Question

Iron

Colleagues, help me unravel)
I have an HP ProBook 440 G4 laptop, the memory costs 16GB. I thought it was the maximum. And then I came across an info that you can install 32 and 64 GB. : https://www.compuram.biz/memory/hp-hpe/notebook/pr...
But it’s somehow incomprehensible, and, alas, I can’t understand on my own, so you can put 32 or 64 or not .... .

Answer 1

You buy the required amount of memory in a decent store, you check it at home.
Earned - rejoice, not earned - within 14 days you return back.
As an option - come to the store with a beech and ask on the spot to pick up a memory for you that will start in it.

Answer 2

The HP website says 16 is the maximum, there's no reason not to trust them.

Answer 3

According to your link at the very top of the table there is an explanation of such a discrepancy from the authors of the site. The situation they describe is theoretically possible. But in practice, if I really wanted to expand, I would try to get memory for tests and check everything myself. There are different options - buying with the possibility of a return, contacting a service center, friends, acquaintances, etc.
