SOYO SY-7IZM quick start Set JP9 for power up FSB clock and AGP bus clock, Configure Memory

SY-7IZMQuick Start Guide

Step 3. Configure Memory

Your board comes with two DIMM sockets, providing support for up to 256MB of main memory using DIMM modules from 8MB to 128MB with no restriction on memory configuration. Therefore, you can install memory modules in any combination.

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		3		3
		2		2
		1		1
Power up FSB Clock	100MHz		66MHz
AGP Clock	AGP Clock = FSB Clock ÷ 1.5		AGP Clock = FSB Clock ÷ 1

Note: The specification of maximum AGP bus Clock frequency is 66.6MHz.

∗Set JP9 to pin 2-3 short when you use a FSB 100MHz CPU.

∗Set JP9 to pin 1-2 short when you use a FSB 66MHz CPU.

∗Set JP9 to pin 2-3 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

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.
