16gb of ram detected out of 32gb

[gnulab]

Hi,

I'm using centos 6.2, kernel 2.6.32-220.7.1.el6.i686 on the IBM x3400 server.

CentOS only detects 16gb of ram, while the bios has detected the 32gb of ram alright. I read that it is due to 32-bit version of the OS, but my kernel is already 64bit (i686).

So, how can I have CentOS correctly detect 32gb of ram?


Thx.
Henry

Run the 64 bit edition not the 32 bit one. The 32 bit version is limited to 16GB RAM as detailed in https://access.redhat.com/articles/rhel-limits

Also, please please don't run 6.2. It's massively out of date, riddled with serious security vulnerabilities and a complete liability. You should yum update and get current which is 6.7 at the moment.
