CGTune

CGMiner tuning software.

Download Link: CGTune.zip

CGTune is a freeware utility to modify CGMiner settings on the fly without shutting down and restarting the application. It can be used in scripts, batch files, and task schedulers. CGTune can be used to adjust the GPU engine, fan, voltage, memory settings, change intensity, disable/enable GPUs or completely shut down CGMiner to allow a end user to work on their computer or a home user to sleep at night.

It is not recommended that you use this with other CGMiner monitoring tools as they may conflict.

Installation

To install, first you will need to setup CGMiner to allow API calls. You can either add the following command line parameters to CGMiner:

--api-listen --api-allow W:127.0.0.1

Or if you are using a configuration (.conf) file, add the following lines:

"api-listen": true,

"api-allow": "W:127.0.0.1"

Note: The last line in the configuration must not contain a comma, but all the other lines before it must have a comma to separate each setting.

Command Line Parameters

Note: CGTune requires that all commands parameters use two dashes.

Example Commands

Adjust GPU (video card) to a clock speed of 850 MHz and set intensity at 18:

CGTune.exe --gpu-engine 0,850 --gpu-intensity 0,18

To adjust the two GPU (video cards) to a clock speed of 500 MHz and set intensity to 13:

CGTune.exe --gpu-engine 0,500,1,500 --gpu-intensity 0,13,1,13

To turn off the GPU (but leave CGMiner running) to allow system to cool down and user to work with computer for other tasks:

CGTune.exe --gpu-disable 0

Same as above, but turning off the six GPUs, CGTune supports up to 32 GPUs per command parameter:

CGTune.exe --gpu-disable 0,1,2,3,4,5

Known Issues

1. Shutting down all GPUs for a long period (30+ minutes) may cause CGMiner to become unresponsive. It's best to either use --quit to end CGMiner and unload it from memory or lower the GPU engine (use: --gpu-engine 0,500) and intensity (use: --gpu-intensity 0,8).
