When installing DIMMs, the following rules apply: v Fill each system memory connector sequentially, starting at DIMM connector 1. v Use 2.5 V, 184-pin, 266 MHz double data rate synchronous dynamic random access memory (DDR SDRAM). v Use 128 MB, 256 MB, 512 MB or 1.0 GB (when available) DIMMs in any combination. v DIMMs are 38.1 mm (1.5 inches) in height. Note: Only DDR SDRAM DIMMs can be used. To install a DIMM: 1. Remove the cover. See "Removing the cover" on page 40. 2. To locate the DIMM connectors. See "Identifying parts on the system board" on page 44. Chapter 5. Installing Options 47

Installing
memory
Your
computer
has
two
connectors
for
installing
dual
inline
memory
modules
(DIMMs)
that
provide
up
to
a
maximum
of
2.0
GB
of
system
memory.
When
installing
DIMMs,
the
following
rules
apply:
v
Fill
each
system
memory
connector
sequentially,
starting
at
DIMM
connector
1.
v
Use
2.5
V,
184-pin,

memory
(DDR
SDRAM).
v
Use
128
MB,
256
MB,
512
MB
or
1.0
GB
(when
available)
DIMMs
in
any
combination.
v
DIMMs
are
38.1
mm
(1.5
inches)
in
height.
Note:
Only
DDR
SDRAM
DIMMs
can
be
used.
To
install
a
DIMM:
1.
Remove
the
cover.
