If you are running memory-intensive compute workloads on the DGX Station and are
experiencing performance issues, consider conserving GPU memory by reducing or
minimizing the graphics workload.
‣
To reduce the graphics workload, disconnect any additional displays you connected and
use only one display with the DGX Station.
If you disconnect a display from the DGX Station, the disconnection is automatically
detected and the display settings are automatically adjusted for the remaining displays.
‣
To minimize the graphics workload, shut down the display manager and use secure shell
(SSH) to log in to the DGX Station remotely.
