3. DIMMs must be installed in pairs.
   The memory sockets are colored black or white to indicate which slots are paired by matching colors.
4. Each pair of DIMMs must be identical (same manufacturer, size and speed).
5. Populate the DIMMs in the slots farthest from the CPU first.
   The first pair to be populated should be D7/D6, then D5/D4, and so on.
