You
can
increase
the
amount
of
memory
in
the
server
by
replacing
them
with
higher-capacity
DIMMs
or
installing
an
additional
pair
of
DIMMs
into
the
remaining
slots.
Figure
25
shows
the
memory
slots
on
the
system
board.
Note:
When
installing
additional
DIMMs,
always
install
in
pairs
starting
with
slots
1
and
2.

The
server
supports
Chipkill
™
memory
technology,
which
enables
the
server
to
function
with
one
bad
chip
on
a
DIMM.
The
bad
memory
module
must
be
on
an
x4
DIMM.
The
256
MB
and
512
MB
DIMMs
that
are
x8
DIMMs
do
not
support
Chipkill
memory
(see
Table

You
can
configure
the
server
to
use
memory
mirroring.
Memory
mirroring
stores
data
in
two
pairs
of
DIMMs
simultaneously.
When
using
memory
mirroring,
you
must
install
two
pairs
of
DIMMs
at
a
time.
All
the
DIMMs
you
use
in
memory
mirroring
must
be
identical.
See
Table
2
for
the
DIMM
pairs
that
are
in
each
pair.
Note:
The
use
of
memory
mirroring
decreases
the
amount
of
available
memory
by
half.
