Memory Subsystem

The server boards supports up to four DIMM slots for a maximum memory capacity of 8 GB. The
DIMM organization is x72, which includes eight ECC check bits. The memory interface runs at
400MT/s. The memory controller supports memory scrubbing, single-bit error correction and
multiple-bit error detection and Intel x4 SDDC support with x4 DIMMs. Memory can be
implemented with either single-sided (one row) or double-sided (two row) DIMMs.
The figure below provides a block diagram of the memory sub-system implemented on the
board.
3.1.2.1 Memory DIMM Support
The board supports DDR2-400 compliant ECC DIMMS operating at 400MT/s. Only DIMMs
tested and qualified by Intel or a designated memory test vendor are supported on this board.
All DIMMs are supported by design, but only fully qualified DIMMs will be supported on the
board.
The minimum supported DIMM size is 256MB. Therefore, the minimum main memory
configuration is 1 x 256MB or 256MB. The largest size DIMM supported is a 2GB registered
DDR2-400 ECC DIMM based on 1Gb technology. Therefore, the maximum main memory
configuration is 4 x 2GB or 8GB.
Only registered DDR2-400 compliant, ECC, DDR2 memory DIMMs are supported
ECC single-bit errors (SBE) are corrected and multiple-bit error (MBE) are detected.
The server boards support Intel® x4 SDDC with x4 DIMMs.
The maximum memory capacity is 8GB
The minimum memory capacity is 256MB
