To get the faster duplex mode you must use memory modules in pairs. They

must be specially constructed to work in this mode. I don't know how they

are wired internally. So if you have 4 slots you must use two, paired

modules. If you fill an odd number of slots whether the module is a special

paired one or regular memory, the system reverts to simplex mode which is

slower.

Isn't there an issue with combining some fast and some slow on the same

machine?

For a given type of RAM the computer can always run the faster ones. Speed

just means that the module was selected out of a batch because it was able

to run at the higher speed reliably.
