Do I need virtual memory if I have a large memory?

For users with large amounts of physical memory, virtual memory can be disabled entirely. To understand this issue thoroughly, we must first understand what virtual memory is and what it does. In the early days, because memory was very expensive, it was not usually configured too much on the computer, so sometimes if the operating system and applications needed more memory than the amount of physical memory installed in the computer, the operating system would temporarily write the data that did not need access to a special file on the hard disk through an operation called "paging", thus freeing up memory for programs and data that needed to use the memory immediately.

This special file on the hard disk is called a paging file (also known as a virtual memory file or swap file). For Windows 2000 XP 2003 operating systems, the paging file name is located by default in the root directory of the partition where the operating system resides.

Now that they know the origin and function of virtual memory, those who hold this theory believe that the speed of hard disk and memory is very different, and if virtual memory is disabled, the system does not need to spend time paging the data in memory to the hard disk, thus improving the efficiency of the system. You have 4GB of RAM, and you can't use it if you set up virtual memory.

There is no need to set up virtual memory at all, and there is no need for more than 1G memory.

You drop, you can drop.

It's not needed, and the virtual memory comes from the hard disk, so the speed is naturally far behind, and it's basically useless ......to set it up

You don't need to set it up, your memory is large enough, and even if you set it, there will be no problem! But not more than times the physical memory of the system!

Yes,My current memory is also 4G,I've tried a lot of ways to not use virtual memory,But at a certain time, the computer prompts that the virtual memory is insufficient.,This may be a matter of XP operating system.,After all, I think the memory capacity of the year is not very large.。 However, it can be set a little smaller. In fact, although it is 4G memory, the system would rather waste memory than use virtual memory.

Unless Microsoft comes with a patch for a large memory can not use virtual memory, if it is a new operating system it may work.

Yes, there is no need to set it up.

Virtual memory is necessary to be turned on.

Virtual memory can be regarded as the "warehouse" of physical memory, because its essence is still a hard disk, so the read and write speed is much slower than physical memory, and the data that is not used frequently is placed here, which is not greatly affected by the speed, while the physical memory stores the data that is often used, which can make the system run more efficiently.

Many large-scale 3D modeling software requires a large amount of memory to ensure efficient operation, and sometimes the browser will also take up a lot of memory, and having sufficient virtual memory can make the system more smooth.

Even if you don't use large software, you won't open more applications, and turning on virtual memory can get high-tolerance address obfuscation, more powerful process fork cache, optimized memory splitting and error correction, etc., and the hard disk capacity itself will not occupy a lot of cost, so it is still cost-effective.

Memory setting tips

If the physical memory is large enough, and you often use large-scale 3D mapping software without starting the chain, and do not often play triple-A masterpieces, the virtual memory can be set to 512-1024MB. If the physical memory is only 8G or even 4GB, and you need to run large software to play large games, it is recommended that the virtual memory be set to times the physical memory.

After the setup is completed, click on the button to confirm, note that you need to restart the computer to take effect. If the space of the C drive is limited, you can also set the virtual memory under a different drive letter. Finally, I would like to remind you that the virtual memory is not set as large as possible, but should be set according to your actual use environment and hard disk capacity, so that the computer has a better running environment.

Need.

For manual setting of virtual memory values, the recommended values in the following prompts are generally used as references. For example, Brother Plumb's computer here is recommended to be 2931MB, when the hard disk space is abundant, you can fill in this value on the "initial size", twice this value, that is, 2931*2=5862, and fill in 5862 in the "maximum value".

Generally, by default, the remaining space of the C disk is used to make virtual memory, so the larger the remaining space of the C disk, the better the system operation, the virtual memory is dynamically changed with your use, so that the C disk is easy to produce disk fragmentation, affecting the system running speed, so it is best to set the virtual memory in other partitions, such as the D disk.

How it works. Virtual storage is automatically scheduled and managed by hardware and operating systems.

**The logical address of the processor accessing the main memory is decomposed into group number A and group address B, and the address transformation of group number A is carried out, that is, the logical group number A is used as an index and the address transformation table is checked to determine whether the group information is stored in the main memory.

If the group number is not in the main memory, check whether there is a free area in the main memory, if not, then transfer a temporarily unused group to the secondary memory, so that this group of information can be transferred to the main memory.
