window2003 Virtual memory problem 20

Shutdown: Clears the virtual memory page file.

This security setting determines whether virtual memory page files are cleared when the system is shut down.

Virtual memory supports swapping memory pages to disk using system page files when they are not in use. On a running system, this page file is opened exclusively by the operating system and is well protected. However, systems that are configured to allow booting to other operating systems may want to ensure that the system page files are cleared when this system is shut down.

This ensures that sensitive information in the process memory that may enter the page file is not used by unauthorized users who manage to access the page file directly.

Enabling this policy preserves system page files in the event of a clean shutdown. If you enable this security option, when hibernation is disabled on a laptop system, hibernation files (are also zeroed.

Virtual memory is a hard disk space that is used as memory to make up for the lack of RAM space on your computer. When the actual RAM is full (in fact, before the RAM is full), the virtual memory is created on the hard disk. When the physical memory is used up, the virtual memory manager selects the low-priority portion of the memory that has not been used recently and writes it to the swap file.

This process is hidden from the application, which treats the virtual memory as the same as the actual memory.

Technical details: For Intel IA-32 processors (including 386, Pentium, etc.), the memory address of the user application (process) accessing memory is virtual, and the CPU converts it to the actual physical memory address. When there is not enough physical memory, the operating system swaps out a portion of the memory that is not used in each process for the time being to a page file (swap file), and swaps the contents of programs that need to access the memory from the page file to the physical memory.

You are not filling in random numbers. The virtual memory setting requires the maximum value to be twice the minimum value. Once you've filled in the initial value, multiply the initial value by two and fill in the maximum value you get.

In general, the system virtual memory is automatically controlled by the system, which is the most efficient and does not need to be set separately.

If the virtual memory setting is large, it will easily cause lag due to the read and write speed when exchanging data between the memory and the virtual memory.

If the physical memory is too small for the computer, it is not advisable to increase the amount of memory by increasing the virtual memory, and it seems that the memory has expanded, but the speed of the hard disk is as slow as a snail relative to the memory, which will only affect the speed. The most reliable is to directly increase the speechless memory, usually set the virtual memory, set it manually, set the number of virtual memory is about 2 times the physical memory, for example.

2G memory, virtual memory set 4G, 4G memory, set virtual memory 6G

If it is 8G memory, set 6-8G for virtual memory

Set the virtual memory in the system properties setting, right-click on the computer - properties, open the advanced system settings, come out of the system properties - advanced - settings --- advanced --- change.

My Computer --> Properties --> Advanced --> Performance --> Settings --> Advanced --> Change (Select C drive first, then select No paging file in the page file size of the drive, click Settings.) Then see which disk has the most space, just select which disk in the drive options)--select the custom size in the page file size options of the selected drive--> the initial size is 1024--> the maximum value is 2048--- click Settings--> restart the computer.

Is the space set by your virtual memory small?

I'll give you the encyclopedia, which is very detailed. At least more detailed than me. Because there is always more than one reason.

If this is the case, I think there are several situations:

1.Your CPU doesn't match the motherboard, or rather, the motherboard doesn't support such a big feature. You may have a misunderstanding, think that the higher the memory, the faster the speed, the higher the CPU frequency, the faster the computer must be, in fact, no, these have to match the motherboard, if the motherboard only supports 4G memory, your 8G memory in the 4G will be wasted.

The same goes for CPUs.

2.It may be a problem with your driver, and the driver is not well matched, and this situation will also occur.

3.Problems with the system itself. Not much to say about this, there are too many reasons - -4There is also virtual memory, you just set one, you don't need to set it on every disk, generally speaking, if the C drive is large enough, just set it on the C drive!

5.This is the last thing I want to say, it's a virus -- I actually hate to talk about it!

I don't know the rest, you can try again.

For example, your memory 4G virtual memory set 2014-4028 , total.

A total of 8G is online, and you occupy more than 8G of memory, definitely.

Jam. You should set the virtual memory to a larger size in a non-system disk.

For example, 4028 - 6078m or larger.

It's useless for you to set all 4 districts to 4028, only recognize one district.
