Two things:
1) Ultra 30s don't use UltraSPARC-IIi processors... they use normal
UltraSPARC-II processors. (There was a pretty good deal of a U30/300
with 512MB of RAM on ebay from Sun for $1600, too.)
2) Mbus is a SuperSPARC/HyperSPARC, SS10/SS20/etc. thing
I heard of people overclocking machines while I was working at Sun... I
never looked too much into it, though.
