I am using Samsung 750 Evo 120GB. The problem is that after installing Samsung Magician 4.9.7 I cannot set the OS to Maximum Performance. It says "1. Failed to tune power options". In other words Magician`s not setting the power levels correctly. I have carried out a clean install to get any bugs out the system and they still won`t set correctly. Any suggestions please. Running Win10 32 bit. Thanks.
