- 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).
-
- Some Cache Memory
Considerations:
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
1 168-pin DIMM socket for Fast Page
Mode DRAM, EDO DRAM, or SDRAM.
- Some Memory
Considerations:
If
Bank 0 of SIMM sockets is to be used,
then the DIMM socket CANNOT be used.
If
the DIMM socket is to be used, then Bank
0 of SIMM sockets CANNOT be used.
All
SIMM sockets are compatible with Fast
Page Mode and EDO DRAM SIMM modules.
The
DIMM socket is compatible with Fast Page
Mode, EDO DRAM and SDRAM modules.
If
a SDRAM module is installed in the DIMM
socket, jumper JP7 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.
All
SIMM sockets are for 5.0V memory modules
only.
The DIMM socket is
compatible with 3.3V and 5.0V memory
modules.
