    Virtual Memory (XP)

    Lately I have started getting the following message "Virtual Memory Minimum Too Low" Can someone explain why this might be occurring and how I can fix it. I'm running Windows XP Home Edition on an Athlon 1.7 with 512 mb ram and my pc has been operating very slow of late.

    Thanks
    Dax

    Re: Virtual Memory (XP)

    Dax,

    I believe you're running low on registry quota. Windows allows only "x" amount of space for the registry and when you near the limit it starts acting like a miscreant. To change the allotted registry quota (and hopefully fix your problem) you'll need to do the following:
    1. <LI>Open the System properties, either through the control panel, Winkey+BREAK, or right-clicking My Computer and selecting properties
      <LI>Click on the Advanced tab
      <LI>Click on Performance Options
      <LI>On the new box that appears click on Change under Virtual Memory
      <LI>Adjust your registry size at the bottom of the dialog. A screen shot is attached with an example.
    If that doesn't fix it.....post back and we'll dig in some more! <img src=/S/crossfingers.gif border=0 alt=crossfingers width=17 height=16>

    Mark ~

    I do not have the 'registry size' section as it appears on your virtual memory window. Is this an optional setting or should this be showing??

    Mark,

    The only thing close to your description I found on my Win XPP machine was under the tab

    Mark--
    I can't figure out what you're doing to get the Registry size setting on the performance tab. I haven't seen it on mine or other machines.
    On the Advanced Tab in the Peformance Options box, before you get to the screen shot you took under "Memory Usage" you have the option to adjust for best performance of either Programs or System Cache. Do you have a preference or reasons for going one way or the other?

    Mark

    Unfortunately my excitement didn't last, as within a short time of changing my settings as you suggested, I started getting the same message again.

    Since then I have gone back and changed the settings 3 times to a higher MB value without success. I have also selected, "System managed size" again without success.

    I also like hlewton, defrag & brucekrymow don't have the "Registry size" section you mentioned. Mine is the same as theirs (See attached) So the settings I changed were in the "Paging file size for a selected drive" section.

    Have you any other suggestions.

    Re: Virtual Memory (XP)

    It looks as though Mark is using a third party skin or utility program that lets you manipulate the Registry Size Limit (RSL) parameter. I don't immediately recognize it but I did dig up some MSKB articles that you may find helpful.

    Re: Virtual Memory (XP)

    Did you implement Platform SDK to get the Reg get & read?

    Re: Virtual Memory (XP)

    You're close Ricky....actually, what happened was I checked on my Windows 2000 box, which has the option where I stated - and on Windows XP, which I checked later, it doesn't exist. The skinning program (WindowBlinds) has nothing to do with the option. This option was available in Windows NT 4.0 as well, so I just made the leap and figured (incorrectly) that it would be there in XP. Interesting that it's not - there was a bug in Windows 2000 regarding this option, so I wonder if that's why it became unavailable.

    For everyone interested, your best bet is to look through the article mentioned in Ricky's post: Q124594: Understanding and Configuring Registry Size Limit (RSL) and changing the setting there. Do not alter the setting if you're not having any problems - as with all things, if it ain't broke, don't fix it - unless you don't mind the possibility of troubleshooting later, if problems develop.

    Sorry for the confusion, everyone. That's what I get for not being thorough and double checking.

    Re: Virtual Memory (XP)

    <hr>you have the option to adjust for best performance of either Programs or System Cache<hr>
    Really, the answer to that depends on what you use the machine for, and your personal preferences. Setting it to Programs will result in snappier performance overall, using the Background Programs setting will reserve more memory for caching operations - useful when the machine is a server that doesn't have someone tapping away at the keys and reading email, etc. In other words, it's intended for servers that sit in a closet and run the same processes all the time, and that's where the benefit lies. Since the same programs/processes are running continually, their code is already loaded into memory and there is a faster response from the program itself. If you are opening/closing programs and windows (which is what 99% of people do with a desktop PC) then the setting is going to negatively impact you.

    If you have a large amount of RAM (512MB+) you can try changing the setting and rebooting - you can always change it back. I don't care for it on the Background setting; I want my console to be as responsive as possible, and the little performance hit that I take for changing that isn't worth it. At least, not on my desktop PC anyway. <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    Mark et al, The RSL does not exist in Windows XP. That's why the display looks different between 2k & XP.
    See Q292726 - Registry Size Limit Has Been Removed From Windows XP.
