I have an 8GB RAM System but Ubuntu 12.04 only detect 4GB by system start. Every time I reboot the System Ubuntu will detect the full 8GB RAM!?!?!?

You need to run 64bit Ubuntu to address more than 4GB of ram.
I think you installed the 32bit version with the pae
kernel. Enter in the terminal:
uname -a
If you see pae
mentioned or i386
, you are using the 32bit version.
To use the full amount of RAM you need to install the 64bit version.
free -m
by editing your Qn.uname -a
anddpkg -l | grep linux-generic
