What is virtual memory

June 9, 2011 - PRLog -- Now, the importance of memory is getting manifested. Run a program or game in general at least 64MB of memory in order to have more satisfactory results; If you want to run very smoothly, then we would consider installing more than 128MB of memory. However, considering the price of memory today, blindly buying memory is obviously not desirable. Of course, if conditions permit, to add memory capacity than other hardware upgrades to get better results. But if you has no economic power or because of other reasons not being prepared to increase the physical memory, virtual memory might play from targeting may bring unexpected gains.

First, what is virtual memory?

Windows operating systems to dynamically manage virtual memory swap file when run. Than the actual physical memory in order to provide more than the memory available for use, Win do ws occupied part of the hard disk space as virtual memory. When the CPU when requested, first read the information in memory. When the memory capacity is not enough time, Win do ws will be temporarily stored data is written to disk. Therefore, the computer's memory size is equal to the actual physical memory with "paging file" (that is, the swap file) in size. If necessary, "paging file" will use all available hard disk space. If conditions permit, you should apply this feature set as much as possible. Of course, if you can set yourself, then gets automatically set than Win do ws better results.

Second, the calculation of virtual memory

The size of your virtual memory settings before you think of how the "real setting." Some people recommend applying a conventional formula: the number of physical memory, 2.5, of course, is wrong. Application of this formula, for users with 16MB of memory should be set to 40MB; For users with 128MB of memory should be set to 320MB. Clearly, for users with less memory, he needs to have a memory capacity larger than the user settings more virtual memory. Want to see your machine to work in the case of memory, you should install the "System Manager." Open "Control Panel" window, click the "Add / Remove Programs", select "Windows Setup", select "System Tools" in the "System Monitor" item tick, and install it. Run "System Monitor" (Start → Programs → Accessories → System Tools → System Monitor), select "Edit", then select "Add item" in the "memory manager" in the right window to add "is the exchange file "and" swap file size. " At this time, "System Monitor" will show track icon. In addition, you can also "edit" item in the "Deleted Items" by deleting the unwanted items. Click the "Options" in the "chart" and set the "Update interval", according to the length of time you intend to monitor to choose. Be sure to confirm click "File" select "start recording", and record-keeping log (sysmon.Log) to your hard disk for later reference. If you want to get a better track to reference, it would need to do something to make your machine in the "pressure" under tasks, such as playing games, or run some big programs. The limits when running or playing Pai Demo Unreal Bo game, can help you determine the needs of "virtual memory" size. Of course, this "stress" test in the computer can recognize the circumstances, from the test results show that the ability to handle graphics and the "swap file size" related. After setting the "System Monitor", you can refer to "log" the. With "Notepad" to open "sysmon.Log" file. Where file size is expressed in bytes, we use 1048576 (1024 × 1024, which IBM) to convert. 125829120/1048576 = 120MB. You should get the maximum value calculation, the gap between the general and the calculated value does not exceed 5MB.

Third, set the virtual memory

Based on test results, set the virtual memory is generally two different methods. One way is to create a "long-term fixed" convert the file, and the other is to create a "semi-permanent" conversion file. Create a "semi-permanent" is that once the benefits of converting documents necessary, Win do ws convert the file size can be expanded, which would avoid the "memory" error. After the application, Win do ws and convert the file size will be restored to the initial (and minimum) size. If you want to create "long-term fixed" convert the file, then set the numerical values should be calculated more than 30-50MB of space left, and "maximum and minimum" standard set 150MB. Especially when the extra virtual memory requirements, "long-term fixed" to convert the file can prevent accidents from happening. In fact, the general, 150MB on the hard disk virtual memory should be able to cope with the additional memory needs. Once the method to choose, follow these steps:
1. Organize your hard drive, then restart.
2. Right-click on the "My Computer", select "Properties" item, choose "Properties" item.
3. Select "Virtual Memory" entry in the pop-up window, select "specify my own virtual memory settings." If you choose "long-term fixed" to convert the file, then said, according to the method above to set the value. If you select the "semi-permanent" conversion document, the minimum value as the setting (of course, the specific numerical values to determine the calculation), the maximum is your logical drive all the free space.
4. Restart for the changes to take effect. Note: You can also file "system.Ini" to set the virtual memory size. Click the "Start" pop-up window "Run" entry, type "system.Ini" after the hit ENTER. Under the Pai 386E nh Bo with "MinPagingFileSize, MaxPagingFi le Size & Paging-Drive =" place the converted file to set the hard disk drive, and convert the file the maximum and minimum value. This value is calculated in units of kB, use the method to convert MB 1024.

Fourth, to further improve the exchange of documents

After setting the virtual memory later, you can further improve it. Exchange of documents placed in the hard edge of the best, but unfortunately that comes with Win do ws Disk Cleanup program does not support, but you can do something like this NortonSpeed Disk Disk Cleanup tool. I advise you not to swap files on different partitions, because this will keep moving the hard disk heads, the waste of time and hard disk itself. Suggested that the swap file partition into the most commonly used, that is installed on Win do ws into the "C: \" go. In setting the virtual memory, change the settings have to change the hard disk swap file settings.
