O200 PIMM-modules and MB are connected in the sense that the MB needs to know the base clockspeed of the PIMM-module, which you need to flash by hand while the system is still running with the original CPU-MB combination. If you exchange PIMM modules without updating the clockspeed info on the MB, you risk bricking it.
Oh, and steer clear of R12K 270MHz, these are particularly problematic.
BTW: thread necro
Even when the clockspeed is the same and the difference is just the number of CPUs on the PIMM?
If you're in doubt what topics fit then check the discussions of the last year or two ...
