question about virtual memory??????

Question

this warning came up on my computer:
"Your system is too low on virtual memory, windows is increasing your virtual memory, during this procces requests from other applications may be denied"
why did this come up?

thanks in advance!!!!
what does it mean?
how do i fix it???????

Answer 1

ignore it it will not affect any performance of ur pc
just ignore it

Answer 2

This means that you've run out of both physical memory (RAM) and virtual memory. Once all of your RAM is allocated, the system begins shifting blocks of high memory into a specially formatted area of your hard drive. When this happens, you'll generally notice your system slowing down pretty substantially, since the HD isn't nearly as fast as RAM. The virtual memory gets "paged" into designated section of RAM in blocks to be executed as those sections of memory are needed.

A simpler way to put it would be to say that Windows is causing a portion of your hard drive to emulate RAM, and do the job of RAM because you just don't have enough RAM to get the job done.

Probably the easiest way to get to the virtual memory settings is to right click "My Computer", hit "Properties, then "Advanced", then select the "Performance" settings button, then "Virtual Memory" change button.

Once in the virtual memory maintenance panel, the safest setting is to just let windows manage the space automatically. If you already have this set, and you're still getting errors, then the HD with the swap file is almost full. You can designate another drive, or manually set the quantity of disk space to be used by VM. It's generally faster for virtual memory to use a different physical drive then your boot drive. You'll get better virtual memory speed, that way. Most people just use their C drive, though, as many systems don't have a second physical drive, and there's no advantage to setting it to a different logical drive, unless that drive has more space.

Hope this helps.

You have on your computer what is called a Paging File, this buffers any active programs that you are running.

If the size of your paging file is not big enough to run all the programs you need to run, Windows compensates by increasing this paging file (adding more virtual memory).

You could fix it by adding more physical memory to your pc, add more RAM.

Answer 4

This happens when your RAM is insufficient for the applications you are running. If you run a bunch of apps at one time, they will all ask for RAM, and will eventually use it all up. Windows will then allocate a certain portion of your hard drive to act like RAM to make up for it. This is what virtual memory is.

Windows automatically adjusts the size of the allocation for your computer to work, so you really don't have to do anything. If you don't want to rely on your hard drive for RAM, you can get more ram here:

Answer 5

it means your computer is increasing its virtual memory ..nothing to worry about

just keep some space on c drive and d drive ..do not occupy your pc with unwanted programs that take up all space.

if you want to increase your virtual memory manually, that way you wont have your comp do it for you ...

Double-click on the System icon in the Control Panel. The System Properties dialog box appears.

Click once on the Advanced page tab at the top of the System Properties dialog box. Figure 1 shows this specific page of the dialog box.

Figure 1 Configuring your Windows XP system for higher performance using the Advanced tab of the System Properties dialog box.

In the Performance segment of the Advanced page (the first entry on the top of the page), click once on Settings. The Performance Options dialog box appears, as shown in Figure 2.

Figure 2: Using the Performance Options dialog box, you can define the virtual memory paging file size.

Click once on the Advanced tab of the Performance Options dialog box. Figure 3 shows the contents of the Advanced tab: Processor scheduling, Memory usage, and Virtual memory.

Figure 3 The Advanced page of the Performance Options dialog box gives you control over setting virtual memory sizing

Notice that at the bottom of the page there is an entry for defining the virtual paging size for your Windows XP system. Click once on the Change button. The Virtual Memory dialog box appears, as shown in Figure 4.

Figure 4 Using the options in the Virtual Memory dialog box to define paging file size.

The purpose of this dialog box is to define the size of the paging file your system will use. You can, for example, toggle Windows XP Professional to not provide any paging file by selecting the No paging file option (although it will save on disk space, it will inhibit your system's overall performance). The best selection in this area is to select System managed size because Windows XP will calculate the size of the virtual paging file for you. After you select the option you want for this specific option, click once on Set in the Paging file size for selected drive section.

Click once on OK to close the Virtual Memory dialog box; then, select OK in the two other dialog boxes until the main desktop is again shown.

Reboot your system, and PAGEFILE.SYS will be created. You'll notice that the file appears in the partition as defined in the Virtual Memory dialog box. Your system should now run more efficiently, especially when several concurrent applications are in use at the same time.

What is "virtual memory"?


Virtual memory is a common part of most operating systems on desktop computers. It has become so common because it provides a big benefit for users at a very low cost.

Most computers today have something like 64 or 128 megabytes of RAM (random-access memory) available for use by the CPU (central processing unit). Often, that amount of RAM is not enough to run all of the programs that most users expect to run at once. For example, if you load the Windows operating system, an e-mail program, a Web browser and word processor into RAM simultaneously, 64 megabytes is not enough to hold it all. If there were no such thing as virtual memory, your computer would have to say, "Sorry, you cannot load any more applications. Please close an application to load a new one." With virtual memory, the computer can look for areas of RAM that have not been used recently and copy them onto the hard disk. This frees up space in RAM to load the new application. Because it does this automatically, you don't even know it is happening, and it makes your computer feel like is has unlimited RAM space even though it has only 32 megabytes installed. Because hard-disk space is so much cheaper than RAM chips, virtual memory also provides a nice economic benefit.

The area of the hard disk that stores the RAM image is called a page file. It holds pages of RAM on the hard disk, and the operating system moves data back and forth between the page file and RAM. (On a Windows machine, page files have a .SWP extension.)

Of course, the read/write speed of a hard drive is much slower than RAM, and the technology of a hard drive is not geared toward accessing small pieces of data at a time. If your system has to rely too heavily on virtual memory, you will notice a significant performance drop. The key is to have enough RAM to handle everything you tend to work on simultaneously. Then, the only time you "feel" the slowness of virtual memory is in the slight pause that occurs when you change tasks. When you have enough RAM for your needs, virtual memory works beautifully. When you don't, the operating system has to constantly swap information back and forth between RAM and the hard disk. This is called thrashing, and it can make your computer feel incredibly slow.

Answer 6

computers have some actual memory calld RAM and together can use element of complicated disk as if it replaced into RAM (digital memory). you are able to evaluate digital memory as very very sluggish RAM. No lately 80 GB isn't sufficient. I truly haven't got any awareness about macs yet i ought to recommand a Intel center 2 Duo, with 2GB RAM, 250GB complicated disk,...

Answer 7

* this is a common thing you do mot have to do anything it just means windows is moving things you may help this by removing some thing of your hard drive as it may be getting full

Answer 8

Close some apps. Don't keep everything open.
