LinuxQuestions.org - Latitude E4200 - dmidecode --type 16 --type 17 maximum RAM

Hi,

looking on purchasing more RAM memory for my E4200
and all websites supplying RAM for my type of laptop
advise that it is only capable of taking 4GB in that
1 bank it has got plus 1GB which is on board, but
when looking at sudo dmidecode --type 16 it says:
Maximum Capacity: 8 GB

sudo dmidecode --type 16 --type 17
# dmidecode 2.11
SMBIOS 2.4 present.

So looking at PC3-10600 DDR3 SDRAM SODIMM 204pin memory, it is only sold
in 4GB and 8GB sizes, noting between, if it says Maximum Capacity: 8 GB,
does the figure includes the 1GB on board RAM as well so I would ideally need 7GB RAM,
or is it 8GB max in the memory bank?

Has anyone tried 8GB RAM, or will it work?
