Advice 1: How to know the architecture of your CPU

Architecture is one of the defining characteristics of the processor. This is especially true of installing the operating systems, when you need to choose which version to install. The architecture depends on the computational ability of the processor and its ability to work at different frequencies.
How to know the architecture of your CPU
Under processor architecture refers to the family and generation of processors, which have its own set of commands. The choice of a suitable distribution of the operating system in accordance with the characteristics of the processor allows to achieve maximum productivity in work with computer.
The architecture of processors of Intel, as a rule, is designated as x86 and refers to the stones of the collections, i286, i386, i486, etc. Processors from other companies (AMD, Apple, VIA was compatible with Intel and had a similar classification. Then began to give them names that had gradually become an independent trademark. It complicated their classification.
Look at the model of your CPU in the technical documentation. If its value matches the Pentium (except for the Pentium 4 Extreme Edition, Celeron, Celeron D, Xeon, AMD K5, K6, Duron, Athlon, Sempron, a processor has the x86 architecture. If the processor is marked as Opteron, Athlon 64, Athlon XII, Sempron 64, Turion 64, Pentium D, Xeon MP, Atom 230, Atom 330, Core 2 Duo and a MacBook, it has the architecture x86_64.
Knowledge of architecture is required in distributions are open source. Otherwise, a wrong selection, the system will not install or will not function correctly.
To determine the architecture you can use special software programs for Windows, such as Everest or CPU-Z. They will show support for AMD64 or EMT64.
The x64 architecture is more advanced than x32 (x84). All modern multi-core systems are 64-bit. They are backward-compatible, i.e. able to work with 32-bit applications.

Often, manufacturers mark the product as i386 or i586, which implies 32-bit system (x86).
Useful advice
Processors Macintosh G3–G5 and PowerBook have the ppc architecture.

Advice 2 : How to find 32-bit or 64-bit kernel mode

For Windows XP there is only 2 ways how to know 32 or 64 version installed on the computer.

The first method is that you need to open the system window in control panel:

- Go to "start", choose the Run command.

- Enter in the line "Sysdm.cpl" and press "OK".

- Go to the tab "General". Information about the operating system (OS) will be displayed as follows:

Is a 32-bit version of the OS will be presented: версия_Windows Hrod will be displayed under "System".

-A 64-bit version of the OS are presented: версия_Windows XP_ х64_год will be displayed under "System".

The second method is to view the system information:

- Go to "start", choose the Run command.

- Enter in the line "winmsd.exe" and clicks "OK".

- Go to "System Information" select the tab "CPU".

The data about OS are displayed in the following way:

If the value of the processor starts with the prefix "X86", this record means that your computer has a 32-bit version of the OS.

If the value of the processor starts with the prefix "AMD64/IA64", this means that your computer is running a 64-bit version of the OS.

If using the above methods you cannot know the number of bits of your OS, then you should go to section "next steps".

To find out whether the version of Windows you can refer to the documentation that came with the computer, or learn it from a manufacturer of computer equipment.

Computers with the Intel Itanium processor, are controlled by a 64-bit version. To date, the 64-bit version work on the computer on which you installed the AMD64 and Itanium.


Advice 3 : How to know what bit processor

Suppose you have a computer, but not to him absolutely no documentation. Accordingly, to know the exact parameters of the contents of the stuffing of the system unit is not possible. And you for whatever reason need to know the bit width of the processor of the computer.
The main characteristics of the processor
You will need
  • The program CPU-Z
There are many ways to check it. The easiest option does not involve the installation of any additional programs, but at the same time it is not accurate enough. For implementation, just run the task Manager, simultaneously hold down the three keys Ctrl+Alt+Delete in Windows operating system. In the opened window in the Performance tab, in the line "history CPU" available in Windows is the number of cores of the processor of your computer. If there are two or more, you can 99% be sure that the bitness of the processor of this computer is 64 bits as all modern dual core processors - 64-bit.
But the system unit can be quite old and not been updated for a long time, thus a way to find out the bitness of the processor is not suitable. To access additional programs. For more accurate results you'll need at least a couple of these software utilities. The first and simple enough to master - CPU-z Download it from the official website of the program - this little utility is absolutely free and takes very little space on the space of your hard drive. Install it, run it, and in the very first tab called "CPU" displays all the information about your processor. Find the line "Instructions". In it you can see, for example, here such code: MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, ЕМ64ТВКонкретно in your case you are only interested in the acronym "EM64T" - it means that the bit width of the processor - 64-bit. The same means, and "x86-64". Everything else - the processor 32-bit wide.
Another useful program is AIDA64. In contrast to CPU-Z it is paid but has a 30-day trial period. Downloading from the official website by installing and running, go to the tab "mainboard" and then in the item of "CPUID". The line "instruction Sets" will tell you the bitness of the processor is 64 or 32 bits.

Advice 4 : How to know the processor model

If you bought a used computer, no harm will check the configuration of it devices. In particular, to identify components that are installed in the system unit. To determine the model of the processor, you can use the following methods.
How to know the processor model
The first method is most simple, not requiring installation of any additional programs. To learn the model of the processor, first on the desktop click on "My computer" or corresponding item in menu "start". Then click the right mouse button and select "Properties".
The appearance of the window depends on the version of the Windows operating system installed on your computer. In any case, in one of the rows you will find information about the model of the processor. Often, however, except the name of the device model, you might want to know its technical characteristics or temperature sensor. For these purposes, you need to install the program, it may or Everest, or SISoftware Sandra. To find the installer any of these utilities, use an Internet search engine.
Consider the search for relevant information using the program Everest. Running it, you will see a window similar to Windows Explorer, the only difference is that instead of icons of the folders specified device. In the left part of the window you will find a list of devices grouped by some characteristic. To start menu, expand "motherboard".
In the opened list, click "CPU". As a result, in the right part of the window you will find not only model the processor, but also technical information.
If you need to check the temperature of your CPU, then open the option "Computer", located on the right panel, then click on the item "Sensor". You will see information about the temperature of the main devices of your computer. Remember that the temperature of CPU in laptop one and a half times higher than the temperature of the processorthat is installed in a stationary computer.
