Increase virtual memory in XP. How to configure the paging file? What is a virtual memory

Hello dear readers! Today we open the cycle of articles about computer optimization on Windows. Let's start with such a thing as. In this article you will find answers to such questions: where is the paging file?; How to configure the paging file?; How to set the optimal size of the paging file for different volumes random access memory.. Go!

File Podchock (page File.sys.) - this is system file. On the hard disk (as a rule on a system disk) of a computer that serves as if a supplement (extension) to RAM. Also this additional memory is called computer virtual memory.
Virtual memory - Computer memory management method for performing programs requiring large amounts of RAM than it is real on the computer. The missing operational memory such programs are obtained from the paging file. In other words, the paging file unloads the RAM during periods of its strong loading.
RAM at times faster than memory paging file. If you simultaneously start multiple applications in the system that consume a lot of RAM, the data of unused from them will be unloaded from RAM into less quick virtual memory. The active applications will be serviced directly with the RAM (RAM). Also, if such as the rolled application, deploy, then the data from the virtual memory will reiterate in the RAM.

How to configure the paging file and change its size?

Competent proper setting Paddock file will help to significantly speed up the operation of the computer.. This sin would not take advantage. Where can I configure it?

1. For Windows XP.:
   Start\u003e Settings\u003e Control Panel\u003e System\u003e Optional\u003e Speed\u003e Options\u003e Advanced\u003e Edit
2. For Windows 7/8 / Vista:
   Start\u003e Setup\u003e Control Panel\u003e System\u003e Extra options Systems\u003e Speed\u003e Settings\u003e Advanced\u003e Virtual Memory\u003e Edit

To paragraph Speed You can also enter the SysDM.CPL command on the command prompt Perform (command line You can open by pressing Win + R).

If you are all done correctly, you should be in the window Virtual memory. By default, in Windows 7/8 / 8.1 / 10, the voltage file is determined automatically by the system itself.
As can be seen in the picture, the paging file can be configured for each partition (and each disk) separately. To set your sizes of the paging file, you need:

1. At the very top of the window, take a tick from the point Automatically choose the volume of the paging file.
2. Select the section (or physical disk) for which the paging file is configured.
3. Put the switch to the point specify the size, specify Source size and Maximum size (indicated in megabytes)
4. Be sure to click on the button Set.

To disable the paging file, place the switch to the item. Without a paging file.

Windows paging file size. What is the right one?

At the expense of the optimal size of the paging file is different versions. I will express my point of view on this account, which is based on my observations and experiments with a paging file on various equipment. It may coincide with the opinions of some IT specialists. I am a supporter version that if 6-8 GB and more RAM installed on the computer, then podchock file can be turned off at all. I think that large volumes of the paging file, only slows down the computer. Of course, if the volume of RAM is less than 6 GB, then it is better to define a certain amount of additional virtual memory.
How to set the volume of the paging file? The minimum size of the paging file must coincide with the maximum. For example: 512-512, 1024-1024, 2048-2048 is the correct filling, and 512-1024, 1024-2048 - incorrect filling.
The same indicators of the minimum and maximum size of the paging file, reduce this file, and this consequently speeds up the process of reading information from it.
Now, depending on the volume of the RAM, let's see what size of the paging file must be set. There are the following approximate indicators:

• the optimal size of the paging file for 512 MB of RAM is 5012 MB;
• the optimal size of the paging file for 1024 MB of RAM is 4012 MB;
• optimal swap file size for 2048 MB RAM - 3548 MB;
• the optimal size of the paging file for 4096 MB of RAM is 3024 MB;
• the optimal size of the paging file for 8 GB of RAM, - 2016 MB;
• the optimal size of the paging file for 16 GB of RAM (and more), - without a paging file.

Of course, this subjective look and these indicators cannot be absolutely accurate, recommended, but in practice it is they who gave effect. You can experiment yourself and find the best combination for your computer. There are some notes here.

For example:

1. Some applications require a paging file. It may result in errors in such applications. When the virtual memory is disconnected on the system disk, it will also be an impossible memory dump record with BSOD "AH (blue screen of death).
2. If you, as a rule, turn out several applications, leaving them running, and switch to others themselves, then you can also need a large volume of the paging file, since these rolled applications are recorded in it. Although, and here it all depends on the volume RAM.

The correct location of the paging file. What disk include?

If you have several physical disks on your computer, then install the paging file is needed on the most fast disk. It is believed that the paging file sharing into 2 parts:

1. The first part on the system disk (section) (just to record the debug record information blue screens of death)
2. Second part on the fastest disk

At the same time, the system during operation refers to the least loaded section, not a touch first.
It is also recommended to create a file under the file separate section, with a memory volume equal to either close to the size of the paging file (for example 20,24mb). This trick allows you to get rid of the fragmentation of this file.

Results:

I hope the tips presented in the article will help you correctly configure the paging file on your computer and optimizes its work. If you have questions, write in the comments, I will try to give comprehensive answers on them.

During the maintenance of computers and laptops, the problem often arises with insufficient device performance when performing some programs. The main feature of this catch is the message of the system that the task failed due to the shortage of free space for virtual memory. This applies to a greater degree of elderly computers that have a small amount of RAM. Although some modern cars Also faced with such a problem. This happens when the user sets a large number of Tasks device. At some point, when the memory resource is exhausted, it will pop up this sinister message.

This was the reason for creating this material that tells you how to increase virtual memory. First, let's see what it is. It is a combination of RAM, which is installed in the system, with a paging file.

It follows that there are several ways to solve the problem. How to increase virtual memory? The first option is quite banal. Buy an additional RAM chip and install it in the systemist. I think there are no explanations here. This topic is written enough material.

To increase the virtual memory, you must enlarge for this go to the "Start" menu, go from there to the "Control Panel". When it opens, select the "System" section, then "Properties". Here you already open the tab "Passing and".

Next, in the "Speed" section, go to the "Parameters" subsection. Locate the link to the virtual memory and select "Change". In these settings, specify the partition of your hard drive on which it will be stored, then specify the desired swap size. Make it one and a half times the most common amount of your RAM. It will be ideal for its placement on which the operating system is not installed. It will also improve the performance of your car.

When all the parameters are entered, confirm them with the "OK" button and restart the computer. Now you know several ways to enlarge the virtual memory of your computer.

Sometimes when using applications that are demanding on computer resources, the operating system issues a message that too little virtual memory remains. What represents virtual memory Computer, what role does it play and how can it be increased?

What is a virtual memory?

Virtual memory is a temporary storage of hard disk data that is used. operating system In the case when RAM becomes not enough to perform a task. Thus, the virtual memory or, as it is also called, the paging file is something like additional RAM, it is only located on a computer hard drive.

If a small amount of RAM is installed on your computer, then performance gains in programs can be achieved if you increase the size of the paging file. However, note that reading from the RAM module occurs significantly faster than from a hard disk, so if you can add the amount of RAM, it is preferable to do it. But when there is no such possibility, the virtual memory can be very much by the way.

How to increase virtual memory?

The volume of the virtual memory of the computer is adjusted in the speed parameters. To get to them, go to the menu Start, Go to Control Panelthen in the section System and select Additional system parameters.

In the window Properties of the system Click the tab Additionally and click on the button Parameters In chapter Speed.

In the window Performance parameters Go to the tab Additionally and click on the button Change in the subtitle Virtual memory.

Here you will need to check the checkbox at the point Specify size And ask numerical values For the original and maximum sizes of the paging file. Then press the button Set. The changes will take effect only after you restart the computer.

As for the size of the paging file, it is impossible to advise the installation of any particular value, since the amount of virtual memory should be set in proportional dependence on the amount of RAM. It is advised to set the initial size of the paging file by one and a half times more than the amount of RAM, and the maximum is three times greater than the original. However, while the paging file will gradually fragmented, which will affect the speed of its work. Therefore, if the amount of RAM installed with you exceeds at least 3 GB, it is better to set the same size for the original and maximum swap file values \u200b\u200b- in one and a half or two volumes of RAM.

And it became clear that there is no memory much. Sometimes there are such moments when it's right now you need more RAM (running for example or virtual Machine Enable), and the store is lazy to run. Yes, and components are not selected simply without careful analysis. Here for such critical days and created virtual memory or file paging. In this article, I will tell you what it is and a computer.

The virtual memory is called the operational memory of the system + paging file. Or simply file Podchock. The latter is located on the selected section of the drive (hard disk) and is called page File.sys.. This file It is hidden, so you can immediately not see it.

Virtual memory was developed for programmers as the simplest method Increase RAM.

The first systems using virtual memory appeared in the 70s. In the 80s, the technology gained wider distribution and in the 90s began to be used in personal computers. For us with you this technology is nothing more than simple magnification Computer RAM.

Modern operating systems allow you to manage the computer's virtual memory. Consider this process using the example of Windows XP

Increase virtual memory in Windows XP

To do this, go to the menu Start choose My computer And by pressing the right mouse button, call the context menu.

Or call the context menu on the icon My computer On the desktop.

select item in the menu Properties

Go to the tab Additionally, We are looking for a field Virtual memory and press the button Change

In the next window you see the field Disk With the listing of all sections of your drives. Select the section on which we want to locate the paging file and go to the field The size of the paging file for the selected disk.

Microsoft recommends choosing the original size (MB): equal to 1.5 x (RAM volume - RAM). In the Total Switch File field on all discs, you see this figure in the line it is recommended. In our case, the amount of RAM is 1 GB \u003d 1024 MB, therefore the system recommends 1534 MB.

Maximum size Paddock file is recommended to choose twice as much source. If not enough can always be increased.

You should pay attention to the line Free: 771 MB in field . This is the amount of free space on the selected section of your drive. It is extremely important that after setting the size of the paging file on the disk, the free space remains. This is especially true for the system disk. From a free place on the section, take the maximum volume of the paging file and see a real free space. For the system disk I recommend leaving at least 1 GB if it turns out less, select another section for example D or E.

So in the field Switch file size for selected diskthere is a choice of 3 options: a special size, size of system selection and without paging file. If you want that the operating system itself assign the size of the paging file to select the appropriate option.

How to install operational windows system XP can be read in the article how to install windows

Increase the paging file in Windows 7

The principle is the same. Go to the menu Start Find A computer And call the context menu. Select item Properties

In the opened window on the left choose Additional system parameters. This window can also be discarded Start\u003e Control Panel\u003e System and Security\u003e System

In the window we turn out to be on the tab Additionally We are looking for a field Speed and press the button Parameters…

In the appeared window, go to the tab Additionally Find a field Virtual memory and press the button Change ...

In this window, you can put "bird" in the string Automatically select the swap file And the operating system itself will select the section on your drive and assign the recommended size of the paging file.

The remaining functions are the same as in Windows XP. We need to choose the section of our drive in the field Switch file size for each disk. Next, you need to either specify the size of the paging file manually, or allow the operating system to select the desired size itself or disable the paging file on this section.

With a free space on the system disk, the same situation, it is necessary that it was guaranteed. From free disk space, take away maximum size Paddock file and it is desirable that even 2 GB remains. If you better create a paging file on another section.

Select the corresponding point, enter if the sizes of the paging file and press the button Set.

Switch file created.

You should pay attention to the following. The operating system resets what is not placed in RAM into the paging file. The latter is located on your computer's hard disk and this HDD hard drive. For SSD need not. HDD - a slower device than RAM. Therefore, even using the paging file, your system will slow down + hDD It will work more intensively. Hence, this technology It is recommended to use briefly, in order to save the hard drive and your nerves. In other cases, it is recommended to simply increase the amount of RAM.

Output

Today we have dealt with the question how to increase virtual memorycomputer. Find out that this is the RAM (RAM) + paging file on the hard disk. Found out how to manage virtual memory in Windows XP and Windows 7.

"+" - virtual memory

• the user has a much greater amount of memory than physically provides RAM.

"-" - virtual memory

• slow operation of the system
• more intensive use of a hard disk and as a result, a decrease in its resource.

If you want to supplement something or have more accurate information about the sizes of the paging file or simply, a question arose, be sure to write a comment.

Virtual Memory - Computer Management Method, which provides the ability to run programs that require a greater amount of RAM than installed on a PC. This is done by unloading unused data into a disk file. It is called pagefile.sys. This method of expanding computer hardware features appeared before Windows XP and is constantly being improved from version to version.

PageFile.sys file is a paging file (swap file). The computer's virtual memory is expanding according to the following algorithm. Windows XP, when starting an abundant number of programs or the operation of the resource-intensive application, unloads the data inactive on this moment Applications and some background services in RAM and records them in the Page File.sys file. It is mainly located on the system section. But with the Vista output, it was possible to use a USB flash drive to store the paging file on it.

Virtual memory thus slows down the operation of the system (speed of access to cells hard disk significantly less access speeds to RAM cellular cells), but allows you to work with Windows applications that require more RAM than physically installed on the computer.

With a lack of RAM better decision There will be another bar than to expand it at the expense of the paging file, but there is no such possibility, because we consider how to install and change the size of the swap file.

And one more important moment: Windows XP supports memory, a slightly more than 3 GB of RAM due to the insufficient number of targeted space. When installing 4 GB, the operating system will be able to work with ~ 3.25 GB of RAM, the remaining volume will be inactive.

Swap file configuration

Setting the paging file in windows Environment XP is carried out similar to new versions by the method.

• Call the context menu of the My Computer folder and launch the Properties dialog.

• Go to the last tab in the first row called "Advanced", where you can expand the computer's memory.

• In the Frame "Speed" click on the "Parameters" button.

• Go to the second tab with the name "Advanced".

• In the "Virtual Memory" frame, click "Change".

After that, configure the paging file in XP.

• Move the trigger switch to position: "SPECIAL SIZE".
• Choose system Disk Tagged "C:" and enter the volume of the paging file.

Many experts recommend setting its minimum and maximum volumes equal. In this way additional memory It is not fragmented, increasing this speed and slightly reducing the wear of the hard disk.

As for specific figures, here opinions are diverged. Optimal setting The paging file in Windows XP is carried out by the operating system, because newcomers are recommended to install it "size by selecting system". In the future, the experience will tell you how virtual memory requires your computer for normal operation, but the paging file should not be less than the volume of RAM.

• After selecting the option (and the limitations of the volume with a specimen amount), be sure to click "Set".
• Click "OK".
• Again, click on the "OK" button by reading the message with the alert that the virtual memory will expand after rebooting the computer.

• On offer to restart PCs responding on the basis of the situation.

It is not necessary to restart the computer immediately after the adjustment of the paging file has been completed.

It is worth noting that when using two or more hard disks (It is HDD, not partitions) in the system paging file is better to be placed on the hard drive, different from which the system disk with installed windows XP. Moreover, the Page File.sys file should be placed on the first partition of this disk, since access to it is performed faster in view of the smaller diameter of the plate. This is a little unloading system section And increase the speed of the PC.

If you use a dynamic paging file, it follows from time to time to defragment by means of a special defragmant (integrated in Windows XP utility for these purposes is not intended). For these purposes, the tiny program is PageDefrag.
