Memory Configuration
The mainboard supports two banks of 72-pin SIMM modules and three
strips of 168-pin/3.3V Unbuffered DIMM modules. The mainboard
requires SIMM of at least 70ns access time.
The mainboard supports from 4 to 256 Mbytes with no other restrictions
on memory configurations. You must install two strips of SIMM
modules to complete a bank.
