The energy band with detectable kHz QPOs is studied for the first time: on the horizontal branch, it is $\\sim$ 6.89--24.01 keV and $\\sim$ 8.68--21.78 keV for the upper and lower kHz QPOs detected by $RXTE$, and $\\sim$ 9--27.5 keV for the upper kHz QPOs by $Insight$-HXMT; on the lower normal branch, the energy band is narrower.
