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 Module Size (MB)

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 JP45 for power up FSB clock and AGP bus clock.
JP45 is used to adjust AGP bus clock frequency depending on the value of the front side
bus (FSB) clock, also the setting of the JP45 determines the power up FSB clock which will
remain effective until the BIOS set the FSB clock to the CMOS setting.
JP45 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 JP45 to pin 1-2 short when you use a FSB 100MHz CPU.
∗
Set JP45 to pin 2-3 short when you use a FSB 66MHz CPU such as 300AMHz,
333MHz, 366MHz, etc.
∗
Set JP45 to pin 1-2 short when you use a FSB 66MHz but want to over clock the FSB
clock to 100MHz via the BIOS setting.
Step 5. Set the CPU Frequency
This Motherboard does not use any jumpers to set the CPU frequency; CPU setting are
changed through the BIOS [SOYO COMBO SETUP]. Refer to Chapter 3 “Quick BIOS
Setup” for details on how to set the

processor frequency.
