The Dual-Core Intel
®
Xeon
®
Processor 7000 Series may contain design defects or errors known as errata which may cause the product to deviate
from published specifications. Current characterized errata are available on request.
64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications
enabled for Inte
®
64 architecture. Processors will not operate (including 32-bit operation) without an Intel
®
64 architecture-enabled BIOS.
Performance will vary depending on your hardware and software configurations. Consult with your system vendor for more information.
Contact your local Intel sales office or your distributor to obtain the latest specifications and before placing your product order.
I

C is a two-wire communications bus/protocol developed by Philips. SMBus is a subset of the I
2
C bus/protocol and was developed by Intel.
Implementations of the I
2
C bus/protocol may require licenses from various entities, including Philips Electronics N.V. and North American Philips
Corporation.
