The Cache Memory
This system board is equipped (built-in) with
a 160-pin Dual Readout Socket for either a 256KB or a 512KB Pipeline Burst
Cache module for its Second Level Cache (L2). There is no jumper to be
set as the system board will automaticalley detect the cache module and
its size when installed.
Some Cache Memory
Considerations:
Pipeline
Burst Cache Module must conform to COAST standard version 3.0 or later,
and it must be Intel VX compatible.
Maximum
Second Level Cache can not exceed 512KB.

The Memory
This system board can support up to 128MB main
memory wtih 4 auto banking 72-pin SIMM slots for Fast Page Mode or EDO
DRAM, and 2 168-pin DIMM sockets for Fast Page Mode DRAM, EDO DRAM,
or SDRAM.
Some Memory Considerations:
If
Bank 0 of SIMM sockets is to be used, then DIMM 1 socket can NOT be used.
If
Bank 1 of SIMM sockets is to be used, then DIMM 2 socket can NOT be used.
If
DIMM 1 socket is to be used, then Bank 0 of SIMM sockets can NOT be used.
If
DIMM 2 socket is to be used, then Bank 1 of SIMM sockets can NOT be used.
All
SIMM sockets are compatible with Fast Page Mode and EDO DRAM SIMM modules.
All
DIMM sockets are compatible with Fast Page Mode, EDO DRAM modules, and
SDRAM module.
If
SDRAM module is installed on the DIMM sockets, jumper JP7 A & B must
be set to 3.3V.
Maximum
memory on-board can not exceed 128MB in any combination.
Voltage Requirements:
There are 2 categories of memory modules in regard
to their voltage requirement. The memory modules' voltage requirement must
be obtained from the manufacturer of the memory modules. However, the following
can serve as a general guideline.
SIMM
- Fast Page Mode & EDO DRAM, can be 3.3V or 5.0V.
DIMM
- Fast Page Mode & EDO DRAM, can be 3.3V or 5.0V.
DIMM
- SDRAM (Sync. DRAM), can be 3.3V only.
If
2 DIMM memory modules are installed, both of them must use the same voltage.
All
SIMM sockets are for 5.0V memory modules only.
All
DIMM sockets are compatible with 3.3V and 5.0V memory modules.
