No, you don't actually. I've run my E3000 with a board that just has
memory on it before (it was an older board that only supported 167's,
and I've upgraded my system to have 336s).

That is correct

Beware that if you mix processor speeds, all the processors will run at
the slower speed (250MHz in your case).
