[Setup & Troubleshoot] Bitmain AntMiner S1 180GH/S miner

[Darthswan]

PC Power & Cooling is a very solid brand. They don't have the fame of companies like Seasonic and Corsair which is too bad.

Ah okay, can the 750 handle a ~800W load continuously?

That's a bronze 80 plus PSU with 60a on the 12V line; the max you'll get out of the 12V line is 720w with 17% more pull from the wall (842 ish watts if you managed to get 100% usage on the 12V line). You'll barely be able to get 2 non oced ants running on that.

edit:

this is based off of other's experience of seeing 320w at the source for ants. If you have 360w ants at the source you will likely see some interesting things going on with your PSU.

Edit2:

To answer your question simply and nicely; no.

[MrTeal]

PCP&C was a very solid brand, though I'm not sure how they've done since being bought by OCZ. That PSU is a Seasonic designed and manufactured unit, but the design is almost a decade old and technology has come a long way since then. Efficiency at 750W is tested to be under 80%. It would be really pushing it to try and run two OCed S1s at 400MHz+.

So what do you guys think, will I be able to overclock Two Antminer's with this PSU?  Or am I pushing my luck?  It peaks at 825W

I'm not sure if 60Amps will be enough to run 2 miners, but I've not run 2 on my 750W yet (been working through other issues), although it has 4x40Amp rails which would probably be better suited.

If I overclock both Antminer's and it turns out to be too much for the PSU to take, what is most likely to happen?  It will just power off right?  I won't destroy anything right?

if you are pulling 400W from each miner, overclocked, it won't work.

Yes but my Power Supply has a peak rating of 835 watts, and cost me 200 dollars in 2007.  I'm pretty sure PC Power and Cooling isn't some joke PSU maker bro.

So you will run your PSU at peak continuously?  What is its efficiency at peak?

Not sure what the efficiency is, but I know PC POWER AND COOLING is pretty much Master Race as far as power supplies is concerned.  When my antminer's arrive from China, I'm gonna blast this fucker with all she's got, I'm talking 400+mhz here.  Hopefully I'll save 100 bones too.

seriously, read the box properly. When it says 750W, peak at 825W it means that the 12V rail can be maxed out at 60A (720W) for a short burst of time while the 5V and 3.3V rails also draw their full powers (another combined ~105W).

You SHOULD NOT run a PSU 24/7 at the full rated capacity. You CAN NOT run a PSU 24/7 at its maximum (short-burst) capacity. You would burn the thing out in a matter of hours, days if you are lucky.

you have 60A on the 12V rail. This is 720 Watts.  I would not advise loading more than 680W on this so that you have a little bit of leniency from the PSU. This means that you can only run 1 antminer per PSU, or 3 antminers between 2 PSUs

Will this PSU power 2 units:

Corsair Professional Series Modular HX1050 80PLUS Gold

And if I want to try overclocking, will it be enough, or do I need a 1200?

More than enough, I run 2 overclocked (400MHz) ants on a single Corsair AX860i.

It can probably handle 3 overclocked ones but it would be cutting it EXTREMELY close ;P I run 2 overclocked ants/1000w Fractal design Newton R3 (80+ platinum) and the ants are pulling around 750-760W@wall. A Solid 1200W supply would be able to handle 3 overclocked ants without any problem.

[Moebius327]

I did a stupid thing and bought some 630w Thermaltake without researching much. Do you think one PSU will handle 1 overclocked antminer? This is what I got



FAILED: DO NOT BUY THERMALTAKE 630W BERLIN for ANTMINERS !!! It works, but I was getting around 170Gh/s before switching to a new Corsair.

[Bismarckbkk]

Looks good to me, ive been running 5 ants since december and never had a problem with single rail. Alternatively you can combine the 4 pins.

[giletto]

It's possible, but they got really warm. And mostly you need to plug a CD/DVD Drive too, or the PSU will not run on-load longer then a few seconds.

Hi guys,
On 4 out of 5 my new Antminer S1 miners, fan doesn't working automatically. It's just sits on 0 RPM. I checked all these fans on working Antminer, they are fine, regulating RPM nicely.
I tried different 2-pin 120mm fans, they working correctly, so power is OK on Antminer ports.
Sometimes, when I plug-unplug fan pins, it start working with speed regulation like nothing happened, and stays on, until I power cycle Antminer.
When I partially push fan plug into the port (so it's not touching last, blue wire) it's spinning on 100% making much noise, so fan looks like is 100% working OK, but miner it's not telling fan to spin on correct, average speed.

Do you have any solution for that, guys? Why fans are not working automatically?

[JohnC.]

Looks like some new firmware "feature"?
I just received a few miners and they all have the behavior you describe, when i poweron the miners i'm used to the fan starting but these stay on a stand-still.
But when the miner gets up to temp they start spinning but they make an loud knocking noise, even when i take them off the miner.
So it seems like i need to replace these fans Or look for RMA options.

I noticed they are using another type of fan compared with the previous miners, the old ones had an silver/black sticker these are yellow/black an got the following details: FXDS 140208

[Darthswan]

Who's updated their firmware?  Any new features?  i'll look into doing this afternoon..  Someone did a nice video on youtube.

Hiya,

  my ants are up and running! Special thanks to everyone who helped on this forum and tech support from Bitmaintech.

Appeared that there where 2 problems... network settings were ok...but had 2 crappy (new) 850W PSU's. They couldn't cope with the wattage demand.

As for the Ant that wasn't reachable after the hard reset... Done a hard reset again following the guide lines of Bitmains tech support... But was still not reachable.. thought: lets try the IP I changed it to.. 192.168.0.98 and there was the login page...

Again many thanks for all support!!

I edited etc/config/asic-freq to 400 and I am getting 190-200G, but one of the boards is showing
 

Code:

ASIC status
xooooooo oooooooo oooooooo oooooooo 

Code:

GH/S(avg) 189.34 GH/s

Unplugged and plugged the PCI-E cables but after running 5-10 min it shows "X" again. Using Corsair AX860 PSU.  Should I get back to stock clocks? Thanks in advance!

Fixed after changing pools.

[Aexcu]

More than enough, I run 2 overclocked (400MHz) ants on a single Corsair AX860i.

Curious, are you behind 110v or 230v? Supposedly PSUs 'perform better' with 230v?

I just got my S1 but can't configure it at all, 192.168.1.99 the IP address on the unit brings up nothing.

Going through your steps here

Start Button  >>  Control Panel  >>  Network and Internet (View network status and tasks)  >>  Change adapter setting (Left side of the screen)  >>  Local Area Connection (Double Click)  >> Internet Protocol Version 4 (TCP/IPv4) then Click on “Properties”  >>  Select Use the following IP address:

When I click change adapter the Local Area Connection says Unidentified network.  Double clicking just gives me the status page so I go to properties.  When trying to modify the TCP/IPv4 Properties I fill out the IP address but then I can no longer Obtain DNS server address automatically, it forces me to fill this out.  Even when I put my DNS info in there I have no progress

Fill the IP address to 192.168.1.X  where X is anything but 0, 99, or 255 .  Leave DNS and Gateway entries blank and click ok.

Connect the S1 to your computer ethernet port then click start and in the "run" box, type CMD.  When the command prompt opens up, type:  ping 192.168.1.99    

If it the result includes: Reply from 192.168.1.99   then you're good to go and can login to the S1 through a web browser at that IP.

I got my device and started it up, it ran great for the first day then the hashing dropped by 50%. I looked at miner status and saw that I had the "xxxooo xxooxx" problem. I shut it down, rebooted, problem solved. Eh, not quite, happened again later and within a few days my miner stopped hashing altogether. It was still running but when I tried to check the miner status it logged me out of the webui. I logged back in and the miner status page was blank.

The device responds to ping but when I try a command via webui or ssh it stops responding and typically logs me out. I then have to log in again to complete the action. I'm unable to update firmware, the miner still isn't hashing, and the logs show no errors that I can detect and all services appear to be running.

Has anyone had an issue like this? I've contacted Bitmain support but they have basically been non-responsive other than "we're researching it" whatever that means.

I just tried running through all of that and get Request timed out. 4 sent, 4 lost
