Installing

 

a

 

memory

 

module

 

The

 

following

 

notes

 

describe

 

the

 

types

 

of

 

dual

 

inline

 

memory

 

modules

 

(DIMMs)

 

that

 

the

 

server

 

supports

 

and

 

other

 

information

 

that

 

you

 

must

 

consider

 

when

 

you

 

install

 

DIMMs:

 

v

   

The

 

server

 

supports

 

only

 

industry-standard,

 

1.8

 

V,

 

240-pin

 

double-data-rate

 

2

 

(DDR2),

 

800

 

MHz,

 

PC2-5300

 

or

 

PC2-6400,

 

unbuffered,

 

synchronous

 

dynamic

 

random-access

 

memory

 

(SDRAM)

 

dual

 

inline

 

memory

 

modules

 

(DIMMs)

 

with

 

error

 

correcting

 

code

 

(ECC).

 

These

 

DIMMs

 

must

 

be

 

compatible

 

with

 

the

 

latest

 

DDR2

 

or

 

800

 

MHz

 

SDRAM

 

unbuffered

 

DIMM

 

specification.

 

For

 

a

 

list

 

of

 

supported

 

optional

 

devices

 

for

 

the

 

server,

thinkserver.

 

v

   

The

 

optional

 

DIMMs

 

that

 

are

 

available

 

for

 

the

 

server

 

are

 

1

 

GB

 

and

 

2

 

GB.

 

The

 

server

 

supports

 

a

 

minimum

 

of

 

1

 

GB

 

and

 

a

 

maximum

 

of

 

8

 

GB

 

of

 

system

 

memory.

 

v

   

Some

 

servers

 

come

 

with

 

two

 

1-

 

GB

 

DIMMs

 

installed.

 

Depending

 

on

 

the

 

DIMM

 

sizes

 

that

 

are

 

installed

 

in

 

your

 

server,

 

the

 

server

 

can

 

support

 

two

 

or

 

four

 

DIMMs.

 

The

 

1-

 

GB

 

DIMM

 

and

 

2-GB

 

DIMM

 

option

 

kits

 

each

 

contain

 

two

 

DIMMs.

 

v

   

The

 

system

 

board

 

contains

 

four

 

DIMM

 

connectors

 

and

 

supports

 

two-way

 

memory

 

interleaving.

 

For

 

two-way

 

memory

 

interleaving,

 

DIMMs

 

must

 

be

 

installed

 

in

 

matched

 

pairs.

 

If

 

one

 

DIMM

 

is

 

installed

 

in

 

the

 

DIMM

 

1

 

connector,

 

when

 

you

 

install

 

an

 

additional

 

DIMM,

 

it

 

must

 

be

 

installed

 

in

 

the

 

DIMM

 

3

 

connector,

 

and

 

it

 

must

 

be

 

the

 

same

 

size,

 

speed,

 

type,

 

and

 

technology

 

as

 

the

 

DIMM

 

in

 

the

 

DIMM

 

1

 

connector.

 

You

 

can

 

use

 

compatible

 

DIMMs

 

from

 

various

 

manufacturers.

 

If

 

you

 

install

 

a

 

second

 

pair

 

of

 

DIMMs

 

in

 

the

 

DIMM

 

2

 

and

 

DIMM

 

4

 

connectors,

 

they

 

do

 

not

 

have

 

to

 

be

 

the

 

same

 

size,

 

speed,

 

type,

 

and

 

technology

 

as

 

the

 

DIMMs

 

in

 

the

 

DIMM

 

1

 

and

 

DIMM

 

3

 

connectors.

 

However,

 

the

 

size,

 

speed,

 

type,

 

and

 

technology

 

of

 

the

 

DIMMs

 

that

 

you

 

install

 

in

 

the

 

DIMM

 

2

 

and

 

DIMM

 

4

 

connectors

 

must

 

match

 

each

 

other.

 

v

   

The

 

maximum

 

operating

 

speed

 

of

 

the

 

server

 

is

 

determined

 

by

 

the

 

slowest

 

DIMM

 

in

 

the

 

server.

 

v

   

The

 

server

 

can

 

operate

 

in

 

single-channel

 

mode

 

or

 

dual-channel

 

mode.

 

v

   

DIMM

 

population

 

is

 

based

 

on

 

single-rank,

 

double-rank,

 

or

 

combined

 

single-rank

 

and

 

double-rank

 

DIMMs.

 

DIMMs

 

must

 

be

 

installed

 

in

 

order,

 

starting

 

with

 

the

 

DIMM

 

connector

 

that

 

is

 

farthest

 

from

 

the

 

memory

 

controller

 

hub.

 

Double-rank

 

DIMMs

 

must

 

be

 

installed

 

in

 

the

 

DIMM

 

connector

 

that

 

is

 

farthest

 

from

 

the

 

memory

 

controller

 

hub

 

when

 

you

 

install

 

a

 

combination

 

of

 

single-rank

 

and

 

double-rank

 

DIMMs.

 

The

 

following

 

tables

 

show

 

examples

 

of

 

populating

 

the

 

server

 

with

 

different

 

combinations
