ANTMINER S3+ Discussion and Support Thread

[regedit]

Hello im new in mining what power supplier and how many watts is required for s3? Im planning to get 20 miners anybody here knows how to setup a plan like this? Please share thank you

One of these for every four s3's using 208v - 220v

Thank you, do you know other cheap alternative?

So! All units are hashing over 440gh (Two over 490), but only when using a cronjob to restart the cgminer service every 1/2 hour - 1hr depending on the miner.
Regardless of how long I leave any of these guys up to "stabilize", they always fall to 390-398 after 48 hours.

There's only one thing. I am noticing a rather high number of duplicate shares poolside since starting this restart routine. (surprise)
Is there a cgminer flag among the bitmain options to clear the asic of all work upon a cgminer restart? I know the A1 miners have a similar command with '--hwreset'

Restarting every 30 minutes is a bad practice.
Try replacing thermal paste grease and I think the issue will be solved.

I have two Antminer S3 that are both hashing at 440GBs. They both are running at the stock frequency of 218.75 but one if the miners has 20% HW errors. I have read many people are lowering the frequency to 215 or 212.75 to lower power consumption. I was hoping maybe reducing the frequency might help my HW errors. However I cannot find where to lower the frequency. I have done scrypt mining, but this is my first sha256 mining. If someone could help explain to me how to lower the frequency I would greatly appreciate it.

Underclocking early without having a solid reason will only lower your earning potential.
Are you sure you calculated your HW error % properly?
Post an image of your Miner Stats page.

after i do the reset to factory default, and login 192.168.1.99 using user name and password root, but all the pages i click is NOT FOUND? can someone help me out please

[tarmi]

I order 2 S3 today .. hope will quick deliver

If you ordered Batch 6, you most likely wont see anything for two weeks unless Bitmain says otherwise.

shipping date is on 12th of august.

am I missing something?

What Power Supply to use for S3? Sorry for newbie question. Please don't hate.
Does it work like this?

340 watts antminer s3 will work with 350 watts power supply?

and 10 or more antminer will work on 3400/5000 watts power supply?

This may be due to an ip address conflict or corrupted data.
First try reset to factory settings using the small reset switch on the front side of Antminmer S3.
Then go to WAN page and change you IP address of S3 to something like 192.168.1.92
If can't access the WAN page like before, turn off all the devices including this computer connected to the switch/modem/router.
Turn on the Ant S3 first, start all modem/router/switch, after 5 minutes start your computer connected to the same router/switch/modem.
Go to the Ant S3 web interface and change IP address, check whether its working. Report back your symptoms if not.

My lowly two B4 S3s are each powered by a Corsair CX500 (non-modular version with only two PCIe power connectors).  The CX500 accommodated the S3's 250M clock without any noticeable issues whatsoever which drew 425W at the wall at 29C ambient room temperature.  That's just under 80% load on the CX500.

The following are some data that I was able to jot down while in the process of exploring the S3/CX500 combo (hopefully the dude who's attempting to compile such data can use it).  Note that these figures are averages between my lowly two S3s (except for the ambient room temperature):

Legend:  Tambient/Tdevice/Wattage/Hash Rate

@ 218.75M (stock)
35C/45C/365W/440GHs

@ 225M
35C/45C/378W/453GHs

@ 237.5M
32C/43/400W/478GHs

@ 250M
29C/43C/425W/485GHs

I've set up my lowly two S3s in a V-Air (Vertical Airflow) configuration in an attempt to improve air-cooling efficiency (hot air rises).  Here are some pictures:

Pushing in cool air at the bottom and pulling out hot air at the top.


Since the less restrictive, widely-spaced chrome wire shelving now functions as a fan grill,
both intake and exhaust stock fan grills which are quite restrictive were removed for an improved airflow.

A lot of newbie miners are here and S3 is most of the bitcoin miners entry point now. Nothing wrong in asking here.
Yes it like as you did above. But, add more margin of safety.
25% room is recommended but atleast 10% to 20% should be there.
So for one Antminer S3 340Watts x 125% = 425Watts.
So, a minimum +12V/35A (=425W) is recommended for a single S3.
If not that, atleast you should have 400Watts on +12V single rail on a power supply to run a single S3.
So for more S3s multiply them to the above.

[Billbags]

I order 2 S3 today in bitmaintech.. hope will quick deliver


any body here purchase power supply in here (http://minersource.net/collections/frontpage/products/delta-dps2000w-with-adapter-board) ?  is minersource.net trusted?

I made that suggestion since he said he needed power for 20 miners. You don't need that for 2 miners. I would suggest 12v single rail(35amp per miner) with 4 pcie 6pin connectors(one wire per connector from psu). I use Corsair850tx myself for 2 miners, same as I used for my s1's. They are pricey, but they last. Most people are getting the Evga 1600 to run 3  s3's with also. And YES minersource.net is legit(ran by bobsag3)

Note: a cheap psu to run two "not overclocked" s3's

Thank you very much for this answer, Really helped me figuring out what to prepare for my s3.

QUESTION: If i ordered 10-20 unit s3 and i would like to send the mined coins to 1 address or 1 PC that  controls all 1-20 units. What hardware should i prepare and how to configure a setup like this. I dont totally need the instruction but please give me the idea.

Thanks to anyone who will answer..

Regardless of how long I leave any of these guys up to "stabilize", they always fall to 390-398 after 48 hours.

There's only one thing. I am noticing a rather high number of duplicate shares poolside since starting this restart routine. (surprise)
Is there a cgminer flag among the bitmain options to clear the asic of all work upon a cgminer restart? I know the A1 miners have a similar command with '--hwreset'

Restarting every 30 minutes is a bad practice.
Try replacing thermal paste grease and I think the issue will be solved.

I'm pretty aware how just how shitty it is, but unfortunately after re-pasting two units I saw a decrease in running temperatures but was still experiencing a steep drop off in hash after about 25-35 minutes. One of the units will spike back up to about 470 but never enough to average out to 440 without cgminer restarts.

I wish I could attribute this to poor labor skill on my part, but I'm just about 100% certain I don't suck at apply thermal paste. =/

Your miner has some series thermal issues as per my understanding.
Restarting is still a bad practice if doing it every 30 minutes. If it was once in 5 hours or so then no problem.
You average in 30 minutes is less bearable and for taking an average need to run atleast 2 hrs due to the range of move S3 does.
I advice you to findout the culprit in your miners, corner it and fix it.
Can you post your Miner Status page 5 minutes after starting S3 and 5 minutes after its hash rate is lowered, thats 5 minutes after 35 minutes.
We may try to fix if you are interested.

[bigredbutton]

Please forgive my laziness since this was likely mentioned earlier in the thread but is there a guide somewhere to silence or quite the beeping of the S3? While handy for a giant farm operator this feature is quite annoying for the home hobby miner. It seems as though the options under the web UI can't do anything about the beeping.

Upgrade S3 from its web interface to the latest firmware from BitMainTech website.
The beep problem is an already solved issue.

Thanks for the help.

What PSU would you get on newegg.ca to power and over clock two AntMiner s3s?
Thanks!

[JennaK]

Yeah but is that the over clock wattage?

[allcoinminer]

No its for stock. For overclocked put 390 instead of 340.

this may be a side question but this little turn on switch that www.bitamaintech.com offers

https://bitmaintech.com/productDetail.htm?pid=00020140731043909819C9CL7qf4064A

that you can use rather then a paper clip to start a miner...I assume this works with most if not all power supplies
like a paper clip ...they are both 'universal"?

anyone have one how does the puppy work?

I have a KNC Jupiter and just lurking here ..have not decided if I want to get a couple antminers yet
but have a KNC Titan on the way...and hell for the price www.bitcoinmain.com is asking for this I
should step up and get a couple...paper clip (newbie) that I used on my first miner last oct 2013
at 7,131.80 I was incredulous.....like turn head away and hope it worked (it did) still makes me queasy
would rather not use the paper clip ever again ! (shudder)

anyway recommendations? the paper clip is safer? thoughts?

you can't beat the price thou...as or right now it is $1.75 usd or .003 btc... heh .....(admittedly that is a lot of paper clips)

thanks for the info

Paper Clip is safe if you do it correctly and protect it from any loose or shot by sticking some tape over it.
