Power Supply - Intel S5500BCR Service Manual

Mixing memory type, size, speed, and/or rank on this platform has not been validated and is not
supported
Mixing memory vendors is not supported on this platform by Intel
Non-ECC memory is not supported and has not been validated in a server environment
DDR3-800, DDR3-1066, or DDR3-1333
DIMM within a channel must be populated starting with the first slot (blue slot) of the channel: DIMM_A1,
DIMM_B1, DIMM_C1, DIMM_D1, DIMM_E1, or DIMM_F1.
When installing Quad-rank DIMM, you must populate Quad-rank DIMM starting with the first slot (blue
slot) of each channel.
For a complete list of supported memory DIMMs, see the links under
Channel Population Requirements for Memory RAS Modes
®
The Intel Server Board S5520HC /S5520HCT/S5500HCV support two memory RAS modes: Independent
Channel Mode, and Mirrored Channel Mode. The rules on channel population and channel matching vary by
the RAS mode used. Note that the support of RAS modes that require matching DIMM population between
channels (Mirroring) and require that ECC DIMMs must be populated.
Independent Channel Mode
You can populate channels in any order in Independent Channel Mode. You can populate all three channels in
any order and have no matching requirements. All channels must run at the same interface frequency, but
individual channels may run at different DIMM timings (RAS latency, CAS latency, and so on).
Mirrored Channel Mode
In Mirrored Channel Mode, the memory contents are mirrored between Channels A (D) and Channel B (E). As
a result of the mirroring, the total physical memory available to the system is half of what is populated. Mirrored
Channel Mode requires that Channel A (D) and Channel B (E) must be populated identically. DIMM slot
populations within a channel do not have to be identical but the same DIMM slot location across Channel A (D)
and Channel B (E) must be populated the same. Channel C (F) is unused in Mirrored Channel Mode.

NOTE
For help with memory population rules, refer to the Intel
Technical Product Specification.

Power Supply

A minimum of 550 W is recommended, or decide your system power supply capacity using the Intel
Budget Tool. Your supply must provide a minimum of 3 amps of 5-V standby current or the board will not boot.
