Virtual Memory

Virtual Memory is the HDD space to use some parts as a memory. This is an application used to store data and instructions that are not currently needed for the process by the computer system. During the process of loading the program, the system will copy the application data and instructions from the HDD to the main memory (system memory). Therefore, the system can use resources such as CPU to process and implement it. After getting the full system memory, the system will start moving some data and instructions that no longer need to process to the Virtual Memory to data and instructions they need to process again. So the system can call the next application of data and instructions and copy it to main memory for the system to process the rest and load the program. When the data and instructions in the Virtual Memory needs to process, the system will first check the main memory for space. If there is space, it will simply swap them to the main memory. If no space is left for the main memory, the system will first check the main memory and move any data and instructions that do not need to process the Virtual Memory. Then the exchange of data and instructions that need to be processed by the system of Virtual Memory to the main memory.

After too low on the size of Virtual Memory or Virtual Memory size (which means the size of which is above two times the memory system) is not a good idea. If you set your Virtual Memory is too low, then the OS will continue to emit an error message that states either not enough or Virtual memory too low. This is because some parts of the system memory used to store the OS Kernel, and the need to remain in main memory all the time. Therefore the system must have space to store the current process data and instructions are not needed when the main memory can be filled. If you set your Virtual Memory size is too large to support intensive applications, is also not a good idea. Because it will create lag performance, and even he would take the HDD free space. System requirements for data transfer and application instructions back and forth between Virtual Memory and Memory System. Therefore, it is not a good idea. The ideal size for Virtual Memory Virtual Memory is the default size, and must not exceed the value of triple the size of system memory.

To determine how much virtual memory you need, because the user's system contains a different amount of RAM, is based on the system. By default, the operating system will determine the right size for Virtual Memory. Standards and the appropriate size Virtual Memory is:

CODE * 1.5 =.
For example, if your system has 256 MB of RAM, you must assign 384 MB for Virtual Memory.
CODE 256 MB of RAM (Main Memory) * 1.5 = 384 MB for Virtual Memory

If you want to determine how much virtual memory for your system and / or want to configure and add virtual memory, follow the procedures that will be shown below.

The following procedure is based on Windows XP Professional.

1-1) to right-click My Computer and select Properties

1-2) In the System Properties dialog box, open the Advanced tab

1-3) Click the Settings button from the Performance frame

1-4) After the Performance Options appear on the screen, go to the Advanced tab

1-5) Under the Advanced tab, click the Modify button from the Virtual Memory frame for access to the Virtual Memory settings

Then the Virtual Memory dialog box is displayed. There, you can check how much Virtual Memory you specified.

If you want to change the size of Virtual Memory, follow the procedures that will be shown below.

2-1) There, select the drive letter that is used to install the Operating System

2-2) Choose the option that says, "Custom Size:"

Once you choose that option, the settings for the Initial Size and Maximum Size to be available for you to manage. Initial Size (MB) means the actual size of Virtual Memory, and Maximum Size (MB) means the maximum size of Virtual Memory that is allowed to be used.

Say if your system has 512 MB of RAM, then the ideal setting for Virtual Memory is as follows:

CODE

Initial Size (MB): 768 Maximum size (MB): 1500

Once you are satisfied with the size of Virtual Memory, click the Set button from Paging file size for selected drive to apply the settings for Virtual Memory size. Then click the OK button to apply the settings.

That's where you can manage and configure for the Virtual Memory size.

Additional Information.

To maintain good overall system performance, you should use the actual size of the standard size for Virtual Memory and three values of the size of main memory to the maximum size of Virtual Memory. If you find that the main memory plus virtual memory is not large enough to load intensive applications, then you will need to add main memory to your system.
