Memory options

IBM DDR3 memory is compatibility tested and tuned for optimal IBM System x® performance and
throughput. IBM memory specifications are integrated into the light path diagnostics panel 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 x3250 M5 server has four DIMM slots, and only DDR3 ECC UDIMMs are supported. The processor
has two memory channels, and there are two DIMMs per channel.
The following rules apply when selecting the memory configuration:
If more than one DIMM is planned to be installed, DIMMs must be installed in a pair, and both DIMMs

in a pair must be identical in type and size.
Intel Xeon processor E3-1200 v3 product family supports up to 1600 MHz memory speeds for one

DIMM per channel and two DIMMs per channel configurations provided that the processors support
this memory speed.
The x3250 M5 server supports ECC memory protection.
The following table lists the memory options that are available for the x3250 M5 server.
