3.4. DRAM INSTALLATION
The main board can be installed with 8 / 16 / 32 / 64 / 128 / 256 MB 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 main
board consists of bank 0, 1& bank 2.
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 8 MB ~ 768MB
SDRAM. 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
