* Somebody:

Re your statement about systems having more then 2 banks, which motherboards
support this? most of the motherboards I see have 4 slots... on occasion I
see a 6 slot motherboard, but its rare. I'm not sure how the slots are
divided up on those.

Mainstream (i.e. single CPU) ATX/BTX mobos usually have four memory
slots, Mini-ATX boards have usually two or three memory slots. Single
processor workstation and server boards usually have four to six slots,
and dual processor server and workstation boards usually have six to
eight memory slots.

The mobo in my main workstation for example has eight memory slots which
runs the memory in quad channel config.
