The paper presents the new data of dielectric dispersion in DMAGaS crystal. The very pronounced dispersion above T_{c1} =136 K is observed in the frequency range 100 Hz-30 MHz with a single relaxation process. The relaxation time τ of an electric dipole reaches 2.17×10^{-7} s at the T_{c1}. The activation free energy ΔF of the dipoles is estimated to be equal to 0.087 eV. The order-disorder type of phase transition is confirmed.
