Hi,
i have just installed 4 gb RAM ddr3 on OS Windows 7 32 bit.
In "manage peripherals" i see this section:
Memory installed (ram) : 4,00 gb (2,30gb usable)
Why only 2,30 gb usable ?
In Windows 7 32bit the maximum size is not 3,00gb ?
see file attached, please
Probably due to integrated graphics.
Why ?
Heard of Google?
Because it has to share memory with the CPU so as to; 1) function correctly and 2) increase graphics performance.
On_(mother)_board graphics is generally very limited and any help is welcome hence memory sharing...
This explains it better than me:-
