The viral seizures will occupy a large amount of memory space, resulting in the problem of insufficient memory in the system. Quickly go to anti -virus, upgrade the virus library, and then take the anti -virus measures!
. Improper virtual memory settings
Improppy virtual memory settings may also cause insufficient memory. Generally, In the case, the size of the virtual memory is twice the size of the physical memory. If it is set too small, it will affect the normal operation of the system program. Taking the size of the virtual memory as an example, right -click "My Computer", select "Properties", and then click the "Settings" button in the "Performance" box to switch to the "Advanced" tab page Then click the "Change" button in the "Virtual Memory" box, then set the virtual memory size, and restart the system after completion.
3. The system space is insufficient
The virtual memory file is in the system disk, such as WinXP's virtual memory files "Pagefile.sys". Too small, resulting in insufficient virtual memory and insufficient memory. At least 300MB of remaining space should be retained in the system disk. Of course, this value depends on the actual needs of the user. Users try not to install a variety of application software in the system disk to ensure that there is enough space for virtual memory files, and it is best to place virtual memory files into non -system disks.
4. Instead of setting of System user permissions
When the NT kernel -based Windows system starts, System users will create virtual memory files for the system. Some users use the NTFS file system for the system's security, but the authority of System users "write" and "modify" the System users in the system disk cannot create virtual memory files for the system. When running large programs, there will The problem of insufficient memory. The problem is very easy to solve, as long as the System users "write" and "modify" the permissions, but this is limited to the user who uses the NTFS file system.
Optimization of virtual memory
1. Enable disk to write cache
right on "My computer" and right-click "Properties- > Hardware ", open the device manager to find the hard disk currently in use, right -click the mouse button to select the attribute. In the "Strategy" page of the hard disk attribute, open the "Enter the Cacus on the Disk".
The option will activate the cache of the hard disk, thereby increasing the read and writing speed of the hard disk. However, it should be noted that after this function is turned on, if the computer suddenly power off, the data may cause irreparable data. Therefore, it is best to open this feature with UPS. Of course, if you do n’t do any important data processing work when you usually use your computer, it does n’t matter without UPS. This function will not cause too much loss to the system.
2. Open Ultra MDA
In the "Basic/Second Idee Controller" in the device management. Attribute, open the "Advanced Settings" page. The most important setting items here is the "transmission mode", which should generally be selected "DMA (if available)".
3. Configuration recovery options
Windows XP will save the memory snapshot as a file when running a fatal error in order to use For most ordinary users, this file is useless, but it will affect the performance of virtual memory. So it should be closed.
Right-click on "My Computer", select "Properties-> Advanced", click the "Settings" button under "Performance", and select "Advanced" in "Performance Options" Page. Here is a "memory use" option. If it is set to "system cache", Windows XP uses about 4MB of physical memory as a cache for reading and writing hard disks. This can greatly improve data exchange between physical memory and virtual memory. speed. By default, this option is closed. If the computer's physical memory is sufficient, such as 256M or more, it is best to open this option. However, if the physical memory is tight, it should still be retained to the default option
The virtual memory is the space for the computer to take out a part of the hard disk to act as the memory. When the memory is stored, the CPU will automatically call the space of the hard disk to act as the memory to alleviate the memory space. For example, if the computer has 200MB physical memory, when a file occupies a 300MB of 300MB, a relatively large virtual memory must be used. After the file is read by memory, it will be stored to the virtual memory first. After the virtual memory, the file stored in the virtual inner will be released into the original installation directory!
. That is to say, the virtual memory is on the hard disk,
The right -level performance of my computer is high -level virtual memory change
is generally better than the original. The value is 1.5 times!
The concept of virtual memory is relative to physical memory. When the physical memory space of the system cannot be eased, the operating system will open a disk space on the hard disk as a memory to improve the operating speed of the computer. This part of the hard disk space is called Virtual Memory. Windows 98 uses the form of Win386.SWP file, while Windows 2000/XP uses the form of page file pagefile.sys to manage virtual memory. Since the virtual memory is different from the real physical memory, it is part of the space of the hard disk to temporarily store the information. Too unchanged operations are unavailable. It is recommended to add a memory barrier to solve the problem of insufficient memory. In general, it is recommended to make Windows from motion allocation management virtual memory. It can dynamically adjust the size of the virtual memory according to the actual memory. The minimum virtual memory uses users with a minimum value of 128MB or less memory. It is recommended to set the current physical memory capacity of 1.75 times to minimum value of the page file. There are users from 128MB to 256MB. It is recommended that the current physical physics will The memory capacity of 1.5 times is set to the minimum value of the page file. It is recommended to set the current physical memory capacity to the minimum value of the page file. Generally speaking, the maximum value of the page file is set. It is recommended to set 2 to 3 times the minimum value. If in the physical existence of more than 512MB, the maximum and minimum value of the virtual memory can be set to 0.5-1 times. The virtual memory setting method is: Right-click my computer-attribute-high-level-performance settings-high-level-virtual memory change-select the system disk formation in the driver list-custom size-in the size-in the size of Set the value in the "initial size" and "maximum value", then click the "Settings" button, and finally click the "OK" button to exit.
It can increase virtual memory method: Right -click my computer -attribute -advanced -performance -setting -advanced generally set to 1.5 times the total memory
