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
industry-standard,
667
MHz,
unbuffered
PC2-5300,
double-data-rate
2
(DDR2)
dual
inline
memory
modules
(DIMMs)
error
correcting
code
(ECC)
memory.
v
The
system
board
contains
four
DIMM
connectors
and
supports
two-way
memory
interleaving.
v
The
DIMM
options
that
are
available
for
the
server
are
512
MB,
1
GB,
and
2
GB.
The
server
supports
a
minimum
of
512
MB
and
a
maximum
of
8
GB
of
system
memory.
v
The
server
comes
with
one
512
MB
DIMM
or
two
512
MB
DIMMs
installed.
Depending
on
the
DIMM
sizes
that
you
select,
the
server
also
supports
one,
two
or
four
DIMMs.
The
512
MB
DIMM
option
kit
contains
one
DIMM;
however,
the
1
GB
DIMM
and
2
GB
option
kits
each
contain
two
DIMMs.
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.
To
view
the
total
amount
of
installed
memory
and
the
amount
of
configured
memory,
run
the
Configuration/Setup
Utility
program
and
select
System
Summary
from
the
menu.
For
additional
information,
see
v
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
mix
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
Install
only
1.8
V,
184-pin,
double-data-rate
2
(DDR2),
667
MHz,
PC2-5300,
unbuffered
synchronous
dynamic
random-access
memory
(SDRAM)
with
error
correcting
code
(ECC)
DIMMs.
These
DIMMs
must
be
compatible
with
the
latest
DDR2
667
MHz
SDRAM
unbuffered
DIMM
specification.
For
a
list
of
supported
optional
devices
for
the
server,
see
http://www.ibm.com/servers/eserver/
v
When
you
restart
the
server
after
you
add
or
remove
a
DIMM,
the
server
displays
a
message
that
the
memory
configuration
has
changed.
