Replacing
memory
(all
machine
types)
The
computer
has
four
connectors
for
installing
dual
inline
memory
modules
(DIMMs)
that
provide
up
to
a
maximum
of
4.0
GB
of
system
memory.
When
installing
DIMMs,
the
following
rules
apply:
v
Fill
each
DIMM
connector
sequentially,
starting
at
DIMM
connector
1.
v
Use
2.5
V,
184-pin,
333
MHz
double
data
rate
synchronous
dynamic
random
access
memory
(DDR
SDRAM).
v
Use
128
MB,
256
MB,
512
MB
or
1.0
GB
DIMMs
in
any
combination.
v
DIMMs
are
38.1
mm
(1.5
inches)
in
height.
Note:
Only
DDR

DIMMs
can
be
used.
