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 Dual Inline Memory Module (DIMM) must be 3.3V Unbuffered for this moth-

erboard. You can identify the type of DIMM module by the illustration below:

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.
