I rebuild my kernel 4.10.0-22 (ubuntu 17.04) and patched radeon driver=20
(atombios_crtc.c)
void radeon_atom_disp_eng_pll_init(struct radeon_device *rdev)
{
        /* always set DCPLL */
rdev->clock.default_dispclk =3D 62500;
        if (ASIC_IS_DCE6(rdev))
...

144Hz is working fine with this patch.=20
(Forcing dpm state high =3D perfect image / low or auto =3D bad flickering)=
=20
But Great improvement so far! Thank you.
