Installing
 
memory
 
Your
 
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
   
System
 
memory
 
is
 
divided
 
into
 
two
 
channels
 
(channel
 
A
 
and
 
B).
 
DIMM
 
connectors
 
1
 
and
 
2
 
are
 
channel
 
A,
 
and
 
DIMM
 
connectors
 
3
 
and
 
4
 
are
 
channel
 
B.
 
v
   
If
 
DIMM
 
connectors
 
1
 
and
 
3
 
(or
 
2
 
and
 
4)
 
are
 
filled
 
with
 
the
 
same
 
technology
 
and
 
size
 
of
 
memory,
 
the
 
system
 
operates
 
in
 
dual
 
channel
 
mode.
 
v

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.

are
 
25.4

(1.0
 
inch)
 
in
 
height.
Note:
  
Only
 
DDR
 
SDRAM
 
DIMMs
 
can
 
be
 
used.
