4.8GT/s, 5.86GT/s and 6.4GT/s with 11 southbound lanes (nine data, one CRC and one spare) and 14

Northbound lanes (12 data, one CRC and one spare).

The DDR3 interface supports x4 and x8 single-rank, dual-rank and quad-rank RDIMMs — up to two

RDIMMS per channel. Each DDR3 channel supports a maximum of eight ranks. DDR3 speeds are

800MT/s, 978MT/s, 1066MT/s and 1333MT/s. DRAM technology comes in 1Gb and 2Gb sizes. DIMM

capacity is 2GB, 4GB, 8GB, 16GB or 32GB (16GB with QR DIMMS only).

Memory RAS support

The Intel Xeon processor 6500 and 7500 series supports high-availability memory modes including

rank and DIMM sparing as well as memory mirroring. The M910 supports rank sparing only and

mirroring as shown in Table 10.

Mirroring

For mirroring, the M910 will support two-processor/four-processor configurations with 32 DIMMs

only. When mirroring is enabled, only half of the physical memory will be visible to the system

software. A full copy of the memory is maintained, and in the event of an uncorrectable error, the

system will switch over to the mirrored copy. In two-processor mode, the mirroring will be inter-

node with hemisphere mode enabled. In this case, the memory controller (MBox) of CPU1 is

mapped to the corresponding MBox of CPU2.

For four-processor configurations, the PowerEdge M910 also supports mirroring in the inter-socket

mode (intra-socket is not possible in four-processor configurations because each processor has

only one MBox connected to memory buffers). In this four-processor case, the memory on CPU1 is

mirrored with memory on CPU3, while memory on CPU2 is mirrored with memory on CPU4.
