You can't change the "nodes" since that is defined as 2 by having dual core
opterons.

What you can change is whether memory pages are interleaved (commonly called SMP
in the BIOS) as opposed to each node having one large block of contiguous memory
(commonly called NUMA in the bios settings).  You want "NUMA"  If you have 8
gigs of ram, this will put the first 2 gigs on node zero, next 2 gigs on node 1,
etc.  Otherwise page zero goes on node 0, page 1 on node 1, etc, which is not
what you want...
