Antminer schedule auto change Frequency fan speed

[bittalc1]

Hi guys

i wanted to share my setup for automatic change fans speed, frequency and possible voltage but the newest firmware for the S4 does not allow the voltage change and its stuck on 0725v.

So i have created batch file that executes in the morning to slow the fans down and downclock the frequency 187.5Mhz of my miners, and also created another batch file that executes around 17h to bring them back to normal fan mode and frequency to my choosing.

For this setup the following files are required.
1. PSCP (an SCP client, i.e. command-line secure file copy) http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
2. Plink (a command-line interface to the PuTTY back ends)  http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
3. Task Scheduler      you can use the windows version or the no installation file from freebyte  http://www.freebyte.com/fbtaskscheduler/
4.WinScp

At first i set the required voltage and frequency on my miners and after that downloaded the cgminer.sh from /etc/init.d/    and cgminer.conf from /config   and i made separate folders for every miner and put the files there.

After that i downclocked all the miners to 187.5Mhz and 0700v and also made separate folders for my slow configuration  and downloaded and saved the files there (cgminer.sh and cgminer.conf) and edited the cgminer.sh to add the --bitmain-homemode  option to slow the fans.

i also created commands.txt so i can work batch commands through pscp, in this file i put only the cgminer restart line (/etc/init.d/cgminer.sh restart)

Sometimes i must hard restart a miner because it hangs when changing back to normal but its not happening always i think its because of changing the frequency, or maybe i should  use reboot command instead of cgminer restart. -- suggestions are welcome

In the end i put the slow.bat and normal.bat in task scheduler and choose the time when to execute.

So here is the slow.bat

Wow!

Let us know how it perform after few days or week!  Keep us updated!

Cheers!

I was looking for something like this for a while ... Great work. How do you save a copy the cgminer.sh cgminer.conf to your local drive ? What is the SHH command

Thanks

[notlist3d]

Very very impressive.  Nice job writing some batch files!

Sounds like a great idea.

[bittalc1]

Thanks guys. Btw you can copy the files with Winscp.

[adaseb]

Yeah thanks for posting this. This might come handy this summer with the heat.

[n200UG]

Thanks for the info. Did you ever found a fix for the hanging at time? I'm also getting a few system hanging after the batch run. I was reading about about bitmain-homemode to slow the fan. Which file need editing for this ?

Cheers
