SOYO SY-6IZA-NA quick start Set JP45 for power up FSB clock and AGP bus clock, Dimm

SY-6IZA/6IZA-NAQuick Start Guide

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	Hardware Installation
Note: Because	DIMM banks 2 and 3 are shared, double-sided					DIMMs
3		Double-sided/Single-sided			Single-sided	Single-sided
RAM Type					SDRAM
Memory Module Size (MB)				8/16/32/64/128 Mbytes
(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.

		3		3
JP45 Setting		2		2
		1		1
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 CeleronTM processor frequency.
