BITMAIN Antminer S1 support and OverClocking thread

[-ck]

Hey is there a new firmware with a version of cgminer which does not hog cpu?
Thanks

Still waiting for them to post their current code before I can see if I can do anything with it. Also I don't know if I'll be able to create firmware for it or just cgminer binaries.

Dear goxed
Can you explain me how to overclock antminer by using linux step by step ?
I got raspberry pi with minepeon .
kind regards

Sorry, but antminer has a built in host computer (similar to Avalons). You need to modify the files as instructed in the first post of this thread. since cgminer source is not available (pls see the previous post) this is the only way to OC at the moment.

How to overclock your miner to 400MHz / 205GH/s

The miner will draw 500 - 525Watts after this setting

A) ssh into your miner

B) edit the following file
/etc/config/asic-freq

C) change timeout to 36, freq_value to '0780', 'chip_freq' to 400.

Code:

root@antMiner2:/etc/config# vim asic-freq

package 'cgminer'

config 'asic-freq' 'default'
        #option 'freq_value'      '0780'        #400M
        #option 'freq_value'    '4d81'  #350M
        #option 'chip_freq'     '350'
        option 'timeout'        '36'
        #option 'freq_value'    '4c81'  #325M
        #option 'chip_freq'     '325'
        option 'freq_value'     '0780'  #350M
        option 'chip_freq'      '400'
        #option 'freq_value'    '0580'  #300M
        #option 'chip_freq'     '300'
        #option 'freq_value'    '0981'  #250M
        #option 'chip_freq'     '250'
        #option 'freq_value'    '4f02'  #190M
        #option 'chip_freq'     '190'

Goxed i will try one more time .
Can you tell me where i can find the window with these options to change in main menu for antminer ?
Are you running overclocked ??

[yuancraft]

dear goxed can you helping me ?

Actually you have to ssh into your miner. There is no GUI options at the moment. All command line. Please make a backup of your firmware before tinkering if you are unsure.
Thanks

Working great thanks goxed!

Hey goxed these were posted over in a different thread... what do you think about pushing even higher?

400   3.2   4F81   35
425   3.4   5081   33
450   3.6   5181   31
475   3.8   5281   30
500   4   5381   28

I am thinking with some better cooling it might be possible

[bclcjunkie]

goxed have you tried? i've got lousy PSU atm, need to get a better one before overclocking..

excellent tip.  was easy to do and increased my hashing by over 10%.  will definitely tip you

edit - tip sent.  cheers

i tried the 425 setting and i got a lot of hardware errors and was hashing more slowly than at 400.  if you're going to overclock best to stick with 400 for now.

When I SSH into my miner I get

Can anyone provide the steps or a video tutorial ?

Sure you will gain tips for this, myself being one of them

Thanks

After logging in via SSH the following steps:
1. type:  "cd /etc/config"(without the quotes) and hit enter.
2. type: "vim asic-freq"(without the quotes) and hit enter.
3. hit I button to enable "edit mode" and adjust the settings, lines beginning with # are ignored.
4. after you're done hit the ESC button to exit "edit mode".
5. type ":wq" (without the quotes) to execute write and quit.
6. you'll be back in the command line, type reboot to restart your device.

You can check your frequency in the web interface miner status page.
If everything went ok, you're mining with higher speed

Then you can donate to me for providing you with extra steps to unleash ultimate hashing power 15j3fDzunHtoTsDH7MAKQQiG95q5yWYTfk

Keep looking at your HW errors to make sure your device isn't frying up.
I've added some tiny heatsinks, and running 400Mhz but still 3.3% HW error.
But my Antminer is using the Corsair AX860 80+ Platinum PSU and @400Mhz it's sucking around 395W out of the wall-socket

[madpoet]

How can you tell what your hardware errors are?

also note which miner version/revision you have (look at OP's post below).  mine were both the 2013/11/18 build date, which i found out easily after opening the asic-freq file (since it had the same format as he shows below).

make sure once you do step 3 above that you place a # in front of the 3 original 350M lines and remove the # from the 400M lines.


C) change timeout to 36, freq_value to '0780', 'chip_freq' to 400.
For miners with build date 2013/11/4

Code:

root@antMiner2:/etc/config# vim asic-freq

package 'cgminer'

config 'asic-freq' 'default'
        #option 'freq_value'      '0780'        #400M
        #option 'freq_value'    '4d81'  #350M
        #option 'chip_freq'     '350'
        option 'timeout'        '36'
        #option 'freq_value'    '4c81'  #325M
        #option 'chip_freq'     '325'
        option 'freq_value'     '0780'  #350M
        option 'chip_freq'      '400'
        #option 'freq_value'    '0580'  #300M
        #option 'chip_freq'     '300'
        #option 'freq_value'    '0981'  #250M
        #option 'chip_freq'     '250'

        #option 'chip_freq'     '190'

        #option 'timeout'       '70'

Have found another way actually as well, Download the backup of the firmware then edit there make copy of original

Edit the correct file then reupload. worked like a treat

Thanks

1.  First thing to do is get putty.  google it download putty.exe
2.  Second step is open putty.exe
3.  Inside the putty program put the IP of your machine in the hostname field.
4.  Click Open
5. accept the prompt to accept a key or connect to the host
6.  If the client connects you will get a prompt that says "login as:" .  Put your username in that field.  default username is "root".
7.  pw is "root".  hit enter
8.  once you logged in successfully type  "cd /etc/config" hit enter
9.  type "vim asic-freq" hit enter.  A terminal text editor should show you the config file.
10.   Now pay attention there are at least two different asic-freq configuration files out.
If your config has mainly numbers for the "option 'freq_value" such as "option 'freq_value'     '0780'  #350M"  settings then you have the top config goxed posted.  if it is "#option 'freq_value'     '4d81'  #350M" you have the other config.
Also note that the default setting does not have # in front of the "#option" setting.  The 400 setting on my config is commented out with #.  Un-comment that shit. :0
11.  top config should have these settings:  config 'asic-freq' 'default'
        #option 'freq_value'      '0780'        #400M
        #option 'freq_value'    '4d81'  #350M
        #option 'chip_freq'     '350'
        option 'timeout'        '36'

Other config should have these settings:

config 'asic-freq' 'default'
        option 'freq_value'      '4f81'        #400M
        option 'chip_freq'     '400'
        option 'timeout'       '35'

To modify an area use the arrow keys.  Once you are in the text field area hit delete  to delete or insert to type text.
Once you are done modifying the config tap the escape key.
then type  ":x" to save and quit
if you screwed up the config just type
":q!" to quit without saving.
reboot miner after settings are in place.

finlof, greaterninja thanks! you guys are awesome!

I am testing 425 mhz...most I have gotten is 225 GH/s so far.  It does not seem stable and the damm thing was beeping at me for 2 minutes.  Live and learn right?
