hardware system manufacturers and software developers of applications, operating
systems, or tools. It will contain Specification Changes, Errata, Specification
Clarifications, and Documentation Changes.
Refer to the Intel®Core™ i7-800 and Intel®Core™ i5-700 Desktop Processor Series
Specification Update (Order Number: 322166) as well as to the Intel®Core™ i5-600,
Intel®Core™ i3-500 Desktop Processor Series and Intel®Pentium®Processor G6950
Series Specification Update (Order Number: 322911) for specification updates
concerning supported processors that may apply to the desktop board DH55PJ. Unless
otherwise noted in this document, it should be assumed that any Processor errata for a
given stepping are applicable to the Altered Assembly (AA) revision(s) associated with
that stepping.
Refer to the Intel®5 Series Chipset and Intel®3400 Series Chipset Specification
Update (Order Number: 322170) for specification updates concerning the Intel®H55
Express Chipset that may apply to the desktop board DH55PJ. Unless otherwise noted
in this document, it should be assumed that any Platform Controller Hub errata for a
given stepping are applicable to the Altered Assembly (AA) revision(s) associated with
that stepping.

Intel Desktop Board DH55PJ Specification Update 5
Terminology
Specification Changes are modifications to the current published specifications.
These changes will be incorporated in the next release of the specifications.
Errata are design defects or errors. Characterized errata may cause the desktop
board behavior to deviate from published specifications. Hardware and software
designed to be used with any given Altered Assembly (AA) and BIOS revision level
must assume that all errata documented for that AA and BIOS revision level are
present on all desktop boards.
Specification Clarifications describe a specification in greater detail or further
highlight a specification’s impact to a complex design situation. These clarifications
will be incorporated in the next release of the specifications.
Documentation Changes include typos, errors, or omissions from the current
published specifications. These changes will be incorporated in the next release of the
specifications.

2.2.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
•One PCI Express 2.0 x16: this connector supports simultaneous transfer speeds of
up to 8 GB/s of peak bandwidth per direction.
•Two PCI Express 2.0 x1: each of these connectors support simultaneous transfer
speeds of up to 250 MB/s (2.5 GT/s) of peak bandwidth per direction.
•Three Conventional PCI (rev 2.3 compliant) connectors.
2.2.2.6 Front Panel USB Headers
Figure 12 is a connection diagram for the front panel USB headers.
NOTES
•The +5 V DC power on the USB headers is fused.
•Use only a front panel USB connector that conforms to the USB 2.0 specification for
high-speed USB devices.
•USB Header 2 (FP USB 2) has Pin 10 routed to the HDD LED to support specific
USB SSD devices. Connecting any device to this header, that has any connection to
