If an FCC declaration of conformity marking is present on the board, the following statement applies:
FCC Declaration of Conformity
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device
may not cause harmful interference, and (2) this device must accept any interference received, including interference that
may cause undesired operation.
For questions related to the EMC performance of this product, contact:
Intel Corporation, 5200 N.E. Elam Young Parkway, Hillsboro, OR 97124
1-800-628-8686
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment to an outlet on a circuit other than the one to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Any changes or modifications to the equipment not expressly approved by Intel Corporation could void the user’s authority to
operate the equipment.
Tested to comply with FCC standards for home or office use.
Canadian Department of Communications Compliance Statement
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus set out in the
Radio Interference Regulations of the Canadian Department of Communications.
Le présent appareil numerique német pas de bruits radioélectriques dépassant les limites applicables aux appareils
numériques de la classe B prescrites dans le Réglement sur le broullage radioélectrique édicté par le ministére des
Communications du Canada.

Main Memory
NOTE
To be fully compliant with all applicable Intel
®
SDRAM memory specifications, the board should
be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your
memory modules do not support SPD, you will see a notification to this effect on the screen at
power up. The BIOS will attempt to configure the memory controller for normal operation.
The desktop board supports dual or single channel memory configurations defined in Table 6.
