Depends on how they'd be affected by the timing constraints - I've never
(yet!) tried a 450 Mhz module in an Ultra 2.

There isn't a jumper setting to correctly set the clock divisor for 450 Mhz
modules, but 450's will work fine in Ultra 60's and 80's (and the other
systems built around the U60 and U80 system boards) so they're useful to
have.

You could try a 450 Mhz module with each of the jumper settings for J2301 on
the Ultra 2 system board and see what happens. If you get a combination
which works the CPU might not run at the full rated speed.

Good luck!

Regards,

Craig.

don't do it, over 400mhz is buggy

How so? This is a play-around-with box as opposed to a mission-critical
server, so if it means a crash a couple times a year I'm not too worried

Looks like you wanted it more than I did
