The only place where faster rates are desirable is when gyros are used with digital servos to stabilize a vehicle. Many upper-end gyros will produce faster position pulses so that the servo can react faster to external influences such as wind. If the gyro is set to provide pulses at 150Hz then the servo will begin to respond to external influences 3-times faster than it would at 50Hz. The fact that the receiver only provides position pulses at 50Hz does not prevent the system from responding quicker to gyro inputs. This faster response time can make a big difference in control system damping and can often avoid oscillation and other adverse effects associated with slower sensory input.

Only use output frequencies faster than 50Hz when a sensor such as a gyro is plugged into one of the SM2 inputs, and the sensor is capable of updating and posting position pulses faster than 50Hz. Set the output frequency to at least match your sensor output, preferably a little faster. Make sure your servo can handle the higher rate by checking the servo specifications. Test the servo operation  by setting the output frequency on the SM2 Control Panel Application and using the "Program Device" function to set the output frequency on the SM2. The output frequency cannot be simulated so you must program the device to test different settings. 

Use the "Output Frequency" slider bars to set the rate at which the position pulses will be sent from the SM2.

A warning note will appear on the SM2 Control Panel Application if the output frequency is set much higher than 50Hz to make sure the operator understands that some servos may not work.
