If
you
are
planning
to
install
or
remove
a
microprocessor,
memory
module,
PCI
adapter,
battery,
or
other
non-hot-swap
optional
device,
turn
off
the

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
installing
DIMMs:
v
The
server
supports
up
to
12
Fully
Buffered
DIMM
PC2-5300
512
MB,
1
GB,
2
GB,
and
4
GB
DIMMs,
for
a
maximum
of
48
GB
of
system
memory.
See
http://www.ibm.com/servers/eserver/serverproven/compat/us/
for
a
list
of
memory
modules
that
you
can
use
with
the
server.
Note:
Because
some
memory
is
reserved
for
system
operation,
the
actual
usable
memory
size
that
is
reported
by
the
operating
system
is
less
than
the
total
installed
size.
v
The
server
comes
with
a
minimum
of
two
512
MB
DIMMs,
installed
in
slots
1
and
4.
When
you
install
additional
DIMMs,
you
must
install
two
identical
DIMMS
at
a
time,
in
the
order
shown
in
the
following
table,
to
maintain
performance.
