Specification Update for the
Intel®Desktop Board DH61WW
This document is an update to the specifications contained in the Intel®Desktop Board
DH61WW Technical Product Specification (Order Number: G23564). It is intended for
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 2nd Generation Intel®Core™ Processor Family Specification Update
(Order Number: 457991) for specification updates concerning the 2nd Generation
Intel®Core™ Processor Family that may apply to the desktop board DH61WW. 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®6 Series Chipset and Intel®C200 Series Chipset Specification
Update (Order Number: 440377) for specification updates concerning the Intel®H61
Express Chipset that may apply to the desktop board DH61WW. 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 DH61WW 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.

6 Intel Desktop Board DH61WW Specification Update
Summary of Changes
The following table indicates the Specification Changes, Errata, Specification
Clarifications, or Documentation Changes that apply to the Intel®Desktop Board
DH61WW. Intel intends to fix some of the errata in a future revision of the desktop
board, and to account for the other outstanding issues through documentation or
specification changes as noted.
The following notations are used in the table:
Doc: Document change or update that will be implemented.
Plan Fix: This erratum may be fixed in a future revision of the desktop board, driver, or BIOS.
Fixed: This erratum has been previously fixed.
No Fix: There are no plans to fix this erratum.
Shaded: This erratum is either new or modified from the previous version of the document.
No. Plans Specification Changes
1 Doc The Intel®H61 Express Chipset does not support RAID. References to RAID in the
Technical Product Specification will be deleted in the next revision of the manual.
2 Doc The maximum memory supported will be changed from 16 GB to 8 GB in all affected
sections of the Technical Product Specification in the next revision of the manual.
No. Plans Errata
1 Plan Fix PCI cards
Specification Changes
The Specification Changes listed in this section apply to the Intel®Desktop Board
DH61WW Technical Product Specification (Order Number G23564).
1. The Intel H61 Express Chipset does not support RAID. References to RAID in
Technical Product Specification will be deleted in the next revision of the manual.
The following sections of the manual are affected:
⎯Table 1 Feature Summary
⎯Section 1.9.1.1 Serial ATA RAID
⎯Section 1.9.1.2 Intel®Rapid Recover Technology
⎯The Caution in Section 3.1 Introduction

2. The maximum memory supported will be changed from 16 GB to 8 GB in the
following sections of the Technical Product Specification in the next revision of the
manual:
⎯Table 1 Feature Summary
⎯Section 1.6 System Memory
⎯Section 2.1.1 Addressable Memory
⎯Figure 8 Detailed System Memory Address Map
⎯Table 9 System Memory Map
Errata
1. PCI cards that utilize a PCI Express* to PCI bridge component may
not work with Intel®Desktop Boards based on the Intel®6 Series
Chipset.
Problem: Intel®Desktop Boards DP67DE, DP67BA, DZ68DB, DH67BL, DH67GD,
DH67CL, DH61SA, DH61CR, DH61BE, and DH61WW do not support PCI add
in cards that utilize a PCI Express to PCI bridge component. A resource
conflict between the affected board and the PCI Express to PCI bridge
component included in some PCI card designs (usually video cards, and
digital video capture cards) results in the PCI card not being recognized by
BIOS and not functioning.
Implication: PCI cards utilizing a PCI Express to PCI bridge chip will not be recognized or
function when plugged into any PCI slot on the affected Intel Desktop
boards.
PCI cards that do not include a PCI Express to PCI bridge chip will operate
normally.
Workaround: None.
Status: This problem may be fixed on future releases of these Intel Desktop Board
products.
