3. Change to Thermal Considerations, Section 2.12
Section 2.12, Thermal Considerations will change in its entirety as follows:
2.12 Thermal Considerations
CAUTION
The use of an Intel®Pentium®4 processor operating above 2.80 GHz with this
Intel®desktop board requires the following:
• A chassis with appropriate airflow to ensure proper cooling of the
components on the board
• A processor fan heatsink that meets the thermal performance targets for
Pentium 4 processors operating above 2.80 GHz
The use of an Intel Pentium 4 processor with 1 MB of L2 cache on this Intel
desktop board requires the following:
• A chassis with a maximum internal ambient temperature of 38 Degrees
Celsius
• A processor heatsink that provides omnidirectional airflow so that air is
drawn across the processor voltage regulator area (item A in Figure 26).
Figure 25a illustrates an omnidirectional airflow heatsink.

Failure to ensure appropriate airflow may result in reduced performance of both
the processor and/or voltage regulator or, in some instances, damage to the
desktop board. For a list of chassis that have been tested with Intel®desktop
boards please refer to the following website:
http://developer.intel.com/design/motherbd/cooling.htm
All responsibility for determining the adequacy of any thermal or system design
remains solely with the reader. Intel makes no warranties or representations that
merely following the instructions presented in this document will result in a
system with adequate thermal performance.
CAUTION
Ensure that the ambient temperature does not exceed the Desktop Board’s
maximum operating temperature. Failure to do so could cause components to
exceed their maximum case temperature and malfunction. For information about
the maximum operating temperature, see the environmental specifications in
Section 2.14.
CAUTION
Ensure that proper airflow is maintained in the processor voltage regulator
circuit. Failure to do so may result in damage to the voltage regulator circuit.
The processor voltage regulator area (item A in Figure 26) can reach a
temperature of up to 85 oC in an open chassis.

ERRATA
1. PCI Slot 1 Cannot be Used With Long PCI Add-in Cards
PROBLEM:A tall capacitor is located 3 ¼ inches behind PCI slot 1.
IMPLICATION:PCI cards conforming to the PCI specification but exceed 8 inches in length, may not be
useable in PCI slot 1.
WORKAROUND:None.
STATUS:This erratum may be fixed in a future hardware revision.
2. Advance Jack Sense May Not Recognize Devices Connected to a
Front Panel Audio Port
PROBLEM:The advanced jack sense with Auto Topology Switching, that is used by the audio codec to
recognize what device is connected to an audio port, may fail to report devices connected to a front-panel
port.
IMPLICATION:Devices connected through a front panel audio port will be detected and function correctly, but
the advance jack sense wizard will only report the device at start up.
WORKAROUND:None.
STATUS:This erratum will not be fixed.
3. Advance Jack Sense on Boards with 6-Channel Audio Will Report
“Microphone” for Any Device Connected to the Back Panel
Microphone Port (Pink)
PROBLEM:For boards with 6-channel audio, the advanced jack sense with Auto Topology Switching, that is
used by the audio codec to recognize what device is connected to an audio port, will report “Microphone” for
any device connected to the back panel pink microphone port.
IMPLICATION:The advanced jack sense wizard will report any device connected through the back panel
microphone port to be a “Microphone” and the wizard will prompt the user to verify this detection assumption.
WORKAROUND:None.
STATUS:This erratum will not be fixed.
4. Advance Jack Sense Will Not Detect Devices Connected to the
Center/LFE and Surround Ports
PROBLEM: Polling devices connected to the Center/LFE and Surround port would cause popping noise once
speakers are connected. Due to this anomaly, the advance jack sense wizard will not poll and report devices
connected to the Center/LFE and Surround ports although these devices will work correctly.

Intel®Desktop Board D865GRH Specification Update
11
IMPLICATION:Devices connected to the Center/LFE or Surround port will be detected and function correctly,
but the advance jack sense wizard will not poll and report the device.
WORKAROUND:None.
STATUS:This erratum will not be fixed.
5. Advance Jack Sense May Report Amplified Speakers as an Array
Microphone When Connected to The Microphone Port (Pink)
PROBLEM:The presence of voltage bias on the microphone jack during the detection phase is required for
accurate detection, but amplified speakers and array microphones have very similar impedance values.
IMPLICATION:Amplified speakers will be detected and function correctly, but the advance jack sense
wizard may report the device as an array microphone.
WORKAROUND:None.
STATUS:This erratum will not be fixed.
6. An Additional Reboot May Be Required After Installing Audio
Drivers for Microsoft Windows
* 98SE or Windows ME
PROBLEM: An application post-installer completes the driver installation and requires an additional reboot to
get full functionality in Windows 98SE or Windows ME.
IMPLICATION:An additional reboot is required after installing audio drivers for Windows 98SE or
Windows ME.
WORKAROUND:None.
STATUS:This erratum will not be fixed.
7. Private Information Manager (PIM) May Return an Error Message
When Used with Non-English Operating Systems
PROBLEM:When using a non-English operating system, typing characters that are not in the normal ASCII
character-set will cause an error message the next time PIM is started. A PIM update is required.
IMPLICATION:Using a non-English operating system and typing characters not in the normal ASCII
character-set will cause an error message the next time PIM is started.
WORKAROUND:A PIM update is available from http://www.wave.com/support/downloads_PIM.html.
STATUS:This erratum may be fixed in a future product release.

Intel®Desktop Board D865GRH Specification Update
12
8. System Memory May Be Reduced in Excess of the Amount of AGP
Aperture Size When 4GB of System Memory are Used
PROBLEM:The AGP aperture size setting in the system BIOS will consume, from available system memory,
2 times the amount applied in the AGP aperture setting when the maximum of 4 GB of system memory is
installed.
IMPLICATION:When 4GB of system memory are used, and system memory is allocated to AGP aperture
size in BIOS Setup, available system memory may be reduced by twice the amount allocated. A similar
impact to available system memory may occur from any allocation of system memory when 4 GB of system
memory is used. For example, increasing the video frame buffer in BIOS may also reduce available memory
in excess of the amount requested.
WORKAROUND:None.
STATUS:This erratum may be fixed in a future BIOS revision.
9. System May Intermittently Hang at POST Code 75 with SATA Hard
Disk Drives Attached
PROBLEM:An intermittent hang at POST code 75 may be observed when SATA Hard Disk Drives are used.
This intermittent hang is due to an erroneous circuit race condition in the system clock when spread spectrum
is enabled by BIOS.
IMPLICATION:The system hang is exhibited when the system clock’s internal circuitry is erroneously enabled
when spread spectrum is enabled on PLL1.
By setting the SMBUS register byte 0, bit 7, to 1 before spread spectrum is enabled and also enabling spread
spectrum earlier in the boot process (prior to enabling the SATA ports), this hang condition is avoided.
WORKAROUND:The user will need to reset the system.
STATUS:This issue may be fixed in a future BIOS revision, which allows the SATA Hard Disk Drives to be
reinitialized..

SPECIFICATION CLARIFICATIONS
The Specification Clarifications listed in this section apply to the Intel
®
Desktop Board D865GBF/D865GLC
Technical Product Specification
(Order Number C53954). All Specification Clarifications will be incorporated
into a future version of that specification.
1. Clarification of DDR Voltage
Section 1.6, System Memory, will change as follows:
1.6 System Memory
The Desktop Board D865GRH has four DIMM sockets and supports the
following memory features:
• 2.6 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts
• Unbuffered, single-sided or double-sided DIMMs with the following
restriction:
Double-sided DIMMS with x16 organization are not supported.
• 4 GB maximum total system memory. Refer to Section 2.2.1 on page 63 for
information on the total amount of addressable memory.
• Minimum total system memory: 64 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR400, DDR333, and DDR266 SDRAM DIMMs
2. Clarification of Section 2.11.1, DC Loading
Clarification to Section 2.11.1, DC Loading, will be added as follows:
2.11.1 DC LOADING
Table 41 lists the DC loading characteristics of the board. This data is based on a DC
analysis of all active components within the board that impact its power delivery
subsystems. The analysis does not include PCI add-in cards. Minimum values assume
a light load placed on the board that is similar to an environment with no applications
running and no USB current draw. Maximum values assume a load placed on the board
that is similar to a heavy gaming environment with a 500 mA current draw per USB
port. These calculations are not based on specific processor values or memory
configurations but are based on the minimum and maximum current draw possible from
the board’s power delivery subsystems to the processor, memory, and USB ports.

Intel®Desktop Board D865GRH Specification Update
14
Use the datasheets for add-in cards, such as PCI and AGP, to determine the overall
system power requirements. The selection of a power supply at the system level is
dependent on the system’s usage model and not necessarily tied to a particular
processor speed.
3. Change to Description of Section 2.11.3, Fan Connector Current
Supply, Correction of Processor and Voltage Regulator Fan
Current
Section 2.11.3, Fan Connector Current Supply will change in its entirety as follows:

may result in onboard component damage that will halt fan operation.
Table 42 lists the current capability of the fan connectors.
Table 42. Fan Connector Current Capability
Fan Connector Maximum Available Current
Processor fan 1600 mA
Front chassis fan 600 mA
Rear chassis fan 600 mA
4. Change to Description of Section 2.9.1, Front Panel Audio
Connector/Jumper Block
Section 2.9.1, Front Panel Audio Connector/Jumper Block will change in its entirety as follows:
2.9.1 FRONT PANEL AUDIO CONNECTOR/JUMPER BLOCK
This connector has two functions:
• With jumpers installed, the audio line out signals are routed to the back panel
audio line out connector.
• With jumpers removed, the connector provides audio line out and mic in
signals for front panel audio connectors.
Table 39 describes the two configurations of this connector/jumper block.
