IBM BladeCenter HX5 Product Guide

IBM BladeCenter HX5 16
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 BladeCenter HX5 and the MAX5 memory expansion blade support DDR3 memory. The server has 16
DIMM sockets and the MAX5 has 24 DIMM sockets. When only one processor is installed, only eight of
the 16 DIMM sockets in the server are active (all sockets in the MAX5 are active, however).
The following tables lists memory options available for the HX5 server and for the MAX5 memory
expansion unit. Memory must be installed in pairs of two identical DIMMs per processors installed.
Although the DIMM pairs installed can be of different sizes, the pairs must be of the same speed.
