     When working for an Apple dealer I found that memory hogs (like 
HyperCard) tend to have problems with simms of different speeds .. I even 
had some Macs come in with the "Sad Mac" bootups and when running diags on 
them the problem turned out to be the simms (different speeds) .. Although 
I'm not sure if the simms went bad because of faulty manufacturing or 
becasue of the mix of speeds but to stay on the safe side I would recomend 
keeping the speed the same ..
