Aims. We studied the correlations between spin frequencies and kilohertz quasi-periodic oscillations ( kHz QPOs) in neutron star low-mass X-ray binaries. Methods. The updated data on kHz QPOs and spin frequencies are statistically analyzed. Results. We find that when two simultaneous kHz QPOs are present in the power spectrum, the minimum frequency of upper kHz QPO is at least 1.3 times higher than the spin frequency, i. e. nu(s) = -( 0.19 +/- 0.05)nu(s) + ( 389.40 +/- 21.67) Hz. If we shift this correlation in the direction of the peak separation by a factor of 1.5, this correlation matches the data points of the two accretionpowered millisecond X- ray pulsars, SAX J1808.4- 3658 and XTE J1807-294.
