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. SIMM modules have the same pin contact on both sides. DIMM modules are longer and have different pin contact on each side and therefore have a higher pin density.

The notch on the DIMM module will shift between left, center, or right to identify the type and also to prevent the wrong type of DIMM to be inserted into the DIMM socket on the motherboard. Four clock signals are supported on this motherboard. You must ask your retailer for the specifications before purchasing memory modules.
