[ShawnTRD]

Every time I try to set the Virtaul Memory it won't take. Any I missing something?

you cant set your minimum and maximum to the same size... it must be a range... minimum should be 1.5 times your RAM amount (you need 3072 min) and max should be 3 times you ram (you need 6144) however the max size is four gigs (aka 4096)(in xp i don't know about max in vista)... so set your max size to 4096 and your minimum to somewhere in the neighbor hood of 1024... ;)
better idea is to set it too "system managed size" which will probably give you the ratio you need... then set that ratio static :up:

This is not true. You can define upper and lower limits with the same value.

To answer the OP, the following MS support article (http://support.microsoft.com/kb/315270) explains how to work around your problem.

Hope this helps.

no go on the link... been having lots of problems with microsofts sites lately... maybe me :shrug:
anyway your right you can set it the same (had to test it...) but whats the point in setting it the same... doesn't that just limit the amount to a low amount? why would they give the option for a range if you could just set your max size...
Thanks for the info!!

The point is that this way is to reduce fragmentation. In certain usage scenarios - not usually seen by most users - it is possible to need to enlarge it but not have any contiguous space to do so in.

Realistically with the quantity of memory most computers have nowadays the chance of getting a page file that's so large that the upper limit is a problem is pretty small. You have to take into consideration what kinds of systems were around when XP was released... 5-6 years ago. 1.5x your installed memory gives you the opportunity to use .5x your memory worth of page file space and still have enough room to copy the entire contents of your ram on to your hard drive when certain events take place.


Because you can't access the link, here's the relevant data in it:

CAUSE
This error message may occur if Windows tries to create a paging file on an NTFS volume, but the System and Administrators accounts do not have the correct NTFS permissions on the volume.

Back to the top
RESOLUTION
To resolve this issue, give the System and Administrators accounts full control of the NTFS volume on which the paging file is configured. To do this:
1. If you are running Windows XP Home Edition, or you are running Windows XP Professional but you do not log on to a domain, start your computer in Safe mode.For additional information about starting your computer in Safe mode, click the article number below to view the article in the Microsoft Knowledge Base:
315222 (http://support.microsoft.com/kb/315222/EN-US/) A Description of the Safe Boot Mode Options in Windows XP
NOTE: If your computer seems to stop responding while Windows is loading your personal settings, press ALT+TAB to switch to the Limited Virtual Memory dialog box, and then click OK.

2. Click Start, point to Programs (or All Programs), point to Accessories, and then click Windows Explorer.
3. In the left pane, expand My Computer, and then click a drive that is configured to use a paging file.

To determine if a drive is configured to use a paging file:
a. Click Start, click Run, type control sysdm.cpl, and then click OK.
b. On the Advanced tab, click Settings under Performance.
c. On the Advanced tab, click Change under Virtual Memory.
d. Click a drive in the list, and then note the options that are selected under Paging file size for selected drive. A drive is configured to use a paging file unless No paging file is selected for that drive. If more than one drive is configured to use a paging file, click the first drive in the list the first time that you follow these steps. Click the second drive in the list the second time that you follow these steps, and so on.
e. Click Cancel, and then click Cancel to return to the System Properties dialog box.
f. On the Computer Name tab, note the name before the first period in the Full computer name box. This is your computer name. You will need this information in steps 5 and 6.
4. On the File menu, click Properties. Click the Security tab to view the current permissions.
5. Click Add, type computer name\system, and then click OK.
6. Click Add, type computer name\Administrators, click OK, and then click OK. Note that you must type Administrators, not Administrator.
7. Click System, and then click to select the Full Control check box. This automatically selects the other check boxes.
8. Click Administrators, and then click to select the Full Control check box. This automatically selects the other check boxes.
9. Click OK.
10. If you want to make changes to your paging file options, click Start, click Run, type control sysdm.cpl, and then click OK.
11. On the Advanced tab, click Settings under Performance.
12. On the Advanced tab, click Change under Virtual Memory, and then set the paging file options that you want.For additional information about configuring paging file options, click the article number below to view the article in the Microsoft Knowledge Base:
308417 (http://support.microsoft.com/kb/308417/EN-US/) HOW TO: Set Performance Options in Windows XP
13. Close the System Properties dialog box, quit any running programs, and then restart the computer.

The reason some set the same values for upper and lower limit is to define a fixed size. This can be useful if you want to prevent (reduce) fragmentation and/or drifting of the page file.

If set to a fixed size straight after a clean install, and provided you don't set deletion of the page file on shutdown, then it will stay in the same place (unless an offline defragmentation moves it). This means it that the page file will remain very close to the start of the disk, which is the fastest part for reading/writing.

Edit: beaten to it by a very cute looking cat :D.

no go on the link... been having lots of problems with microsofts sites lately... maybe me :shrug:

0. Internet Properties -> Security tab -> "Reset all zones to default level"
1. Flush DSN cache - "ipconfig /flushdns" (from command console or start -> Run)
2. Stop win updates (from services)
3. Delete SoftwareDistribution folder (C:\Windows\SoftwareDistribution)
4. Re-start updates. (from services)
5. Re-start computer.


Don't argue, just do it! :up:
