The system board provides three 168-pin, gold plated, 3.3 V (5 V tolerance) DIMM sockets. The three (3) DIMM
sockets are arranged in one bank per one socket. The sockets are designated from Bank 0 to Bank 2. Each
bank provides a 64/72-bit wide data path. There are no jumper settings required for the memory size or type,
which is automatically detected by the system BIOS.

The sockets support 2M x 64 (16 MB), 4M x 64 (32 MB), 8M x 64 (64 MB) and 16M x 64 (128 MB) single- or
double-sided modules. Minimum supported memory size is 16 MB and maximum memory size is 384 MB,
using three 128 16M x 64 DIMM modules. DIMMs must be gold plated, 4-clock, 100 MHz of faster, unbuffered,
SDRAM modules. Each DIMM module must have an nvram, The contents of the nvram is programmed
according to Intel’s specification “4-CLOCK, 66 MHz, 64-Bit UNBUFFERED SDRAM DIMM, REVISION 1.0

”.

In addition to memory combinations mentioned in the table above, all memory combinations of mixing 16 MB,
32, MB, 64 MB and 128 MB DIMMs randomly in three sockets are allowed.

Example: 128 MB in socket 0, 32 MB in socket 1 and 64 MB in socket 2

Note:

All configurations use non-parity SDRAM DIMMs (i.e. ECC is not supported).
