3.4. DRAM INSTALLATION
The mainboard can be installed with 4 / 8 / 16 / 32 / 64 / 128 MB 72 pins SIMM
module DRAM, and the DRAM speed must be 60 or 70 ns.
The DRAM memory system on mainboard consists of bank 0 & bank 1. Each
bank consist of 2 PCs 72 pins SIMM module DRAM.
Because the 72 pins SIMM module is 32 bits width, using 2 PCs which can
match a 64 bits system.
The total memory size is 8 - 512 MB, and various configuration of DRAM types
in the following TABLE are for reference:
