All GPUs in the sync boost group will boost to the minimum possible clocks across the entire group. Look at the throttle reasons for other GPUs in the system to see why those GPUs are holding this one at lower clocks. #define nvmlClocksThrottleReasonUserDefinedClocks nvmlClocksThrottleReasonApplicationsClocksSetting Deprecated Renamed to nvmlClocksThrottleReasonApplicationsClocksSetting as the name describes the situation more accurately.
