PowerEdge R910
The R910 utilizes DDR3 memory providing a high performance, high-speed memory interface capable of
low latency response and high throughput. The R910 supports RDIMMs only.
The R910 utilizes Intel Xeon 7500 series processors that have one memory controller hub and two
integrated memory controllers. Each of those memory controllers has two SMI channels that connect to
the Intel 7500 Scalable Memory Buffer.
The DDR3 memory interface consists of 16 Intel 7500 Scalable Memory Buffers, each of which has two
DDR3 memory channels. Each channel supports up to two RDIMMs (single/dual/quad-rank). By limiting
to two DIMMs per DDR channel, the system can support DIMMs running at 1066 MTs.
