Turbo Boost is Intel proprietary technology for an automatic computer. In this mode, it exceeds the nominal performance indicators, but only up to the “critical” level of the heating temperature and power consumption limits.
Features of activating turbo mode on laptop PCs
Laptops can be operated from two sources: mains power and batteries. When running on battery power, the OS “tries” to reduce power consumption to increase the operating life (by default), including by reducing (CPU). Therefore, turning on the turbo mode on a laptop has a number of features..
In older models, BIOS devices had options to enable and configure this mode. Now manufacturers are trying to minimize the possibility of user interference with 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 state of the turbo mode by setting the desired values \u200b\u200bin the "Minimum processor state" and "Maximum processor state" parameters in the current energy consumption plan:
- In the next section, follow the link "Change advanced power settings".
- In the drop-down list of the "Power supply" dialog, we find the item "CPU power management".
Activating turbo mode via BIOS
This option for enabling Turbo Boost on a laptop is suitable for advanced users. It is based on resetting all settings in BIOS to default values:
- Go to BIOS.
- At the end of the menu, we find the "Load Default" section.
- We reset all settings.
To monitor the status of the turbo mode, you can use the utility Intel Turbo Boost Technology Monitor.
Intel Core I5 \u200b\u200band I7 processors, in addition to the nominal frequency, can operate at higher speeds. This speed is achieved thanks to the 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 you are not seeing any acceleration, you should monitor Turbo Boost.
What is Turbo Boost and how does it work?
Turbo Boost is a technology specifically designed for the first three generations of Intel Core I5 \u200b\u200band I7 processors. It allows you to temporarily overclock the core frequency above the specified rating. In this case, such overclocking is performed taking into account the current strength, voltage, device temperature 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, type of load, number of cores and platform design. In addition, overclocking with Turbo Boost is only possible for Intel Core I5 \u200b\u200band I7 processors of the first three generations. A complete list of devices that support this technology is as follows:
It should also be noted that Turbo Boost technology works only on Windows 7 and 8 operating systems. Windows Vista, XP and 10 do not support this technology.
Technology Intel Turbo Boost allows you to automatically increase the processor clock speed above the nominal, if the power, temperature and specification limiting currents are not exceeded as part of the calculated power (TDP). This results in improved performance for single-threaded and multi-threaded applications.

Intel Core i5 2450M @ 2.5GHz (up to 3.1GHz Turbo Boost) what is Turbo Boost and how to enable it and got the best response
Answer from Angry Birds Space [master]
Rizabek Khalikov you are so funny))
Turbo Boost is a technology from Intel that automatically increases processor clock speeds beyond the rated speed while not exceeding the power, temperature, and current limits as part of the TDP. This results in improved performance for single-threaded and multi-threaded applications. In fact, this is a technology for "self-overclocking" of the processor.

Answer from Master of brilliant green[guru]
Turboboost was created in order to adjust the work of the processor for applications.
Answer from Butt-Head[newbie]
How do I enable Turbo Boost?
It is already enabled by default.
How do I disable Turbo Boost?
To disable, you need to change the maximum state of the processor in the current power plan.
Control Panel -\u003e Hardware and Sound -\u003e Power Options -\u003e Configure Power Plan -\u003e Change Advanced Power Options -\u003e Manage CPU Power:
The maximum state of the processor: from the mains and the battery, set the value below 100 (to disable it, just put 99).
Minimum processor state: also check that the value is below 100.
That is, if it costs 100 - turbo boost is on. If less than 100 - off.
Good afternoon, dear audience. Today we will try to convey to you what a turbo boost is in a processor and for what purposes it is used. We're sure many of you have heard of this technology, but have no idea how it works.
Turbo Boost was developed by Intel for its own chips to optimize the functionality of the chips and add performance to them without the need for overclocking.
Many people think that the technology is applicable to AMD CPUs, but they are mistaken: the red mode is called Turbo Core.
How does it work?
In simple terms, turbo boost mode is an automatic increase in the frequency of active cores due to those that are idle at the time of operation. In contrast to manual overclocking by changing the system bus in the BIOS, the technology under review is intelligent.
The increase is determined by the task being performed and the current load on the PC. In the single-threaded computing mode, the main core is overclocked to the maximum allowable values \u200b\u200bby borrowing the potential of the others (others are still idle). If the entire processor is included in the work, then the frequencies are distributed evenly.
The process also affects cache memory, RAM, and disk space.
Turbo Boost also "remembers" the following system limitations:
- peak load temperatures;
- limiting the heat dissipation of a specific motherboard;
- increasing performance without increasing voltage.
In other words, if your PC is built on a motherboard with a TDP of 95W, and the CPU operates with a current of 1.4V, while the cooling system is boxed (standard), then the turbo boost function will increase the power of the CPU in such a way as to fit into existing limitations. and do not go beyond the temperature range.
Frequency scaling principle
We figured out what the function does. Now let's describe HOW she does it. The procedure is always performed according to a single scenario: the system sees how cores (1 or more) are actively working in the processor and cannot cope with the load, i.e. need to increase the frequency. The boost increases the value of each of them strictly by 133 MHz (step) and checks the following parameters:
- voltage;
- heat pack;
- temperature.
If the indicators do not go beyond the limits, then the system throws another 133 MHz (one more step) and reconciles the indicators. When the permissible TDP is exceeded, the stone begins to reduce the frequency separately on each core by a standard step until it reaches the maximum permissible values.
Differences between Turbo Boost 2.0 and 3.0
While version 2.0 supports a gradual increase in the operating values \u200b\u200bof all processor cores, depending on the tasks being executed, then the newer version 3.0 determines the most efficient cores to maximize their operating frequencies in single-threaded computing.
The second point is CPU support. The second version works on all chips of the Core i5 and i7 family, regardless of generation. The third is supported only by the following chips:
- Core i7 68xx / 69xx;
- Core i9 78xx / 79xx;
- Xeon E5-1600 V4 (for one socket only).
Outcome
If you do not feel the need to overclock your processor on a regular basis, but have an Intel i5 or i7 chip, then you can safely count on intelligent overclocking in work applications and toys, if the system deems this step necessary.
At the same time, you don't have to worry about buying a motherboard with overclocking support, knowing all the subtleties of heat dissipation, as well as issues related to overclocking.
Well, if you are considering a purchase in the near future, then I recommend you this one online shopbecause it is tried and tested and popular).
In the next articles we will try to highlight such a moment as in processors, and the effect of solder on the overclocking capabilities of the system. So build your dream PC.
