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

[Raptor2213]

What are the acceptable, or rather, max temps for the S1? Mine are 48-49c, which seems to have caused over 6% HW errors, or about 6-7gh/s off of my speed.

Anything under 60c should be 'acceptable'.  Generally somewhere between 40-50c is where you should be seeing your temps, assuming 70-80f ambient.  You probably won't see issues until closer to 70c.  If you're getting that high an error rate, you might need to clock it down a little (if overclocked).  If stock, there might be a problem with your miner and you might consider replacing it from BITMAIN.  Not all units will clock up to 400Mhz with low error rates.

I can't find specs for your first PSU, but the second one has 3 12v rails that split the 480w available at 12v, so that could be why you're not getting enough power.  Look under the specifications tab on the link you posted. Ideally you should use a PSU with one rail for 12v with enough power.

Are you using two separate pcie wires or one wire with two connectors?  You should use one dedicated wire for each blade.

Right now i'm using one separate pcie 6 pin cable (it's stripped now) for the blade without controller and 3 separate stripped ATA connections (each 1x12v and 1xGND) for the blade with controller.
But this is a very old PSU. Much older than my Enermax.

So you don't think my miner is broken? Without a proper PSU it's totally normal that the fan is working only, if i single-connect the blade without the controller to the PSU.

Thanks!

Or 3 even (per side)
Yeah a PCI-e cable has 3 pairs to split the 15A (per side) over - so about 5A per wire.
Even splitting it to 2 wires per side tends to make them get warm.

Just for fun.



I'm will buy a new PSU and try it again. I really hope it is not a broken blade.

And i know what you mean. I don't know how it looks inside the PSU. Just because the cables are separated doesn't mean they are not splitted.

thats your problem there. That looks like it came from the 'used' bin at a salvation army. Its pretty important that you use a quality power supply (single rail, brandname, modular if possible, minimum 600W) in order to get good results.

I expect you are either tapping multiple wires off a single rail or the rails are generally poor build quality. Its not at all uncommon in PSUs not rated 80+ bronze or better.

You can try the 2x2 pin ATX MOBO cable.  these usually have thier own rail in a multi-rail supply since the mobo is expected to draw lots of power

Hey all I need a Recommendation on a PSU for 2 Antminer S1's that Will handle them being Overclocked with no Problem and i need it to Be at least a Bronze 80+ and in the $180 or Less price area

thanks for helping I would have just been guessing it was broken I sent a little btc your way. I would have been just guessing it was broken...would a 850w thermaltake suit your needs...lol

Thank you. I even tried it with a the available Pentium 4 2x2pin 12V power supply and 1 ata cable. Is was thinking about trying it again with the 2x2pin mobo cable. I guess you mean that one from the 24Pin Main-mobo-plug.

Yeah. I will try this but i don't think it will work. PSU is worthless for this purpose.

If it works i will posts results. If not i will wait for my PSU and will post results then.

Thx again!

What sort of HW error rate should I be seeing?  I have two AntMiners I just got up and running today, up time is 5+ hours and here is what each is showing:


#1)   Accepted 7507    Rejected 13   HW  2695  Utility 21   Discarded 852   Ave 179.18 Gh/s   Temp 48
#2)   Accepted 7917    Rejected 22   HW  3010  Utility 22   Discarded 966   Ave 178.59 Gh/s   Temp 46


Both are pointed at Eligius with a backup at BTCGuild and both are running at factory settings (no overclock).

thanks for your help

Yup, not all 500w PSUs are created equal.  I had a 500w PSU that was barely sufficient to power one of the two blades.  It was never intended to be long-term.  I just had it lying around.  Get a better PSU (80 plus certified), and you should be doing ok.

That's all bullshit. You know nothing about me. I'm serious.

I will order one today and will have it express. Thx.

I've ordered a Thermaltake Berlin Netzteil 630 Watt 80 Plus. But there was no express available. It will take some days.

You are looking at the wrong numbers.

HW is diff1
Accepted - ignore it
Difficulty Accepted is diff1
Rejected - ignore it
Difficulty Rejected is diff1
Utility - ignore it
Work Utility is diff1
Discarded - almost meaningless

Edit: you are mining at ~100diff, so the numbers you are showing are very approximately 100th of the diff1 values
(looking at the API summary will show that)

So you are saying that the stats there are only confusing us, and I don't have 6% HW errors? I'm mining at btcguild, the diff in my Miner status is 128 under "Diff". Although I am curious what Diff1,DiffA,DiffR,DiffS,LSDiff all mean.

Well the screen is documented clearly in cgminer
https://github.com/ckolivas/cgminer/blob/master/README#L534

AntMiner's lack of documentation in the web interface is their fault.

Though my post above I thought it was obvious that DiffA means Difficulty Accepted.

say what lol are you joking?

[wolf_miner]

@Kano, I saw a project called "cgminer LCD Stats" is possible to read the S1 API data using a similar project, or editing the original python script?

Thanks W_M

You need to enable the API for remote access
This means you need to edit /etc/config/cgminer
Firstly work out what your local network is - e.g. 192.168.0.*
Then modify this line:
 option api_allow 'W:127.0.0.1'
to something like
 option api_allow 'W:127.0.0.1,192.168.0/24'

Then use this (which is what I use of course) and read the README! ...

Thanks Kano you have solved the problem for me.
My LCD is on the way, and i will receive it in a few days, i had ordered it about one month ago from china supplier.
