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
uses
interleaved
DIMMs,
which
you
must
add,
remove,
or
replace
in
pairs.
Both
DIMMs
in
a
pair
must
have
the
same
size,
type,
speed,
and
technology.
The
server
comes
with
one
pair
of
DIMMs
that
are
installed
in
DIMM
connectors
1
and
2
on
the
system
board.
v
You
can
increase
the
amount
of
memory
in
the
server
by
replacing
the
installed
DIMMs
with
higher-capacity
DIMMs
or
by
installing
additional
pairs
of
DIMMs.
v
To
optimize
system
performance
in
a
single-microprocessor
or
dual-microprocessor
configuration,
install
DIMMs
in
the
following
sequence.
Do
not
install
DIMMs
in
connectors
7
through
12
if
microprocessor
socket
2
(system-board
identifier
CPU2)
is
empty.
