    Figure 3.1 will be displayed. In addition, on Intel Desktop Board DP67BG at the top of the diagnostic LED bank, a red LED will illuminate when the watchdog timer is activated. The user can then go into the BIOS screen and manually reset performance parameters or use the F9 key to reset all BIOS defaults to restore system stability.

    Leave Enhanced Intel SpeedStep Technology and CPU C States enabled in the BIOS as shown in Figure 3.4. Turbo ratios require Enhanced Intel SpeedStep Technology enabled in order to function. Disabling C states prevents the processor from entering 1, 2, or 3 core ratios. Only the 4 core ratio will have an effect when C states are...

This setting prevents dynamic adjustments that could confuse tuning efforts. Later in the tuning procedure, the dynamic setting can be restored if it does not result in thermal throttling of the processor.

  • Page 19: Intel ® Turbo Boost Technology

    Inadequate cooling may cause the processor to throttle. You can use the Intel Extreme Tuning Utility monitoring features to track processor temperature. If the processor temperature increases steadily while running under load, the processor cooler capability to dissipate heat is being exceeded and you will need to reduce the TDP power limit to prevent throttling.

  • Page 20: Check Stability

    When the system can successfully boot into the operating system, various software applications can be used to stress the processor, memory, and other subsystems. When processor cores are idle, the Intel Core processors will operate at a reduced multiplier value. While running in the operating system, the application of a heavy load will bring all processor cores out of the idle and run them at the multiplier values selected in the BIOS setup.

  • Page 21: Increase System Clock Frequency

    With the 2 generation Intel Core processor family, the system clock frequency is limited to modest increases compared to earlier Intel processors. Limited processor frequency increases can be done by raising the system clock speed and leaving the turbo ratio multipliers unchanged. Performance tuning using the system clock should be done to augment processor performance improvements already obtained using turbo ratios.

  • Page 22: Tune Memory

    In addition, DIMM socket population will also affect system performance. Intel Desktop Board DP67BG has two independent memory channels which are indicated by blue or black memory DIMM sockets. For best performance, all sockets should be populated with memory matched by manufacturer, size, speed, and type.

    Note that the memory is not run directly from the host clock. The memory clock frequency is generated by the processor using input from the host clock signal received from the Intel P67 PCH. The default memory clock frequency runs at 133.3 MHz. Increasing the system clock frequency affects the memory...

    Intel DP67BG Desktop Board Performance Tuning Guide Example: If the host clock frequency was increased by 1% and a multiplier of 8 was being used then the new memory frequency would be (8) * (1.01) * (133.3 MHz) = 1077 MHz For the default 133.3 MHz memory clock, the resulting memory frequency with various...

    3.5.9 Archive Performance Settings The Intel Desktop Board DP67BG BIOS allows storing one set of parameter settings (profile) at any given time. If several groups of performance settings are needed by the user, the Intel Extreme Tuning Utility allows storing multiple profiles as shown in Figure 3.11.
