virtual memory?

Question

what is the virtual memory of my pc ,, and how do i increas it ,,and what is the swap files and how to increas the sittings of my swap files ?

Answer 1

Windows XP uses 2 types of memory and they are the physical memory (i.e. RAM) and the virtual memory (a.k.a. paging file or swap file ). Most people are familiar with the former but not the latter. Loading any program or file requires memory. Oftentimes, the amount of RAM is insufficient. Windows XP’s solution to the problem is to convert a portion of the hard drive (i.e. ROM) to act like RAM. This is the virtual memory (a.k.a. paging file). Now, this is very important, the physical memory works much faster than the virtual memory. So, the key to optimizing memory use is to use up all the RAM before resorting to using the virtual memory.

Below, I illustrate several ways to optimize memory use. Some ways are straightforward while others are not so straightforward. As always, create a system restore point before changing any of the settings. It will save you from a whole lot of grief if things go wrong.


1.Keep Windows system core and drivers in RAM and not the virtual memory. If you have 512MB or more of RAM then this tweak will significantly boost performance. Follow these steps:
*

Start Menu > Run > type “regedit” (without the quotation marks) > [O.K.] (this will open Windows registry editor).
*

Scroll down to the following registry key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\Session Manager\Memory Management]
*

In the right side panel, right click any open space and choose New > DWORD value.” For the Name, enter "DisablePagingExecutive"(without the quotation marks) and set the Value to “1” (without the quotation marks). Next, on the menu bar, choose File > Exit. Reboot.

2. Optimize the size of the paging file. As a rule, the size of the paging file should be 1.5x the amount of RAM. If you have 256 MB or less of RAM then set the size to 384 MB. If you have 512 MB or more of RAM then set the size to 512MB. If you have 1 GB or more of RAM then set the size to 768 MB. Some computer experts suggest if you have 1 GB or more of RAM then you can try setting the size to 0 (i.e. don’t use a paging file at all). Follow these steps to change the size of the paging file.
*

Use an account with administrative privileges.
*

Right click My Computer > Properties > Advanced > under “Performance,” click [Settings] > choose the “Advanced” tab > under “Virtual Memory,” click [Change].
*

Choose “Custom size” and set the “Initial size” and “Maximum size” to the same value.
*

Click [Set] > [O.K.]. Reboot.

3. Set a fixed size for the paging file. Since the paging file is part of the hard drive, it can be fragmented like everything else stored on the drive. Therefore, for best performance, reduce fragmentation of the paging file. One way to accomplish this is to set a fixed size for the paging file. The steps to do so are mentioned above.

4. Relocate the paging file to its own partition or drive. Since the contents of the paging file are always changing, fragmentation is unavoidable. However, you can increase performance if you relocate the paging file to its own partition or hard drive. Using a separate hard drive is better than creating a partition on the existing hard drive. Windows manages a hard drive with only one partition better than one with multiple partitions. Follow these steps to change the location of the paging file:
*

Right click My Computer > Properties > Advanced > under “Performance,” click [Settings] > choose the “Advanced” tab > under “Virtual Memory,” click [Change].
*

Under “Drive [Volume Label],” choose the partition or drive where you want to store the paging file > [O.K.]. Reboot.

5. Defrag the paging file. There are a number of ways to defrag the paging file but I like to focus on only 2.
*

Defragging with SysInternal’s Page Defrag utility. You can download it at: (http://www.sysinternals.com/Utilities/PageDefrag.html). The website has instructions on how to use the utility. My recommendation is to use the “defrag at next reboot” option. There is no need to defrag after every reboot.
*

An alternative way to defrag the paging file is to use Windows’ Disk Defragmenter. First, you need to set the size of the paging file to “0.” Follow the direction mentioned earlier to change the size of the paging file. Next, go to Start Menu > All Programs > Accessories > System Tools > Disk Defragmenter > click [Defragment] (ignore the alert which says there is no need to defrag). After the defrag, change the paging file back to its original size.

Answer 2

Virtual memory is a portion of your hard disk that Operating Systems use to increase the amount of physical RAM in your computer. Generally your should increase the amount of RAM in your computer and not your virtual memory. Virtual memory is a lot slower. A swap file is just another name for pagefile which is basically Virtual Memory.

For a Microsoft Windows computer Virtual Memory settings are generally 1.5 times the amount of RAM you have installed in your computer.

Answer 3

computers have some actual reminiscence calld RAM and on a similar time can use area of no longer uncomplicated disk as though it became RAM (digital reminiscence). you could evaluate digital reminiscence as very very sluggish RAM. No presently 80 GB isn't adequate. I haven't any awareness approximately macs yet i could recommand a Intel center 2 Duo, with 2GB RAM, 250GB no longer uncomplicated disk,...

Answer 4

its not memory its cache stored information on your hard drive which is used when ever the RAM is really low and it does what we call a swap. When this happens then its called disk thrashing.

it is the amount of RAM/GRAPHICSCARD/VIDEO CARD IN UR COMPUTER.BUY THESE AND INSTALL THEM!
