I would recomend not using these softwares most of them are spyware or adware or add some crap or they other to your computer
and they do all the other work but the ones they are supposed to do
once i ahd read somewhere that such softwares always gives some error regarding the uncompatibility with your computer but installs all they other crap so they get their a** saved because it was compatible
but their work was done anyways and all that was optoimised was their pockets
so well yeah go out and buy some ram better than download =ing such crap
