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,
