How to disable intel turbo boost on a laptop. Processors. Checking the operation of the mode

Few owners of computers with i5 and i7 processors know that these “hearts” can briefly operate above their factory frequency, that is, faster.

This is achieved through special technology from Intel, which, if installed all correct drivers enabled and running by default. Let's check it and look at this work - it will help us with this Turbo Boost technology monitor.

Briefly about Turbo Boost technology

As you understand from the above, this technology allows you to overclock the processor frequency above the nominal value set at the factory for a short time. This happens absolutely safely, because voltage, current, temperature and even the state of the operating system are taken into account.

The duration of this acceleration depends on the operating conditions, type of workload, number of active cores, and platform design. Computer performance can increase very noticeably and significantly.

All this is wonderful, of course, but there is a small fly in the ointment - this technology does not support all processors, but only the first three generations of i5 and i7...

Checking the operation of Turbo Boost

The Turbo Boost technology monitor for older i5 and i7 processors has already been removed from the official resources of Intel, but the installer continues to “walk” on the Internet - I will provide a link to it at the end of the article.

Let's check how Turbo Boost works or find out whether this technology is actually used on our computer?

Installing the monitor is quick and easy. We launch it and get such a widget on the computer screen. Click on it with the right mouse button and select the size...

...you can also attach it here on top of all windows so that you can observe the operation of the technology, for example, when launching any computer programs.

The frequency of my processor set from the factory is 2.3 GHz. Just by moving the mouse and opening and closing several windows, I “caught” the moment of processor acceleration with my screenshot...

After making sure that everything was working as it should, I removed the Turbo Boost technology monitor, which I advise you to do as well.

Simply put, Turbo Boost is the ability to increase the frequency of one or more actively used processor cores at the expense of the rest that are currently not in use. Unlike banal overclocking (for example, by changing the frequency multiplier in the BIOS), Turbo Boost is an intelligent technology.

Firstly, the increase in frequency occurs depending on the current load of the computer and the nature of the tasks being performed. For example, for fast operation of single-threaded applications, it is important to speed up one core as much as possible (others are still idle). For multi-threaded tasks, you will need to “boost” several cores.

Secondly, unlike the same overclocking, Turbo Boost remembers the limitations of power, temperature and current as part of the design power (TDP, thermal design power). In other words, overclocking using Turbo Boost does not go beyond the normal operating conditions of the processor (all these indicators are constantly measured and analyzed), does not threaten overheating and, therefore, does not require additional cooling.

System Turbo Boost operating time varies depending on workload, operating conditions, and platform design.

Overclocking subtleties

Let’s immediately make a reservation that frequency changes using Turbo Boost technology occur discretely. The minimum unit for increasing or decreasing the frequency of one or more active cores is a step, the value of which is 133.33 MHz. Please note that the frequency for all active cores changes simultaneously and always by the same number of steps.

Let's look at how Turbo Boost technology works using the following example.

Currently, a quad-core processor has two active cores and their frequency needs to be increased. The system increases the frequency of each of them by one step (+133.33 MHz) and checks the current, power consumption and temperature of the processor. If the indicators are within the TDP, the system tries to increase the frequency of each of the active cores one more step until it reaches the set limit.

If increasing the frequency of each of the two active cores by one more step (+133.33 MHz) causes the system to go beyond the standard thermal package (TDP), the system automatically lowers the frequency of each core by one step (-133.33 MHz) to return normal condition. As mentioned above, you cannot change the frequency of active cores individually. That is, in principle, it is not possible for the frequency of one active core to change by one step, and the frequency of another - by two steps.

Turbo Boost technology is supported by desktop and mobile Intel Core i5/i7 processors, but different models may have different operating modes. For example, the following operating modes exist for Intel Core i5 600 series and Core i7 900 series for mobile and desktop processors, as well as Core i7 Extreme Edition.

Turbo Boost is Intel's proprietary automatic computer technology. In this mode, it exceeds the nominal performance indicators, but only up to the “critical” level of heating temperature limits and consumed power.

Features of activating turbo mode on laptop PCs

Laptops can operate from two sources: mains power and batteries. When powered by a battery, the OS, to increase operating life (by default), “tries” to reduce energy consumption, including by reducing (CPU). Therefore, turning on turbo mode on a laptop has a number of features.

In older device BIOS models, there were options to enable and configure this mode. Nowadays, manufacturers are trying to minimize the possibility of user intervention in the operation of the CPU, and often this parameter is missing. There are two ways to activate the technology:

Through the operating system interface.
Via BIOS.

How to enable Turbo Boost through the Windows interface

You can influence the turbo mode state by setting the required values in the “Minimum processor state” and “Maximum processor state” parameters in the current power consumption plan:

In the next section, click on the “Change advanced power settings” link.
In the drop-down list of the “Power Options” dialog we find the “CPU Power Management” item.

Activate turbo mode via BIOS

This option to enable Turbo Boost on a laptop is suitable for advanced users. It is based on resetting all settings in the BIOS to default values:

Let's go to the BIOS.
At the end of the menu we find the “Load Default” section.
Reset all settings.

To monitor the turbo mode status, you can use the utility Intel Turbo Boost Technology Monitor.

Turbo Boost is an Intel proprietary technology for automatically “overclocking” the computer’s central processor. In this mode, the CPU clock speed exceeds rated performance, but only up to the “critical” level of heating temperature and power consumption limits.

Turbo Boost Technology

Intel Core I5 and I7 processors, in addition to the established nominal frequency, can operate at higher speeds. This speed is achieved thanks to special Turbo Boost technology. When all drivers are installed, this technology is enabled and works by default. However, if you have installed all the software and there is no acceleration observed, it is worth monitoring Turbo Boost.

What is Turbo Boost and how does it work?

Turbo Boost is a technology that is designed specifically for Intel Core I5 and I7 processors of the first three generations. It allows you to temporarily overclock the core frequency above the established nominal. Moreover, such overclocking is performed taking into account the current, voltage, temperature of the device and the state of the operating system itself, that is, it is safe. However, this increase in processor speed is temporary. It depends on operating conditions, load type, number of cores and platform design. In addition, overclocking using Turbo Boost is only possible for Intel Core I5 and I7 processors of the first three generations. The full list of devices that support this technology is as follows:

It is also worth noting that Turbo Boost technology only works on Windows 7 and 8 operating systems. Windows Vista, XP and 10 do not support this technology.

How to check if Turbo Boost is working?

In order to check whether Turbo Boost is enabled and working, Intel developers have released a special utility “Turbo Boost Technology Monitor”. The operation of this program is simple:

Turbo Boost.exe download for free:

Size: 23 MB | Downloaded: 2247 times | File type: exe | Version: 07/06/16

Download the Setup.exe file and run it on your PC. Follow the instructions of the installer wizard.

A new program window will open. Below is the nominal core frequency.

If you turn on some program or even a video in good quality, you will see how Turbo Boost works.

If the technology does not work, but your processor supports it, you should enable it.

How to enable Turbo Boost?

There are two ways to enable Turbo Boost technology:

Via BIOS;
Through the Control Panel of the operating system.

In the first case, in the BIOS, in the “Load Default” section, you need to reset all settings. As for activating the mode through the Control Panel, to do this you should follow these steps:

Click “Start”, “Control Panel” and select “Power Options”.

In the new window, check the “Balanced mode” checkbox and click “Set up power plan.”

In the next window, select “Change advanced power settings.”

In the list we find the item “Processor power management”. For the minimum and maximum processor state we set it to 100%.

After restarting the computer, Turbo Boost mode will be activated.

How to turn Turbo Boost on or off on Mac – News from Ukraine and the world

Almost all modern Mac computers are equipped with processors that support Turbo Boost technology, which controls the clock speed at the request of the operating system. It speeds up your Mac or PC, but activating this feature also increases battery drain. Mac users have the option to enable Turbo Boost to make the computer run faster, or disable it to save energy. A special application has been developed to control Turbo Boost mode, which is compatible with OS X El Capitan, but does not work with macOS Sierra. Using “Turbo Boost Switcher for OS X” requires a modern processor such as Intel Core i5 or Core i7. To control the operation of Turbo Boost, the utility will load and unload kernel extensions.

It's worth noting that "Turbo Boost Switcher for OS X" is intended for advanced users only. Due to the fact that the application makes changes to the system kernel, you must back up your data on your computer before using it.

How to disable Turbo Boost on OS XStep 1: Go to rugarciap website and download Turbo Boost Switcher (free and paid versions available). To run the utility, you need to disable Gatekeeper in the “Protection and Security” section. Step 2: After you launch the application, a corresponding lightning bolt icon will appear in the top line. It opens a drop-down menu for managing the utility. Here you can disable Turbo Boost by selecting the “Disable Turbo Boost” item. Step 3: When prompted by the OS, enter the administrator password (this is required, since the program makes changes to the system kernel).

After turning off Turbo Boost, the operating system will recalculate the remaining battery life. If you use heavy programs, you will probably notice a decrease in performance. It is recommended to disable Turbo Boost only if you need to extend the operating time of your computer away from a power outlet.

How to re-enable Turbo Boost To reset, go to the drop-down menu in the status bar and select "Enable Turbo Boost" and enter the password again. The kernel extension that blocks the feature will be removed. Does disabling Turbo Boost actually improve battery life on your MacBook? Depending on how you use your computer, Turbo Boost can significantly improve your Mac's battery life. But at the expense of overall computing power. In other words, if you turn off Turbo Boost, the laptop's battery life will increase, but the computer will run slower. Whether it's worth sacrificing performance depends on the situation. Sometimes battery life is more important than performance.

Tests of “Turbo Boost Switcher” on a MacBook Pro showed an increase in battery life by about an hour. Some users are talking about more drastic changes. “Disabling Turbo Boost reduces CPU performance by about a third, but for non-resource-intensive tasks the difference is almost unnoticeable. MacBook Pro also heats up significantly less and runs 25% longer,” noted the author of the resource Marco.org.

Technology Intel Turbo Boost allows you to automatically increase the processor clock speed above the rated speed, as long as the power, temperature, and current limits of the TDP specification are not exceeded. This results in increased performance for single-threaded and multi-threaded applications.
