Yeah if you want to waste your life to little benefit I guess.
I set Command rate from 2T to 1T if available and thats it. I never bother to test after. Why does anyone need to spend hours and hours testing their PC to go from 188FPS to 189FPS?
Tweaking ram is mostly wasting your time now. This isn't 2003 anymore IMO.
And who are you to determine what is a waste of time for someone else?
Why does it even matter if its not your own time. These post may be beneficial to others if not for you I wouldn't worry about it
