On desktops, I have seen problems (not direct experience) with getting full speed from 4x64gb ram sticks. Will 5600ddr 2x64gb sodims be stable on a budget (BOSGAME 7840hs) mini pc?

For use with LLMs, I doubt the 780m can have great (usable?) performance for models that would need 128gb (with context for coding). 96gb is decent price/size value. But is 64gb simply enough for what you would practically use?
