Memory installation guidelines:
•Memory modules must be identical in size, speed, and technology.
•DIMMs installed in memory sockets with white release tabs must be identical and similar rule applies for sockets with black and green release tabs. This ensures that identical DIMMs are installed in matched pairs - for example, A1 with A2, A3 with A4, A5 with A6, and so on.
Sample memory configurations
The following tables show sample memory configurations that follow the appropriate memory guidelines stated in this section.
NOTE: 1R, 2R, and 4R in the following tables indicate
NOTE: When using an 104 mm wide heat sink for a single processor, the memory module sockets A6, A8, A10, and A12 are not available for population.
