Memory options
IBM DDR3 memory is compatibility tested and tuned for optimal System x performance and throughput.
IBM memory specifications are integrated into the light path diagnostics for immediate system
performance feedback and optimum system uptime. From a service and support standpoint, IBM memory
automatically assumes the IBM system warranty, and IBM provides service and support worldwide.
The HS22 has six DIMM sockets per processor (12 DIMMs in total) and uses Double Data Rate-3
(DDR-3) very-low-profile (VLP) registered DIMMs. Servers with Intel Xeon 5600 series processors
support 16GB DIMMs meaning a total of up to 192 GB of RAM is supported. Servers with Intel Xeon 5500
series processors support 8GB DIMMs meaning a total of up to 96 GB of RAM is supported. The memory
DIMMs connects directly to one of the processors. With one processor installed, only six DIMMs can be
accessed. To access memory in the other six DIMM connectors, the second processor must be installed.
The following two tables list memory options available for HS22 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).
