Step 3. Configure Memory

Your board comes with three DIMM sockets, and provides support up to 512MB main memory using PC100 DIMM modules from 8MB to 256MB.

Note: 1. PC100 Compliant DIMM module is required regardless of 66 or 100 MHz FSB speed.

2.If you want to use DIMM3, DIMM2 must be used as well to let the system work properly. Just plugging a memory module into DIMM3 with DIMM2 left empty, will make the system not working.

Step 4. Set J6 &JP2 to configure CPU FSB Frequency

If the user wants to use the CPU at its standard FSB (Front Side Bus) Frequency, J6 has to be closed. This will make sure the system will provide the CPU with the FSB Frequency it was specified to run at. Make sure that JP2 is open when using this setting.

If the user wants to run the CPU at another (higher) FSB frequency however, J6 has to be open. In this case use JP2 to set the FSB frequency.

Description

Run the CPU at its specified FSB frequency. For 66MHz FSB CPUs 66/75/83 MHz can be selected in the BIOS.

For 100MHz FSB CPUs 100~133MHz can be selected in the BIOS.

Note: Don’t put any jumper on JP2 when J6 is set to short.
