3.5.2 DIMM 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. DIMMs are
longer and have different pin contacts on each side and therefore have a higher pin
density compared to SIMMs.

The DIMMs must be 3.3V "registered" for this motherboard. To determine the DIMM
type, check the notches on the DIMMs (see figure below).
The notches on the DIMM module 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 pur-
chasing.
