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 Linux domain.com 2.6.18-8.1.10.el5 #1 SMP Thu Aug 30 20:43:15 EDT 2007 i686 i686 i386 GNU/Linux # dmesg|grep mem Memory: 3758888k/4194304k available (2043k kernel code, 39868k reserved, 846k data, 232k init, 2882432k highmem) Freeing initrd memory: 2239k freed highmem bounce pool size: 64 pages Total HugeTLB memory allocated, 0 Non-volatile memory driver v1.2 Freeing unused kernel memory: 232k freed ehci_hcd 0000:00:1d.7: irq 225, io mem 0xee000000 Thanks in advance for any help.
