Overclocking GPU

You can overclock and undervolt your GPUs with a ClockTune tool. The tool will allow you to update different settings depending on your rig setup.

Nvidia, msOS:
Power limit (W)
Core Clock (+/- MHz)
Memory Clock (+/- MHz)
Fan speed (%)
AMD, msOS:
VDDC (mV)
VDDCI (mV)
MVDD (mV)
Core Clock (MHz)
Memory Clock (MHz)
Fan speed (%)
Nvidia, Windows:
Power limit (%)
Core Clock (MHz)
Memory Clock (MHz)
Fan speed (%)
AMD, Windows:
Power limit (%)
Core Clock (MHz)
Memory Clock (MHz)
Fan speed (%)

You can enter one value to the input field or multiple values which will represent values for different GPUs ordered by BUS ID. The divider is space.

Fan speed can be either set as a fixed value or as a fan curve with a target temp and fan max. and min. ranges.

You can save your favorite overclocking profiles and then apply them to your workers through "Worker config" section, on the worker's profile, to algorithms in profit switch, or to the config template.

Please note that ClockTune will work on Windows node only if you run MSI Afterburner. You don't have to change anything in Afterburner, just run it; all settings are controllable from your minerstat dashboard.

ClockTune troubleshooting

When you are overclocking or undervolting your GPUs, do it gradually. You are maybe used to some settings that you were using in other systems, but it is possible that exactly same settings won't give the same results. If this is the case, your hardware will show as undetected or rig will start crashing. That's why we suggest to slowly change the settings to find the right value. Everytime you save changes of your ClockTune profile, the rig that uses this ClockTune profile will automatically load new values.

msOS

In case your ClockTune settings are different than what rig actually uses and you are using mining OS, try the following:

  • mclock to load the latest ClockTune settings;
  • mrecovery to recover the ClockTune settings.

Windows

Make sure that you are running a stable version of MSI Afterburner. Currently, this is version 4.5.
