IBM System x3250 M4 12Memory optionsIBM 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 systemperformance feedback and optimum system uptime. From a service and support standpoint, IBM memoryautomatically assumes the IBM system warranty, and IBM provides service and support worldwide.The server has four DIMM slots, and only DDR3 ECC UDIMMs are supported. The CPU has two memorychannels, and there are two DIMMs per channel.Configuration rules:If more than one DIMM is planned to be installed, then DIMMs must be installed in a pair, and bothDIMMs in a pair must be identical in type and size.Models with Intel Xeon E3-1200 v2 series processors support DIMMs operating at up to 1600 MHzprovided the processors support this memory speed and all DIMMs installed are rated at 1600 MHz.The following table lists the memory options supported by the server.Table 5.
