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
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.

Performance Tuning Using BIOS
Setup
3.1 Hardware Considerations for Performance Tuning
3.1.1 System Cooling
Performance tuning may result in additional system heat generation. Increased
cooling capability may be required to allow performance tuning and operation of a
performance tuned system while maintaining stable operation . Considerations for
increasing cooling capability may include, but are not limited to, chassis type, selection
of air or liquid cooling, processor cooler design, memory module design, and overall
system airflow. Extreme performance tuning requires system designs with
increasingly sophisticated cooling capabilities. It is beyond the scope of this guide to
provide detailed recommendations for system cooling.
CAUTION
Cooling induced moisture condensation will result in risk for electrical shorting and subsequent
damage to the board and/or the system.
3.2 Accessing BIOS Setup
The BIOS setup screen can be accessed at system startup by pressing the F2 key at
the BIOS screen prompt. It is advisable to run the latest BIOS revision to ensure that
performance features are at the highest level of optimization. The latest version BIOS
can be obtained from http://downloadcenter.intel.com. Instructions for loading the
BIOS i
Before initiating performance tuning, ensure that the BIOS setup defaults have been
loaded by pressing F9 while in BIOS setup mode and then pressing F10 to save those
settings.
