3.4. DRAM INSTALLATION
The mainboard can be installed with 8 / 16 / 32 / 64 / 128 / 256 / 512 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.
Since 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 ~ 2 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.
3.5. CPU SPEED SETUP
The system bus speed can be set to 100MHz. The user can change the DIP
SWITCH (SW) selection to set up the CPU speed for different processors.
The CPU speed must match with the frequency RATIO and Front Side Bus
(FSB) speed. It will cause system hanging up if the frequency RATIO and
FSB Speed do not match with the CPU.

The CPU is a sensitive electric component and it can be easily
damaged by static electricity, so users must keep it away from
metal surface when the CPU is installed onto main board.
