Sir,
Mmm, it did run on my dual 3.20 Ghz, 1 terabyte, 7 GB RAM paper weight. With
your specs, you shouldn't have a problem unless your RAID is
misconfiguration, what is the I/O per second request count and CPU % use
before kernel shut down.

I ran the equation on a 2Ghz G5 with 6 GB ram and received the error
message:  no more memory available.  Mathematica kernel has shut down. 
Regards.
