Hardware Installation

2.2 System Memory

The system board is equipped with four

168-pin DIMM (Dual In-line Memory

Module) sockets that support unbuffered

PC-133/PC-100 SDRAM DIMM for

133MHz/100MHz system memory bus.

PC SDRAM (Synchronous Dynamic

Random Access Memory) is a fast

memory interface technology that uses

the clock on the chip to synchronize with

the CPU clock so that the timing of the

memory chips and the timing of the

CPU are synchronized. This saves time

during transmission of data, subsequently increasing system

performance.

You can use single-sided or double-sided DIMMs. 16MB, 32MB,

64MB and 128MB are single-sided DIMMs. 32MB, 64MB, 128MB

and 256MB are double-sided DIMMs. The following rules must be

followed when installing DIMM modules.

Warning:

Electrostatic discharge (ESD) can damage your system board,

processor, disk drives, add-in boards, and other components. Perform

the upgrade instruction procedures described at an ESD workstation

only. If such a station is not available, you can provide some ESD

protection by wearing an antistatic wrist strap and attaching it to a

metal part of the system chassis. If a wrist strap is unavailable,

establish and maintain contact with the system chassis throughout

any procedures requiring ESD protection.

DIMM Socket

DIMM 1

DIMM 2

DIMM 3

DIMM 4

SDRAM DIMM

Supports single-sided or double-sided DIMM.

 If you use double-sided DIMM, leave DIMM 4 empty.

 If you use single-sided DIMM, only install single-sided DIMM in

DIMM 4.

Only supports single-sided DIMM and can be used only if DIMM 3

is installed with single-sided DIMM too.
