I understand that some types of RAM need to be installed in matched pairs if more than one. As a general query, why is this, and what is the likely effect of installing two modules of exactly the same memory type that are not matched? Just curious. Thanks in advance for any feedback. Steve

For standard set ups (not overclocked) it is usual to use matched pairs of RAM where the motherboard supports

Sorry hit wrong button! To continue it is usual to use matched pairs where Mobo supports dual memory. In such a set up the the processor is able to address both sticks simultaneously rather than in sequence which would give a better response time (up to approx 20% but not in practice twice as fast as is sometimes claimed).

For overclockers where they are are trying to sqeeze the last ounce of bandwidth by trial and error, it helps to have the RAM synchronised to start with.
