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.
