Linux Mint Xcfe only sees 4gb of RAM with 12gb installed
As in title but for some extra details-
The device I'm using was originally windows, and the windows 10 task manager saw all 12 GB before I installed Linux, and the bios sees all 12.
I'm aware that 32bit systems can't accept more than 4 but my device is definitely running 64bit (uname -m comes up with x86_64)
I'm also aware that integrated graphics takes some ram but even then i would assume it should say how much it's taking (or maybe not, this is my first time installing Linux, maybe I'm just misunderstanding the task manager after almost 20 years of windows)
Any help appreciated.
Edit:
I quickly did a Sudo dmidecode -t memory and it does show each of the installed sticks, so I really don't know why Linux isn't using them.
