Recently, the topic that everyone often talks about is the large price reduction of DDR memory. DDR266 has plunged from about 400 yuan to 200 yuan. Many people have used 512MB or even 1GB of memory, so there is a view that is popular among some players. It is said that disabling virtual memory, prohibiting Windows page file exchange, and forcing command data to be processed in memory can speed up data reading and writing efficiency. Is this true?
depending on the application needs to set
I believe that this statement should be divided treat, not just disabled say is a good thing.
First, figure out what is "large memory" configuration. The original design of Windows uses virtual memory itself because physical memory is very expensive, generally does not exceed 128MB capacity, and requires hard disk space for temporary buffering - that is, you should use how much physical memory the application needs and the memory it actually owns. A comparison, if the actual memory is less than the application peak, you will run into trouble.
In general, if the amount of data to map large plane, 3D animation rendering a great job, you should not disable virtual memory; If you frequently need to print a document with a large number of pictures, prohibit virtual memory also makes The program has an error. Because the

software wants to generate a buffer file before printing, and then transfer it to the printer. When the image size is larger and the resolution is higher, the buffer capacity required is also large. I used to help the advertising artist. When I came out with the design, I encountered a situation in which I printed a picture and generated nearly 300MB of temporary files. Because Windows and the application itself also need a certain amount of memory to run, if you are 512MB configuration, disable virtual memory, it is very likely that the virtual memory is insufficiently reported midway, forcibly exiting, causing waste of printing paper and ink.
So, your task must be based application environment to decide whether to disable virtual memory. Even if you set the virtual memory size fixedly, you must be cautious. Otherwise, the virtual memory will be insufficient when running large application software. The whole system will become very slow due to the high CPU usage. Not so convenient.
consider factors
operating system under different operating systems, virtual memory settings are different or disabled, can not be generalized.
because architecture issues, Windows 9x /Me has 256MB of memory is greater than the inherent deficiencies, greater than the amount of memory, Windows 98 will start slow and unstable situation of. If you use large memory plus disable virtual memory, the instability factor will increase further. Windows 2000/XP can effectively manage a memory capacity of about 1 GB. If this number is greater than this number, it will be unstable, and it will vary depending on the motherboard BiOS model and chipset performance. In addition, the design of Windows itself is that once a process is found to be inactive, it will map the memory space allocated to it to the swap file, leaving as much physical memory as possible for other active threads. It is not the use of physical memory to start using the swap file. Because it is too late to wait until the physical memory is used up, it will inevitably cause data transmission and processing stagnation on the lower configuration machine. Therefore, in principle, virtual memory is forbidden to cause Windows abnormality. Even if there is no fault that cannot be run, the virtual memory will be frequently prompted. Please reset the cloud to make you feel overwhelmed. How
to disable virtual memory has a large capacity memory friend, if you really want to disable virtual memory run faster, in fact, can compromise "cheat" over Windows, it is to Part of the physical memory is virtualized into a physical hard disk:
1.Windows 98
You can add a sentence to Config.sys: DEVICE=C:\\WINDOWS\\RAMDRIVE.SYS 23000 /E( Please set it according to the partition where your Windows is located. This sentence is to use memory to create a partition by Ramdrive.sys. 23000 is how much physical memory you want to use. The unit is KB. If you have 1GB, you can set this number to 300000 to 500000 or so, that is, 300 to 500 MB, and then set the virtual memory to the virtual partition, the program runs completely in physical memory.
2.Windows 2000/XP
Must rely on third-party tool software to virtual physical hard disk, and then set the Pagefile.sys page file to the virtual disk to achieve the same effect; or You can add a sentence at the bottom of "[386enh]" in System.ini, ConservativeSwapfileUsage=1, let Windows use physical memory first, and try not to force the virtual memory swap file directly.
conclusion
I believe disable virtual memory to achieve the acceleration effect is very limited, with the default settings are generally more appropriate for Windows, especially Windows 2000 /XP default settings for virtual memory management is very Ok, try not to change it at will, otherwise it will be difficult to judge and analyze if something goes wrong.
about the memory of some of the fault analysis
Sometimes, Windows some tips and memory-related failures, and is not necessarily related to memory; and a number of seemingly unrelated failures and memory, but really memory Caused, very concealed.
example: You turn over a cluster size of the partition with Partition Master PQ tools like when the cluster is less than the default value, Windows 98 run ScanDisk may be reported out of memory, and in Windows 2000 and Windows XP It's normal -- that is, it doesn't matter with memory at all.
Another example: Sometimes boot into Windows, the system will prompt you to registry errors, whether the recovery, when you choose to restore, restart again, still with a hint of such a failure, but mostly memory or There is a problem with the heat dissipation, and you need to replace the memory or the fan.
Therefore, Windows prompts sometimes misleading, if the same fault occurs repeatedly, their tips can not be resolved, the likelihood of false positives should consider Windows
