Introduction

The Intel

Xeon

processor 3400 series are the next generation of 64-bit, multi-core

processors built on 45-nanometer process technology. Based on the low-power/high-
performance Intel microarchitecture, the processor is designed for a two-chip platform,
instead of the traditional three-chip platforms (processor, (G)MCH, and ICH). The two-
chip platform consists of a processor and Platform Controller Hub (PCH) and enables
higher performance, easier validation, and improved x-y footprint. The Intel

3400

Series Chipset components for servers and workstations are the PCH. The Intel

Xeon

processor 3400 series is intended for UP server and workstation platforms.

This document provides DC electrical specifications, signal integrity, differential
signaling specifications, pinout and signal definitions, interface functional descriptions,
and additional feature information pertinent to the implementation and operation of the
processor on its respective platform.

Note:

Throughout this document, the Intel

Xeon

processor 3400 series may be referred to

as “processor”.

Note:

Throughout this document, the Intel

Xeon

processor 3400 series refers to the Intel

Xeon

X3480, X3470, X3460, X3450, X3440, X3430, and L3426 processors.

Note:

Througout this document, the Intel

3400 Series Chipset Platform Controller Hub may

be referred to as “PCH”.

Note:

Some processor features are not available on all platforms. Refer to the processor

specification update for details.

Included in this family of processors is an integrated memory controller (IMC) and
integrated I/O (IIO) (such as PCI Express* and DMI) on a single silicon die. This single
die solution is known as a monolithic processor. For specific features supported on
individual Intel Xeon processor 3400 series SKUs, refer to the Intel

Xeon

Processor

3400 Series Specification Update.
