To configure the speed and the voltage of the CPU, you must enter to the CPU SOFT
MENU in BIOS Setup, which is discussed in Chapter 3 System BIOS.
MEMORY MODULE INSTALLATION
When this main board was designed, we not only have taken into account the
economy and compatibility, but we also focused on the tremendous performance gain
by using SDRAM DIMM.
There are two 168-pin DIMM sockets on board. You may install up to two single
sided DIMMs on board. A total of 128MB system memory is supported.
The installation is easy. Simply push the two clips on the DIMM socket ends
outward, orientates the notches on the DIMM against the socket keys, and gently push
it down. Gradually increase the force you use, and make sure the clips are properly
snapped on the module. However, before you proceed with installation, be patient, first
following information carefully:
1. 168-pin DIMM modules specifications
According to the standards defined by JEDEC, there are different types of
specifications for 168-pin DIMM sockets. Here are the possible types:
•
3.3V UNBUFFERED DIMM
•
3.3V BUFFERED DIMM
•
5V UNBUFFERED DIMM
•
5V BUFFERED DIMM
Currently, the standard for PC is 3.3V UNBUFFERED DIMM, which is used by
this motherboard.
Since the connection between the socket and module is crucial, purchase quality
DIMM from a reliable source. The DIMM module board must have a thickness
of 1.27

0.1 mm. The Gold coating on the DIMM “Gold Fingers” must have a
thickness of 3 to 5 micron.
2. 60ns FastPage Mode or EDO DRAM DIMMs
If your memory modules are faster than 70ns, say 60ns or 45ns, you can modify
