OK, so I finally got it sorted. It all depends on the bootloader I use.
As I have a dual boot with Windows 10, I have two boot scenarios.
I can either go through the bootloader that came with Kali (my usual option until now). In which case, for some reason, the full amount of installed RAM is not recognized in Kali after boot.
I can also use the Windows bootloader, in which case all RAM is recognized when Kali boots.
So this second option will now be my preferred option to start Linux.
It's actually a bit more complex than that but I won't bore you with the details, unless you are interested in which case I can do a short write-up here. Just let me know.
Anyway, I want to thank all of you for the time you took to help me out. You got me on the right track so thanks a heap for that!
