Installing
a
memory
module
The
following
notes
describe
the
type
of
dual
inline
memory
modules
(DIMMs)
that
your
server
supports
and
other
information
that
you
must
consider
when
installing
DIMMs:
v
Your
server
supports
256
MB,
512
MB,
and
1
GB
DIMMs,
for
a
maximum
of
4
GB
of
system
memory.
Go
to
the
ServerProven
®
list
at
http://www.ibm/com/pc/compat
for
a
list
of
memory
modules
you
can
use
with
your
server.
v
The
amount
of
usable
memory
will
be
reduced
depending
on
the
system
configuration.
A
certain
amount
of
memory
must
be
reserved
for
system
resources.
The
BIOS
will
display
the
total
amount
of
installed
memory
and
the
amount
of
configured
memory.
v
Your
server
comes
with
one
512
MB
DIMM
installed
in
DIMM
connector
1.
If
your
system
has
one
DIMM
installed,
when
you
install
an
additional
DIMM,
it
must
be
installed
in
DIMM
connector
3,
and
must
be
the
same
size,
speed,
type,
and
technology
as
the
DIMM
installed
in
DIMM
connector
1.
You
can
mix
compatible
DIMMs
from
various
manufacturers.
v
If
you
install
a
second
pair
of
DIMMs
in
DIMM
connectors
2
and
4,
they
do
not
have
to
be
the
same
size,
speed,
type,
and
technology
as
the
DIMMs
installed
in
DIMM
connectors
1
and
3.
However,
the
size,
speed,
type,
and
technology
of
the
DIMMs
you
install
in
DIMM
connectors
2
and
4
must
match
each
other.
v
Install
only
2.5
V,
184-pin,
double-data-rate
(DDR),
PC2700
or
PC3200,
unbuffered
synchronous
dynamic
random-access
memory
(SDRAM)
with
error
correcting
code
(ECC)
DIMMs.
These
DIMMs
must
be
compatible
with
the
latest
PC2700
and
PC3200
SDRAM
unbuffered
DIMM
specification.
v
When
you
restart
the
server,
the
system
displays
a
message
indicating
that
the
memory
configuration
has
changed.
DIMM 3
DIMM 4
Complete
the
following
steps
to
install
a
DIMM:
1.
Read
the
safety
information
beginning
on
page
v
and
“Installation
guidelines”
on
page
7.
2.
Turn
off
the
server
and
peripheral
devices,
and
disconnect
the
power
cord
and
all
external
cables.
Remove
the
cover
(see
“Removing
the
cover”
on
page
