7. 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 two 168-pin 3.3V and two 184-pin 2.5V un-
buffered SDRAM/DDR SDRAM (Double Data Rate SDRAM) memory modules.
SDRAM provides 800 MB/s or 1 GB/s data transfer rate corresponding with
the bus 100 MHz or 133 MHz. It doubles the rate to 1.6 GB/s and 2.1 GB/s 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 2.5V
unbuffered DIMM module rather than the 168-pin 3.3V unbuffered DIMMs
used by SDRAM.
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.
Note: You must install at least one memory module in order to work out this
mainboard, either SDRAM or DDR SDRAM, but you can’t use them
simultaneously.
Refer to the following to install the memory modules.
