Dude, I’m probably not getting this Dell.
It’s hard to argue that there are a terribly large number of people that replace the components in their laptops; they’ll typically leave them stock. And they’ll do so either until something needs repairing, or they simply get a new one. Ah, the Apple mindset.
Anyway, if you were planning on getting Dell’s Precision 7 series laptops with an eye towards upgrading that ram, well, you’re out of luck.
You are stuck with a proprietary module that provides you with 128GB of DDR5-4800 memory via CAMM (Compression Attached Memory Module). It can’t be swapped out for anything else.
That said, this is a laptop, and there are reasons for this (there wouldn’t be if it was a tower). For one, it saves on some valuable real estate inside the case. The two SO-DIMM slots that would normally be used are replaced by a single part that does everything they did. It also helps make the unit lighter, which is a good thing for something that’s supposed to be portable.
It also, however, locks users into Dells CAMM ecosystem. Which, depending on how they play things, could either be good or bad. If it’s opened up to other manufacturers, it could be the sort of thing that makes future laptops the beneficiaries of the value the module provides. Right now, though, it locks users into dealing with Dell for any upgrades to that part of their laptop. It’s a matter of how things go, really.
