Um, aren't memory modules the commodity product that is in short supply?

Recycling the broken ram sticks isn't done as far as I know so it kinda makes sense. New memory and used working sticks is hard to get. Broken sticks most likely not so hard.

I thought part of the reason for increased ram prices was a shortage of chips and not the assembly of ram modules

Not a terrible idea if you have a good process. Not sure my hand is steady enough to do it without a bga machine, but solder paste, custom masks, and a diy rig for lowering the chip could possibly do it.

TL;DR: It isn't cheaper to get it these ways than by buying them.

I havnt read it but if there is a shortage of specifically memory modules arent the modules still going to cost a ton?

linux users are one production step closer to just mining lithium themselves.
