Functional Architecture
3.3.2
Memory DIMM Support
The board supports un-buffered (not registered) DDR2 667/800 ECC or non-ECC DIMMs
operating at 667/800 MT/s. Only DIMMs tested and qualified by Intel or a designated memory
test vendor are supported on this board. Note that all DIMMs are supported by design, but only
fully qualified DIMMs will be supported on the board.
The minimum supported DIMM size is 512 MB. Therefore, the minimum main memory
configuration is 1 x 512 MB or 512 MB. The largest size DIMM supported is 2 GB and as such,
the maximum main memory configuration is 8 GB implemented by 4 x 2 GB DIMMs.
•
Un-buffered DDR2 667/800 compliant, ECC x8 and Non-ECC x8 or x16 memory DIMMs
are supported.
•
ECC single-bit errors (SBE) can be detected and corrected. Multiple-bit errors (MBE)
can only be detected.
•
The maximum memory capacity is 8 GB via four 2 GB DIMM modules.
•
The minimum memory capacity is 512 MB via a single 512 MB DIMM module.

I/O Sub-System
3.4.1
PCI Subsystem
The primary I/O buses for the server board are five independent PCI bus segments providing
PCI, PCIe* and PCI-X* resources (LX board SKU only). The PCI buses comply with the PCI
Local Bus Specification, Rev 2.3.
PCI segments A, B, C, and D are directed through the Intel
independently configured to PXH-V that is through Intel
PCI Segment F is directed through the MCH by PCIe* x8 interface. The table below lists the
characteristics of the three PCI bus segments.

The Intel
ICH9R provides a Legacy 32-bit PCI sub-system and acts as the central resource on
this PCI interface. P32-A supports the following embedded devices and connectors:
