Proviso:

SS10 mem kits may be 80ns instead of 60.  This can cause problems on later
machines.

Some _third party_ SS10/SS20 memory kits used a memory refresh scheme that
doesn't play nicely with the Ultra memory controllers.  I doubt there are
too many of these around, but I have a box of 32MB DIMMs with exactly this
problem that are useless on anything post-SS20.

Some require quads.  Some get better performance with quads (the U30 can
interleave, for example).  Some get even better performance with sets of 8
or 16 (420/450) with more than 2 CPUs in a system.

I actually do agree.  It's a shame that Solaris x86 will probably never
see its full potential due to political issues within Sun.
