Note:
Due to various design, please ask your CPU dealer for the exact
VIO and VCORE voltage before you install it.
Memory Configuration
The mainboard supports two banks of
72-pin FPM/EDO/Burst EDO
DRAM (SIMM), and one strip of 3.3V 168-pin Unbuffered DIMM.
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 can install SIMM in any combination
without having to rely on a memory configuration table. Memory
configuration is thus Ò
Table-Free
Ó in any SIMM bank. You must install
two strips of SIMM modules to complete a bank.
