Win8 How to set up virtual memory, WIN8 virtual memory How to set the best?

Virtual memory is a memory control program, it is responsible for the system running all the programs of the cache, if it is currently in use, the program's data directly cached in memory, if a long time did not operate but also did not close the program is stored on the hard disk, No matter where the virtual memory is stored in a virtual contiguous place, more convenient system calls. For the WIN8 system, if the corresponding system in the physical presence of more than 2GB, I think the virtual memory is not necessary to set up, this can improve the performance of the system, if the physical presence of 2GB below, can be set according to the actual situation.

When you set up virtual memory, you can right-click the computer icon on the System desktop, click Properties on the shortcut menu, go to the System Properties interface, press the Advanced System Settings button in the left area, and enter the Advanced System Properties dialog box.

Click the "Settings" button at the "Performance" location to expand the Performance Options dialog box, select the Advanced tab, and click the "Change" button in the "Virtual memory" location of the corresponding label page.

The pop-up Virtual Memory dialog box removes the "Automatically manage paging file size for all drives" tab and clicks "Custom Size" to set the appropriate virtual memory size as needed.

--Virtual memory settings how appropriate

1, if your memory is less than 4G, it is recommended that the virtual memory set to 1.5 times times or twice times your physical memory;

2, if your memory 4g-8g, then can be set to 1 time times or 1.5 times times your physical memory;

3, 8G or more, can be set to 1 time times or set to 8G physical memory.

The role of virtual memory

and virtual memory, as the name implies is not the memory of things as memory. In fact, it is used as memory. But a very serious problem is that the speed of external storage is much slower than memory, so virtual memory increases the available memory to some extent but reduces the memory response speed in general.
So why use virtual memory? What's the use of it? The size of the memory directly determines how many programs our computer can run, and the system will change cards when the program that runs exceeds the memory size. And the advent of virtual memory to a certain extent to expand the size of the memory, so that the computer can run more programs.

How much is the virtual memory setting appropriate?

So the other problem is that the bigger the virtual memory, the better? Of course not, at least not under Windows. Virtual memory Although the dry memory of the live but after all is external storage, so the response speed is very bad. Another problem appears on the Windows system. The principle of allocating memory and virtual memory for Windows systems is to treat random writes of data as equals. In other words, the memory and virtual within the Windows system is equal, when the input needs to write to memory will be randomly written to memory or virtual memory. The larger the virtual memory, the greater the probability that the data will be written to virtual memory, and the result is that the system's average response rate is reduced. So do not set the virtual memory too large, especially hard disk performance is not very good time. Of course, there are many extreme ways, for large memory users can completely disable virtual memory. In my 8GB there is no problem with Windows7 after disabling virtual memory, the application response speed will be greatly accelerated.

So how much is the size of virtual memory appropriate? My personal advice is not to exceed 1.5 times times the physical memory, and not to step back more than twice times. The speed of the hard disk also affects the optimal size of the virtual memory. For solid-state hard drives or 10,000-speed hard disk, virtual memory can be slightly larger, and for our 7200 ordinary speed hard drive is the best moderate point, and the use of 5200 to drive the students as small as possible ... In addition, it is not recommended to disable virtual memory, of course, the technology can be better. After all, the likelihood of disabling a memory overflow with virtual memory is increasing, and some programs do have problems ...

There is also a small trick is if the virtual memory set to the U disk speed back slightly faster. The reason is that U disk as the external memory although read and write speed is not comparable to the hard drive but random read and write faster than the hard drive much faster. and random Read and write speed is the key to affect the performance of virtual memory, so use U disk when virtual memory can really speed up the system, but the truth, very limited, and will reduce the life of U disk, so be careful oh

Computer virtual memory set how much appropriate, not the bigger the better

Computer virtual memory, not the larger the better, preferably by system hosting, is the best effect. If you want to adjust yourself, you need to pay attention to reasonable settings. Memory capacity, Microsoft's recommended value is 1.5-twice times the physical memory. Self-setting can be tolerant to 2-4 times, no need to be big. To be big is to waste.

Virtual memory, aka virtual Memory (Memory). The computer that runs the

Programs need to be executed through memory, and if the program that is executing consumes a large amount of memory or a lot, it can lead to memory exhaustion. To solve this problem, Windows uses virtual memory technology, which is to absorb a portion of the hard disk space to act as memory. When memory runs out, the computer automatically calls the hard disk to act as memory to ease memory tension. Windows uses virtual storage for compensation if the computer is running low on random memory (RAM) required to run programs or operations. It combines the computer's RAM with the temporary space on the hard disk. When RAM is running at a slow rate, it moves data from RAM to a space called a paging file. Moving data into a paging file frees up RAM to complete the work. Generally speaking, the larger the RAM capacity of the computer, the faster the program runs. If the speed of the computer slows due to the lack of available RAM space, you can try to compensate by increasing the virtual memory. However, the rate at which the computer reads data from RAM is faster than the speed at which data is read from the hard disk, so expanding RAM capacity (plus memory bars) is the best choice.
