Step 3. Configure Memory
Your board comes with three DIMM sockets, providing support for up to 256MB of main
memory using DIMM modules from 8MB to 128MB.
Memory Configuration Table
Number of
Memory Modules
DIMM 1 DIMM 2 DIMM 3
1 Double-sided/Single-sided Double-sided
2
Double-sided/Single-sided Double-sided
3 Double-sided/Single-sided Single-sided Single-sided
RAM Type SDRAM
Memory Module Size (MB)
8/16/32/64/128 Mbytes
Note:
Because DIMM banks 2 and 3 are shared, double-sided DIMMs
(having ICs on both sides of the module) can be used in only one of
the banks. With single-sided DIMM both bank 2 and 3 can be used.
Step 4. Set JP9 for power up FSB clock and AGP bus clock.
JP9 is used to adjust AGP bus clock frequency depending on the value of the front side bus
(FSB) clock, also the setting of the JP9 determines the power up FSB clock which will
remain effective until the BIOS set the FSB clock to the CMOS setting.
JP9 Setting
Power up FSB Clock 66MHz 100MHz
AGP Clock
AGP Clock = FSB Clock ÷ 1 AGP Clock = FSB Clock ÷ 1.5
Note: The specification of maximum AGP bus Clock frequency is 66.6MHz.
∗
Set JP9 to pin 1-2 short when you use a FSB 100MHz CPU.
∗
Set JP9 to pin 2-3 short when you use a FSB 66MHz CPU.
∗
Set JP9 to pin 1-2 short when you use a FSB 66MHz CPU but want to over clock the
FSB clock to 100MHz via the BIOS setting.
Step 5.
Set the CPU Frequency
You do not need to set any jumper for the CPU frequency. Instead, CPU settings are
changed through the BIOS
[SOYO COMBO SETUP].
Please refer to Chapter 3 - Quick
BIOS Setup for details on how to set the Celeron
processor frequency.
