Quick ram question

im looking at this for buying ram:
http://eshop.macsales.com/shop/memory/Mac-Pro-Memory
i have 1 gig in my mac pro right now, 2- 512's
I'm confused on what I should get. It seems like what I figured would be more expensive is less and vice versa.
i can get 2 gigs of 1 gig sticks for 239.99
i can get 2 gigs of 4 512 sticks for 314.95
i can get 2 gigs of (different) 1 gig sticks for 229.99
please help! what do I want?

DIMMs have to match exactly within a pair. However, between pairs you don't have to match anything. Also, there's absolutely nothing wrong with 3GB RAM in this configuration and will be more efficient than a 6 x 512MB configuration.

  • Quick RAM question... 8GB on x100e

    i know the x120 accepts more than 4GB of ram, but is there any reason a x100e will not take 8GB of ram?
    ill be running win7 x64. thanks.

    Hello,
    It's not a Lenovo-supported configuration, but I was able to install 2×4GB DDR2 SO-DIMMs in my X100e and access most of it (I believe some of it was reserved for use by the video card).

  • Hi all .hope all is well ..A quick trim question

    Hi all
    Hope all is well ......
    I have a quick trim question I want to remove part of a string and I am finding it difficult to achieve what I need
    I set the this.setTitle(); with this
    String TitleName = "Epod Order For:    " + dlg.ShortFileName() +"    " + "Read Only";
        dlg.ShortFileName();
        this.setTitle(TitleName);
        setFieldsEditable(false);
    [/code]
    Now I what to use a jbutton to remove the read only part of the string. This is what I have so far
    [code]
      void EditjButton_actionPerformed(ActionEvent e) {
        String trim = this.getTitle();
          int stn;
          if ((stn = trim.lastIndexOf(' ')) != -2)
            trim = trim.substring(stn);
        this.setTitle(trim);
    [/code]
    Please can some one show me or tell me what I need to do. I am at a lose                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            

    there's several solutions:
    // 1 :
    //you do it twice because there's a space between "read" and "only"
    int stn;
    if ((stn = trim.lastIndexOf(' ')) != -1){
        trim = trim.substring(0,stn);
    if ((stn = trim.lastIndexOf(' ')) != -1){
          trim = trim.substring(0,stn);
    //2 :
    //if the string to remove is always "Read Only":
    if ((stn = trim.toUpperCase().lastIndexOf("READ ONLY")) != -1){
       trim = trim.substring(0,stn);
    //3: use StringTokenizer:
    StringTokenizer st=new StringTokenizer(trim," ");
        String result="";
        int count=st.countTokens();
        for(int i=0;i<count-2;i++){
          result+=st.nextToken()+" ";
        trim=result.trim();//remove the last spaceyou may find other solutions too...
    perhaps solution 2 is better, because you can put it in a separate method and remove the string you want to...
    somthing like:
    public String removeEnd(String str, String toRemove){
      int n;
      String result=str;
      if ((n = str.toUpperCase().lastIndexOf(toRemove.toUpperCase())) != -1){
       result= str.substring(0,stn);
      return result;
    }i haven't tried this method , but it may work...

  • VERY SPECIFIC RAM QUESTION (not answered in prior topics)

    I have a very specific RAM question. I've been pouring through the discussions and I see TONS of stuff about the proper way to upgrade RAM. I've done that before without incident, but here is my dilemma:
    I'm using the 3.0Ghz, 8-core, MP currently with 8GB of the 667Mhz RAM (8x1GB). The memory is all matched from OWC and I have had no problems.
    I just bought 16GB of new RAM from OWC (4x4GB).
    I'm going to remove all 8 of the current 1GB DIMM's, and place two of the 4GB DIMM's in slots 1 & 2 on riser A, and two of the 4GB DIMM's in slots 1 & 2 on riser B. That will give me 16GB's in matched pairs on slots 1 & 2 of both riser A and B.
    My question is this: Should I install two of my old 1GB DIMM's in slots 3/4 of riser A, and two of the old 1GB DIMM's in slots 3/4 of riser B (for a total of 20GB's)?
    I've read that having all 8 slots filled = better performance but I'm not sure the mix of 4GB DIMM's and 1GB DIMM's.
    Any Thoughts?
    Thanks So Much,
    Tom

    Optimally you want matched quads in each Riser. However, Bare Feats did some memory benchmarks that you might wish to read regarding memory performance versus different configurations. As for proper installation see the following:

  • Quick script question

    Hi all,
    Could anyone advise me if i can add anything within - header('Location: http://www.mysite.co.uk/thankyou.html'); in the script below so as the page
    re- directs back to the main index page after a few seconds ?
    Thankyou for any help.

    Mr powers gave me that script so im rather confused at this point in time
    I don't think I "gave" you that script. I might have corrected a problem with it, but I certainly didn't write the original script.
    What you're using is far from perfect, but to suggest it would lay you open to MySQL injection attacks is ludicrous. For you to be prone to MySQL injection, you would need to be entering the data into a MySQL database, not sending it by email.
    There is a malicious attack known as email header injection, which is a serious problem with many PHP email processing scripts. However, to be prone to email header injection, you would need to use the fourth argument of mail() to insert form data into the email headers. Since your fourth argument is null, that danger doesn't exist.
    One thing that might be worth doing is checking that the email address doesn't contain a lot of illegal characters, because that's a common feature of header injection attacks. This is how I would tidy up your script:
    <?php
    $suspect = '/Content-Type:|Bcc:|Cc:/i';
    // send the message only if the E-mail field looks clean
    if (preg_match($suspect, $_POST['E-mail'])) {
      header('Location: http://www.example.com/sorry.html');
      exit;
    } else {
      $to = '[email protected]';
      $subject = 'Feedback form results';
      // prepare the message body
      $message = 'Name: ' . $_POST['Name'] . "\n";
      $message .= 'E-mail: ' . $_POST['E-mail'] . "\n";
      $message .= 'Phone: ' . $_POST['Phone'] . "\n";
      $message .= 'Message: ' . $_POST['Message'];
      // send the email
      mail($to, $subject, $message);
      header('Location: http://www.example.com/thankyou.html');
      exit;
    ?>
    Create a new page called sorry.html, with a message along the lines of "Sorry, there was an error sending your message". Don't put anything about illegal attacks. Just be neutral.
    By the way, when posting questions here, don't use meaningless subject lines, such as "Quick script question". If you're posting here, it's almost certain to be a question about a script. It doesn't matter whether it's quick. Use the subject line to tell people what it's about.

  • HP dv9629ca Laptop (Ram Question)

    Here is a RAM question. The Laptop had 2 one Gigabyte SO-DIMMs with them both installed the PC would not boot. the lights would come on but the screen remained black. I thought it was a RAM problem since when I would only put in a single stick of RAM the computer Booted no problem. I figured the one ram was BAD. Yet when i bought a 2GB SO-DIMM and added it to the 1GB already inside the computer wouldn't boot just like before. so I removed both rams and Put the 2GB stick in where the other was working and It shows 2GB now. I Know the Laptop maxes out at 4GB of RAM with a 64bit version of Windows installed. Is it possible to find a 4GB SO-DIMM and put it into the Slot that works or will it only accept a maximum of 2GB per Slot?
    Laptop Details
    AT newegg.ca they have a Single SO-DIMM that is 4GB the Laptop Max is 4GB. Not sure if it would read 4GB coming from a single SO-DIMM

    Here are the specs for your HP Pavilion dv9629ca Notebook Computer and here is the HP Pavilion dv9500, dv9600, and dv9700 Entertainment PC - Maintenance and Service Guide for your computer. Both pieces of information indicate that 4GB (2 X 2GB) is the maximum. 2GB is the largest size supported in each slot.
    You may wish to clean the slots or reseat the memory... you may also want to inspect the slots for debris or bent contacts.

  • Quick RAM upgrade question.

    Just got new 3 GHz Mac Pro that came with 2GB of RAM in 4 x 512 configuration.
    I just took delivery of an extra 2GB of RAM from Crucial in the post. This new ram came as 2 x 1GB sticks.
    Can anyone advice which board I insert them into, the same one as where the 4 x 512 sticks are, or the empty board?
    Cheers.

    Yes and no. What you should do is to actually try it to see what gives better performance.
    The reason it's yes is that the Mac Pro, for whatever reason, does favour Riser A in some way. So, with the standard 1GB RAM you will get better performance with it being in Riser A than Riser B. Go figure! This is why Apple says to fill them in the order they do.
    The problem is though is that Apple does not presume as to the size of the DIMMs you're filling your slots with. The RAM in the Mac Pro performs best when there is balance. Where there is an inbalance you favour Riser A. So, from this you put your better 2GB RAM configuration into Riser A which is the 2 x 1GB DIMMs (lower latency when using the full 2GB as slots 3/4 aren't used). This goes against Apple's fill order.
    So what do you do. Well… try it both ways and just do what performs best. In actual fact the best thing to do is to buy 1 or 2 more GB (prefereably 2 x 1GB) to fill all 8 slots. It's why it is recommended that you either have 4 or 8 DIMMs so these "conflicts" don't come into play like they do here.

    I have done some research on line and I have the following questions:
    RAM
    1) What is the maximum RAM my mac can take without causing problems. Apple mentions that the maximum RAM is 4GB (2 x 2GB) but I have seen mentioned in threats that up to 8GB have been installed.
    2) The RAM quoted in the specs from apple is DDR3 PC3-8500/DDR3-1066. Could I use a faster chip such as DDR3 PC3-10600/DDR3-1333 or is this upgrade not advisable.
    Hard Drive
    1) Is there a limit to the maximum capacity re hard drive. The maximum apple used to offer this model was 320GB. I would ideally would like to go up to 500GB to 1TB.
    2) The specs of my existing drive are: 160GB 5400-rpm Serial ATA hard disk drive. Could I get a faster disk, say 7200 rpm to increase performance and will this have any significant impact on battery life and heat?
    Further more any recommendations in terms of any of the above welcome.
    A lot of information but I wanted to offer all the info needed for meaningful advice.
    Thanks in advance.

    Hi Christos77,
    I also have a late 2008 13 inch unibody MacBook - mine has the 2.4GHz Intel Core 2 Duo processor and a 250GB Toshiba hard drive.  At the beginning of January I upgraded my RAM from the original 2GB to 8GB from OWC and it made an enormous difference to the functionality of my machine.  In fact, it turned it from being almost unusable to working in a reasonable way. 
    The recent death of my Time Capsule has prompted me to re-think my setup and, basically, what I need is a drive with greater capacity than my original Toshiba 250GB that the MacBook shipped with.  I'm currently working with only 11.65GB of Available disk space so I need to do something pretty quickly.
    I've been researching over the past couple of days and decided that my need for storage is greater than my need for speed so I've decided to replace my existing HDD with a new HDD instead of going down the OWC 'Data Doubler' route. 
    I, too, thought that the 750GB WD Scorpio Black 7200 rpm drive would be the best (and most cost-effective) solution but I've read reports from some users that it was either noisy and/or hot.  However, none of these comments came from users with a late 2008 MacBook.
    I would be very grateful if you could confirm that, after almost twelve months, you're still happy with your WD Scorpio Black drive in your late 2008 MacBook?
    One last question ... when you now check the Serial ATA details in the  System  Report, does it still show your new WD hard drive having a 'Negotiated Link Speed' of 1.5 GB or is it now SATA 2 (i.e. 3GB)?
    Many thanks for your help.
    Cheers
    Tricia
    BTW I've been running OS X 10.7.x on my system since it came out - no problems at all with it - am thinking of upgrading to 10.8 because I've read that it takes a little less space and is more efficient in memory management - but will have to check a few more things first before I decide to do that!

  • Urgent help with quick translation questions

    Hello,
    I am somewhat new to Java. I have a translation to hand in in a few hours (French to English). Argh! I have questions on how I worded some parts of the translation (and also if I understood it right). Could you, great developers, please take a look and see if what I wrote makes sense? I've put *** around the words I wasn't sure about. If it sounds strange or is just plain wrong, please let know. I also separated two terms with a slash, when I was in doubt of which one was the best.
    Many thanks in advance.
    1) Tips- Always ***derive*** the exceptions java.lang.Exception and java.lang.RuntimeException.
    Since these exceptions have an excessively broad meaning, ***the calling layers will not know how to
    distinguish the message sent from the other exceptions that may also be passed to them.***
    2) The use of the finally block does not require a catch block. Therefore, exceptions may be passed back to the
    calling layers, while effectively freeing resources ***attributed*** locally
    3) TIPS- Declare the order for SQL ***statements/elements*** in the constant declaration section (private static final).
    Although this recommendation slightly hinders reading, it can have a significant impact on performance. In fact, since
    the layers of access to data are ***low level access***, their optimization may be readily felt from the user’s
    perspective.
    4) Use “inlining.”
    Inlining is a technique used by the Java compiler. Whenever possible, during compilation, the compiler
    copies the body of a method in place of its call, rather than executing a ***memory jump to the method***.
    In the example below, the "inline" code will run twice as fast as the ***method call***
    5)tips - ***Reset the references to large objects such as arrays to null.***
    Null in Java represents a reference which has not been ***set/established.*** After using a variable with a
    large size, it must be ***reassigned a null value.*** This allows the garbage collector to quickly ***recycle the
    memory allocated*** for the variable
    6) TIPS Limit the indexed access to arrays.
    Access to an array element is costly in terms of performance because it is necessary to invoke a verification
    that ***the index was not exceeded.***
    7) tips- Avoid the use of the “Double-Checked Locking” mechanism.
    This code does not always work in a multi-threaded environment. The run-time behavior ***even depends on
    compilers.*** Thus, use the following ***singleton implementation:***
    8) Presumably, this implementation is less efficient than the previous one, since it seems to perform ***a prior
    initialization (as opposed to an initialization on demand)***. In fact, at runtime, the initialization block of a
    (static) class is called when the keyword MonSingleton appears, whether there is a call to getInstance() or
    not. However, since ***this is a singleton***, any occurrence of the keyword will be immediately followed by a
    call to getInstance(). ***Prior or on demand initializations*** are therefore equivalent.
    If, however, a more complex initialization must take place during the actual call to getInstance, ***a standard
    synchronization mechanism may be implemented, subsequently:***
    9) Use the min and max values defined in the java.lang package classes that encapsulate the
    primitive numeric types.
    To compare an attribute or variable of primitive type integer or real (byte, short, int, long, float or double) to
    ***an extreme value of this type***, use the predefined constants and not the values themselves.
    Vera

    1) Tips- Always ***derive*** the exceptions java.lang.Exception and java.lang.RuntimeException.***inherit from***
    ***the calling layers will not know how to
    distinguish the message sent from the other exceptions that may also be passed to them.***That's OK.
    while effectively freeing resources ***attributed*** locally***allocated*** locally.
    3) TIPS- Declare the order for SQL ***statements/elements*** in the constant declaration section (private static final).***statements***, but go back to the author. There is no such thing as a 'constant declaration section' in Java.
    Although this recommendation slightly hinders reading, it can have a significant impact on performance. In fact, since
    the layers of access to data are ***low level access***, their optimization may be readily felt from the user’s
    perspective.Again refer to the author. This isn't true. It will make hardly any difference to the performance. It is more important from a style perspective.
    4) Use “inlining.”
    Inlining is a technique used by the Java compiler. Whenever possible, during compilation, the compiler
    copies the body of a method in place of its call, rather than executing a ***memory jump to the method***.
    In the example below, the "inline" code will run twice as fast as the ***method call***Refer to the author. This entire paragraph is completely untrue. There is no such thing as 'inlining' in Java, or rather there is no way to obey the instruction given to 'use it'. The compiler will or won't inline of its own accord, nothing you can do about it.
    5)tips - ***Reset the references to large objects such as arrays to null.***Correct, but refer to the author. This is generally considered bad practice, not good.
    Null in Java represents a reference which has not been ***set/established.******Initialized***
    After using a variable with a
    large size, it must be ***reassigned a null value.*** This allows the garbage collector to quickly ***recycle the
    memory allocated*** for the variableAgain refer author. Correct scoping of variables is a much better solution than this.
    ***the index was not exceeded.******the index was not out of range***
    The run-time behavior ***even depends on compilers.***Probably a correct translation but the statement is incorrect. Refer to the author. It does not depend on the compiler. It depends on the version of the JVM specification that is being adhered to by the implementation.
    Thus, use the following ***singleton implementation:***Correct.
    it seems to perform ***a prior initialization (as opposed to an initialization on demand)***.I would change 'prior' to 'automatic pre-'.
    ***this is a singleton***That's OK.
    ***Prior or on demand initializations***Change 'prior' to 'automatic'.
    ***a standard
    synchronization mechanism may be implemented, subsequently:***I think this is nonsense. I would need to see the entire paragraph.
    ***an extreme value of this type******this type's minimum or maximum values***
    I would say your author is more in need of a technical reviewer than a translator at this stage. There are far too serious technical errors in this short sample for comfort. The text isn't publishable as is.

    1. Add an event listener to the window.nativeWindow object, listening for the NativeWindowDisplayStateEvent.DISPLAY_STATE_CHANGING  or DISPLAY_STATE_CHANGE events.
    2. Add an event listener to your SystemTrayIcon object. You can listen for click, mouseUp or mouseDown events, but doubleClick events are not dispatched by this object.

  • MSI 915p Thoughts & ram questions

    Hi All,
             I'm thinking of buying one of  MSI 915P neo2 Platinum motherboards, but i have a couple of questions. Firstly i'm having dificulty finding reviews for this mobo, so i've come here to see what you think of it (unbiased of course). Secondly i'm confused over what type of RAM it supports, some parts sellers list PC4200 others PC4300, i'm even seeing the newer PC5300 being mentioned. And finally what the difference between PC4200 & PC4300.
    Thanks inadvance
    Ian P.

  • Quick REGEXP_LIKE Question

    Hi everyone,
    Had a very quick question: so I need to retrieve all records that have values in this format "type:123;target_id:456". Note that the numeric value can be 1-6 digits long for either type or target_id.
    Can someone please help me with the regexp_like-ing this?
    Thank you,

  • "AFX CS3 - RAM Question"

    hi,
    i have a question about the usage of RAM in After Effects CS3.
    If i start AFX it says "using 5% of 3GB" - but i got 5GB...the same number appears while i'm previewing my comp.
    System: 5GB RAM - 2x Dual Core 2,6 Ghz MAC / Tiger
    Thx.

    See the
    "Render multiple frames simultaneously" section of After Effects CS3 Help on the Web for the "how".
    See the other sections in
    "Memory, storage, and performance" for the gory details of how After Effects uses RAM and such.

  • Mac Pro 8 Core (2008) Hard Drive & Ram questions

    Hi there,
    I recently purchased a Mac Pro 8 Core 2008 Model with 2Gb ram and 320Gb Hard Drive (Got a great deal on it... paid $1,500.00 for it!!). I bought this computer exclusively for audio production work. I know I can upgrade up to 32GB of ram if I wanted to however, I have heard that the system won't recognize 32GB ram when running 32bit OS & Applications. I use Ableton Live 8.2 (32bit capable) and Logic Studio 9 (32bit & 64bit capable).. what is the highest amount of ram I should upgrade to without overkilling it? In other words... what is the highest amount of ram I can upgrade to that I will actually notice the difference and that the system will actually use @ 32bit?
    Second question is regarding hard drives... I need at least 320GB for OS and core applications and at least 1 TB for storage... what is the most efficient, fastest and least expensive to upgrade the storage on this machine?
    I really appreciate your comments on this one.

    Someone with Mac Pro, but on OS X 10.6 Install forum, like some, has full suites of CS5, FCP and others, and had run out of space literally on 150GB boot drive.
    Apps like iDVD tech note recommended the boot drive have 24GB of free space (unfragmented for best burn performance) to burn dual layer.
    X-Plane can go anywhere but uses almost 60GB for full world support.
    My rule of thumb is 50% free on boot drive to avoid fragmenting free space such that it causes problems and there is always good performance overall as well as for read/writes.
    To say someone doesn't need xyz when maybe they rre right, and to argue with their own math?
    OS X does not support TRIM or I'd see if you can go with 120GB SSD. One way to slim down boot drive of course, maybe you have, maybe not,
    Move all the data and media files possible off the boot drive can save 100GB and improve I/O at the same time.
    Move the entire home account folder (the above leaves a smaller 1GB home library only on boot drive) which really isn't totally necessary but nice for some.
    WD Black Caviar 2TB $170 is fast and nice or $89 for 1TB (if you think you need A, then get 2 x as much storage).
    2008s don't use 8GB DIMMs and 32GB is as far as they go.
    ATI 5770/5870 or even Quadro 4000 graphics
    did it come with a 4870? or 8800GT?
