3.5.2 Memory Installation

WARNING! Make sure that you unplug your power supply when adding or

removing memory modules or other system components. Failure to do so may

cause severe damage to both your motherboard and expansion cards (see 3.3

Hardware Setup Procedure for more information).

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. DRAM SIMM

modules have the same pin contacts on both sides. SDRAM DIMMs have different

pin contacts on each side and therefore have a higher pin density.

The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type,

check the notches on the DIMMs (see figure below).

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 tell your retailer the correct DIMM type before purchasing.

This motherboard supports four clock signals per DIMM.
