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 & bank 2. (
can't be installed at the same time if the DRAM is double side.)
Since 168 pins DIMM module is 64 bits width, using 1 PCS which can match a
64 bits system. The total memory size is 8MB ~ 256MB EDO / 256MB
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.
PIN 1 : LED anode (+)
PIN 2 : LED cathode (-)
