Step 3. Configure Memory

Your board comes with three DIMM sockets, providing support for up to 512MB of main memory using DIMM modules from 8MB to 256MB.

Note: Because DIMM banks 2 and 3 are shared, double-sided DIMMs 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.

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 2-3 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.
