System memory Installation
The mainboard provides four 168-pin DIMM sites for memory expansion..
The DIMM socket supports 1Mx64(8MB), 2Mx64(16MB), 4Mx64(32MB),
8Mx64(64MB),and16Mx64(128MB)or double sided DIMM modules. Minimum
memory size is 8MB and maximum memory size is 512 MB SDRAM. There
are four Memory module sockets on the system board.(Total eight banks) In
order to create a memory array, certain rules must be followed. The following
set of rules allows for optimum configurations.
•
The memory array is 64 or 72 bits wide. (Without parity or with
parity)
•
Support single and double density DIMMs.
The following is the valid memory configuration:
Ba nk
Memory Module
Total Memory
Ba nk0
(DIMM1)
8MB,16MB, 32MB,64MB, 128MB
8MB~128MB
Ba nk1
(DIMM2)
8MB,16MB, 32MB,64MB, 128MB
8MB~128MB
Ba nk3
(DIMM3)
8MB,16MB, 32MB,64MB, 128MB
8MB~128MB
Ba nk4
(DIMM4)
8MB,16MB, 32MB,64MB, 128MB
8MB~128MB

* * * This table depicts the addressing requirements for each of the
row/column organizations for each row size. The SDRAM components
used for the options shown in the table are as follows:
Option
SDRAM Component Type
1 (8MB)
1M x 16
2 (16MB)
2Mx8 or 2Mx32
3 (32MB)
4Mx16 or 4Mx4 (Registered DIMM only)
4 (64MB)
8Mx8
5 (128MB)
16Mx4 (Registered DIMM only)
Note:
Both 4Mx4 and 16Mx4 SDRAM devices are supported in the form of
Registered DIMMs only. 2 Bank version of 2Mx32 is addressed like a
2Mx8 device, 12 row x 9 column.
