You mean different hardware, or OS? I previously added 4 GB to an identical server from the same vendor running CentOS 5 and it recognized full amount of RAM. _____

I have verified that the hardware supports at least 4 GB RAM. I added an additional 2 GB ram. However, issuing the various command to show memory available, it would only show ~2.5 GB. So, reading about the PAE kernel, I installed it via RPM and after rebooting, verified that the /etc/grub.conf file shows the PAE kernel first and the Default=0. When I run 'cat /proc/meminfo' and 'free -om', it still reports 2.5 GB. Can someone explain what is going on and what I should do, other than upgrading to a 64 bit system? I have done this same update on an identical server running CentOS 5 and it recognizes the 4 GB. I can provide output from any commands necessary. Just let me know.
