Two methods of mass calculation of degenerate dwarfs were considered: based on (1) hydrostatic equilibrium equation as well as (2) variational principle. In this work we used model with ideal electron subsystem and one with Coulomb interaction. An instability region of massive white dwarfs was explored. For the first time, taking into account the Coulomb interaction, there were obtained critical values of mass and relativistic parameter at wich instability due to general relativity effects occured.
