Note that although the maximum speed at which the memory channel runs on the HS22 is 1333 MHz, this
depends on a combination of three items:
Processor memory speed: The processor has a maximum memory speed of 1333, 1066, or 800
MHz depending on the processor model. Only the X (Advanced) range of Xeon 5500 and 5600 series
processors supports a maximum memory channel speed of 1333 MHz. See the processor options
(Table 5) for the maximum memory speed.
Memory DIMM: Most but not all DIMMs listed in the previous tables support running at 1333 MHz.
Some only run at 1066 MHz. This is noted in the description of the DIMM.
Number of DIMMs installed: The HS22 implements memory so that 2 DIMMs are on each of the
three memory channels of the processor. if only 1 DIMM is installed to each channel (that is, 3
DIMMs per processor) then the DIMMs can operate at the lower of the DIMM rated speed and
processor memory channel rated speed, up to 1333 MHz. However at 2 DIMMs per channel (6
DIMMs per processor), memory can only operate at 1333 MHz if Xeon 5600 X (Advanced) range of
processors (models X56nn) are installed. All other processors (all 5500, L56nn, and E56nn) cannot
drive the memory channel at 1333 MHz if there are 2 DIMMs per channel.
In summary, to ensure DIMMs operate at 1333 MHz, select a Xeon X56nn processor and use DIMMs that
are rated at 1333 MHz. All DIMMs in the proceeding table support running at 2 DIMMs per channel at 1333
MHz.
The following memory protection technologies are supported:
ECC
ChipKill
Memory Mirroring
Memory Sparing
