3.1.4 System Cooling
Performance tuning results 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 from refrigerant systems, dry ice, liquid nitrogen or other
uncommon cooling methods will result in risk for electrical shorting and subsequent damage to the
board and/or the system.
3.2 Suggestions for Effective Tuning
Optimal results will occur if tuning efforts are directed appropriately. For example, if
performance improvements with a certain gaming application are desired, then tuning
efforts should be directed at the system resources used by the game. If the game
software has intensive processor computational work, but relatively light demands on
system memory, then focusing performance tuning efforts on memory will not yield
significant improvements.
System resource (processor, memory, etc.) utilization can be determined by running
your software application while monitoring resource usage. Resource usage can be
monitored with the Intel®Extreme Tuning Utility. Also, your software supplier should
be able to provide information about system resource utilization with their application.
Video graphics performance increases may be needed to improve the overall
performance of gaming software. The supplier of the graphics card should be
contacted for information about performance tuning their hardware. External graphics
tuning is specific to the graphics card manufacturer and cannot be done using either
the Intel Desktop Board DP67BG BIOS or the Intel Extreme Tuning Utility.
Earlier performance tuning methods where the frequency of the system clock was
increased are now not the most effective means of boosting performance with the
processors in the 2nd generation Intel Core processor family that support turbo mode.
Turbo mode provides “on demand” performance when needed while allowing the
processor to run at a lower frequency with reduced heat generation and improved
efficiency when demand is low. With Intel Desktop Board DP67BG, Intel suggests
beginning tuning efforts by optimizing turbo mode performance and then utilizing the
system clock for secondary adjustments.
Keeping a written log of performance tuning settings and the results will be extremely
helpful. Your tuning efforts will be much more efficient if you can refer to the log for
settings that you have already tried. If you need to restore BIOS parameters to
something that worked previously, then information recorded in the log will be helpful.
