Topic: [Setup & Troubleshoot] Bitmain AntMiner S1 180GH/S miner - page 75. (Read 452359 times)

thanks for the fast reply.

i disabled NTP. but i still get the same output in the syslog. (rebootet, and dis- reconnected from PSU)

this is the syslog-output:





i just checked the running processes and it seems that the antminer is configured
to start ntpd automatically:



may this be the issue?

cheers

Disable the NTP servers.

hi,

my miner is powerd on, and i can connect via webinterface. but the antminer is not hashing.

In the syslog i see that the ntp is not syncing:


but i changed it already to:



so why it keeps trying the preconfigured ntp ??

i rebooted the antminer and i dis- and reconnected to PSU.
I have a "bequiet pure power 530W psu", it s connected to the antminer via 2 x pcie.


kindly
bitsta

Does anyone know how to change the fan speed? I got 2 S1s, one shipped running at 3780rpm sounding like a jet engine the other 2400 rpm. Is it just a simple config change? Thanks in advance.

cool!  Glad it worked out.

I was able to open it up in vim for some reason, while vi kept pretending it didn't exist suddenly... no idea why.

is the cgminer file gone or maybe it's just the content of the file?



You can always scp a cgminer   file from another ant to your local drive, edit it and then scp the file back to each miner having the problem to the same location   /etc/config

If you're running Linux on your current machine:

If you need a copy of the original /etc/config/cgminer  file, I think I have a copy.  Were you trying to open up the api port on the Antminer?  It seems to be open by default as I'm able to access my Antminers using Anubis, fwiw.

Just got 2 antminers today, SSH'd into them, typed in "vi etc/config/cgminer" and added "option api_allow 'W:0/0" on a new line. Saved the file, rebooted the antminer and now etc/config/cgminer appears to not exist whenever I try to open it up again on both antminers. Resetting the antminer does not fix this.

Any ideas what I can do?

I've set up several units before, and for the first time I am having problem with 2x units I received today.

1st unit. Fan very loud / full speed, unit beeps, stops hashing. I see briefly under miner status that the second blade shows temp at 127 degrees Celsius before unit stops hashing, runs fan at full speed, and beeps. My guess is a possible defective temperature chip, or connection. Unit thinks it is over heating, puts fan on full speed, and gives a warning beep, then basically kills off cgminer running.  It is a defective 2nd blade, as I have crossed wires and control board works with a different blade. I have done all the usual, reset to defaults, reload newest firmware version. I really believe it is a hardware problem with the second blade.

2nd unit. Dead, DOA, Dead. I plug in and turn on unit, and it immediately trips power supply, surge protector, just will not turn on, seems like a hardware short somewhere on the first board, and the controller unit. I have double checked and all wires seem to be plugged in, and I do not see any chips missing, misaligned,  or blown. But I am no board expert.

 I am guessing I could take the first blade, and control unit from the 1st unit, and put it with the second blade from the 2nd unit, and I would have 1x totally dead miner, and 1x perfectly working unit, but I want to get the ok from bitmain before I swap blades.

Has anyone had the max temp issue and found a way to fix it. I have set up dozens of these, and this has been my first time with an issue I have been unable to solve.

You was partially right. Bitman uses female wifi connector, so male wi-fi antenna needed for antminer. I used some antenna from ASUS router, this antenna also was female. Problem was solwed by 5 mm wire inserted to connector. Now wifi scanned and found&works perfectly  

Absolutely.

Of course, it's possible to run a S1 on a weaker PSU, but it's not efficient at all to run a bronze PSU at it's maximum 24/7 - far better to use a more efficient PSU that's well within it's limits, it'll save on costs in the long run 

If you do not overclock them you can do fine with a proper psu giving 550+ watts but what some claim your are far better of with a more powerfull one
The highest efficiency is still when the psu gives around 50% of its power so in all buying a cheap weak psu limits you and costs you more power.
Second if you do want to overclock you sure as hell will see how much a ant can pull.

If you do not live in one of the expenssive power costing countries you can oc as much as you want, but for me it turns out that i better downclock the ants so they use less juice at a still decent speed.
I think in my case lowering clock speed below 350 will be more rewarding for me.

WiFi is hit or miss on these and I don't think its actually supported, they just happen to be using a WiFi router as a control unit.

Your best bet is to get a cheap WiFi extender box with an ethernet port and plug into that. I have several hooked up like that and they work fine, but either way you have to make sure you have good WiFi coverage without interference.

Cant really help you, but I had this happen to one unit.  Sometimes finds radio sometimes not.

Would up just using wired WAN.

Hi. i just got my antminer WiFi there not working. Working only as AP, not working as a client. Also wifi searching not working.

Tried:
1. Reset settings by web-interface.
2. Reset settings by button at pcb
3. Tried update firmware to 2014 version

I'm shure that it is software bug, but dont know how to fix it ;(

Anybody can help?

I've been running an OC'd ant @195Gh/s on a 520W bronze for over a month...

Ive run 2 stock ants before on a Seasonic platinum 660.  But it was only for 24hrs before I realized then I moved them to a 760 watt unit. It has 7 year warranty anyway.

Screenshot from the Power Usage of a non OC Antminer S1:


You do not really need 700W+ I think.

There's no point in getting a cheap PSU, it's asking for trouble. You need a minimum 80+ Gold 700w unit to run one unit safely. I run two on a 1000w PSU no problem.

If you don't have the cash, but have the BTC, I can order one for you from Amazon.co.uk with free next day delivery - see my sig
