Memory Configuration
The mainboard supports two banks of
72-pin SIMM, EDO DRAM.
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.
Cache Configuration
The mainboard has a write-back caching scheme. You can order 256KB
or 512KB Level 2 Pipelined Burst cache onboard to improve the system
performance.
