Mixing memory modules in Powermac G5
If I have both CAS3 and CAS4 RAM modules for the PowerMac, will the computer automatically use the lowest speed for both? They are both DDR2 PC2-4200 533Mhz but the CAS3 memory have faster timing.
If so, I should replace the factory-installed CAS4 RAM with the faster RAM.
Thanks in advance.

It's not going to make any significant difference what CAS level you choose.
Having enough memory to avoid the Virtual Memory penalty matters MUCH MORE than having too little of a more expensive memory choice.
Too little memory, and you will hit the "as fast as a HD" memory speed bump.
