In a P3 RAMBUS system, RDRAM modules of different capacities are allowed, e.g.
128MB & 256MB. In a P4 system, they are allowed, too, as long as the rule of
matched pairs is adhered to, much like the classic Pentium motherboards with
72-pin SIMMs.

But I cannot mix memory moduals of different capacity, right? For
example, I could not leave the existing 128MB modual, and replace the
CRIMM with a 256MB modual?
