Is virtual memory used when physical memory is insufficient? Can you turn off virtual memory when pl

The so-called virtual memory is when your physical memory is not enough, a part of the hard disk space is used as memory, but because the speed of hard disk transfer is much slower than the memory transfer speed, 2GB physical memory is enough in general, you can no longer set up virtual memory, but sometimes play large games, and open multiple programs at the same time, because of memory tension will also cause slow operation, or crash, if so, then it is better to set up virtual memory.

As for virtual memory, let's put it this way As long as the memory exceeds 2G, you don't need to set it, and the popular point is that it can be turned off.

Hard disk is generally stored files for example, the write speed is 2m s read speed is 5m s, if you add virtual memory, then some programs will be used, such as the usage is write read , so that the program may be very slow in reading hard disk data, because only the remaining rate can be used, cf, it is estimated that 1g memory can run, it should be very smooth There will be no jamming and so on, the program that does not occupy much memory, this is no problem, such as QQ and the like, can be turned off.

It's best not to turn off the virtual memory, as some programs may be turned off and some programs may be run with an error.

If you have enough memory, you can turn off the virtual memory.

2G memory to play CF in some other programs with small memory is no problem at all.

Virtual memory is a technology for memory management in computer systems. Just set it up again.

Virtual memory is a technology for memory management in computer systems. It makes an application think that it has contiguous usable memory (a contiguous complete address space), when in reality it is usually divided into multiple physical memory fragments, and some are temporarily stored on external disk storage to exchange data when needed.

In Windows, virtual memory is actually a file with a large capacity, called Sakura to take the page file. Page files have system and hidden properties that are normally invisible and can only be seen when the Hide Protected OS Files and Do Not Show Hidden Files and Folders checks are removed from the Folder Options dialog box.

Right-click on "My Computer" on the Windows desktop, click "Properties" in the menu, click Settings in the Performance column of the Advanced tab, and then select the "Advanced" option in the "Performance Options", and the virtual memory column will appear below. Clicking the Change button opens the Virtual Memory settings dialog box.

No, because some software has a bug in calling memory if you turn off virtual memory.

In the early days, computers had too little memory to be used, so a piece of hard disk space was created for memory, which was called "paging files".

Since the memory was really small at that time, almost all machines were unwilling to meet the memory needs, so when developing software, there was a specific set of steps to call the paging file.

In the following era, the memory has been expanded to a certain extent, and many machines have been able to fully meet the needs of the software for memory, but there are still some machines that cannot be satisfied, in order to ensure effective compatibility and stability, the tradition of paging files is still retained, which makes the software compatible very well, regardless of the high configuration of the machine or the low configuration of the machine can run stably.

Time has passed, and now the configuration memory of the machine has been unexpectedly large, but of course, software developers will not only consider these high-configuration machines, but also need to take care of low-configuration machines, so the tradition of paging files is still preserved today, but countless optimizations have been made to call the least paging files on high-configuration machines, but still need to be called.

If you turn off the virtual memory, then if the software needs to call the paging file, it will cause the software to not function properly or even the blue screen of death.

Therefore, in high-configuration machines, the virtual memory can be set as small as possible, but it cannot be left unset, in order to ensure compatibility.

There's also about disabling virtual memory, I've disabled it, there's no problem under Windows, but some programs can't run, and the game will be card-by-card anyway, wizards and gow are like this.

If you don't turn on the virtual memory, you will get an error.

There must be a thank you for the virtual memory.

You can use software to divide 1 GB of memory into disks. Place the location of the virtual memory on the disk where the memory is virtualized. That increases the life of the hard drive and increases the speed of the system.

4G of physical memory is really big enough. But virtual memory can't be completely absent either. When the system runs some programs, it still needs to use virtual memory. Just make the virtual memory value smaller.

It can be canceled, and for large amounts of memory, virtual memory doesn't help anymore.

It is possible to set up virtual memory, but the effect is not very obvious, there is better than nothing.

When we are running some large software, or just quit the game, we will often prompt "your virtual memory is too low" prompt, this situation is generally as follows: one: your physical memory is relatively small, and it is difficult to run large software; Two:

You can't run a lot of windows or play games when you can't allocate physical memory. When this happens, our system will use our hard disk space as virtual memory to perform some operations, so how to set up our virtual memory, here I will introduce my personal experience to you, I hope it will be helpful to you, of course, this is not really the solution to the memory problem.

The general principle of virtual memory settings: the minimum value of virtual memory is 1 to 1 times that of physical memory; The maximum value of virtual memory is 2 to times that of physical memory.

Step 1: Right-click on my computer.

Step 2: "Advanced" in the properties interface, "512 MB of memory" in the lower right corner is the physical memory, and we calculate the virtual memory value based on this value.

Step 3: Advanced settings in Performance below.

Step 4: Click "Advanced" again

Step 5: You can see the virtual memory at the bottom, and we click on the "Change" button

Step 6: This is the interface without setting up virtual memory.

Step 7: The virtual memory is generally set on the hard disk other than the C disk, choose the hard disk with a large amount of remaining space, then I chose the E disk, and then click on the custom size below.

Step 8: Enter the minimum and maximum values and click the settings button in the bottom right corner.

Step 9: A prompt will pop up to restart the computer, click OK.

Step 10: We need to make sure to restart the computer, if there are other programs running, you can click "No".

The next time we restart the computer, we can follow the above steps to see that the virtual memory has been set successfully.

The setting of virtual memory is only for some users with relatively low memory, and users with more than one gigabyte of physical memory do not need to set it.

Humility also teaches you that the system manages the size of the virtual memory.

Step 1: Click on the original virtual memory drive, then click "No paging files" below, and then click "Settings" on the right, which is to cancel the original settings.

Step 2: Select the "Drive" you want to set, click "System Management Size" below; application, just determine it all the way.

Once set, the next time you restart your computer, it will take effect.

No. Virtual memory is not used as memory, it is stored temporarily.

1. The mechanism of virtual memory is not to replace memory to run programs.

2. Virtual memory is to run a program, when the physical memory is not enough, first save some things in the physical memory that are not used temporarily, in the virtual memory, and then free up the physical memory to run the program. After running the program, free up the memory and read back to the memory what was saved in the virtual memory.

3. Therefore, virtual memory can only temporarily save memory data, and cannot replace physical memory.

When playing CF, it prompts that the virtual memory is not enough, so do it:

Virtual memory: 1. Right-click [My Computer] [Properties] [Advanced] tab, 2. Click [Settings] in the [Performance] column to continue clicking the [Advanced] tab, 3. Click [Change] in the [Virtual Memory] column to pop up the [Virtual Memory] dialog box, and you can set it.

4. Select [Custom Size], set 1024 in [Initial Size], and set 2048 in [Maximum] (cannot exceed the memory addressing range of the 32-bit operating system - including 4GB).

It is recommended to check the size of [System Management], so that it is easier for the system to allocate the size by itself, and finally click [Settings] to take effect. If necessary, restart your computer.

It is recommended that you move the virtual memory to a disk other than the C drive, such as the D drive. to reduce the pressure on the system disk.

Method: Still in the [Virtual Memory] dialog box, click the C drive label, and select [No paging size].

Then select the D drive label, select [Custom Size], and set [Initial Size] and [Maximum].
