Hardware Requirements
To avoid integration difficulties and possible board damage, your system must meet the
requirements outlined below. For a list of qualified components, see the links under
“Server System References”.
Processor
The Intel
®
Server System SR1690WB supports one or two Intel
®
Xeon
®
Processor 5500
series and Intel
®
Xeon
®
Processor 5600 series with 95W Thermal Design Power (TDP) or
less and with a max data transfer rate of 6.4 GT/s. For a complete list of supported
processors, see the links under “Server System References”.
Memory
The Intel
®
Server System SR1690WB supports a DDR3-based memory subsystem. The
Intel
®
Server System SR1690WB supports two DIMMs per channel. The silkscreen on
the board for the DIMMs displays DIMM_A1, DIMM_A2, DIMM_B1, DIMM_B2,
DIMM_D1, DIMM_D2, DIMM_E1, DIMM_E2. See Figure 11. The minimal memory
population possible is DIMM_A1.
Figure 11. DIMM Configuration Diagram
For two slots per channel configurations, the server board requires DDR3 DIMMs within
a channel to be populated starting with the DIMM farthest from the processor. See the
following figure (Figure 12).
For a complete list of supported memory DIMMs, see the links under “Server System
References”.
