Re: [CentOS] Adding RAM

...

I have a server running Centos 4.7 32bit. Will moving from 4Gig of RAM to 8Gig do any good? Since its 32bit I assume it will only be able to address the first 4Gig not?

As long as you are using a SMP kernel you can use up to 64GB of RAM (though each proccess can only address 4GB of this). So if you can find any trace of "SMP" in the uname (grep is your friend) then it should work fine.

I have this:

[root@srvr ~]# rpm -qa | grep kern kernel-smp-2.6.9-78.0.8.EL glibc-kernheaders-2.4-9.1.103.EL kernel-utils-2.4-14.1.117 kernel-2.6.9-78.0.8.EL [root@srvr ~]#

[root@server ~]# uname -a Linux XXX 2.6.9-78.0.8.ELsmp #1 SMP Wed Nov 19 20:05:04 EST 2008 i686 i686 i386 GNU/Linux
