40GB of RAM shown as 33GB in /proc/meminfo
My blade server has 40GB of memory installed. I could even verify and confirm it in the server inforfation through the enclosure onboard administrator,
but when I execute cat /proc/meminfo in my RHEL5, it gives me only 33GB as total memory.
Please Advice,

Check with free command
e.g:
# free -g
Shows memory in GB.
Cheers

uname -a
It is always helpful in these situations to know if we are dealing with a 64 bit or a 32 bit kernel.
also please post the free command output
