I. Download and installation

Third, the most important thing is to activate the memory that windows does not manage.
First of all, due to the limitation of 32-bit system, a general 32-bit operating system can support 4g memory at most without special settings. Considering that the address of high-level memory is used by other hardware for historical reasons, it is typical like windows xp/vista.
The system can only recognize 3g to 3.5g, and the operating system can't use the memory beyond the recognition range of windows, so these memories are equivalent to waste.
An important advantage of using ramdisk is that it can identify and use these memories that are not used by the operating system. Although ramdisk can use memory that can be recognized and utilized by the operating system, it competes with the operating system for memory instead of
Make full use of resources.
The setup steps are as follows:
1. Open file->; memory
You can see the default memory management information.
Node available memory (MB)
0 2960
Estimated total available memory: 2960 MB
The system management BIOS reports that 4096 MB of main memory is installed in the system.
2. Point unmanaged-> deploy
Select Allow unmanaged memory.
Reserved(MB) will change the default 1 to something else, such as 10 or 100, and then click OK, a prompt will appear to successfully activate windows unmanaged memory, indicating that it has been set successfully.
Click Close to return to the memory information window just now, and you can see that the information has changed now:
Node available memory (MB)
0 4096
Estimated total available memory:
Windows managed 2960 MB
Unmanaged 768 MB
Total 4096 MB
The system management BIOS reports that 4906 MB of main memory is installed in the system.
Pay special attention to "unmanaged 768 MB" here, which is the total amount of memory that windows does not manage but ramdisk can use. When we create virtual hard disks in the future, don't exceed this size.
Close and return to the main window.
Four. Create a virtual hard disk
The preparatory work is finished, and you can finally start to create a virtual hard disk.
Point action-> Add, the next steps are as follows:
1. Prompt information, directly next.
2. Set the size of the virtual hard disk according to actual needs, such as 768M.
3. Clear the content, and set whether to clear the memory when deleting or reloading the virtual hard disk, which is not set by default.
4. Choose a drive letter, there is no special requirement, and personal preference likes to stay away from the drive letter currently used, such as Z drive.
5. Select the file system, generally ntfs. It is better to select the "Create '\temp' folder" at the back, otherwise, in some cases, the problem of formatting the drive letter of the virtual hard disk will appear after each machine restart. The second option is to choose whether to compress,
Generally do not choose.
6. Whether to save when closing. Here, you can choose whether to save the memory to the hard disk when you turn it off. If so, the content saved before the last shutdown will be automatically loaded every time it is turned on, which will be more convenient to use. But the disadvantage is that every time you turn it off, you have to save it before turning it on.
Loading requires a lot of file reading and writing operations, which will greatly affect the speed of system startup and shutdown. It is recommended not to select it first, and then set it when you are sure that you need this function and are willing to sacrifice the switching speed.
accomplish
This adds a new virtual hard disk, which can be seen in the main window of ramdisk. When I turn on the computer, I can find that the new drive letter has been recognized, and I can read and write like a normal disk.
Verb (short for verb) restarts the system.
This step is not necessary. After the virtual hard disk was successfully created in the previous step, it can be used normally. The reason for the restart is to verify whether the installation settings can continue to be effective after the operating system restarts, and it is very important that the operating system can start normally-be careful.
If the startup is slow or even crashes during the startup process, for security reasons, please use software such as ghost for mirror backup before installation.
Six optimization systems
After the memory disk is set up, it is to optimize the system and give full play to the role of the memory disk.
1. First, set the temporary folder directory of the system and tell the system and applications to write all temporary files to the memory disk, which can improve the operating efficiency of the system without worrying about the gradual increase of the temporary folder directory caused by the crash.
Right-click the "My Computer" and "Advanced =" environment variables on the desktop, and change the settings including "User Environment Variables" and "System Environment Variables" to Z:\TEMP. Remember, it is best not to use the root directory of z: as a temporary directory.
It is emphasized that only two paths mentioned in the article can be modified in the environment variable, and the modification must be confirmed repeatedly. If you modify the error or other options, the machine will restart the blue screen!
2. Changing ie's cache directory and telling IE to write all the temporary files generated when browsing the web to the memory disk can speed up IE's browsing. Select the setting of select tools = "Intel net option =" general = "in the browser to modify the cache directory of IE.
3. Other applications such as winzip need to be set separately, so it is generally easier to find the location to modify the settings. However, if these softwares are installed after setting the temporary folder directory of the system, they will generally be automatically adjusted according to the system settings and do not need to be modified.
4. Temporary files generated by the compiler, as all friends who have used visual C or Gcc know, will generate a large number of temporary files during the compilation process, ranging from a dozen megabytes. You can adjust the compiler settings so that the intermediate files generated by compilation are stored in the memory disk, which can greatly improve the compilation speed.
5. Now many friends use P2P software to download, such as electric donkey, electric donkey, BT and so on. One of the defects of these softwares is that the hard disk head moves irregularly because of multi-thread access, which may lead to hard disk head wear. But this disadvantage is not a disadvantage at all for memory disks. Because the memory disk has no mechanical movement of the head at all, remember to copy the file to the hard disk in time after downloading to avoid losing the file after restarting. (Remember, if you want to download songs and other files, please download them to the R disk first, and then be sure to save them. )
6. Open a temporary ftp server to distribute popular files. If the memory is large enough, you can put popular files on the memory disk, so you are not afraid of the problem of hard disk damage caused by multi-thread access to ftp.
Generally speaking, you don't need to restart to modify the settings. However, if another application is accessing Ramdisk, it needs to be restarted, so it is best to close the program accessing Ramdisk. It is worth noting that the cache of ie, if set to Ramdisk, will need to be restarted if the setting of memory disk is modified at this time. Because IE cache is opened by resource manager after login, IE will be occupied even if it is useless. The method is to log in to another administrator account, or modify the IE buffer directory (you need to log in again to modify the IE buffer). You'd better restart it after changing it.
7. Memory disk is used to simulate floppy disk drives with various capacities.
At present, many friends don't have floppy drives installed on their machines. However, some programs can only be run by floppy drive, such as making antivirus disk of Rising antivirus software, or some software can only be run after verifying the key disk.
The setting method is very simple, that is, the type of memory disk is set to be removable, that is, the type of floppy drive. Set the size of the memory disk to the required capacity, for example, an ordinary floppy drive is 1.44 megabytes, which is the size of 1440k, set the drive letter to A (other drive letters are acceptable if there is no special requirement), and then double-click the "Apply" button.
