HP 8000 tower manual Intel Processor Support, Chipset Components and Functionality

System Overview

2.3.1 Intel Processor Support

The models covered in this guide are designed to support Intel Celeron single and dual core processors, Intel Pentium Dual-Core processors, Intel Core2 Duo processors, and Intel Core2 Quad processors. These processors are backward-compatible with software written for earlier x86 microprocessors and include streaming SIMD extensions (SSE, SSE2, and SSE3) for enhancing 3D graphics and speech processing performance. Intel processors with vPro Technology include hardware-based tools that allow corporate IT organizations to remotely manage and protect systems.

The system board includes a zero-insertion-force (ZIF) Socket-T designed for mounting an LGA775-type processor package.

ÄCAUTION: The USDT form factor can support a processor rated up to 65 watts. The SFF and CMT form factors can support a processor rated up to 95 watts. Exceeding these limits can result in system damage and loss of data.

✎The processor heatsink/fan assembly mounting differs between form factors. Always use the same assembly or one of the same type when replacing the processor. Refer to the applicable Service Reference Guide for detailed removal and replacement procedures of the heatsink/fan assembly and the processor.

2.3.2Chipset

The Intel Q45 Express chipset consists of a Graphics Memory Controller Hub (GMCH) and an enhanced I/O controller hub (ICH10-DO). Table 2-3 compares the functions provided by the chipsets.
