Not all memory available

Not all memory available

2007-10-09       - By Steven Buehler

 Back
I have a server that had 2GB of memory on it.  I just up it to 8GB.  During
boot, it shows all 8GB, but my Redhat only shows 4GB.  I didn't install the
desktop version...as far as I know.  Is there something else needed to see
more then 4GB?

# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5 (Tikanga)

# uname -a

# dmesg|grep mem

Thanks in advance for any help.
