Myth 4. virtual memory should be set to 1.5 times the physical memory
this technique should be a lot more familiar veterans, its origin Probably in the era of Win9x. That is, by setting the virtual memory to 1.5~3 times of the physical memory, it is the most scientific setting method. However, you may have overlooked a small problem, that is, when this skill is popular, the computer memory is still between 32MB and 128MB. To tell the truth, which computer can afford a PC133256MB memory is already a very NB thing. . Under such a small physical memory, the usage of virtual memory is very high, so it is indeed possible to receive a certain effect by referring to the above-mentioned setting of virtual memory, which is what we often say to reduce the "memory bump rate".
but with the hardware performance by leaps and bounds, we are already into the GB era, now turn on a single computer configuration, 2GB, 4GB of memory has become standard. If you still have to comply with the above "norms", then virtual memory will undoubtedly be set to 4GB ~ 12GB. Let's not say whether there really is software that needs such a large swap space. Even if there is a hard disk according to the current mainstream SATA2 interface (its data read speed is about 100MB/s), it is necessary to completely read the virtual memory (in 4GB). About 40 seconds, not to mention the frequent reading and writing will inevitably lead to the "hard disk fragmentation", so the result is not slow.
say that for a long time, in the end how much virtual memory should be set appropriate it? I believe that due to the current computer configuration larger span, simply define a standard already not appropriate, the best way is to adjust by itself Win7 . Don't underestimate it, so Win7's tailor-made method can not only minimize the loss of hard disk space during system operation, but also intelligently expand according to the application (that is, when running some large programs temporarily) Win7 automatically expands virtual memory), and this is often more reliable than a fixed size that you rack your brains out.
Note: Do not use the same virtual memory of the initial value and the maximum value of the same, although in theory this approach can reduce a portion of the hard disk debris, but often cause a system error of some irregularities, but let the system The operation is more unstable. Myth 5.
protection system is tasteless
many users will readily switch off to protect the system at the beginning of the installation, that the addition of this feature in vain take up some resources, and there is not much use . In fact, this reason may be traced back to the 2000 Windows system. When Microsoft first joined System Restore in Windows Me, it hoped to help users reduce the difficulty of system maintenance. However, due to the lame design and WindowsMe itself, this feature has been criticized by many netizens.
However, with Caozuoxitong maturing, "System Protection" Win7 times already tackled the problems before, not only to provide protection to the system settings, but also to restore file versions at different times (ie "version of history." ). The most important thing is that Win7 allows users to freely set the disk space occupied by the system protection. Once the backup exceeds the quota, Win7 will automatically delete the old restore point for the new restore point, and the operation is very user-friendly.
Myth 6. The system of thin wooden
There are a lot of cheats warn the user, the system should always clean, and even a special on the network in order to facilitate the spread of a number of key clean-up tool. It is undeniable that regular system cleaning can improve performance, but the author here emphasizes that the concept of "garbage" is relatively broad. Some files may be useless, but they do not mean that others are useless. For example, the author has found two folders WinSxS and MSOCache in some cleaning tools. In fact, these two folders are bulky, but they are not useless.
where the former contains a number of important documents Win7, once mistakenly deleted is likely to cause a system crash, while the latter is "Local Installation Source" Office software (in fact, the Office CD backup on the hard disk), although Deleting it has no effect on daily use in a short period of time, but once the user intends to perform special operations (such as adding and removing components, installing SP package, repairing Office), it will lead to failure, and finally only the uninstall reinstallation path is optional. Therefore, the system must be based on their own circumstances, if in doubt, do not click on it or clean up!
Myth 7. Replace the files can get 4GB of RAM memory
now the price of cabbage Many players have directly loaded 4GB of memory at the beginning of installation. However, a very embarrassing reality is that 32-bit Win7 does not recognize 4GB of memory and can only recognize up to 3.25GB. In order to solve the confusion of large memory users, the Internet began to spread some methods to enable 32-bit systems to support 4GB by "cracking", but later proved that some software only changed the system display, the real memory was not utilized, but it affected System stability.
So if you really have 4GB of memory, it obediently into 64-bit Win7, after all, now a 64-bit system compatibility is good. If you still love the old 32-bit system, I suggest that you search for the RamDisk program. The clever thing is that you can virtualize some of the idle memory directly into a hard disk. With this high-performance "hard disk", we can not only put the virtual memory (Pagefile) in it, but also move the temporary folder (Temp) or IE cache (Temporary), enjoy the unparalleled advantage of the high-speed area of the memory stick. Performance experience. Perhaps this is more valuable than you have tried to add a 0.75GB memory space.
