WIN 10 64 bits 6 AMD gpu MSI R9 390x

How can I setup the overclocking settings?
I have wrote the following:
corefreq =       ["1150", "1150", "1150", "1150", "1150", "1150"];
memfreq =        ["1525", "1525", "1525", "1525", "1525", "1525"];
powertune =      ["50", "50", "50", "50", "50", "50"];
fanspeed =       ["90", "90", "90", "90", "90", "90"];

But the settings are not being read as it shows -1, Please Hep me
