BITMAIN Antminer S3 support and OverClocking thread

The default IP address of the miner is 192.168.1.99,

Overclocking

You can overclock the S3 to 250MHz by first ssh'ing into the device,
and then uncomment the 250M clock speed lines and
 making sure other clock speeds are commented out.
The overclocked device hashrate is ~500GH/s at 250MHz.

I have tried 275MHz and 300MHz, and were no-go since the chip voltage in the S3 is set at 0.784V.

Run the following command from a Linux machine. If you have changed your device IP then use that below, instead of 192.168.1.99.

Code:

ssh 192.168.1.99 -lroot
password:root

vim /etc/config/asic-freq

Following steps are from allcoinminer. Thanks!

• Download putty from here first. http://www.putty.org/
• Open it and put your antminer ip address.
• Put root as username and password when asked.
• Then, type and enter the below.

Code:

vim /etc/config/asic-freq
vim is a text file editor. The asic-freq file is opened now.

Type

Code:

i

and comment by putting # in the default values and uncomment by removing # from the frequency set(freq_value,chip_freq,timeout) you want to set.
Type

Code:

!wq

to save and exit the file.

Uncomment the desired clock speed as shown below now and close putty. Restart Antminer S3 and you are running now at the new frequency.

Code:

config 'asic-freq' 'default'

        option 'freq_value'    '0982'  #250M 
        option 'chip_freq'     '250' 
        option 'timeout'       '16' 

        #option 'freq_value'    '1286'  #237.5M
        #option 'chip_freq'     '237.5'
        #option 'timeout'       '17'

        #option 'freq_value'    '0882'  #225M
        #option 'chip_freq'     '225'
        #option 'timeout'       '18'

        #option 'freq_value'    '1106'  #218.75M
        #option 'chip_freq'     '218.75'
        #option 'timeout'       '18'

A tiny red LED is visible when the board starts hashing



4xPCIE6pin power receptacles and  1 x RJ45 Ethernet port.




Operational. The board beeps real loud twice, after power up! Beeping can be disabled in the miner configuration menu.



Link for sound deadening the pesky buzzer . Thanks philipma1957

Solution to random beeping issues

General questions about the S3 now that mine have been hashing for a few hours...

1) Why in the name of all that's holy does it randomly beep?  Every now and then it just goes "BEEEEEP!" It's not like it's rebooting... it just decides to let everyone know, "Hey, I'm here!  Pay attention to me!"
2) I know the "o" in the miner status means "OK" and that "x" means "error".  What does "-" mean?

General comments:

1) At stock clocks it hashes almost exactly to spec on p2pool (my local node).  Initially it was around 450GH/s, but after settling down and going for a few hours now, it's about 439GH/s.
2) Overclocking it has far less effect on p2pool than on another pool.  For example, at 250, I get about 455GH/s on p2pool.  I get 500GH/s elsewhere with the same settings.

The beep is internet connection lost or failed to get work. It will retry to get work or listen for the internet connection up to a point. If it keeps hashing then its doing what its supposed too.

The config now allows you to turn it off if it is really annoying.

I did turn it off, yet it still will randomly just let out a beep.  It hashes away happily...then BEEP...still hashing...I think I'll beep now...

It happens at all clock speeds on every pool I've configured (my local p2pool node, another p2pool node, Eligius, BTCGuild, and yes, the pool that shall not be named).

My miners were doing the same random beep as you describe, I setup the dchp server to fix an ip for each and the beeping stopped. Too many iDevices on the network seemed to cause too much conflict for temp. leases.

Total noob here.  Could you please provide a step by step guide to overclocking the S3. Thanks.

Thanks Ill give that a try!

[oskuro]

And difference of W without OC and overclocking to  250MHz?
And is this secure?? I mean... there´s no risk S3 explodes or something? xD

Temp goes so high with 250 MHz? thx!

[jimrome]

can someone tell me if opkg is locked down?

edit: also, what's the flash utilization ('df -h')?

[fragout]

Tks for the guide. I am still awaiting delivery. Do you need to connect the other 2 power connectors to OC? and what is the temp difference between OC and default?

[Opnsrc]

power draw diference ?

Need to know this 

This.

Goxed,

You got a really nice unit if it's remaining stable at 250 clock and 504GH/s, congrats!  Mine apparently are part of the batch that caused Bitmain to set the clocks back to 218.75.  I tried 225, 237.5 and 250.  I would consistently get "x" and "-" in the ASIC stats and the units never got anywhere near the 504GH/s you're showing.  I left them running like that for 7 hours while I slept last night, hoping things might get better over time.  When I woke up and checked, Ant 1 was averaging 450GH/s and Ant 2 was averaging 387.  At 250 clock.  I set them back to stock and after 13 hours I'm at 441 and 439 with 0.0002% and 0.0004% HW errors.  All ASICs are "o".  It's definitely not a power issue - I've got an EVGA 1300 G2.  I even went so far as to hook only 1 up at a time on the PSU to see if it made a difference.  All 4 PCI-e connected.

Also, that solution for the random beeping did not work for me unfortunately.  They still randomly beep at me.  It's like they're just letting me know they're still going.  If somebody does come up with a valid solution to this, I'd be very much... well, my little lady will be very much appreciative of it

As for temps and fans, mine are in an ambient 22C room.  Ant 1 shows 38/39 and Ant 2 shows 39/40 on stock speeds.  Fans are 1560/1380 and 1620/1380, respectively.  With the same PSU as I have, philipma1957 reported 665W at the wall to run them both at stock.

And is this secure?? I mean... there´s no risk S3 explodes or something? xD

This has me curious as well. I never did overclock the S1's I had, but I'm thinking of overclocking these dudes. I'm really hesitant, though, on the count of them already needing to clock them to 218.75 stock :|

Was thinking of nudging one up to 225, but don't want to risk burning my house down.

i have my S1´s overclocked and no problem. But with S3 im not that confident to OC

I would like to know difference of W for OC and non OC and temperature also

[jamesc760]

Anyone with info on overclocking steps between the 218.75M and 225M? Like 220M. What are the values to add in?

Thanks for the help.  I was able to login via putty and get the screen with the freq values.  However, not sure where on the screen to type the "i" and "!wq" commands.

[Duce]

Pre <esc> then type :wq
This will take you back to the prompt. Then type "exit" to ensure you close the connection. At this point you can close your terminal program. Reboot or power cycle the Antminer to complete the change.

Just press "i" on the keyboard when the file is opened.
The other one was a typo. After editing you need to press ESC button and type the below code and press ENTER to save the edited file.
Upon window close PUTTY will auto close the connection. Or may manually exit as said in the earlier post.

do yourself a favour and install nano, it's an easier to use (albeit less capable) text editor.
opkg update
opkg install nano

A bit OT but maybe you can answer this for me.

Either in nano or vim - is there a shortcut for select all? I can't seem to find it and replies from searches online don't work for me.

Its not possible to use a single shortcut the select all in nano or vim.
Multiple shortcuts will work that's a hard job. Using mouse will be more easy.
An enhanced version of vim called vim-enhanced may be used.

You can try that in visual mode
sorry! visual mode does not work on the antminer's vim.
