WARNING

Altering clock frequency and/or voltage may (i) reduce system stability and useful life of the system and processor; (ii) cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat or other damage; and (v) affect system data integrity. Intel has not tested and does not warranty the operation of the processor beyond its specifications.

WARNING

Altering PC memory frequency and/or voltage may (i) reduce system stability and useful life of the system, memory and processor; (ii) cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat or other damage; and (v) affect system data integrity. Intel assumes no responsibility that the memory included, if used with altered clock frequencies and/or voltages, will be fit for any particular purpose. Check with the memory manufacturer for warranty and additional details.

Intel Desktop Board DH67BL Performance Tuning Guide

1 Introduction

Performance tuning of Intel® Desktop Board DH67BL enables useful gains that can enhance overall system performance for gaming, video editing, computation, performance benchmarking, and other uses.

This guide focuses on using the BIOS for performance tuning of Intel Desktop Board DH67BL. The main performance tuning focus area is Intel® HD Graphics. The procedures and examples included in this guide are for reference only and may not work in all situations and system configurations.

Intel Desktop Board DH67BL is designed with a number of enhancements to support performance tuning while protecting the user from overheating or damaging board components.

These enhancements include:

•Fan speed control — the processor and system fan speeds automatically increase when elevated temperatures are sensed.

•Processor thermal protection — the current applied to the processor is automatically reduced when the thermal protection temperature set point is reached.

•Processor voltage regulation thermal protection — the voltage regulation system current is automatically reduced when the thermal protection temperature set point is reached.

2.1Architecture

Intel Desktop Board DH67BL is an Intel® H67 Express chipset-based desktop board in microATX form factor. It supports the 2nd generation Intel® Core™ i7 processors, Intel® Core™ i5 processors, and other Intel® processors in the LGA1155 package. The board features DVI-I and HDMI* connectors, and supports dual independent display for processors with Intel® HD Graphics. Powered by the 2nd generation Intel Core processors, Intel Desktop Board DH67BL delivers a superb visual performance for sharper images, richer color, and life-like audio and video.

Intel Desktop Board DH67BL also offers premium features, such as two SATA 6 Gb/s ports, two USB 3.0 ports with 5 Gb/s link speed, and Intel® Rapid Storage Technology (Intel® RST) for RAID 0, 1, 5, and 10, which provides new levels of protection, performance, and expandability.
