III. INSTALLATION

DIMM Memory Installation Procedures:

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. DRAM

SIMM modules have the same pin contact on both sides. SDRAM DIMM modules

have different pint contact on each side and therefore have a higher pin density.

The Dual Inline Memory Module (DIMM) memory modules must be 3.3Volt Un-

buffered Synchronous DRAM (SDRAM) or Extended Data Output (EDO) . 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 to be inserted into the DIMM slot on the

motherboard. You must ask your retailer for the specifications before purchasing.

Four clock signals are supported on this motherboard.
