How do I prevent inactive ram

I've discovery through Activity Monitor that all my ram is inactive whenever I awake from sleep.  Running apps are safari, itunes, CS6 and Bridge.  There's 32GB ram so that a lot for these apps.  How can I prevent this? 
Below are screen shots before and after purge command.

Inactive RAM is not a disease. It is made up mostly of Disk data read by the system, which is being preserved momentarily in case you need it. (why waste it, if it has already been read.)
It is instantly turned into Free RAM when the System needs more.
Much more important for performance is PageOuts and Swap used. Both of these numbers on your graphs are extremely modest.
You are fine. Live long and prosper.

  • How do i get more RAM in my iMac G4 800?

    I'd like to expand the RAM on my iMac G4 800. I read a few discussions and am not quite sure what I can do. Here is what I have and what I want to do:
    Have: I have a iMac G4 800 with 512 in the J22 slot and 256 in the J20 slot. I am assuming the J20 slot is the one I can make changes to. Is that right?
    Want: I'd like to add a 1 GB DRAM and make my memory 1.5 GB. I realize there is some debate about whether this machine can handle over 1 GB of main memory. So, can I do that?
    Thanks

    Hello and Welcome to Apple Discussions. 
    I'm afraid there is no debate: 1GB is the maximum on the 800MHz iMac.
    Personally I don't believe that going from 768MB to 1GB is cost effective on this older Mac given that you will have to throw out a 256MB module.
    On my iMac G4 J20 is the internal "Factory" slot which is difficult to access; this notation may be different on the 800MHz model.
    Some tips to improve performance:
    Quit Safari often; it suffers serious memory leaks that Apple doesn't seem in a hurry to fix and will gobble up your RAM.
    Keep your hard disk nice and empty. Once you fill your hard disk above the 85% level you'll start to get fragmentation and the available space for virtual memory is not there.
    Use a system maintenance application like MacJanitor (link).
    Quit applications when you're not using them.
    Have a look in Macintosh HD > Applications > Utilities > Activity Monitor. How much Free and Inactive RAM do you have? If the processor regularly being tasked to 100%? How many Page Outs do you have?

  • Inactive RAM not being used/freed

    As I type this, my other computer has 590mb of inactive RAM, with 2mb of page outs and 11mb of page ins. Shouldn't the almost 600mb of inactive ram I have start being used instead of page swapping so much?

    The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
    Adding RAM only makes it possible to run more programs concurrently.  It doesn't speed up the computer nor make games run faster.  What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent.  It will improve the performance of applications that run mostly in RAM or when loading programs.

  • I have downloaded Firefox 4.0 several times and after a short amount of time (days) it reverts back to 3.6.16. Why does it happen and how do I prevent it from happening again?

    The Firefox 4.0 on my laptop reverts back to 3.6.16. This has happened several times. Why does this happen and/or how do I prevent it from happening again?

    Thanks for the link. I just downgraded to the absolute shtfest that's 4.0. I WAS just fuming about how gawdawful this "new" version is, but after wasting so much time trying to sort thru all the issues caused by this 4.0 downgrade (past updates have always been seamless and troublefree - not so for this shtfest!) I'm flat-out RAGING!!! Fortunately the laptop still has 3.6.xx running - it's the LAST version of Firefox it will EVER see. I switched to Firefox so many years ago to get away from the insanity and frustration of Explorer - if this 4.0 crapshoot is the "future" of Firefox, then the incompetent nimrods responsible for it know where they can ram it. I'm starting the search for a new browser now - so long Firefox, it's been fantastic while it lasted, but you've gone and screwed the pooch, you've ruined a superb browser!
    I'll attempt a reload of 3.6.xx on the desk machine, and if successful I'll run it till it drops, or I find a suitable replacement browser, but 4.0 won't be coming back - GOOD RIDDANCE!!!

  • How do I prevent Mac App Store flagging updates?

  • Too Much Inactive RAM, Too Little Free RAM

    I used to have a 2007 iMac running Snow Leopard, and I switched to a 2011 iMac running Mountain Lion. On both of my computers, I kept running out of free RAM after a while, and my inactive RAM kept taking up all my free RAM. It still does it. I end up with around 30MB of free RAM, a reasonable amount of active RAM, and a massive amount of inactive RAM after a few days, then my computer slows down a lot.
    I have to keep flushing the inactive RAM with a memory cleaning tool or else my computer slows to a crawl. Repairing the permissions is supposed to clean out the inactive RAM (thanks, Tuttle), but alarmingly, this doesn't work for me. There must be something causing this problem, and I want to find it. How do I do this? Can processes currently running be using inactive RAM, or is that only possible if they have just been closed? Is there a tool that can check how much inactive RAM is allocated to each process?
    P.S. To make it clear: I know that I'm not supposed to worry about inactive RAM and let the system do its own optimization, but it must not be doing it right because it's causing extremely noticeable slowdowns. The computer is like a Geo Metro pulling a whale if I don't flush the inactive RAM periodically.

    Since you are so concerned, take your iMac to your local AS or an AASP for a FREE diagnostic test.  At least you will have piece of mind when you get a confirmation of what is really going on.

  • Question -  how i can prevent assembly order rescheduling when in VA02 ?

    Hi                                             ( ECC 6.0)
    I am working with assembly orders.  In sales order create - the system creates an assembly order - requirements type = dynamic order.
    If i amend the sales order a few days later - the system reschedules the assembly order - even when the assembly order is started and has status REL = released.  I get error CO061 - start date in past.. as the system first backwards reschedules and then reschedules forwards.
    Question -  any ideas how i can prevent assembly order rescheduling when in sales order change VA02 ? I need the system  to check the production order status and if = REL then prevent the rescheduling.  Putting a change block on the production order does not work as it ultimately breaks the link between sales:assembly order.
    I am thinking i need to use an SD user exit to read the assembly order and prevent order changes if the assembly order is = REL.
    thanks in advance
    Graham.

    Hi Ram
    We are using dynamic link.  My original solution was to set the 'nochange' on release- however if the sales order qty changed - or the dates changed - or indeed any ATP check was performed - the link was sometimes lost - dependant on user keystrokes.  VA02 still calls assembly order change in this scenario - and the user gets the mesage that no change is present - and ATP returns 0 qty.
    What I think i can use is user exit  EXIT_SAPLCOEXT_001 in conjunction with a user status.  I plant to set the status 'block' on release - although configure it to have no action.  In the user exit - called in the interface between sales / assembly order - I plan to check the assembly order for this status and set the error condition if the status is set.  In debug mode - setting the eror manually - this appears to work as the system never calls assembly order change and accepts the assembly order date/qty as 'supply' in the atp check.
    thanks for you assistance.
    regards
    Graham

  • How can we prevent a user from entering a value in Parameter Field?

    how can we prevent a user from entering a value in Parameter Field and Select-options Field?

    make it invisible, make it inactive, make it display only.
    if the field is not there or not to be seen the user WILL have problems inputting data.
    BUT once the field is there you can NOT prevent that the user fills it with data.
    all you can do is on PAI check if the data the user inputted was good or bad, and clear his inputs, but you can NOT prevent him inputting something.

  • Inactive RAM not reclaimed?

    Hi,
    I recently got my 27'' iMac. Today I had a lot of apps opened and noticed something really weird: My iMac became really sluggish even though the apps weren't that CPU intensive and CPU wasn't used that much. I then noticed my system memory readings seemed kind of odd:
    Free: 40MB
    Wired: 480MB
    Active: 2.3GB
    Inactive: 1.14GB
    Swap Used: 1.73GB
    I think the computer became sluggish because the RAM was full. But what I really wonder about: Why does mac os start swapping RAM to the hard drive when there is 1.1GB of inactive RAM? Shouldn't the OS reclaim that RAM first which would be much faster than swapping all the time? It was kind of annoying since I was watching an HD movie and it lagged even though CPU usage was low and there was 1.1GB of inactive, fast RAM the system could have claimed.
    Ideas on this?
    thanks

    Yes.
    That "works"...but it isn't really annoying, and even somehow, is that not "the way" to solve it?
    - I think -
    Since I have 4Gb. RAM, a new updated MBP (using basic aps - mail, ical, safari, address-book, itunes,finder,ms.office, adium and skype, - and I do not use PS, FC or VM's) - it doesn't make much sense (to me) to realize (and I do) that I need to upgrade to 8Gb. in order to have a proper and smooth performance (that it should already be), just because the system 'eats' literally the ram installed.
    And of course, since the RAM upgrade is not what it could be called "cheap", and not a solution - I can't afford it right now at that prices - I can't keep searching and trying to find a workaround to solve this...
    I simply can not understand how I do have page ins/outs and swap use, considering that the inactive memory (usually more than 1Gb. ) is still there, and it's noticeable when the system - sluggish - has to access the hard disk.
    And how after a day, 2 or more...the system starts to become fatter.
    Because it does.
    And how, anyone seems to bother, ask, and complain about it.
    Well, some people did, but mostly the answers to them are mainly that the system is ok, nothing's wrong, and just upgrade or permissions repair.¿?
    Well I'm may be, a "demanding" user, but my expectations are according to my light-user-tasks and the machine used and its expected performance...or may be I have to start restarting my system every day to avoid it. (or do the permissions repair)
    And that there is not response, neither solution still 10.6.4.
    It's like no one seems to see it.
    Just a few. And most users tend to think that there's nothing wrong about it.
    But I do not get it.
    Meanwhile, the only thing I can do is, pray for that one of these to things happens: either next 10.6.x update fix it, or RAM prices decreases... but I can't see other options right now.
    (Thanks, and excuse my english)

  • Free ram to Inactive Ram

    I'm not really sure how to ask this, but here goes. I know that inactive ram is better than free ram, inactive ram actually helps speed up my computer. And I know that free ram isn't really being used by the computer. I see that I usually have anywhere from 80 to 120 mb of free ram. I guess the question, how can I get that free ram to become inactive ram so that my laptop is at full potential? Thanks guys.

    Free RAM hasn't been used by any process recently, while inactive RAM has been used by a process and is being preserved in case the application which previously used it needs it again. You can use up the free RAM by opening additional applications, but if you don't intend to do anything else in those applications, you will not get any speed benefits by doing this.

  • Inactive RAM - Not Returning to Free

    I have come to notice that after launching somewhat memory hungry programs, such as HandBrake (a DVD ripping application), the RAM is slowly activated until there is at least 1 GB Inactive RAM, even though actual active and wired RAM is 1/2 GB at most.
    Though this is to be expected, it seems that RAM continues to move to Inactive until there is only 50 MB of Free RAM left, even though no more RAM is being used for the actually application.
    You would think this wouldn't cause a difference in performance, but all streaming video moves with short blips every half second, and in general the computer begins to lag.
    Yet after I terminate the application, none of the RAM is restored to the Free state, and the lag continues, suggesting that the computer is digging to the actual Hard Drive for memory.
    Does anyone know what is going on, or any pointers on how to avoid this?

    Hi,
    There are some changes to memory garbage collection introduced with Leopard. Of course, there is supposed to be improvement. Here's an article I found:
    http://developer.apple.com/leopard/overview/objectivec2.html
    It could be an older application might not be optimized for best garbage collection strategy, and the default under Leopard might not be as efficient. A tweak and recompile might be needed to specify the best suited garbage collection alogorithm. This is the kind of thing that probably wouldn't show unless an application allocates and deallocates a lot of memory. It sounds like Leopard holds off rebuilding its free list as long as possible, so there's more work for it to do and hence a video stutter.
    I think for something like VLC, the generational garbage collection strategy may get in the way because moderate chunks of memory are getting allocated at a constant rate as rendering takes place. The garbage collector thread of a Cocoa application runs at low priority and the way allocations are taking place make more work when the collection thread has to examine the object graph for long-lived objects to free. I'm not a heavy duty kernel and Cocoa person; please forgive me if I am in error.
    The upshot is that Leopard may be the cause, but not because Leopard is doing something wrong per se.

  • Inactive RAM (yes I know what it does)

    My question is how Inactive RAM is reported once it has been used by the system. Here is what is happening to me. I sometimes there will be a spike in my RAM used and when I look at the activity I will see that there is about 200-250mb of Inactive RAM but my computer will slow to a crawl like it is out of RAM. I understand Inactive RAM is not currently being used and is supposed to be released when needed by other programs but when it is released should it shift to Active RAM? So should I see my Inactive RAM go down and my Active RAM go up? Or does the Inactive RAM just stay the same even though it is being used by the system.

  • Gratuitous kernel panic on my iMac G3 running Tiger. How can I prevent this

    Ok, I know I probably shouldn't have installed Tiger on my G3 iMac so you don't need to remind me. However, it runs pretty good and I hardly ever even see the beachball spinning when I ask it to do something. What I am shocked, shocked by is the ridiculous amount of frequency that I end up with a kernel panic that gives me the 'gray screen' telling me I have to restart my Mac. I have been able to keep this down to a minimum by pointedly only running programs and commands one at a time with a good sized pause in between but even with that I am diappointed with how often it happens. Call me a heretic, but I think it would have killed Apple to stick with their classic OS framework rather than go to UNIX. I would like some tips about things I could do to minimize this occurence above what I already do. It really ***** to have had to reinstall Tiger about 3 or 4 times since I upgraded and have to change up the screen position, dock, desktop, mouse, screen saver, and reinstall all my programs after my iMac has croaked and finally accepted another reload of Tiger.

    I'll ignore the major portion of your post which comes across as a rant and try to stick with the title: "kernel panic on my iMac G3 running Tiger. How can I prevent this?"
    Kernel panics are usually caused by bad or marginal RAM or RAM that isn't seated properly, or by buggy or damaged software or drivers. In the past, problems with marginal RAM for Macs has shown up when people upgraded to new versions of the OS -- which might fit your situation.
    Although your CPU is slow, you have lots of RAM, so Tiger should run OK, if the RAM is not defective. You don't mention how much free space you have on your hard drive. Typically you're going to need at least 5 Gig free to give Tiger breathing room.
    Running a system maintenance utility like Yasu would probably also be beneficial:
    http://jimmitchell.org/projects/yasu/
    What does the hardware test for your Mac say about your system? This might help us determine if there is a hardware cause for the kernel panics.
