We are having a connection problem trying to connect a BlueRov2 with a FathomX on the QGC.  
QGC requires at least 8GB RAM and we are running it in a laptop with 4gb RAM, could this be the problem?

If it’s not connecting I’d recommend you go through our [troubleshooting steps](https://www.ardusub.com/reference/troubleshooting.html#no-telemetry--waiting-for-vehicle-connection-no-autopilot-connection).

Those requirements are to ensure reasonable performance levels. You may have issues with _poor_ performance (especially with the video stream), but I would expect it should at least be able to connect to the vehicle.
