DIMM Memory Installation

Insert the module(s) as shown. Because the number of pins are different on either

side of the breaks, the module will only fit in the orientation as shown. DIMM

modules are longer and have different pin contact on each side and therefore have a

higher pin density. SIMM modules have the same pin contact on both sides.

the motherboard. You must ask your retailer the correct DIMM type before purchas-

ing. This motherboard supports four clock signals.
