Online-spare
memory
disables
a
failed
pair
of
DIMMs
from
the
system
configuration
and
activates
an
online-spare
pair
of
DIMMs
to
replace
the
failed
pair
of
DIMMs.
For
an
online-spare
pair
of
DIMMs
to
be
activated,
you
must
have
installed
an
additional
pair
of
DIMMs
of
the
same
speed,
type,
size
(or
larger),
and
technology
as
the
failed
pair
of
DIMMs.
When
you
use
online-spare
memory,
consider
the
following
information:
-
You
cannot
enable
online-spare
memory
while
the
computer
is
operating
in
mirroring
mode.
-
The
minimum
memory
configuration
is
two
double-rank
DIMMs
installed
in
branch
0,
DIMM
connection
1
(in
channel
0)
and
DIMM
connection
3
(in
channel
1).
-
The
spare
pair
of
DIMMs
must
be
the
same
speed,
type,
size
(or
larger),
and
technology
as
the
failed
pair
of
DIMMs.
-
Branch
0
and
branch
1
operate
independently.
v
The
following
notes
apply
when
the
computer
operates
in
the
non-mirroring
mode
(normal
mode).
–
The
computer
comes
with
two
512
MB
DIMMs
installed
in
DIMM
connectors
1
and
3.
The
second
pair
of
DIMMs
must
be
installed
in
DIMM
connectors
5
and
7.
The
third
pair
of
DIMMs
must
be
installed
in
DIMM
connectors
2
and
4.
The
fourth
pair
of
DIMMs
must
be
installed
in
DIMM
connectors
6
and
8.
–
DIMMs
must
be
installed
in
matched
pairs.
For
example,
the
DIMMs
in
DIMM
connector
1
and
3
must
be
identical
to
each
other,
but
do
not
have
to
be
identical
to
the
DIMMs
in
DIMM
connector
5
and
7.
But
the
DIMMs
in
DIMM
connector
5
and
7
must
be
identical
to
each
other.
The
DIMMs
in
each
pair
must
be
the
same
size,
speed,
type,
and
technology
as
each
other
but
do
not
have
to
match
the
other
pairs.
You
can
mix
compatible
DIMMs
from
various
manufacturers.
