We investigate the validity of generalized second law of thermodynamics of a physical system comprising newly proposed dark\nenergy model called Ricci-Gauss-Bonnet and cold darkmatter enveloped by apparent horizon and event horizon in flat Friedmann-\nRobertson-Walker (FRW) universe. For this purpose, Bekenstein entropy, Renyi entropy, logarithmic entropy, and power law\nentropic corrections are used. It is found that this law exhibits the validity on both apparent and event horizons except for the\ncase of logarithmic entropic correction at apparent horizon. Also, we check the thermodynamical equilibrium condition for all\ncases of entropy and found its vitality in all cases of entropy.
