About
What is Intel® Turbo Boost Max Technology 3.0 and how does it work?

Intel® Turbo Boost Max Technology 3.0 uses a driver coupled with information stored in the CPU. It identifies and directs workloads to the fastest core on the die first. The driver also allows for custom configuration via a whitelist that enables end users to set priority to preferred applications. The driver MUST be present on the system and configured correctly, as current operating systems cannot effectively route workloads to ordered cores.

Is Intel® Turbo Boost Max Technology 3.0 enabled automatically or do I need to install it?

Intel® Turbo Boost Max Technology 3.0 requires you install and enable BIOS support, driver, and software applications.

What is the difference between Intel® Turbo Boost Max Technology 3.0 and Intel® Turbo Boost Technology 2.0?

Intel® Turbo Boost Max Technology 3.0 allows for higher frequencies with single-core turbo when compared to Intel® Turbo Boost Technology 2.0.

How does the Intel® Turbo Boost Max Technology 3.0 software work?

The software user interface and driver allow users to prioritize programs by directing workloads to the fastest core first.

Error Messages

The following error popup displays for the cases mentioned below:

 
  • Case 1

    The BIOS didn’t recognize the device ID ACPI\INT3510 in the Device Manager. In this case, the Intel Turbo Boost Max Technology 3.0 driver is not available, so it prompts the error popup. As shown in the Device Manager screen below, the Intel Turbo Boost Max Technology 3.0 device is not listed:


    BIOS didn’t expose the device id “ACPI\INT3510”

    Resolution
    You can resolve this issue with the correct BIOS to expose the device ID ACPI\INT3510. Refer to your motherboard vendor for BIOS information.


     
  • Case Two

    BIOS exposed the device ID ACPI\INT3510. We observe the device listed in the Device Manager, but the driver for the device is not installed. In this case, the Intel Turbo Boost Max Technology 3.0 driver is not available, so it prompts the error popup. As seen below, the Intel Turbo Boost Max Technology 3.0 device is listed as Unknown device:


    ITBM device is listed under unknown device

    Resolution
    You can resolve the issue by installing the Intel Turbo Boost Max Technology 3.0 driver.

Software Configuration and Setup 
Overview

Processors with the Intel® Turbo Boost Max Technology 3.0 feature contain at least one processor core with a maximum turbo frequency higher than the other cores. Targeted applications must run on the higher frequency core for maximum performance benefits.

Intel® Turbo Boost Max Technology 3.0 Application / Driver directs targeted application software to run on the higher performance processor cores. You can configure the directive.

After installation, the Intel® Turbo Boost Max Technology 3.0 Application / Driver automatically loads when the system starts. The application is initially minimized to the notification area. To access the icon in the notification area, right-click and select the Show UI control. You can enable, disable, quit, or close the application entirely.

Main Window

The Intel® Turbo Boost Max Technology 3.0 Application displays one main window with controls shown and described below:

Enable

You can configure targeted applications on processor cores ordered on the Core List. When you check the Enable box (default setting), the software runs the demanding work based on the Core List.

Demanding work is defined as targeted application software for which processor utilization exceeds a configured utilization threshold (Intel default = 90%). You can change the threshold in the Advanced Settings.

When the box is unchecked, the software returns the system to normal OS operation, which may not provide the best performance.

In some cases, external software may disable the Intel® Turbo Boost Max Technology 3.0 Application / Driver. The application displays (External Control Active) to the right of the Enable control. The application may disable even when you have checked the Enable box.

Foreground App Has Priority

When the box to the left of the Foreground App Has Priority control is:

  • Checked (default): the in-focus application becomes a targeted application. The application takes priority over any other targeted applications in the Turbo Boost Max Applications list. It has priority demanding work from the Core List.
  • Unchecked: application priority goes from top to bottom in the Turbo Boost Max Applications list.
Turbo Boost Max Applications

The box below Turbo Boost Max Applications lists the targeted applications that demand work from the Core List when you check the Enable box. The list is in priority order, with top priority targeted applications at the top. Use the Add App control to browse, select, and add targeted applications to the list. You can also drag and drop to add targeted applications.

To change the list order, right-click a targeted application name and select a control from the displayed dialog box. Select Move Up to move the targeted application towards the top of the list or Move Down to move it towards the bottom. Select Delete to delete the list entry.

Core List

The Core List is an ordered list of the number of the cores that the processor support. The highest performance core is at the top. Adjacent list entries may represent cores with equivalent performance. The core numbering scheme is consistent with the core numbering scheme of the operating system. For example, Core 0 corresponds to logical processors 0 and 1, and Core 1 corresponds to logical processors 2 and 3.

Note When per core maximum ratio over clocking is occurring, - Overclocking Enabled! displays to the right of Core List.
Profile

A Profile allows you to save Intel® Turbo Boost Max Technology 3.0 Application software settings so you can restore them at a later time. You can use the + and - buttons to add and remove profiles. You can save profiles by selecting the Apply button.

Apply and Cancel

When a change is made to any control, the Apply and Cancel controls change color to indicate a pending change. To save the change, select the Apply control. To cancel changes, select the Cancel control.

Advanced Settings

To access the Advanced Settings window:

  1. Left-click the icon in the upper right portion of the display below the close control.
  2. Select the Settings control. The Advanced Settings window contains a small number of controls shown and described below:

Evaluation Interval

The Evaluation Interval advanced setting controls how often the Intel® Turbo Boost Max Technology 3.0 Application / Driver looks for demanding work. The measurement of the interval is in 100 millisecond units. The default value is 10 (once per second).

Utilization Threshold %

Demanding work is work for which percent processor utilization over the period specified by Evaluation Interval exceeds a threshold specified by this advanced setting (default is 90%).

Caution
Setting a low Utilization Threshold value (for example, < 30%) may degrade system performance. It can adversely impact the benefit of Intel® Turbo Boost Max Technology 3.0 performance.
Affinitize All Demanding Work

When the box to the left of the Affinitize All Demanding Work advanced setting is:

  • Checked (default): the software runs the demanding work of all applications on processor cores listed in the Core List. Application priority:
    1. Foreground Applications (if you check the Foreground App Has Priority control)
    2. Applications in the Turbo Boost Max Applications list
    3. Other applications
  • Unchecked: the software runs the demanding work of Foreground Applications (if you check the Foreground App Has Priority control) and applications in the Turbo Boost Max Applications list only.
Affinity Controls button selection options:
  1. Affinitize To All Cores
  2. Affinitize Only To Cores With Diversity
Affinity Controls specify whether the Intel® Turbo Boost Max Technology 3.0 Application / Driver places demanding work in priority order on all cores listed or on higher performance (diverse) cores. Placing demanding work on higher performance cores results in OS scheduler policy placing work on the residual cores. The default setting is Affinitize To All Cores.

When a change is made to any Advanced Settings control, select the OK control to save the changes. To cancel changes, select the Cancel control.
 
Note Manufacturers may tune default control values for a specific platform. Controls may be initially different than documented above.
