The default IP address of the miner is 192.168.1.99,
[code][b]Username:root, Pwd:root[/b]
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.
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.
vim /etc/config/asic-freq
vim is a text file editor. The asic-freq file is opened now.
Type
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
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.
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'
