systems, or tools. It will contain Specification Changes, Errata, Specification

Clarifications, and Documentation Changes.

For specification updates concerning the Intel processor that apply to this desktop

board, refer to the following:

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®945 Express Chipset Family Specification Update (Order Number

307503) for specification updates concerning the 82945GC GMCH Controller and that

may apply to the desktop board D945GCLF. Unless otherwise noted in this document,

it should be assumed that any MCH errata for a given stepping are applicable to the

Altered Assembly (AA) revision(s) associated with that stepping.

Number 307014) for specification updates concerning the 82801GB I/O Controller Hub

and that may apply to the desktop board D945GCLF. Unless otherwise noted in this

document, it should be assumed that any ICH7 errata for a given stepping are

applicable to the Altered Assembly (AA) revision(s) associated with that stepping.

Intel Desktop Board D945GCLF 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.

8 Intel Desktop Board D945GCLF Specification Update

Specification Changes

Changes to the feature description in the board technical product specification.

Typically the customer does not have to do anything to achieve proper device

functionality as a result of the change.

1. Correction of a Table reference number in Section 2.5.1 of the Technical

Specification.

2.5.1 Power Supply Considerations

CAUTION

The +5 V standby line from the power supply must be capable of providing adequate

+5 V standby current. Failure to do so can damage the power supply. The total

amount of standby current required depends on the wake devices supported and

manufacturing options.

Additional power required will depend on configurations chosen by the integrator.

The power supply must comply with the indicated parameters of the ATX form factor

specification.

•The potential relation between 3.3 VDC and +5 VDC power rails

•The current capability of the +5 VSB line

•All timing parameters

•All voltage tolerances

For example, for a system consisting of a D945GCLF board (with integrated Intel®

Atom processor at 4 W), 2 GB DDR2 RAM, one hard disk drive, one optical drive, and

all board peripherals enabled, the minimum recommended power supply is 75 W.

Table 21 lists the recommended power supply current values.

Table 21.Recommended Power Supply Current Values

Output Voltage 3.3 V 5 V 12 V1 12 V2 -12 V 5 VSB

Current 0.51 A 7.75 A 0.52 A 0.32 A 0.018 A 0.3 A
