Switch Radeon GPU: Restart GPUs and switch Polaris Compute Mode, Vega HBCC Memory and Large Pages
Updated on June 6th, 2018 to version 0.9.5

Switch Radeon GPU is a simple command line tool for restarting Radeon based GPUs. It can switch Polaris based GPUs (RX 470/480/570/580) from ‘Graphics Mode’ into ‘Compute Mode’. It also can toggle low level options of Radeon Vega GPUs like HBCC Memory and Large Pages support.

Switch Radeon GPU was developed as part of Cast XMR CryptoNight Miner but could be useful for handling Radeon GPUs for all sorts of workloads in OpenCL compute mode.

Make restarting your Radeon based GPU a breeze:

Switch Radeon GPU 0.9.5 for Windows (64 bit)
Restarts Radeon GPUs
Switch ‘Compute Mode’ on or off (only RX 470/RX 480/RX 570/RX 580)
Switch ‘HBCC Memory’ on or off (only Vega GPUs)
Switch ‘Large Pages’ on or off (only Vega GPUs)
Windows 8/8.1/10 64 bit
AMD Radeon RX Vega 56/64 GPU
or AMD Radeon Vega Frontier Edition GPU
or AMD Radeon RX 480/RX 580 GPU
or AMD Radeon RX 470/RX 570 GPU
Radeon Driver 17.1.1 or later for restarting GPUs
Radeon Driver 18.1.1 or later for switching modes
How To
switch-radeon-gpu has a command line interface:

switch-radeon-gpu [-G 0,..,N] [options] [restart|autorestart|fullrestart]

Executing switch-radeon-gpu without any arguments will list all installed Radeon GPUs and their status.

To select which GPU to operate on use the -G switch, e.g. for restarting the 2nd card use:

switch-radeon-gpu -G 1 restart

To select multiple GPUs use the -G switch and list comma separated the GPUs which should be used, e.g. for restarting the 1st and 3rd card use:

switch-radeon-gpu -G 0,2 restart

There are different restart modes:

restart fast restart the specified GPU, the AMD Radeon Settings will sometimes not pick up the configuration changes and display the old state
autorestart only restart the GPU if necessary due to a change in configuration
fullrestart a more sustained restart of the GPU, also the AMD Radeon Settings app wil restart
If no GPU is specified with the -G option all available GPUs will be restarted!

Following options of the GPU can be switched:

--compute =on switch the GPU based in ‘Compute Mode’ =off switch to ‘Graphics Mode’ (Polaris only)
--hbcc switch HBCC =on or =off (Vega only)
--largepages switch large page support =on or =off (Vega only). Most usefull for Vega Frontier Edition to better utilize the available 16 GB memory
For example switch all Polaris based GPUs to Compute Mode:

switch-radeon-gpu --compute=on autorestart

To turn HBCC Memory option for all Vega based GPUs to off:

switch-radeon-gpu --hbcc=off autorestart

To toggle Large Pages only for the 1st GPU to on:

switch-radeon-gpu -G 0 --largepages=on restart

For a complete list of configuration options run:

switch-radeon-gpu --help
