Re: [K12OSN] Server specs



Looks like your RAM is sufficient but the cpu count is low. If you can
toss a dual core into the box, that will be the good. If you can put in
a quad-core, even better. I'm unclear on the specs of the machine you
listed.

You will need to run the PAE kernel on the server to use the 8GB most
efficiently (I think that machine is 32-bit and not 64-bit). The 32-bit
systems can't address more than 4GB RAM directly and the PAE kernels
provide a workaround.
