3.5.2 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 shown. DIMM mod-
ules are longer and have different pin contact on each side and therefore have a
higher pin density. SIMMs have the same pin contact on both sides.

The notches on the DIMM will shift between left, center, or right to identify the type
and also to prevent the wrong type from being inserted into the DIMM slot on the
motherboard. You must ask your retailer the correct DIMM type before purchasing.
This motherboard supports four clock signals per DIMM slot.
