This main board can be installed with 72 pin SIMM module DRAM, or 168 pins
DIMM module synchronous DRAM. The DRAM memory system on main board
can support BANK 0, BANK 1, BANK 2, for 72 pin SIMM socket was defined to be
BANK 0, or BANK2 and SDRAM1 & SDRAM2 to be BANK 0 & BANK 1.
Because of the 72-pins SIMM module is 32 bits width using 2 pcs which can
match a 64 bits pentium system.
Install DRAM on this main board please reference the table below.

2-7 Central Processing Unit (CPU)
The main board provides a 321-pins ZIF Socket 7. The CPU on mother board
must have a fan attached to prevent overheating.
WARNING: Without a fan, the CPU will be overheated and cause damage to both the
CPU and the motherboard.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the lever sideways away from the socket then
upwards to a 90-degree right angle. Insert the CPU with the white dot as your
