Can confirm. Happened to me with my old laptop. Tried to upgrade it with some rescued RAM and it refused to use all of it. It would only use up to the laptops advertised max.

(Not the brand in question, but motherboards can definitely limit the RAM utilisation)

And on this day, the term patriautism was coined

Woman has daughter. Woman marries man. Man and woman have son. I guess man and woman break up? Son has weekly visits to man, daughter of woman brings son to man. Or maybe son goes to boarding school or something 🤷‍♂️

That is the reasonable explanation. If you want to imagine the situation with a banjo soundtrack nobody is stopping you.

If you are looking for a distro similar to Arch where you can compile everything from source you can just use Arch. https://wiki.archlinux.org/title/Arch_build_system

Disclaimer: I have never used this feature so don’t know how easy it is to use, but I do use Arch which is how I know it exists. (I use Arch btw)

It’s not using Nvidia optimus technology is it? My old laptop had a GT 550M in an optimus configuration which made using linux tricky for quite a long time. Should be easier now i reckon though.
