  -Mfgr’s System P/N’s: 470065-183, 470065-200, 470065-253, 470065-261, 504055-031, 504055-051, 504055-421, 504055-xx1, 504056-031, 504056-041, 504056-421, 504056-xx1, 504271-B21, 517607-055, 517607-135, 517607-425, 600911-041, 600911-421, 601568-035, 601568-055, 601568-075
  -DDR3-1333 modules automatically clock down to 1066MHz and 800MHz depending on which Intel Xeon model and the number of modules installed.
  -Due to chipset limitations, DDR3 Quad Rank memory will operate at 1066MHz in the first Triple Channel bank. Adding Quad Rank modules in the second Triple Channel bank will operate at 800MHz. The third memory bank must be unpopulated.
  -Due to chipset limitations, Unbuffered ECC DIMMs are limited to TWO Triple Channel Banks per processor on Intel Xeon 55xx series systems.
  -This system supports either Registered ECC or Unbuffered ECC memory. Mixing Registered ECC and Unbuffered ECC modules is not supported within this system.
  -Low Voltage DIMMs can only be used with Intel Xeon 5600 series processors. Some systems support Low Voltage and standard voltage DIMMs but do not allow mixing DIMM voltage; all DIMMs must be the same voltage. Check system documentation for mixing DIMM voltage.
  -4GB DDR3-1333 Reg ECC modules come in two versions: using x4 and using x8 DRAM. The two parts may be installed in the same system but not within the same memory bank. Use like modules for dual and triple channel operation.
