How to save Windows XP system memory

With the development of technology, memory is getting bigger and bigger, and many people have upgraded their memory to more than 1G. But nowadays, with the enhancement of functions, many softwares have a higher and higher occupancy rate of system resources, which has advantages and disadvantages. Although the change is fast, we are overwhelmed. But what should we do if there is such a problem? Let us talk about how to save memory better in the operating system, so that every resource can be used reasonably.

Let's take a look at it together, we can all use these settings to save memory.

Optimizing Memory Data

In Windows, the more data that resides in memory, the more memory resources are used. Therefore, the shortcut icons on the desktop and in the taskbar should not be set too much. If memory resources are tight, consider using as few background residing programs as possible. Do not open too many files or windows while you are operating your computer. After using the computer for a long time, if the computer is not restarted, the data arrangement in the memory may be confusing, resulting in a decline in system performance. Then you have to consider restarting your computer.

Enable Disk Write Cache

Right click on “My Computer" Select “Properties->Hardware”, open Device Manager to find the currently in use Hard disk, click the mouse [/url] right click to select the property. In the "Strategy" page of the hard disk properties, open “ Enable write caching on disk  (Figure 1).

This option will activate the hard disk's write cache, which will increase the read and write speed of the hard disk. However, be aware that after this feature is turned on, if the computer suddenly loses power, it may result in irreparable data loss. It is therefore best to turn this feature back on with a UPS. Of course, if you don't do any important data processing work when you use your computer normally, it doesn't matter if you don't have a UPS. This function will not cause too much damage to the system.

Turn off unwanted services

If you don't have a printer at home, you can turn off the “PrinterSpooler” service. If you do not have a regularly scheduled task, turn off the  quo;TaskScheduler” service. For most people, “RemoteRegistry” is also useless and can be turned off. Below is a list of all the optimized services above. I have optimized the places marked with red circles.

Open UltraMDA

In Device Management, select “Basic/Secondary IDE Controller” in IDEATA/ATAPI Controller, right click and select “Attributes” to open “Advanced Settings” page. The most important setting item here is “transfer mode”, generally should select “DMA (if available)”.

Monitoring Memory

No matter how big the system's memory is, it will always run out. Although there is virtual memory, since the read/write speed of the hard disk cannot be compared with the speed of the memory, when using the memory, it is necessary to monitor the memory usage at all times. A system monitor is provided in the Windows operating system to monitor memory usage. Generally, if only 60% of the memory resources are available, you should pay attention to adjusting the memory, otherwise it will seriously affect the running speed and system performance of the computer.

Configuring Recovery Options

When a fatal error occurs during Windowsxp operation, a snapshot of the memory is saved as a file for system debugging. For most normal users, this Files are of little use, but they affect the performance of virtual memory. So it should be closed.

Right click on “My Computer", select “Properties->Advanced", under "Performance", click “Set” button in “ In the Performance Options & rdquo; select “Advanced& rdquo; page. There is a “memory usage” option. If you set it to “System Cache” (Figure 2), Windowsxp will use about 4MB of physical memory as the cache for reading and writing the hard disk, which can greatly improve the physical memory. The speed of data exchange with virtual memory. By default, this option is turned off. If your computer has sufficient physical memory, such as 256M or more, it is best to turn this option on. But if physical memory is tight, you should still leave the default options.

Set Page File

Now go back to the setting dialog box of “Virtual Memory” and select the custom size and set the “Initial Size” and “Order” respectively according to the above calculation results. Maximum value & rdquo;. Generally, the initial size is 1.5 times the actual physical memory, and the maximum value is 3 times the actual physical memory. Such as: 512 physical memory changes should be: initial size: 768 maximum: 1536

change the location of the page file

Its purpose is mainly to maintain the continuity of virtual memory. Because the hard disk reads data by reading the magnetic material on the magnetic head, and the page file is placed in different areas on the disk, the magnetic head will jump and jump, which is not conducive to improving efficiency. Moreover, there are many system disk files, and the virtual memory is certainly not continuous, so it should be placed on other disks. To change the location of the page file: right click on “My Computer", select “properties → advanced → performance settings → advanced → change virtual memory & rdquo;, select the desired in the drive bar Go to the location. It is worth noting that after moving the page file, the original file will be deleted (the system will not delete it automatically).
