Installing
memory
modules
You
can
increase
the
amount
of
memory
in
the
blade
server
by
installing
additional
memory-module
options.
The
following
items
describe
the
types
of
dual
inline
memory
modules
(DIMMs)
that
the
blade
server
supports
and
other
information
that
you
must
consider
when
installing
DIMMs:
v
The
system
board
contains
four
DIMM
connectors
and
supports
two-way
memory
interleaving.
v
As
of
the
date
of
this
publication,
the
blade
server
supports
a
minimum
of
512
MB
and
a
maximum
of
8
GB
of
system
memory
(depending
on
the
blade
server
model).
The
DIMM
options
available
are
256
MB,
512
MB,
1
GB,
and
2
GB,
with
the
following
exceptions:
–
256
MB
DIMMs
are
not
supported
by
the
8842-4Tx
model.
–
2
GB
DIMMs
are
not
supported
by
the
8842-21x,
8842-E1x,
8842-E2x,
8842-41x,
and
8842-4Ax
models.
v
Install
only
2.5
V,
184-pin,
double-data-rate
(DDR),
PC2700,
registered
synchronous
dynamic
random-access
memory
(SDRAM)
with
error
correcting
code
(ECC)
DIMMs.
For
a
current
list
of
supported
DIMMs
for
the
blade
server,
go
to
http://www.ibm.com/pc/us/compat/.
v
Install
DIMMs
in
a
matched
pair.
Each
pair
must
be
the
same
size,
speed,
type,
and
technology.
You
can
mix
compatible
DIMMs
from
various
manufacturers.
The
second
pair
of
DIMMs
does
not
have
to
be
the
same
size
as
the
first
pair.
v
After
you
install
or
remove
a
DIMM,
the
new
configuration
information
is
automatically
saved
in
the
blade
server
firmware
code.
The
following
illustration
shows
how
to
install
DIMMs
on
the
system
board.
DIMM socket 1 (J25)
DIMM socket 2 (J28)
DIMM socket 3 (J32)
DIMM socket 4 (J40)
