• You can install a minimum of 2 and a maximum of 8 FBDIMMs on the node board.
• You must install FB-DIMMs in pairs (refer to
• Both FB-DIMMs within a pair must have the same capacity and speed.
• 800-MT/s FB-DIMMs require 1600-MT/s processors to run at full speed.
• To configure memory for maximum performance, balance the DIMM capacity
across both memory branches; for example, if you install 2GB of memory in
Branch 0, you must also configure 2GB of memory in Branch 1 (refer to
• Unbalanced branch configurations can reduce overall memory performance up to
40%.
