How to Set virtual memory in Windows

Memory is an important component in the computer. All Programs in the computer run in the memory, so the memory performance has a great impact on the computer. If the number of programs executed is large or large, the memory will be exhausted. To solve this problem, Windows uses the virtual memory technology, that is, taking out a part of the hard disk space for memory usage. This part of space is called virtual memory, and the virtual memory format is PAGEFILE. SYS this page file. Www.2cto.com virtual memory is only a supplement to insufficient real memory. Its read/write performance (that is, hard disk read/write) is only a fraction of the real memory performance, it makes the application think that it has continuous available memory (a continuous and complete address space). In fact, it is usually divided into multiple physical memory fragments, some of them are temporarily stored in external disk storage for data exchange as needed. Some users may have several misunderstandings about virtual memory settings. Next, let's introduce them to you. I. Q: Shouldn't the virtual memory be located on the system disk but in other non-system partitions? A: Not necessarily. When setting the virtual memory, note that if you have more than one hard disk, it is best to set the paging file on the hard disk where the operating system or application is not installed, or the fastest speed among all hard disks. In this way, when the system is busy, the same hard disk is busy reading application data and performing paging operations at the same time. Of course, if you only have one hard disk, there is no need to set the paging file to another partition, the impact on performance is not great. Www.2cto.com II. Q: Is the optimal value of virtual memory 1.5-3 times the memory capacity? A: Yes. It depends on the actual usage. In particular, the popularity of large memory today. Memory usage is shown in the memory column of the task manager. Generally, the memory usage is 256 MB. You can set the virtual memory to 768-MB (the sum of memory + virtual memory is generally MB higher than the normal usage ). 1 GB memory, depending on the actual memory usage, you can set the virtual memory to 128-1024 MB (the sum of memory + virtual memory is generally-MB higher than normal), and so on. 3. Question: The larger the virtual memory, the better. Answer: error. The virtual memory is too large, which wastes disk space and increases the Head Positioning time, reducing the system execution efficiency without any benefit. Correct settings can save about mb-4 GB space (depending on the memory size ). Www.2cto.com


In Windows 7, right-click computer properties, click Advanced System settings, click the Advanced tab, and click Settings ].

Click [settings] In the performance tab ]. Then [change]

If you want to customize the size, you need to remove the check box before [automatically manage the size of paging files for all drives] And then customize the size according to your actual needs. The system will restart, so that the settings are complete.
