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:

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?
