ANTMINER S3+ Discussion and Support Thread

[visdude]

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

The Corsair CX500 are pretty inexpensive especially when you time it with rebates, promo codes and now, an additional 10% discount with BTC payments.  It's been working for me:

Anyone else having issues with discarded shares? I hooked up my 2 new S3s yesterday and have 60k discarded vs 11k accepted as of this morning,

Also, One of the S3s does not show the fan speed but I can see it running. Is there an update for this?

3rd issue: One miner only mines at 415 GH/s. much lower than the advertised 440. Again, is there an update? The other one mines constant at 450 GH/s.


Thanks in advance.

Anyone tried powering 3x S3 with an Corsair RM1000 ?
I have 2 PSU's powering 4x S3 right now
I was thinking about buying 2 more S3
Can all 6 be powered by 2 RM1000 ?
Thanks !

Are these in stock clocks or you overclocked them? Which batch is this from?
Which Power Supply you are using and how many Antminer S3-s are connected in it?
Also post your Miner Status page here from both the S3s.
Also show your pool data by hiding the username and password.

no that psu will do 2.5 units.

the best psu for 3 is the evga 1300

You are already at the cross line for Corsair RM1000 Power Supply.
Corsair RM1000 have a single +12V rail having a maximum rated capacity of 83.3A.
That's roughly equal to 1000W. For running 3 S3 you atleast required to have 1020Watts on +12V rail.
But for safely running 24hrs every day you need to give some margin of safety.
Recommended is 25% headroom but 20% is also ok. So we should assume that for running a single S3,
425Watts need to be there from PSU.
425W x 3 S3 = 1275W.
That means, you can only run a maximum of two S3s in that RM1000.
Since you already have 4 S3-s and 2 RM1000 Power Supplies, for adding another 2 S3 get one more RM1000 or similar.
Else buy one having 1300W if you can leverage on money.

Wow just wow! Bitmain rocks! Avg 1850 on 4 s3's.....poolside peaks to 2th/s

Overclocked? This average is after how many hrs of continuous running?
Post an image of your S3 Miner Status page.

where was the overclock guide? I want to try to OC my miners

[muhhentuhhen]

Hey all, my S3-B5 is being shipped via. DHL. DHL wants me to send them email/invoice where is description of item in the package, it's value, shipping fee and transaction copy (paypal/bank transfer). What to do? What do I send them? I paid in bitcoins, so there is no paypal/bank transfer reciept to send them.

sorry for my poor english.

Can someone let me know what the Antminer S3 status showing -o-o-o-o -o-o-o-o -o-o-o-o -ooo-o-o  means?  Only one chain is showing this.  The other is oooooooo oooooooo .  Reason I ask is my Hash rate is 345 average.  Should be higher.

that is a bad chain.  

fixes may be:
 1) lower freq setting 212.5 has helped
2) reboot via gui  may help
3) make sure you have a good psu

Remember, Overclocking will make your warranty void.
Download the SSH client Putty from Putty.org and install it.
Open Putty and put your Antminer S3 ip address, enter your user name and password as root and root when prompted.
then type vim /etc/config/asic-freq
a file will open and press i there you can find the frequencies for overclocking.
Default stock 218.75 is there where three lines are uncommented.
Comment the three lines with # and uncomment the three line which you want to set as your clock speed.
Now press ESC button on your keyboard and type wq! hit enter button.
Restart your ant from web interface and you are now with S3 overclocked.

250M Frequency should give 504Ghs.
If you are not getting your miner is not capable of handing that.

Note: Plug all the 4 PCI power connectors before overclocking.

If the above are not working, go back to this thread and read last two days posts.
Your problem will get solved.

My Guess is power supply.  It's a cheap 520 watt from Best Buy.  Will try a Corsair 750w later today. 

How do I lower frequency?  Currently at 218.75.

Highly recommending to immediately replace your power supply with a new good quality one like you said.
I will recommend you to buy an 800Watts power supply unit for you instead of the 750Watts PSU. Keep and eye on the single +12V rail.
Why you want to lower your mining power? Some do for some particular reason like placing in office and so.
Underclocking is simple, uncomment lower frequency lines(3) to select lower frequency.

[JennaK]

Anyone from Canada ever buy from 112? How's duties and such?
I'm thinking of either getting a cx750m x2 to over clock 2 s3... Or a evga 1300w to over clock two of them.

I sent them a copy of my payment confirmation in bitcoins (order paid confirmation from bitmaintech) and they refused to accept it, since their system can only calculate "real currency".
Wrote a ticket on bitmaintech about this.

[jpchrist]

No shipping info on my last few Batch 5s.  Hope Bitmain can get them out today as promised. Already almost 10 pm in china and I can still edit my order.  Not looking good.

[MoneyMuscles]

one of my miners after 12-24 hours always shows a 15% slow down. No dead chips. A reboot fixes it.

after another 12 hours it shows that a chip dies, also reboot fixes it. Its the only s3 out of the 4 i have that does this.


Anyone else have exp with this?
