When installing DIMMs, note the following:
• Different capacity DIMMs look alike. Make sure that you know the capacity of each
DIMM before you install it in a socket.
• Install only approved DIMMs available from your service representative.
• DIMMs must be installed in matched pairs. A matched pair is comprised of two alternate
sockets (see below). DIMMs within a pair must be identical (same capacity and same
number of chips on each side). For example, in a two-DIMM configuration, populate
DDRII 4 and DDRII 2 with DIMMs of identical capacity, with the same number of chips
on each side
