Notes: 1. Place DIMMs in “X” location.
2. DIMM population must correspond to the above tables.
3. DIMM modules support 1 GB, 2 GB, 4 GB and 8 GB DIMMS.
4. The size of each DIMM must be the same across the configuration.
5. Do not mix UDIMMs with RDIMMs.
Memory identification
Generally, there are some memory information printed on the label of the DIMM module. Different vendors may
have different formats but the convention is usually like this:
Memory installation
WARNING: Memory of the identical size, speed, and organization must be installed in the same colored DIMM
slots.
Follow these steps:
