3.4. SRAM INSTALLATION
Sync. SRAM (Pipeline Burst SRAM)
If Sync SRAM Chip is installed, it consists of Pipeline Burst 1 Pc 64 K x 64 512KByte.
3.5. DRAM INSTALLATION
The mainboard can be installed with 16 / 32 / 64 / 128 / 256 MB 168 pins DIMM
module DRAM, and the DRAM speed must be 67~100 MHz for SDRAM. The DRAM
memory system on mainboard consists of bank 0 & bank1
¡ B
bank2 .
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 16 MB ~ 768 MB DRAM. 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
.
