Calculation of thermodynamic functions of the three-dimensio\-nal Ising ferromagnet above and below critical temperature is performed in the approximation of sixfold basis distribution (rho^6 model). Comparison with the results for the rho^4 model indicates that dependence of the thermodynamic functions on the renormalization group parameter $s$ becomes weaker. The optimal interval of the renormalization group parameter values is determined.
