55 • 16GB DIMM is only supported for Intel Xeon 5600 series processor. • Please refer to the User Guide for complete population for both single and dual processor configurations. Sparing mode: • In this mode, if system detects degrading memory and system still not crash, the data in failed channel will be copied to spare channel. Failed channel is then isolated and spare channel becomes active. But if any uncorrectable error happens before the isolation, it will still cause the system stop normal operation. • Channel 3 is the spare channel. Therefore, the effective size will be reduced by one-third. • Follow the population rules described in independent mode. • Sparing mode need all three channels with identical DIMMs. 1A, 2A and 3A should be the same type, size and manufacturer. 1B, 2B and 3B memory should be the same type, size and manufacturer. 1C, 2C and 3C memory should be the same type, size and manufacturer. Same rule is applied to CPU2. • Memory sparing mode is only supported by Intel Xeon 5600 series processor. Intel Xeon 5500 series processor does NOT support the memory sparing mode. • 3 DIMM per channel configuration is only available for single/dual rank RDIMM. • 16GB DIMM is only supported for Intel Xeon 5600 series processor. • Please refer to the User Guide for complete population for both single and dual processor configurations.
