7.2 DIMMs Supported

If DIMMs of different speeds are mixed, all channels operate at the fastest common frequency. UDIMMs are not supported. The first DIMM slot in each channel is color‐coded with white ejection tabs for ease of identification.

The M910’s DIMM sockets are placed 0.40‖ apart, center‐to‐center, to provide enough space for sufficient airflow to cool stacked DIMMs. DIMMs must be installed in each channel starting with the DIMM farthest from the processor (DIMM 1). Population order is identified by silkscreen and a label. The order is dependent on the memory configuration used. See Table 8 for DIMM naming and population ordering.

7.4 Intel 7500 Scalable Memory Buffer (SMB)

The Intel 7500 SMB supports one Intel Scalable Memory Interconnect (Intel SMI), 2 DDR3 channels, and 1 SMBus slave interface at 100KHz. It does not support the repeater functionality. Target package size is 19.5mm x 24.5mm with 0.8 mm pitch. Intel SMI supports link speeds of 4.8, 5.86, and

6.4GT/s with 11 Southbound lanes (9 data + 1 CRC + 1 spare) and 14 Northbound lanes (12 data + 1 CRC + 1 spare).

The DDR3 interface supports x4 and x8 single-rank, dual-rank, and quad-rank RDIMMs, and up to 2 RDIMMS per channel. Each DDR3 channel supports a maximum of 8 ranks. DDR3 speeds are 800, 978, and 1066 MHz. DRAM technology comes in 1 and 2Gb sizes. DIMM capacity is 1, 2, 4, 8, or 16GB (16GB with QR DIMMS only).

7.5 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 7.
