6.4 Processor Configurations
The PowerEdge M910 is designed to support either a dual CPU configuration with FlexMem Bridge or a
4 CPU configuration. In either configuration, all IO and memory is available in the system. While not
formally supported, single CPU configurations with a processor installed in CPU1 will allow the
system to boot for diagnostic purposes.
The Intel Xeon processor 6500 series is for 2-socket configurations only and cannot be upgraded to a
4-socket configuration.
6.5 FlexMem Bridge
In a 4-CPU configuration, the PowerEdge M910 uses only one memory controller per CPU. This single
controller connects to two memory buffers via Intel SMI links. Each memory buffer in turn connects
to four DDR3 DIMMs. In a typical Intel Xeon processor 6500/7500 series configuration, only the
