3.4. DRAM INSTALLATION
The mainboard can be installed with 8 / 16 / 32 / 64 / 128 / 256 MB 168 pins
DIMM module DRAM, and the DRAM speed must be 50 or 60 ns for EDO &
67~100 MHz for SDRAM. The DRAM memory system on mainboard
consists of bank 0, 1, 2 & bank 3.
Because the 168 pins DIMM module is 64 bits width, using 1 PCS which can
match a 64 bits system. The total memory size is 8 MB ~ 1 GB EDO or
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 couldn't be inserted into
socket completely.
