虚拟内存设置多大才比较好(虚拟内存大小设置多少合适最专业)

1.5 times the physical memory. Virtual memory is generally set to 1.5 times the physical memory. Take an 8G memory stick as an example: If the system is 32-bit, it only supports 3.2G, and the virtual memory should be set to 4800. Virtual memory is a technology for computer system memory management. Virtual memory makes the application think that it has continuous available memory, but in fact, it is divided into multiple physical memory fragments, and some are temporarily stored on external disk storage for data exchange when needed.

75 Set the size of the virtual memory in the custom size area to 15 times to 3 times the thickness of the physical memory. Just make sure. 8 Notes This setting method is suitable for novices 92 In fact, it is not scientific to set strictly according to the multiple relationship of 153 times. It can be set according to the actual application of the system.
Set virtual memory reasonably. Under normal circumstances, Windows is allowed to automatically allocate and manage virtual memory. It can dynamically adjust the size of virtual memory according to actual memory usage. Memory settings mainly set the so-called virtual memory according to your memory size and the purpose of the computer. Memory is to use part of the hard disk space when the physical memory is insufficient; 3 Click Advanced Options, select Change 4 Uncheck the Automatically manage paging file size for multiple drives option 5 Click Custom Size and finally select OK to summarize the virtual memory settings size General It should be 15 times the physical memory. If the physical memory is 2G, the virtual memory should be set to 3G=3072MB; the virtual memory setting size should generally be 15 times the physical memory. If the physical memory is 2G, the virtual memory should be set It is 3G=3072MB. If the physical memory is 4G, then the virtual memory should be set to 6G=6144MB. My physical memory is 1G, then the virtual memory should be set to 15G=1536MB. Note 1G=1024; just set it to 15 times at 512MB. Above, set it to half of the memory capacity, between 256MB and 512MB. Set it to the same value as the memory capacity. If you don't know, you can also use the optimization master to set it. He will tell you how much memory you should set and how much virtual memory you should set. Better.
There is a recommended value at the bottom of the virtual memory setting page. If you really don’t know what the best setting is, it is recommended that the virtual memory be set to the recommended value.

The virtual memory size should not exceed 15 times your physical memory. If you do not play large-scale games with 4G memory or more, you may not need to set it because virtual memory consumes too much hard disk. Hello, according to the Windows memory management system, virtual memory is generally set to physical The memory is 12 times, for example, 2G is set to 4096MB, 2G memory is 2 times, 3G is set to 4608MB, 3G memory is 15 times, 4G memory is set to 4096MB, 1 times of 4G is not enough, and 68G memory or larger is automatically managed.
Virtual memory is generally a maximum of 2 times the real physical memory. Personal suggestion is that it is best to let the computer automatically manage the virtual memory, so as to avoid waste. If you just want to manually set the virtual memory, The size is no more than 2 times the real physical memory; the virtual memory setting size should generally be 15 times the physical memory. If the physical memory is 2G, the virtual memory should be set to 3G=3072MB. If the physical memory is 4G, then The virtual memory should be set to 6G=6144MB. Under normal circumstances, the virtual memory of WINDOWS is automatically managed by the system and does not require human intervention; just set it to 1G, not too large\x0d\x0aIn the default state, it is managed by the system Virtual memory, but the management method of the system's default settings is usually conservative. During automatic adjustment, the page file will be discontinuous, which will reduce the reading and writing efficiency, and the work efficiency will be low. Therefore, "memory is not enough" often appears; first of all, I am not Windows users, but virtual memory is not a concept that only Windows users will face, because virtual memory itself is a common concept at the operating system level. Before I talk about how to set up virtual memory, let me briefly talk about what virtual memory is. Let’s look at an example. There is such a program and we use this program.

The virtual memory setting is 1.5 times the memory.

Virtual memory is a method of calling hard disk space to temporarily serve as running memory when the computer's running memory is insufficient. For example, the computer's running memory is only 3G and the user needs to run 3.5G software. Virtual memory is needed to allow the system to use part of the hard disk space so that the additional 0.5G software can run.

It is generally a common recommendation to set the initial size to about 1.5 times to 2 times the physical memory. For example, if your computer has 8GB of physical memory, you can set the initial size from 12GB to 16GB. Setting the maximum size to 3x to 4x physical memory is a common recommendation. For example, if your computer has 8GB of physical memory, you can set the maximum size from 24GB to 32GB.

Virtual memory introduction:

Virtual memory is also called virtual memory (VirtualMemory). All programs running on the computer need to be executed through memory. If the executed program takes up a large amount of memory, it will cause the memory to be exhausted. To solve this problem, Windows uses virtual memory technology, which allocates part of the hard disk space for memory use. When the memory is exhausted, the computer will automatically call the hard disk to act as memory to relieve memory tension.

If the random access memory (RAM) required by the computer to run a program or operate is insufficient, Windows will use virtual memory to compensate. It combines your computer's RAM and temporary space on your hard drive. When RAM runs slowly, it moves data from RAM to a space called the paging file. Moving data into a paging file frees up RAM so work can be done.

Generally speaking, the larger the computer's RAM capacity, the faster the program will run. If your computer is slowing down due to a lack of free RAM, you can try to compensate by increasing virtual memory. However, the computer reads data from RAM faster than from the hard disk, so expanding the RAM capacity (by adding memory modules) is the best choice.

According to Microsoft's recommendations, the general virtual memory setting is 1.5-3 times the physical memory capacity. The general setting for 8G memory is 12GB to 24GB. It is recommended to let the system adjust dynamically.

Detailed introduction

1. According to Microsoft’s recommendations, virtual memory is set to 1.5-3 times the physical memory capacity, such as 512MB of memory, virtual memory. The memory is set to 768--1536MB. If it is 8G of memory, then the corresponding virtual memory is set to 12288MB-24576MB;

2. It is recommended to let Windows actively allocate and manage virtual memory. It can dynamically adjust the virtual memory according to the actual memory application. the size of. There is a recommended value at the bottom of the virtual memory settings page. If you really don't know what the optimal setting is, it is recommended that the virtual memory be set to the recommended value.

Key issues of virtual memory

(1) Scheduling problem: deciding which programs and data should be transferred into main memory.

(2) Address mapping problem: when accessing the main memory, the virtual address is changed into the main memory physical address (this process is called internal address conversion); when the auxiliary memory is accessed, the virtual address is changed into the auxiliary memory. The physical address of the memory (this process is called external address translation) for page change. In addition, issues such as main memory allocation, storage protection and program relocation must be solved.

(3) Replacement problem: Decide which programs and data should be transferred out of main memory.

(4) Update question: Ensure the consistency between main memory and auxiliary memory.

[Virtual memory] is a part of the hard disk space used by Windows as memory. The virtual memory is actually a huge file on the hard disk. The file name is , which cannot be seen under normal circumstances. You must turn off the explorer's protection function for system files to see this file. Virtual memory is sometimes called the "page file" from the file name of this file.

Initial size and maximum value of 8g virtual memory

1G=1024M, the minimum value is 8000MB, and the maximum value is 16000MB. However, if the memory is larger than 4G, the virtual memory system can automatically allocate it. If the setting is larger, the performance improvement will not be so obvious. The initial size of virtual memory is the minimum value allowed by the system, and the maximum value is the maximum virtual memory space set. Take HUAWEIMateBook, win10 as an example.

The minimum value of virtual memory that the system allows to be set is 2MB, and the maximum value cannot exceed the remaining space value of the current hard disk, and cannot exceed the memory addressing range of the operating system (for example, a 32-bit system can support a maximum of 4G memory ). Virtual memory cannot replace physical memory. Setting it too large will only bring down the system and take up corresponding hard drive space. 8G memory is completely sufficient for ordinary users, and it is not enough to add physical memory instead of virtual memory.

Minimum and maximum virtual memory values ​​can be obtained by using the Memory Manager program in System Monitor. Open frequently used programs in sequence. As you operate, the fluctuations in the swap file value will be displayed. Then check the performance values ​​in System Monitor. Because the situation of using the computer is different every time, it is best to monitor the swap file for a long time to find the most suitable value for the swap file, so as to ensure the stable operation of the system.
