DDR3 DIMMs must meet the following requirements:
Use only 240-pin DDR3 DIMMs.

A minimum of one 1 GB DDR3 DIMM is required in DIMM socket DIMM_A1.

Either registered DDR3 DIMMs (RDIMMs) or unbuffered ECC/non-ECC DDR3 DIMMs (UDIMMs). No mixing of

RDIMMs and UDIMMs.
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 / 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 Mode is the only mode that supports non-ECC DIMMs in addition to
ECC DIMMs.
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
Specification.
