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		DIMM 1		DIMM 2	DIMM 3
Memory Modules
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	1	1
	2	2
	3	3
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.
