Impossible. :-) The fastest Opteron right now is 2.5 GHz.

You probably want to use the Linux 'i386' JDK.

An Opteron runs all code faster MHz to MHz compared to Xeon. Opteron
has a shorter pipeline and thus can do more work per cycle. Xeon has a
very deep pipeline and thus can be clocked higher and must be clocked
higher to get the same performance.
