INSTALLATION
(System Memory)
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.
SIMM
modules have the same pin contact on both sides.
DIMM modules are longer and
have different pin contact on each side and therefore have a higher pin density.
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:
168-Pin DIMM Notch Key Definitions (3.3V)
DRAM Key Position
Voltage Key Position
Unbuffered
RFU
Buffered
Reserved
3.3V
5.0V
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.
