C last time I checked before it switched itself off the machine was running at about 63 deg C
I have them in the attic as I don't have a cellar - so as hot air rises.......
Have some S3's running there didn't seem bothered too much - must be the built in protection for the PSU that got triggered

Yes with having them in a attic you will have the hot air from the house rising, that is true.   Not all attic's are equal.  I would still try first put a decent CFM fan pushing extra air through the S4.  For summer I have some pretty big fan's pushing air through some of my gear.

Some things you can do is if you have attic vent's try putting fan's where it's hottest to push air through the attic vent.  Turns it from passive to a little active depending on what CFM fan you use.

If it get's really bad you might look into replacing gable fan (assuming your using one).  I had a lot of gear in a area with a gable fan and switched to http://www.homedepot.com/p/QuietCool-Professional-3013-CFM-Power-Gable-Mount-Attic-Fan-AFG-PRO-3-0/206047381 did a lot better at exhaust with all the extra power.

Can some explain the difference between the S4 & the S4+

I understand it has more chips & it goes faster but does it have better w/gh?

If so & the chips are the same what can be done to bring our firmware inline with it??

PS Bitmain wheres the underclocking firmware?

Biggest difference to me is S4 can run on 110.   If you want the bigger and more powerful S4+ you will need "(205V - 264V AC)".   

The S4+ does mention a better power efficiency.  Early S4 firmware had freq and voltage as far as underclocking.  In later firmware the feature of voltage was taken out I believe.

I have an antminer S4. It powers u p but does not connect or hash.

Here is what happens when I turn on the power.

1) Fans power up at high speed. The screen has power, but no text. Green LED next to screen is lit.
2) Fans power to a lower speed. Screen is still lit, but no text. Green LED turns off.
3) the word "Antminer-" appears on the screen
4) The 4 line screen display comes on line. Green LED is not lit.
5) the display says:
     Antminer S4
     127.0.0.1
     0 GH/s
     Max 0 C

The green light next to the display does not come on either.

6) this is as far as the boot process goes. It never acquires an IP address, or start to hash.



Steps I have taken to troubleshoot:

1) check the ethernet cable, power cable, connection. I swapped in a functioning S4, and it powers up and connects to the internet and hashes.

2) Swapped the microSD chip from a functioning S4 with the chip from the non-hashing S4. Same results, Powers up but does not hash (no change in other words)

3) checked all cable connections. all appear good.

4) checked the voltage at the power leads to the board with a multimeter. Reads 25 V

5) Used a port scanner on my network before and after powering the Antminer. There are no new connections.




Can you please suggest additional troubleshooting steps?

With working S4's did you try to switch PSU and see if that does the difference?    PSU's sadly have not been the greatest in some units.

I will have to give that a shot.

I don't have extras, but I can swap one out from another machine.

He said he measured 24v though.
IT is DC correct? Is it the PCI connectors or lugs?
Did you check each plug?

I would have thought SD card until you said you tried one from a functioning unit. It obviously isn't getting an IP if all voltages are present.
So then it would have to be the beaglebone itself, maybe the SDcard port?
Or, something as simple as the CAT5 cable or the port on your switch?

By changing out PSU with working one he does not have to check each plug or connector.  Its quick and pretty easy.  The BB chances are is working or chances lcd would be blank and he also checked cables.  

He mentioned he checked ethernet cable so this would be the CAT5.  Although swapping it to test again is not a horrible idea.  

I would make sure SD card again to make sure to eliminate software issues.  If swap again make sure it's completely seated.  But checking PSU again I think would be worthwhile.  What leds are on the PSU when you turn it on and with it not hashing?

Sorry for the confusion folks. Typo.

The voltage at all 4 boards (the lugs) is 12.0 V 

The voltage at the pci-e connector is 11.98 V

Ethernet cables have been swapped also. No change. Swapped ports, and even swapped out the switch. Also other machines work on the same port, and the same switch and same ethernet cable works just fine.

I was thinking about swapping out the beagleboard (with one from a working machine) and see if that is the issue.  Never done that, but should not be that difficult. Can it? Although it looks like I have to pop out the power supply to get to the beaglebone.

[sloopy]

Yes, you have the beagle to try, and you can try each hashing board alone.

I did miss where you mentioned the network cable had been swapped, and hey if you swapped ports with a functioning miner you know it isn't that side of things.

When swapping parts, especially control boards - you must have the backups saved to the disk.

Antminer S4 is very noisy. Is there a way to make them silent? Any super silent fans/model for it? What do you recommend?

It get's hot so I would not just switch fan's.  Most likely you would need to underclock and switch fan's to get it quiter.

It was in no way meant to be a quiet machine though, it was made for hashing power.
