[Ham-Linux] linux and ram

[Mike McCarthy, W1NR]

If you have recent hardware that supports PAE (Physical Address
Extensions) and a recent Linux distribution that has a PAE version of
the kernel available, you can see at least 8GB as that is what I see
running openSUSE 11.1 on my current system, which has an Athlon 64 X2
with 4x2GB memory sticks.  PAE is supposed to allow 64GB with a 32 bit
kernel.  Processes are limited to 2GB each in a 32 bit OS.  Red Hat
Enterprise recommends using a 64 bit kernel for 16GB and above.

Not really aware of the issues with applications on 32 bit vs. 64 bit.
