What does virtual memory mean My computer is 256MB memory, and the initial and maximum values are se

The Windows operating system uses virtual memory to dynamically manage runtime swap files. In order to provide more memory capacity than the actual physical memory for use, the Windows operating system takes up a portion of the space on the hard disk as virtual memory. When the CPU asks for it, it reads the data in memory first.

When the memory capacity is insufficient, Windows writes the data that needs to be stored temporarily to the hard disk. So, the size of the computer's memory is equal to the actual physical memory capacity plus the size of the "paging file" (i.e., the swap file). If needed, Paging Files uses all available space on your hard disk.

According to Microsoft's recommendation, the page file (virtual memory) should be set to a multiple of the physical memory, and it is recommended to set the maximum and minimum values to the same, if it is 512M memory, set the virtual memory to half of the total memory.

The memory of your favorite phone is 256M, that is, the maximum and minimum values can be set to 256*, which is enough.

How to set up: Here we take Windows XP as an example to introduce the setting method of virtual memory, right-click "My Computer", select "Properties" "Advanced" "Performance Settings" "Advanced" "Change" to enter the "Virtual Memory" setting interface. Select the system drive letter in the drive list (C drive is the default system disk), select "No paging files", and then click "Settings" to cancel saving page files on the system disk; Then select other partitions, select "System Management Size" or "Custom Size" according to personal needs, set the appropriate values in "Initial Size" and "Maximum", click "Settings", and then click "OK" to complete the setting of virtual memory.

Setup scheme: In general, it is recommended to select "System Management Size" to let Windows automatically allocate and manage virtual memory, which can dynamically adjust the size of virtual memory according to the actual memory usage. If the hard disk space is tight, when setting the page file, you only need to ensure that it is not less than 3 4 of the physical memory.

If the physical memory is large, the role of the virtual memory will no longer be obvious, and we can consider disabling it (more on this later).

1.Initial Size.

Windows recommends that the minimum value of the page file should be the current system physical memory capacity plus 12MB. For users with a physical memory capacity of less than 256MB, it is recommended to set the minimum value of the page file to a larger value: for users with a memory capacity of less than 128MB, it is recommended to set the multiple of the current physical memory capacity to the minimum value of the page file; If the memory capacity is between 128 and 256 MB, it is recommended to set the multiple of the current physical memory capacity to the minimum value of the page file.

2.Settings for Maximum.

In general, the larger the maximum value of the page file, the better, and it is recommended to set it to 2 to 3 times the minimum value.

Virtual memory is the use of hard disk space as memory to make up for the lack of RAM space in the computer. When the actual RAM is full (in fact, before the RAM is full), the virtual memory is created on the hard disk. When the physical memory is used up, the virtual memory manager selects the low-priority portion of the memory that has not been used recently and writes it to the swap file.

This process is hidden from the application, which treats the virtual memory as the same as the actual memory.

The setting of virtual memory is a general description of the online technical documents, and I personally think that it can be set according to the actual situation of commonly used software. Recommended for experienced users.

Nowadays, there are many tools (such as Windows Optimizer, Super Rabbit) that can change these settings very well, and the tools will also make corresponding recommended settings according to the actual situation of your computer.

Your physical memory is about 2 times the same as the maximum.

Take advantage of the hard drive to automatically scratch files for increased speed. It is best not to set it in the system disk, and generally use the recommended value.

Virtual memory can not replace the use of physical memory, the setting is too large and will only drag down the system and will occupy the corresponding hard disk space, 8G memory is completely enough for ordinary users, not enough to add physical memory instead of changing virtual memory.

1g=1024M, the minimum value is 8000MB, and the maximum value is 16000MB. However, if it is larger than 4G memory, the virtual memory system can be automatically allocated, and the performance improvement is not so obvious if the setting is large.

1g=1024m。

The minimum value is 8000MB and the maximum value is 16000MB.

However, if it is larger than 4G memory, the virtual memory system can automatically allocate it.

Larger settings don't have as much of a performance boost.

1. The so-called virtual memory is to use a part of the hard disk space as memory when your physical memory is not enough.

2. Custom virtual memory, 736 (768) physical memory, the initial value can be set to 512MB, the maximum value can be set to 1024MB, if it is found that it is not enough in use, it can be set to a larger size.

3. It is best to set the virtual memory in the partition with a large remaining disk space in other partitions, such as d and f, so as to avoid the system from performing frequent read and write operations in this partition and affecting the system speed. In a computer, one is sufficient, and there is no need to set up virtual memory in other partitions.

4. The method of setting virtual memory is: right-click on my computer - Properties - Advanced - Performance Settings - Advanced - Virtual Memory Change - Click on C drive - select "No paging file (N)" - Settings", then the virtual memory in C disk will disappear; Then select the D drive, select "Custom Size" - enter the value in the "Initial Size" and "Maximum" text boxes below - "Set" - OK - Restart, and the setting is completed.
