Introducing Mainboard
1.2 CPU/memory
The mainboard supports Intel
®
Pentium
®
4 processors in the 478-pin
package. The mainboard uses a CPU socket called PGA478 for easy CPU
installation. When you are installing the CPU, make sure the CPU has a heat
sink and a cooling fan attached on the top to prevent overheating.
The mainboard provides 2 slots for 184-pin DDR SDRAM DIMM (Double
In-Line Memory Module) modules and supports the memory size up to 2GB. You
can install PC2700/DDR333 or PC2100/DDR266 modules into the DDR DIMM
slots (CN28/26).
Overheating
Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is
similar to conventional SDRAM, but
doubles the rate by transferring data twice
per cycle. It uses 2.5 volts as opposed to
3.3 volts used in SDR SDRAM, and requires
184-pin DIMM modules rather than 168-
pin DIMM modules used by SDR SDRAM.
High memory bandwidth makes DDR an
ideal solution for high performance PC,
workstations and servers.
