128M memory should be set to how much virtual memory

16GB running memory, 24576MB virtual memory.

The setting size of virtual memory is generally times that of physical memory, and 16GB memory can be adjusted to 24576MB. If it is only used for office work, then the running memory is greater than or equal to 4G, and there is no need to set virtual memory. If you're playing games or doing other work, you can set up virtual memory to prevent the system from crashing.

The Windows Virtual Memory Settings page file can be placed on any online hard drive in the system. The size of this virtual memory is customizable and dynamically changing, requiring the initial size and maximum value to be set.

You can also choose not to manually assign it, and it will be automatically managed by the operating system; Of course, it can also be set to no page file, so that the system has no virtual memory, and the operation of the system may be affected as a result, so it is usually not set this way.

Key issues with virtual memory:

1) Scheduling issues: Decide which programs and data should be transferred to the main memory.

2) Address mapping problem: When accessing the main memory, the virtual address is changed to the physical address of the main memory (this process is called the inner address transformation); When accessing the secondary memory, the virtual address becomes the physical address of the secondary memory (this process is called the outer address transformation) in order to change pages. In addition, it is necessary to solve problems such as memory allocation, storage protection, and program relocation.

3) Replacement Issues: Decide which programs and data should be called out of Main Memory.

4) Update issue: Ensure the consistency of the primary memory and the secondary memory.

Under the control of the operating system, the hardware and system software solve the above problems for the user, thus greatly simplifying the programming of the application.

Hello dear, I'm glad to answer for you: Virtual memory is an area on the system's hard disk that temporarily stores content in unused memory. In general, the virtual memory should be set to about 2 times the physical memory.

So, if your computer has 16GB of running memory, then the virtual memory should be set in a range of between 24GB and 32GB. When your computer is running a large number of or more complex applications, virtual memory can provide additional memory support, which can help avoid it"Out of memory"bugs to improve the stability and performance of the system. Note, however, that setting up too much virtual memory will also result in a waste of hard disk space, so you should adjust it appropriately according to your actual needs.

In general, Windows can automatically allocate and manage virtual memory, and it can dynamically adjust the size of virtual memory according to actual memory usage.

Generally, the default virtual memory size is to take a range value, it is best to give it a fixed value, so that it is not easy to produce disk fragmentation, the specific value is determined according to the size of your physical memory, generally 128MB physical memory set 2 -3 times, 256MB set times, 512MB set 1-times, 1GB set times or not.

Common misunderstandings of virtual memory

Virtual memory should not be set in the C disk (i.e., the system disk), this statement is actually wrong, in the case of the remaining space of the C disk, because the system disk is the disk that reads and writes system files and page files most frequently.

The most time-consuming thing in this operation is the head addressing positioning, so if you set other disks, the time for cross-partition positioning will definitely be longer than the positioning time set locally on the C drive, so in fact, the virtual memory setting on the C drive is the fastest and most efficient.
