The DIMMs must be added in pairs within the same DIMM group, and each pair
used must have two identical DIMMs installed – that is, both DIMMs in each group
must be from the same manufacturer and must have the same capacity (for example,
two 512-Mbyte DIMMs or two 1-Gbyte DIMMs).
Note – Each CPU/memory module must be populated with a minimum of two
DIMMs, installed in either group 0 or group 1.
Caution – DIMMs are made of electronic components that are extremely sensitive
to static electricity. Static from your clothes or work environment can destroy the
modules. Do not remove a DIMM from its antistatic packaging until you are ready to
install it on the CPU/memory module. Handle the modules only by their edges. Do
