CentOS - Feb 2011 - How much maximum memory will CentOS 5 support? I know it's not 16 GB!

How much maximum memory will CentOS 5 support, please?

The product info page at http://www.centos.org/product.html
says 16GB, but I am running 80 GB RAM right now and seeing
80 GB in top.

I see the same 16 GB limit on the RHEL page:
http://www.redhat.com/rhel/compare/#note_4

The server hardware is capable of 192 GB RAM and I want to
add memory, but want to be sure the OS will support it.

Is anybody running CentOS 5 or RHEL 5 with 192 GB or more, please?

Best,

You're looking at the 32bit limits :)

The 64bit  can support 256GB/1TB limit
