Retainer bracket Heat sink release lever Microprocessor d. Slide the rear flange of the heat sink into the opening in the retainer bracket. e. Press down firmly on the front of the heat sink until it is seated securely. f. Rotate the heat-sink release lever to the closed position and hook it underneath the lock tab. 11. Install the microprocessor air baffle (see "Installing the microprocessor air baffle" on page 35). If you have other optional devices to install or remove, do so now. Otherwise, go to "Completing the installation" on page 81. 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. Table 3.

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
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.
