How to find out the clock speed of a computer. What is the processor clock speed and what should it be?

The performance and speed of the system greatly depends on the clock frequency of the processor. This indicator is not constant and may change slightly during computer operation. If desired, the processor can also be “overclocked,” thereby increasing the frequency.

You can find out the clock frequency as follows: using standard methods, and using third-party software (the latter gives a more accurate result).

It's worth remembering that clock frequency The processor speed is measured in hertz, but is usually specified in either megahertz (MHz) or gigahertz (GHz).

It is also worth remembering that if you use standard methods of checking frequency, you will not see such a word as “frequency” anywhere. You will most likely see the following (example) − « Intel Core i5-6400 3.2 GHz". Let's look at it in order:

1. "Intel"- these are the names of the manufacturer. Instead there may be "AMD".
2. "Core i5" is the name of the processor line. Instead, you may have written something completely different, however, this is not so important.
3. "6400"— model of a specific processor. Yours may also differ.
4. "3.2 GHz" is the frequency.

The frequency can be found in the documentation for the device. But the data there may differ slightly from the real ones, because... The documents say the average value. And if any manipulations were performed with the processor before, the data may differ dramatically, so it is recommended to obtain information only by software.

Method 1: AIDA64

– functional program for working with computer components. The software is paid, but there is a demo period. In order to view data about the processor in real time, it will be quite enough. The interface has been completely translated into Russian.

The instructions look like this:

Method 2: CPU-Z

– a program with easy and clear interface, which allows you to view in more detail all the characteristics of the computer (including the processor). Distributed free of charge.

To see the frequency, just open the program and in the main window pay attention to the line "Specification". The name of the processor will be written there and at the very end the current frequency in GHz will be indicated.

Method 3: BIOS

If you have never seen the BIOS interface and do not know how to work there, then it is better to leave this method. The instructions look like this:

Method 4: Standard system tools

Most easy way of all, because does not require installation of additional software or entering BIOS. Find out the frequency standard means Windows:

Finding out the current frequency is very easy. IN modern processors this indicator is no longer the most important factor in terms of productivity.

The system unit is one of the main elements of a computer, which allows you to read and convert information. It also determines which programs, games, and operating systems will be supported on your device. A processor (SP) has several main characteristics: number of cores, frequency and model. It is especially necessary to monitor its temperature, since overheating will lead to breakdown, which is often impossible to eliminate. Another important factor is managing the processor's power settings. On Windows, this is not too difficult to find out, but first you need to understand the characteristics of the device.

How to find out all the information about the processor in Windows

There are several ways to find out the frequency, number of cores and processor model without resorting to the help of third-party programs.

Using Computer Properties

While in Explorer, open the computer properties by clicking on the “My Computer” section right click mice.

Open computer properties

In the “System” block, find the “Processor” line, which will contain all necessary information about your power supply.

Let's look at the basic information about your system

Using the command line

Using search bar Windows, open a command prompt.

Open the command line

Write the systeminfo command and execute it.

Execute the command

After detailed information about your computer appears on the screen, find the Processor line, and in it - bit depth, frequency and other necessary data about the device.

Let's look at the characteristics system unit

Using BIOS

This method is suitable for cases when it is not possible to log in to the system for some reason.

Start turning on the device.

Turn on the computer

As soon as the first signs of system startup appear on the screen, press one of the buttons to enter the BIOS: Del, F2, F Which one to use depends on which company owns your computer and its components. To enter BIOS or Boot Menu Other buttons may be used and are usually specified during system startup.

Entering the BIOS

On home page BIOS in the Processor Type block you can find information about the number of cores of your processor, the frequency at which it operates, and its model.

Finding information on the system unit

Find out what the temperature of the processor is

If your computer constantly turns off on its own or slows down, the reason for this may be an overload of the system unit, which leads to its overheating. To make sure that the heating is higher permissible norm, you need to look at the processor temperature. How to do it:

The easiest way is to use a third-party program that can be downloaded for free on the Internet. For example, you can use the Core Temp application (http://www.alcpu.com/CoreTemp/ - official website of the developer).

Download the application

In the main program window you can find detailed information about the processor itself, as well as separate data on the temperature of all its cores. Normal temperature considered to range from 30–40 degrees Celsius at normal mode work and 70–80 degrees at heavy loads. If you see that your power supply is overheating too much, then you need to address this problem before it burns out.

We look at the temperature of the cores

Computer power settings in Windows 7

If you want to increase the power of your device to run more demanding programs and games, then one option to do this is to change the power settings. Please note that changing the settings towards increasing the load can lead to overheating or rebooting and, ultimately, equipment failure. Therefore, if you decide to take this step, always carefully monitor the state of the processor and try not to load it beyond what it was designed for.

Open your computer's control panel.

Opening the control panel

Go to the Power Options section.

Open the “Power Options” section

Activate the "High Performance" option.

Select the “High Performance” mode

Go to mode settings.

Now you need to set following settings to optimize the power supply as much as possible:

Minimum number of cores idle: 99%.

Enable Power Down States: On.

Disable idle state: Enable idle state.

Minimum condition of P.: 0%.

System cooling policy: Active.

P performance kernel suspend kernel override: Enabled.

Maximum P. condition: 100%.

Maximum number of cores in idle state: 100%.

You can also select other processor power settings to customize its operation for yourself.

Monitor your processor carefully, do not overload it. Don't forget that the system unit, like other computer components, must be manually cleaned of dust to reduce the chance that it will start to overheat. If you overclock your processor, be prepared for its performance to decrease, not increase.

Processor clock speed - this is the number of oscillations over a certain period of time(V in this case- in a second). If we talk about a personal computer, then for it this is an indicator of the number of operations that the processor can perform in 1 second. Remember: the higher the clock speed, the higher the performance of the computer.

What varieties are there?

This is interesting! The unit of measurement of frequency is called the “hertz,” and it is named after the legendary German physicist Heinrich Rudolf Hertz, who in 1885 conducted a unique experiment to confirm the correctness of the electromagnetic theory. The scientist proved that light is a type electromagnetic radiation, which propagates in the form of special waves.

Experts distinguish 2 types of clock frequencies.

1. External (affects data exchange between the board random access memory and processor).
2. Internal (affects the correctness and speed of operation inside the processor).

Another interesting fact is that until 1992, these two indicators, as a rule, coincided, and only as a result of the introduction of new technologies by specialists famous company Intel's internal frequency has been increased by 2 times compared to the external one. An example of such an achievement was the 80486DX2 processor, unique at that time. The manufacturer presented to the public 2 types of such a processor: one is less powerful (25/50 MHz), the other is with higher performance (33/66 MHz). This invention gave a serious impetus, including to other manufacturers, and they began to actively develop and produce processors with noticeably more power.

It is worth paying attention to this important point: The processor clock speed is not the only criterion for assessing the speed and performance of a computer. You also need to take into account the size of the cache memory and . On some processors latest generation used special system responsible for auto increase clock speed of the processor cores. So, if you are an active gamer and cannot imagine your life without daily immersion in the fascinating world of complex games, both in plot and graphics, then you need. But for classic office work, a modern PC is also suitable.

How is the clock frequency determined?

As is known, clock oscillations are formed as a result of the action of a quartz crystal located in a special container. This device is called a “clock resonator”. The crystal begins to work only after voltage is applied and an electric current oscillates. Next, these oscillations are fed to a clock generator, as a result of which the electric current oscillations are converted into pulses, and they are already transmitted to the data buses.

Remember that it is the clock generator that is responsible for the required clock cycle of all PC components, including buses, RAM and, of course, the central processor. If the clock generator is working correctly, all components will also function as synchronously and smoothly as possible.
There is also such a thing as a clock period.

The clock period is the minimum unit by which the operating time of a processor is measured.

Increasing frequency by overclocking

When interacting with the RAM board, the processor usually spends more than one clock cycle. This indicator can be increased artificially, that is, as a result of the so-called “", but having chosen this path, you need to know about some restrictions:

• processor starts consume significantly more energy, and the installed and operated power supply may not be able to cope with this point, so it is worth purchasing a more efficient model;
• as a result of “overclocking,” the amount of energy emitted by the crystal increases, that is, both it and other components will heat up faster(only the efficient system cooling);
• If the volume of supplied electricity increases, problems will certainly arise. electromagnetic interference, in particular, in the operation of data buses (this can lead to a decrease in the amount of data transferred).

How to find out the processor frequency of your computer?

There are four main ways to find out the clock speed and thus determine the performance of a PC:

1. View the documentation provided by the manufacturer along with your computer or laptop. The technical data sheet must indicate the type of processor and its clock frequency. If there is no inscription regarding the clock frequency next to the specified processor model, you can find it out by entering any search engine processor name, laptop model, etc.
2. You can find out the clock frequency by reading the properties of your PC system. What do I need to do? First, go to the “Control Panel”; secondly, go to the “System Properties” section. This section displays computer performance indicators, including clock speed.
3. Take advantage of the opportunities, which you can enter by following some simple rules (for personal computers they are one, for laptops - others). The main thing is to press one “magic” button (for example, Del, Esc or F12) before the system starts booting.
4. Install the CPU-Z utility on your computer, which is absolutely free, and its main purpose is to help the user find out everything he needs Contains information about the processor, including its performance and clock speed.

So, you already know what the clock frequency of a personal computer or laptop is, what significance these indicators have for the speed of the equipment, you know how to determine the frequency, and we hope that this information will help you become an even more professional and successful PC user.

Instructions

However, behind each conditional rating there is a completely normal clock speed. Currently, there are two main competitors in the processor market: Intel and AMD. Each of them has its own line of processors and its own designations. And although manufacturers no longer hide the truth frequency processor, if it is not named, it can be found on the manufacturers’ websites http://www.intel.com And http://www.amd.com.

If the processor is already installed in the computer, then see it frequency possible when turned on. If, when turned on, the computer shows the motherboard logo, you need to press Tab and the POST screen will appear, on which the model is visible processor. True, not all BIOS versions display it frequency.

Find out more frequency processor You can right-click on “My Computer” and select “Properties”. In the “General” tab you can see the type processor and him frequency.

However, the most complete information about the processor can be obtained by downloading a small free program CPU-Z from the manufacturer's website . Download the archive and unpack it. The program does not require installation, just run the cpuz.exe file and you will receive comprehensive data about your processor. Here you can see not only the clock frequency and model name, but also core type, revision, supply voltage, technological process by which the processor was manufactured, number of cores, supported instructions, frequency buses, cache size and much more. In addition, the program provides complete data about motherboard, memory and .

Besides CPU-Z information You can also find out about the processor using other diagnostic programs, such as SiSoft Sandra, Aida, Everest, etc.

Not always the number indicated on the label processor, reflects its clock frequency. Manufacturers often indicate this parameter not in megahertz at all, but in special units that only they understand, and the result in them is deliberately overestimated. VIA is especially guilty of this.

Instructions

You can find out what frequency the processor is actually running at by going to the CMOS Setup utility. To do this, immediately after turning on or restarting the computer, start pressing the “Delete” or “F2” key repeatedly (depending on the type of motherboard). Continue pressing this key until CMOS Setup starts. Select "Frequency/Voltage Control" from the menu. Among the information displayed, you will also see the processor frequency. Do not change the values ​​of any fields in this section unless you know what they mean and what the consequences of changing them may be. Now press the "Escape" key twice and then "Y" and your computer will start up as normal.

If you use the Memtest86+ program to test RAM modules, you can also use it to find out the exact frequency at which the processor operates. It appears on the left top corner screen.

In the operating system Linux information The processor clock speed is displayed on the screen during boot. If you haven’t had time to read it, there is absolutely no need to specifically restart your computer. It is enough to execute in command line this command: cat /proc/cpuinfo In response, you will receive a list of parameters of your computer’s processor, including the clock frequency.

Operating room users Windows systems can get information about the processor frequency using a small utility called CPU-Z. You can view it and download it on the following page:
http://www.cpuid.com/softwares/cpu-z.html

Some computers (mostly laptops) are capable of dynamically changing the clock speed depending on the load. By periodically running the cat /proc/cpuinfo command on Linux or running the CPU-Z program on Windows, you can monitor its changes in real time. Please note that on computers that have dynamic clock control, the processor running at zero speed is not a sign of clock fraud. by its manufacturer.

To fully optimize the operation of your computer, it is recommended to change the operating parameters of the central processor and RAM. Naturally, before starting this process, it is better to check the stability of these devices.

You will need

• - CPU-Z;
• - Speed ​​Fan.

Instructions

Install the CPU-Z program and run it. Find out the current processor performance. The overall CPU operating frequency is obtained by multiplying the multiplier by the bus frequency. To provide maximum effect from overclocking the processor, it is necessary to increase the bus frequency.

Repeat cycles of PC acceleration and checking the stability of the central processor and RAM until the system detects errors. Monitor CPU temperatures regularly using CPU-Z or utility utilities such as Speed ​​Fan.

Any modern discrete video card has its own frequency. Has the same frequency as a processor graphics adapter, and so is his memory. The higher these indicators, the more powerful your video card. Also, when overclocking a board, you need to rely on the factory settings for the frequency of the memory and processor of the card and, based on this, overclock it.

You will need

• - computer;
• - BY Catalyst control center;
• - RivaTuner program.

Instructions

If you are the owner video cards from ATI, then it is likely that no additional programs you won't need it. Catalyst is included in the driver kit for these video cards. control center. If you do not have it installed yet, install it from the driver disk. You can also download this software from the company's website. You need to download one of the latest versions of the program.

Launch Catalyst control center. If you are launching the program for the first time, check the “Advanced” option and proceed further. Then, in the main menu of the program, click on the top arrow, and in the menu that appears after that, select ATI Overdrive. A window will appear in which there will be two bars, to the right of which there will be numbers. The indicator on the right near the top bar is the processor frequency video cards.

Select the icon that says "Diagnostic Report." A window will appear that will be divided into two parts. At the bottom of the window, drag the slider to the very bottom. Now find the line “Core Frequency”. The indicator that will correspond to this line is the processor frequency. Below is the line “Memory frequency”. Accordingly, the indicator in this line is the memory frequency at which your video card operates. If necessary, by clicking on the floppy disk located below, you can save the report in text document.

When choosing a computer and its components, people usually pay attention to the following characteristics: the power of the video card, the amount of RAM and hard drive, as well as frequency processor. The latter value is one of the main indicators on which the operation of the entire computer depends.

The central processing unit (central processing unit or CPU) is an electronic unit or chip that executes machine instructions (program codes) and is the main part hardware computer or programmable logic controller. Sometimes it is also called a processor or microprocessor. One of its main characteristics is clock frequency. The speed of operation, as well as the “Response” time of the device, depends on it. Accordingly, the higher the frequency value (from 900 to 3800 MHz), the faster the entire computer will operate. Clock frequency represents the number of clock cycles (operations) a processor can perform per second. It is proportional to the bus frequency value. As a rule, from the clock frequency processor its performance directly depends. But this statement is only relevant for models of the same line, since performance processor other parameters also have an impact, for example, the size of the second level cache, frequency and the presence of a cache, special instructions, and so on. Clock frequency can also be defined as the frequency of the clock pulses of an electronic synchronous circuit. which arrive at the system input from the outside in one second. This parameter characterizes the performance of the subsystem, that is, the total number of operations performed per second. Of course, a lot depends on this value, since it directly affects the performance of the computer. But you need to understand that different processors have their own capabilities, advantages and disadvantages at the same core frequency. In addition, interface blocks processor work with the clock frequency of the motherboard, and this value can be much less than the frequency of the system itself processor. Also, the declared frequency value does not always truly reflect the real picture, because It happens that manufacturers indicate more high frequency, which refers to a similar processor from another company.

At times, a user may need to know what kind of processor is installed in his computer and what characteristics it has - for example, when installing a game or when purchasing new hardware. And in some cases, manual control of the processor properties may be necessary. Let's look at how to do this.

How to find out the properties of the processor in Windows

The good news is that you don't need any third-party software to find out what kind of processor is installed in your system. If you only want to know him basic parameters- for example, clock speed or number of cores - built-in ones are sufficient Windows tools, namely, Control Panel and Device Manager.

As a rule, the “Control Panel” item is located directly in the “Start” menu. Click on this item and go to the control panel.

We enter the “Control Panel” through the “Start” menu

We need the “System” item. This menu contains information about both the processor and RAM, as well as the properties of Windows itself installed on the device.

In the control panel, look for the “System” item, select it

In the window that appears, find the line “Processor”. There is information about which processor is installed in the computer: the manufacturer, the name of the processor and its clock frequency in mega- or gigahertz. For example, in the picture above, the computer is running with an Intel processor with a clock frequency of 2.5 GHz.

In the “System” window of the control panel there is a line “Processor”, which displays information about the processor

Now let's check the number of cores. In already open tab“System” on the side there are buttons to go to different system menus. Find the “Device Manager” item among them and click on it.

The System window has buttons that open various system menus; we need the "Device Manager" item

In the “Device Manager” that opens - a menu that displays information about all physical elements installed in the system and their drivers - we need the “Processors” item. The dispatcher marks each processor core as separate device, so it will be easy to understand. Expand the “Processors” tab and see several identical devices; their number is the number of cores in your processor. As you can see, the picture shows a quad-core processor.

In the "Device Manager" there is a "Processors" tab; opening it, we see how many cores are in the processor on our computer

If you want to check the processor drivers, you can do it directly from here by right-clicking on the processor and selecting “Properties”. In the menu that appears, there is a “Driver” tab, where you can view information about installed driver or even try to update or rollback it. However, as a rule, manual updates No processor drivers are needed: this is done automatically.

If for some reason you need information about the processor driver, this can be done through the processor properties menu in the device manager

Temperature measurement

If your computer regularly overheats or is simply overloaded, it makes sense to monitor the processor temperature: it may be necessary to update the cooling. Check the processor temperature using regular funds Windows is not possible: you need to either check the temperature through the BIOS, or use third party programs to control computer hardware. We will cover both methods. By the way, with their help you can also find out other processor data.

How to measure temperature using BIOS

BIOS - or more precisely BIOS Setup, the most widely used part basic system I/O is the easiest way to check what the temperature of your processor is. The BIOS Setup menu displays a number of properties of the “stuffing” of the computer, and the only thing we can do is go into the utility and find the line responsible for the temperature of the program. The main disadvantage of this method is that the check will be carried out before entering Windows, when the processor is not yet “loaded” with working with operating system and all its applications. Therefore, the result may differ less than what you get by measuring the temperature under Windows using special programs.

The first step is to enter the BIOS. This is done like this: when bootstrap computer, even before the system logo appears, a window with information about the motherboard appears for some time (for some configurations, just a dark window with a blinking cursor). When this window appears, you need to press a key combination to enter the BIOS (most often it is Del or F2, but the combinations vary depending on the manufacturer, and there are a lot of them; usually you can find out “your” combination from the information on the screen).

The BIOS Setup program will open. The line we need is called CPU Temperature and is located in different places depending on BIOS version. Typically, the section in which this information is located is called:

• PC Health Status(Status);
• Hardware Monitor (H/W Monitor, Monitor);
• Power;

If you don’t want to go into the BIOS or are interested in the processor temperature under load, you can use it instead special utilities, working with temperature sensors on the CPU under Windows.

How to find out the processor temperature through programs

There are several programs for monitoring the physical parameters of the computer, such as fan speed, voltage consumption and temperature on the “internals” of the computer. You should look for a utility that can read readings from a temperature sensor among these programs.

AIDA64

AIDA64 is a powerful program for tracking components of both hardware and the system itself. Its functions include far more than just checking the CPU temperature, and it is extremely useful for anyone who is at least a little interested in the condition of their PC. Of all the possible program options, it is one of the most popular, so we will start with it.

After installation, simply launch the program and go to the “Sensors” tab. The utility itself will display information about the temperature on all processor cores individually, as well as on other components of the computer “stuffing”.

The "Sensors" tab of the AIDA64 program shows the temperature on the processor and other components computer

The main disadvantage of AIDA64 is that this program is paid. However, free version You can get it for 30 days, and this is definitely enough to check the processor temperature.

CPUID HWMonitor

This program is not as informative as the previous one, and is intended only for viewing information about the hardware. But it is free, popular and quite simple, so you won’t have to figure it out for a long time either. After installation, open and find the name of your processor in the list of devices (we discussed in detail how to find it out in one of the previous paragraphs).

In the same way, we see the temperature of each core displayed on the screen in Celsius and Fahrenheit, and also observe its maximum and minimum values.

In the CPUID HWMonitor program, the processor temperature can be viewed in the tab with its name

The HWMonitor website allows you to download the program for free, and also, for a reasonable fee, purchase a Pro version with additional functions.

HWInfo

Another one free utility, which differs from the previous one in extremely high information content and a large number of functions: up to tracking all processor activity in real time with plotting. The program is distributed under a freeware license, so you don’t have to pay anything for it. And looking at the CPU temperature in it is generally as easy as shelling pears: just go to the main menu of the program and select the Sensors item.

The window that opens will display information from the component sensors. This can be not only temperature, but also energy consumption or operating speed; any indicator is displayed in four columns: current, maximum, minimum and average values. The processor in the long list of devices is represented by the CPU item. That's what we need.

HWInfo provides the user with many functions, one of which is viewing sensor readings - located in the Sensors menu

HWInfo can be downloaded for free from the official website.

Piriform Speccy

A utility from the creators of the well-known CCleaner, designed to view the status of PC components. It features a proprietary, pleasant interface and full support for the Russian language: if you have problems with English, Speccy will be the optimal solution. There are free and paid versions: the paid version has advanced functionality and auto-updates, but for our purposes the free version is sufficient.

After installation, you just need to go into the program: the processor temperature will be displayed among other data on the main page. If you want to know the characteristics of the processor in more detail, you should select the “Central Processing Unit” item in the side menu.

Speccy program provides the necessary data directly in the main window and in Russian

You can download Speccy from the program developers website.

CPU Power Management in Windows 7

Windows 7 provides a wider range of power management tools than its predecessors. This is both the choice of a power supply scheme from those already available, and customization food for yourself, as well as additional features, including hidden ones. Basic Features will be useful to everyone: from those who strive to maximum performance in games, to those who save electricity - but fine tuning is recommended only for experienced users.

Power settings can be found in the “Control Panel” (how to access it is described in detail above). They are usually called “Power Management” or simply “Power Options,” so, in general, you don’t need to go to the control panel: you can just type the word “power” in the search bar, and the system itself will provide a link to the settings.

In the window that opens, you can immediately select the power scheme for your computer. One of three: balanced, energy-saving (recommended for laptop users running offline) and high-performance (for working with “heavy” programs, including games). In addition, from here you can create your own power supply scheme or configure existing ones.

This is what the main power menu window looks like in Windows 7. You can customize an existing power plan or create your own

Creating a new nutrition plan is based on three main schemes: in fact, any custom plan is just one of the main ones with some additional settings.

When creating a power plan, you can choose which of the main ones it will be based on

In the circuit settings, you can change the time after which the system will go into sleep mode and the time after which the screen will go dark, and for laptops you can configure different behavior when operating on mains power and on battery power. Including the item “Change” additional settings", providing access to more advanced power options.

This is what setting up a power plan for laptops looks like (in stationary PCs there is no separation between network and battery). From here you can go to advanced settings

Advanced settings allow you to fine-tune power consumption. From settings of wake timers to direct control of processor power: maximum and minimum performance percentages, as well as cooling control. It is not recommended to change these settings unless you are sure of what you are doing! Otherwise, there is a possibility of simply ruining the processor.

Enabling hidden computer functions from the registry

For even more fine-tuning, you can go into the registry and edit some keys to open access to blocked for regular user options. To edit a key in the registry, just import the rows from the table below into it. Let's figure out how to do this.

First you need to create a reg file. For this:

1. We create in any place convenient for you text file Notepad.
2. In the file we write in the first line Windows offer Registry Editor Version 5.00 - it is very important that it be exactly like this, without errors.
3. Leave the next line empty.
4. In the third line we write one of the codes indicated in the table: completely, do not change anything.
5. We write the following codes in any order. Each time we write new code, we skip one line. There should always be one blank line between commands.
6. When all the necessary codes have been entered, save the file under any name in the .reg format. That's it, the registry file is ready, and now all that remains is to import the changes into the registry itself.

When the reg file is created, type in Windows search the word regedit.

In the registry editor that opens, click “File - Import”.

We indicate the path to our reg file and select it. If you did everything correctly, the registry settings should change.

Table: registry keys for accessing hidden power settings and their meanings

What needs to be changed (imported into the registry)	Result
"Attributes"=dword:00000001	the so-called core parking is enabled, which allows you to disable unused processor cores in order to save energy
"Attributes"=dword:00000000	enables a setting that determines the maximum number of cores in idle state
"Attributes"=dword:00000000	opens the option "CPU performance kernel suspension kernel override"
"Attributes"=dword:00000000	opens an option that allows you to manage processor idle time
"Attributes"=dword:00000000	An option appears that allows you to control power reduction

After applying these settings Extra options The processor power supply will look something like this:

This is what advanced processor power settings look like in Windows 7, if enabled in the registry hidden functions

Now that hidden features are enabled, you can control and fine-tune even complex parameters power management.

Knowing where to look at your processor data, how to determine its temperature and even change power management is very useful for an experienced PC owner who decides to optimize the CPU using software methods. But this information may also be useful for the average user: everyone may sometimes need to check the operation of the cooling, find out the processor frequency, or reduce energy consumption.
