IBM BladeCenter HS22V Product Manual page 8

Quad-core Intel Xeon 5500 series processors:

1333 MHz when one single-rank or dual-rank RDIMM per channel is installed

1066 MHz when two single-rank or dual-rank RDIMMs per channel are installed

800 MHz when three single-rank or dual-rank RDIMMs per channel are installed

Dual-core Intel Xeon 5500 series processors only support memory speed at 800 MHz.

The HS22V supports both 1.5 V and 1.35 V DIMMs. Intel Xeon 5600 series processor can run DIMMs at
either 1.35 V or 1.5 V depending on DIMM voltage and configuration, while Intel Xeon 5500 series
processors run DIMMs at 1.5 V in all cases. Mixing 1.5 V and 1.35 V DIMMs in the same server is
supported, in such a case all DIMMs operate at 1.5 V. With 1.35V DIMMs if there is a need to run two
DIMMs per channel at 1333 MHz then DIMMs will operate at 1.5 V.
The following memory protection technologies are supported:
ECC

ChipKill (for x4-based RDIMMs)

Memory Mirroring

Memory Sparing

If Memory Mirroring is used then DIMMs must be installed in pairs (minimum of one pair per each CPU),
and both DIMMs in a pair must be identical in type and size. If Memory Sparing is used then DIMMs must
be installed in sets of three, and all DIMMs in the same set must be identical in type and size. Memory
sparing is only supported for Intel Xeon 5600 series processor-based systems.
The following two tables list memory options available for HS22V server - one of 5500 series processors
and one for 5600 series processors. DIMMs can be installed one at a time, but for performance reasons,
install them in sets of three, one for each of the three memory channels.
