Hello
I have 8GB of RAM however /proc/meminfo only gives me 4GB.
Anybody know why ?
is it because the other 4GB is not recognized or limitation with /proc/meminfo or wrong command ?
anyother command line I can use ?

Just guessing here, but you may need to recompile your kernel to enable High Memory Support (under the Processor Type and Features section). I know there is a 4G option, and there may be a 64G option. If so, enable 64. I'm not at a Linux box right now so I can't verify this myself, but I'd suggest it would be a reasonable first place to look

As per J.W., to see what you currently have configured, try something like
