Hardware Installation

3.4. DRAM INSTALLATION

The Motherboard can be installed with 16 / 32 / 64 / 128 / 256 / 512MB (256Mb

Technology) 168 pins DIMM module DRAM, and the DRAM speed must be

67~100 MHz for SDRAM when system bus speed is set to 66MHz. When

system bus speed is set to 100MHz, 100MHz SDRAM is required. The DRAM

memory system on Motherboard consists of bank 0, 1, 2 & bank 3.

Since 168 pins DIMM module is 64 bits width, therefore 1 piece of DIMM

module may match a 64 bits system. The total memory size is 16 MB ~

1.5GMB(256Mb Techonloy) SDRAM, EDO DRAM size is 16MB ~ 384MB. The

DRAM installation position refer to Figure 3.1, and notice the Pin 1 of DIMM

module must match with the Pin 1 of DIMM socket. Insert the DRAM DIMM

module into the DIMM socket at Vertical angle. If there is a wrong direction of

Pin 1, the DRAM DIMM module could not be inserted into socket completely.

3.5. CPU SPEED SETUP

The system bus speed can be set for 66,100,133 MHz. The user can select the

system bus speed (SW2) and change the DIP SWITCH (SW1) selection to set

up the CPU speed for 300 - 866MHz processor.

The CPU speed must match with the frequency RATIO. It will cause

system hanging up if the frequency RATIO is higher than CPU's.
