Connect the CPU Cooling Fan
power cable connector to the
CPUFAN connector.
Notes:
•
To achieve better airflow rates and heat dissipation, we suggest that
you use a high quality fan with 4800 rpm at least.
•
CPU fan and heatsink installation procedures may vary with the type of
CPU fan/heatsink supplied. The form and size of fan/heatsink may also
vary.
Installing Memory Modules
This mainboard accommodates 184-pin 2.5V Double Data Rate (DDR)
SDRAM and 168-pin 3.3V SDRAM memory modules. The memory chips must
be standard SDRAM (Synchronous Dynamic Random Access Memory).
The CPU supports 100MHz system bus. The SDRAM DIMMs and DDRs can
synchronously work with 100 MHz or operates over a 133 MHz system bus.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the mainboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
Installation Procedure
You must install at least one memory
module in order to use the main-
board. Each module cab be installed
with up to 1 GB of memory; total
memory capacity is 2GB.
Note: You cannot use DDR
SDRAM and SDRAM
simultaneously.
SDRAM provides 800 MBps or 1 GBps data transfer depending on whether
the bus is 100 MHz or 133 MHz. Double Data Rate SDRAM (DDR SDRAM)
doubles the rate to 1.6 GBps or 2.1 GBps by transferring data on both the
rising and falling edges of the clock. DDR SDRAM uses additional power and
ground lines and requires 184-pin DIMM modules rather than the 168-pin
DIMMs used by SDRAM.
