How to enable Turbo boost on a laptop. How do I check Turbo Boost Technology? How to check if Turbo Boost is working

When communicating with users, I began to notice that many do not understand at all what Turbo Boost is, what the purpose of turbo acceleration of processors is, and what kind of gain can be obtained from it. Also, many people confuse turbo acceleration with hypertrading, although these are completely different technologies. Let me remind you that Turbo Boost technology was introduced with the release of the first generation of i3, i5, i7 processors; Intel and the Xeon processor line were not ignored. Hypertrading technology began to be implemented on Intel Xeon processors in November 2002, in i3-i5-i7 with the release of the first generation of this line.

Turbo Boost Intel processors

Turbo Boost- literal translation of turbo boost (turbo overclocking, turbo acceleration) - Intel technology for automatically increasing the processor clock frequency above the nominal, if the power, temperature and current limits in the design power (TDP) are not exceeded. This results in increased performance for single-threaded and multi-threaded applications. In fact, this is a technology for “self-overclocking” the processor.

And it becomes completely incomprehensible to me when beginners, and sometimes even experienced fans of overclocking processors, disable this function in order to ultimately increase the processor clock frequency, which will not give a significant increase. The availability of Turbo Boost technology is independent of the number of active cores, but is dependent on the presence of one or more cores operating below their rated power. System Turbo Boost operating time varies depending on workload, operating conditions, and platform design.

Intel® Turbo Boost Technology is usually enabled by default in one of the BIOS menus. As we know, overclocking a processor by increasing the processor clock frequency is possible only on motherboards with a “Z” chipset, but not all users know that it is possible to speed up performance on chipsets with the index “B” and others. In this case, of course, we do not have full control over the values, but increasing the processor multiplier is better than raising the lower threshold Turbo BoostWe are quite capable, which gives a noticeable increase in the speed and responsiveness of the operating system itself, which is sometimes very useful. Since the upper value does not change, you should not expect an increase in heavy renderings, renderings, games, the time of these calculations will remain at the same level. I will give an example on my GA-B75-D3H motherboard and i5 3570 processor, since the appearance and location of some BIOS tabs may differ depending on the model and manufacturer.

To increase the multiplier parameter, you need to go to the BIOS during boot by pressing the “DEL” button.

Go to Advanced Frequency Settings

And change the multiplier parameter to the maximum; this parameter is individual for each processor model. Changing the multiplier is done using the “Page UP” and “Page Down” keys. For example, on my i5 3470 with operating frequencies of 3.4 - 3.8 GHz, the maximum permissible multiplier is 3.60, and from personal experience, increasing the frequency from 3.40 to 3.60 makes the OS noticeably more responsive and faster. Programs launch faster, and moments of thoughtfulness of the system also disappear, but I repeat once again that this will have almost no effect on rendering or FPS in games, since the maximum frequency and multiplier remain at the same level, in my case it is 3.80 GHz and 36.

To increase the impact on performance, you can go to “Advanced CPU core settings” and change the number of cores to the maximum. In my case it is 4 cores. This parameter disables the power saving mode and all cores will always be used for work; in the “Auto” mode, the number and load on the cores is selected automatically and for some tasks only 1 or 2 cores can be used and only at maximum loads the thread can be distributed to all cores.

I would like to note that this method of increasing performance is absolutely safe for the processor and other components of your PC, which I consider the most important fact.

Hypertrading of Intel processors

Hyper-threading- hyperthreading, official name - hyper-threading technology, HTT or HT- technology developed by the company Intel for processors based on NetBurst microarchitecture. HTT implements the idea of "simultaneous multithreading" (eng. simultaneous multithreading, SMT). HTT is a development of superthreading technology. super-threading), which appeared in processors Intel Xeon in February 2002 and November 2002 added to processors Pentium 4. Once HTT is enabled, one physical processor (one physical core) is recognized by the operating system as two separate processors (two logical cores). For certain workloads, using HTT can increase processor performance. The essence of the technology: transfer of “useful work” to inactive actuators.

HTT is not implemented in series processors Core 2(“Core 2 Duo”, “Core 2 Quad”).

In processors Core i3, Core i7 and some Core i5 a technology similar in its principles was implemented, which retained the name hyper-threading. When the technology is enabled, each physical processor core is defined by the operating system as two logical cores.

It is worth noting that not all models of Intel i3, i5, i7 and Xeon processors are equipped with this multi-threading technology; before purchasing, read the specifications carefully so that this does not come as a surprise to you.

Processor supporting technology hyper-threading:

can store the state of two threads at once;
contains one set of registers and one interrupt controller (APIC) for each logical processor.

For the operating system, this looks like having two logical processors. Each logical processor has its own set of registers and an interrupt controller (APIC). The remaining elements of the physical processor are common to all logical processors.

Let's look at an example. The physical processor executes the instruction stream of the first logical processor. The command stream is suspended for one of the following reasons:

a miss occurred when accessing the processor cache;
an incorrect branch prediction was made;
the result of the previous instruction is expected.

The physical processor will not remain idle, but will transfer control to the command stream of the second logical processor. Thus, while one logical processor is waiting, for example, for data from memory, the computing resources of the physical processor will be used by the second logical processor.

Unfortunately, Hypertrading does not provide gains when performing all tasks. So in some games, disabling this function will not affect FPS in any way. When performing heavy calculations, such as 3D rendering, video editing, video conversion and the like, the increase will be very significant. This is why Mac PRO computers are equipped with Intel Xeon processors with support for hypertrading technology, since this is the best option for maximum performance. But in games, these processors show far from such brilliant results, but as you know, the Mac PRO is the original workhorse and it is not particularly designed for toys; for games you can use an iMac or MacBook.

I hope I was able to convey to you something useful and now you will not confuse these technologies. Good luck!

The frequency of a processor determines the number of operations it can perform in one second, but the higher the frequency, the more power the processor consumes and the greater the load on its components. Therefore, the processor does not constantly maintain the same frequency. Under heavy load, the frequency increases, and without load, it decreases back. Naturally, the increase in frequency is limited.

Turbo Boost technology works in a similar way, only it increases the frequency well above the base maximum. For example, if the base frequency of the Ryzen 3600 is 3.6 GHz, then in Turbo Boost it can operate at 4.2 GHz.

By default, Turbo Boost support is already enabled and if you haven't changed anything in your BIOS settings, then everything should work. In this article, we will figure out how to enable Turbo Boost Ryzen, in case you accidentally disabled it.

How to enable Turbo Boost on Ryzen

I will perform all actions on the MSI motherboard; other motherboards will do the same. Restart your computer and press several times Del, F2, F8 or Shift+F2 to enter the BIOS setup menu. Here go to the OS section and open the Advanced item. There are two parameters here: CPU Ratio And Core Performance Boost:

Using the CPU Ratio parameter we can overclock the processor. A multiplier is specified here, on the basis of which the processor frequency will be determined. By default, the Ryzen 5 2600 uses a multiplier of 36 and its frequency is 3.6 GHz, it can be increased to 40 to increase the frequency to 4 GHz. However, as soon as you change the value of this parameter, Turbo Boost will stop working. Now you control your processor yourself.

To enable Turbo Boost Ryzen, return to settings CPU Ratio and Core Performance Boost Auto value. Then save the settings and restart your computer. After this, the turbo boost will work again. Modern processors are quite powerful and in most cases there is no point in overclocking the processor; Turbo Boost can handle this; you can only overclock the memory a little.

Also, so that Windows does not interfere with your processor’s normal operation, you need to change the default power scheme. Balanced mode for Ryzen is very often used; instead, you should choose the usual balanced one. To do this, open Search and dial Selecting a power plan:

Click on the diagram here Balanced and save the changes. If there is no such diagram, open the arrow Additional schemes.

Power settings

The first thing I recommend doing is paying attention to the power supply. The fact is that the default settings on most laptops are set to "optimal" device performance (that is, often aimed at saving energy so that the device can last longer on battery power). At the same time, if the processor power supply is set to low, the function will be automatically disabled (which will seriously affect performance).

First, pay attention to the system tray: there should be a “battery” icon there. By clicking on it with the left mouse button, you can see a window in which there is a “performance” slider, move it to maximum.

To find out if Turbo Boost technology is being used your laptop, you need to install one of the special. utilities:

There is a special on the official website. monitor to monitor processor performance (see screenshot below, left). If your CPU performance "jumps" above the dark blue mark (in the example below 2.5 GHz) - then Turbo Boost is supported. To test, start some game/watch a movie, etc.
- in the main program window (CPU tab) pay attention to the parameter Core Speed(the frequency there will constantly change, but its maximum should reach the value that we saw in the CPU specification, in the Max Turbo Frequency column, i.e. 3.1 GHz or 3100 MHz, which is the same thing (see screenshot below and higher)).

Does Turbo Boost work on a laptop (clickable). Monitor from the Intel website and the utility (on the right) CPU-Z

Why Turbo Boost may not work(*if supported by your CPU):

due to power settings (be sure to set the CPU power to 100%, see the first step in the article);
missing drivers ();
the technology can be disabled in the BIOS/UEFI (see screenshot below, Turbo Mode).

High temperature, overheating

Another fairly popular reason for decreased performance in laptops is overheating. The fact is that when the processor temperature reaches a certain point, it begins to reduce its performance (to lower the temperature). If the temperature continues to rise and reaches a critical point, the device turns off. Modern two-level protection (you may have already heard this term somewhere).

By the way, the critical processor temperature, upon reaching which the laptop will turn off, is indicated in the specification on the Intel website (see the “T junction” column).

In general, in general, it is highly undesirable for the processor temperature to exceed 70 C.

It is not uncommon for performance to deteriorate due to the fact that in addition to the game that the user launched (say), some third-party “heavy” applications are running on the laptop. It is not uncommon for users to catch mining viruses (which have become popular recently).

First, I recommend opening task manager (combination Ctrl+Shift+Esc) and sort applications by CPU load. It’s not uncommon for “unclear” processes to load the system (I'm not even talking about the fact that sometimes the CPU is loaded, but the dispatcher may not show what...).

Not optimal video driver and game graphics settings

Because Many people are most often dissatisfied with performance in games - this topic has been included in a separate subsection of the article.

Most users do not believe that just by setting the settings of the video driver and the game itself, you can significantly increase the number of . I note that sometimes FPS increases by 100% or more!

The first thing I recommend is optimizing your video driver settings. Those. set the highest performance and disable some “effects” (this can be done by going to the video driver settings and activating the advanced user mode).

I already have 3 articles on my blog on setting up video cards from Intel, AMD, nVidia. To avoid repetition here, here are the links:

AMD - https://site/kak-uskorit-videokartu-amd-radeon.html
nVidia-
Intel HD -

In addition, pay attention to the graphics settings in the game itself. Particular attention to:

resolution (the higher it is, the greater the load on the video card; when it decreases, the number of FPS increases);
graphics quality;
detailing;
effects and shadows (if any).

Not an optimized system

And I can’t help but note in this article that you can slightly increase the performance of your laptop by optimizing Windows. As a rule, it includes several stages:

Disabling services: some of them are simply not needed by many, and they take up resources;
Cleaning the registry, deleting junk files (over time, many people accumulate tens of gigabytes of junk files that affect performance);
Disk Defragmenter(relevant for HDD, SSD does not need to be defragmented);
Setting up Windows startup(it’s no secret that as new programs are installed, the system’s startup “expands”; moreover, you can use many startup software very rarely, and it will take up time every time you turn on the PC. Is it necessary?!);
Updating old drivers;
Enabling performance// in Windows settings
Disabling indexing files on disk.

How to do all this (step by step and without the risks of “ruining” something) is described in this article:

That's all for now...

All the best!

Intel Core i5 2450M with a frequency of 2.5 GHz (up to 3.1 GHz in Turbo Boost mode) what does Turbo Boost mode mean and how to enable it and received the best answer

Rizabek Khalikov you are so funny))
Turbo Boost is Intel's technology for automatically increasing the processor clock speed above the rated speed while staying within the power, temperature, and current TDP limits. This results in increased performance for single-threaded and multi-threaded applications. In fact, this is a technology for “self-overclocking” the processor.

it turns on itself. it's like auto acceleration

Answer from Ale3x[active]
should turn on itself if processor resources are not fully used

Answer from Alexander[guru]
Intel® Turbo Boost Technology is usually enabled by default in one of the bios menus. Other than using the BIOS menu, there is no way for the user to change the operation of Intel® Turbo Boost Technology through hardware or operating system settings. When Intel® Turbo Boost Technology is enabled, it runs automatically under the operating system.

Turboboost was created to adjust the operation of the processor to applications.

Answer from Butt-Head[newbie]
How to enable Turbo Boost?
By default it is already enabled.
How to disable Turbo Boost?
To disable it, you need to change the maximum processor state in the current power plan.
Control Panel --> Hardware and Sound --> Power Options --> Set up power plan --> Change advanced power settings --> Manage processor power:
Maximum processor state: set the value below 100 from the mains and battery (to disable it, just set it to 99).
Minimum processor status: also check that the value is below 100.
That is, if it costs 100, turbo boost is turned on. If less than 100, it is turned off.

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 operating time in Turbo Boost mode 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.
