I gave up entirely on my Ender 3 pro. No amount of tweaking could get it to print more or less flawlessly every time. There was always an issue that needed tweaking every time I fired it up. Everything I changed to make it better only made it worse.
But somehow my newer Ender 3 S1 pro has been mostly flawless. Calibration has taken a while, but its built in bed leveling actually works. You’ll still need to do the initial leg work. But now that that’s done I just periodically run the bed leveling and mostly just fire it up, start a print, and let it go. I’m never again going to touch a custom firmware.
As you start getting closer to your memory limit windows starts unloading things. 11 on first startup will use like 4+ gigs, but only really needs about 2. I honestly have no idea what it’s doing with all that extra ram.
Disk caching isn’t counted in the ram used number task manager gives you so it’s not like that’s what it’s being used for.
