Cgminer “rotate” command

Let’s learn about new command rotate.

–rotate # (there are two of – before rotate.)

# indicates minutes.
So, what this does is rotating mining servers. If you set –rotate 5, then rig will log in to 1st pool for 5 minutes then it will run 2nd pool after that.

You can use this command for you to compare different pools in given period of time without you trying to log in an out.

Cgminer failover only command in batch file

Time to time, your pool server goes out of service for maintenance or some other odd reasons. When you are not around there is no way to know and you don’t want to be around your rig all day long to change any settings. That’s is not passive income!!!

Well, here is the solution. Failover only command in batch file.

–failover-only -o stratum+tcp://NEW POOL URL:3333 -u user -p password

*There are two dash lines in front of failver-only. – – (Type two dash lines without space. I had to put space for you to see in this blog.)

Add this to the batch file that you are currently running. Whenever your pool server is down, it will automatically log in to other pool and start mining there until you restart your batch file to go back to your original pool. Yeah.. there isn’t cgminer setting that can detect server back in service and log back into original server again. At least that’s what I know so far. =p

It is confirmed that after 1st server is down, failover command automatically logs in to 2nd server then once 1st server is back up, failover command returns the log back in to 1st server.
Also, you can have multiple server listed with failover command.

Cgminer batch file set up for individual GPUs

This setting is ideal for testing each GPU and set to its maximum performance especially when each card is different brands/models/editions/etc.

For my example, I have 2 same FXF and 1 older version of FXF 7950s.

I made 2 batch files.
#1 miner_start0.bat
#2 miner_start1.bat

In miner_start0.bat, it’s designated for the older version of XFX. So, in the batch file I included -d 0. This isolates control of all but the card that is recognized as 0 on your motherboard.

In miner_start1.bat, it’s designaed for the 2 other XFX. So, in the batch file I included -d 1,2. This controls 2 other XFX cards at once.

If you run only miner_start0.bat file, you will see device 1 and 2 are shown “OFF”.

This is picture of my system running miner_start1.bat file with device 0 “OFF” and 1 and 2 are running.

If you want to control each GPUs separately, you can do so by putting -d # on each batch file.
