AFAIK, NO_HZ doesn't mean that the timer doesn't have a defined frequency:

                                                                                                                                                                                                  This option enables a tickless system: *timer interrupts* will                                                                                                                                     
only trigger on an as-needed basis both when the system is                                                                                                                                        
busy and when the system is idle.

1000_HZ and CONFIG_NO_HZ can happily be enabled at the same time.
