Noob needs help upgrading RAM

Dear All,
I have a Macbook 5,1 late 2008. I want to upgrade my RAM to the maximum since I sometimes use VMware Fusion to run windows 7 for school stuff. I know Apple says my Mac is 4GB max but some of these discussions have mentioned its really 6GB maximum. I was looking at this http://www.newegg.com/Product/Product.aspx?Item=N82E16820104165 . It has the right number of pins and low latency. Or do I have to buy the MAC specific computability memory like http://www.newegg.com/Product/Product.aspx?Item=N82E16820134833
Thanks in advance,
Pat

Dear Kappy,
Thanks for getting back to me so fast. Here is the info from my system profiler.
Model Name: MacBook
Model Identifier: MacBook5,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB
Memory: 2 GB
Bus Speed: 1.07 GHz
Do you think the RAM I first linked would work correctly?

  • Noob needs help: Macbook RAM/storage upgrade advice

    Firstly, let me apologize in advance for my ignorance in this subject area!  I'm a complete noob!
    Here goes:
    I have a MacBook 7,1 (MC516LL/A) with all original, factory components, and since I've upgraded to OS X 10.7.5, it's been running incredibly S...L...O...W... which is incredibly annoying to me:P
    Out of the 250GB's of HD storage, I have about 91 free.  From my previous experience with mac notebooks, I know that I am going to need to get some more hard drive space, soon (my last iBook turned to complete crap, once I got down to 20 gigs of available memory).
    I see that I can upgrade the RAM from two, 1GB sticks to two, 4GB sticks.  From the limited research I've done, I'm under the impression that only the boot-up speed will increase slightly (please correct me if any of this is wrong). 
    I've also been reading about Solid State Drives, found some reasonably priced ones on crucial.com, and they look/sound AWESOME!  Aaaaaand the reality is that I really have no idea what I truly need.  I'm a single mom and a college student, so I'm looking for an upgrade option in the $200-300 range, *and* I'm not into graphic design, web design, or anything that requires top of the line equipment. 
    My macbook is practically glued to my hands 24/7, so I just want it to run FASTER, and I need more storage.  I don't know if this info is pertinent or helps, but outside of studying (all done with ebooks and online websites), I like to download a lot of music, watch videos, upload family pictures, browse the interwebz, etc., etc.
    What can I do to improve speed and expand storage capacity?
    Any help is GREATLY appreciated! Thanks!

    Hello! I own a mid-2010 MacBook (a.k.a MacBook 7,1) running OS X 10.8.2 Mountain Lion, which I use for school, and I had the exact same issues with my MacBook, before I upgraded it. I had almost filled up my MacBook's HDD and my computer's RAM was insufficient to perform any of my day-to-day tasks with ease. I upgraded the RAM from two sticks of 1GB (the factory-installed configuration) to one stick of 4GB, and I installed a 1TB HDD in place of the original 250GB HDD (my requirements were slightly different from what yours seem to be). Currently, my MacBook is a lot less laggy than it used to be (even with a HDD that's four times larger in terms of capacity installed), but it still takes a long time to start up and perform certain tasks. Therefore, from my experience, I would recommend that you do the following:
    1. Get two sticks of 2GB (2x2GB) of RAM, not one stick of 4GB (1x4GB). Even though the latter will probably be considerably cheaper than the former, I think it's worth the few extra dollars to get the former because it's much faster than the latter. You shouldn't go for anything more than 4GB of RAM in total, because it'll overload your MacBook. Trust me, that's not something you want to have to deal with!
    2. Get a 500GB or 512GB SSD, not a larger HDD. In hindsight, I don't think I even needed anything close to 1TB. I only purchased my huge HDD because it was on offer, and it was being sold (believe it or not) for less than a 500GB HDD. But if you're looking for speed, an HDD is not the way to go; they're much, much slower than SSDs, even though they're much cheaper.
    You should see an exponential increase in the speed of your MacBook. You might want to try the following websites; they offer high-quality, affordable components and I've known people (including myself) who have used their products before.

  • I need help,,upgraded to ipad2, laptop had to be restored b4 I backed up iPad or saved iTunes library. How do I back up and sync my ipad2 without losing content on my iPad.

    I need help,,upgraded to ipad2, my HP laptop had major issues and had to be restored b4 I could back up and save any content on the hard disc. So i havent backed up my iPad2 or saved my iTunes library.
    How do I back up and sync my ipad2 without losing content on my iPad.???
    I need really simple instructions as I've had a bad run with my laptop the last month.
    I have re-installed iTunes,it currently has no content in it
    all my music, photos etc had been saved to a an external Hardrive (phew)so I'm not concerned about losing them during a sync, but how do I sync my Ipad without losing the applications... The last back up saved was in June when I still had an ipad1
    I tried to back it up last night but kept getting the prompts something to the effect of "iPad can only be synced to 1 iTunes library, syncing will erase all content and replace with content on this iTunes library".  
    Help please,, I've already lost endless hours fixing my PC issues,so I'm not game to attempt this issue without guarantee I won't lose everything,need a simple solution that anyone can follow as my brain has information overload!!! Lol
    Thanks

    This should help you out. I copied this from another discussion a while back. Here is the original discussion link.
    https://discussions.apple.com/message/11527071#11527071
    This is what is in the discussion. It really doesn't get any easier than this.
    1) Without connecting your iPad to your laptop, start iTunes. Click on Edit. Click on Preferences. Click on Devices. Check the box next to "Prevent your iPod etc. from automatically syncing." Click OK.
    2) Now connect your iPad to your laptop and start iTunes.
    3) When iTunes starts, right click on your iPad under Devices in the left column. Select Transfer purchases etc.
    4) After it finishes transferring all your apps to your new laptop, right click on your iPad and select Backup your iPad.
    5) After it finishes backing up your iPad, right click on your iPad and select Restore etc.
    6) After it finishes restoring, left click on your iPad , then click on the Apps tab on top, and check the box next to Sync Apps, then click on Apply below.
    If everything on your iPad looks good after the sync, go back and click on Edit / Preferences / Devices and UN-check the box next to Prevent your iPod etc. The only other thing you may want to check is if your contacts, bookmarks, etc. are syncing correctly now. If not, go to the Info tab after connecting and make sure you indicate which features you want to sync with what sources.

    Adding RAM will help especially for graphics and number crunching applications. You will no longer get the out of memory warnings. Windows 7 is happier with more memory.
    Be advised that there are only two soDIMM slots for memory in a notebook. That means you will have to replace the current memory modules with two  2 GB memory modules to achieve 4 GB of installed memory.
    I recommend only purchasing guaranteed compatible memory modules.
    That way you won't have disappointments ( blue screens or black screens)  after new module installation and attempting to boot into Windows.
    The better memory modules are made by manufacturers such as Kingston (model  KTH-ZD8000B/2G • DDR2-667 / PC2-5300 • 1.8V) 
    As for the cost: You will have to find your own local supplier by searching online .

  • Need help upgrading from iPhoto 2... keep photo comments?

    I currently have iPhoto 2 that originally came with my eMac. I have recently upgraded the operating system to the 10.4.11. I have tons of photos in iPhoto 2. Ultimately, this has slowed down the response time when working in iPhoto.
    I am trying to figure out how the comments that I write for each photo stays with the photo after I back it up to my external hard drive, iBook? Or, how can I keep the comments to the photo when I email the photos?
    After doing some research, it looks like I need to upgrade to a current iPhoto to be able to do this. Is this correct? Will a current iPhoto version keep the comments with that photo when saved or sent elsewhere? What is the best way to upgrade and how do I go about doing this?
    Is there anyway to backup the photos on disc with the comments included? Or, can the comments be printed out to a thumbnail size of each photo for record keeping?
    I hope you can HELP with this "photo comments" dilemma... Thanks.

    Did you try repairing permissions yet? Just because you have a fresh install of Mac OS X doesn't mean everything is as it should be. And you may not know that the mail format changed from 10.4 to 10.5, so you should try rebuilding your Mail index like this:
    1. Quit Mail if it's running.
    2. Go to ~/Library/Mail and delete the Envelope Index file(s).
    3. Restart Mail, wait for it to import your existing messages, then check to see if you have access to your older mail from 10.4.

  • Need Help Upgrading Old Mac

    I have a macbook pro 15.4 Inch purchased in 2007 *The first intel based mac i believe- But im having trouble upgrading- I tried to upgrade to Snow leopard 10.6.8 (im on 10.5.4) now and i need to upgrade desperatley to run programs i use, The body of the computer (keyboard is shot so i use an external keyboard) when i downloaded different DMGS of snowleopard-i cant get any of them to work and do a DMG instal as you normal would. I tried my original (INSTALL Disks that the my computer came with to an archive install- but the drive kicks the dvds out once i hit option - to try to boot the disk when the computer starts up (the computer's body is ****** but it works ok- it has to be plugged in all the time) but i dont know how i can update my system i  even tried snow leopard 911 - but even when i put it on a 4GB hard drive and tried to boot from my little thumb drive (by pushing C on start up) it just started up regularly. I was gonna take smewhere to have an archive install but it would cost me 120.00 per the visit (since this computer isnt worth much and i just need it to be able to run until i get a new one in 2013) - Ive done everything tested the PRAM , done a "C" and even option boots it to EFI mode, which i dont want ive downloaded mutliple DMGS of snow leopard and they dont work , i just want to upgrade!! - Can you help!! if you have ANY solutions
    <Email Edited By Host>

    I'm not sure where you're getting dmg files of Snow Leopard - it was only ever released on disc. You can order it directly from the Apple Store on disc here - http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard. If your optical drive isn't working, you'll just have to get a fairly inexpensive external optical drive to install the upgrade.
    It really sounds as if your machine is shot. I had a 2006 model (which was actually the first Intel MBP) and it's still working. But I took care of it. Sounds as if you've been a little rough on yours.
    I'm not certain that the SL update is going to do you any good - but it's worth a try, I guess.

    You can't use DDR2 ram with that board. You need DDR1 PC3200 ram. Best thing to do is sell the ram you currently have and get a new dual channel kit as your slots are already full and further mixing will lead to problems.
    Hi thanks for replying.
    I don't intend to mix the existing rams that I have with a new replace rams. I will just install 2 x 1GB rams. So I need to know if my motherboard will be able to use 1 GB DDR2 533mhz or DDR2 667Mhz rams before I go and buy.
    Really can't use DDR2 rams?

  • Need help with ram on bootcamp

    hey guys i need help with getting more ram on the pc side of bootcamp.
    it says i have 1.99 of ram on the pc side
    then on the mac i got this
    Model Name: Mac Pro
    Model Identifier: MacPro1,1
    Processor Name: Dual-Core Intel Xeon
    Processor Speed: 2 GHz
    Number Of Processors: 2
    Total Number Of Cores: 4
    L2 Cache (per processor): 4 MB
    Memory: 4 GB
    wanting to know how to get more ram over to boot camp

    Rodney:
    You cannot physically or via software add/move RAM from OSx side to Windows side. This is because you run Leopard and Windows separately and therefore when one is running the other is not active. The only thing that controls how much RAM Windows sees/uses is determined by the type of Windows you have installed (32BIT or 64BIT). Please do not confuse that with Gigabytes of RAM or disk space.
    32BIT Windows has a maximum limit of 3GB of RAM (it often uses only around 2GB of RAM when it is sharing the system RAM with your video card. I believe this is the case with you.
    64BIT Windows will be able to sees/use all of your 4GB of RAM.
    Leopard sees/uses all of your 4GB of RAM.
    If you have installed Windows XPSP2 and it is working properly on your boot camp partition then I can assure you that it is the 32BIT version.
    FYI - The only time that one can select/decide how much RAM Leopard uses and how much RAM Windows uses is when one is running Windows as a Virtual Machine under software such as Fusion or Parallels. I have assumed that you are running windows on a boot camp partition (from your posts) and therefore this does not apply to you.

  • [Athlon64] Noob needs help optimizing new system

    Sorry to post yet another thread, but I've been lurking for the past few days and I only get bits and pieces of what I need. I'm pretty clueless about this stuff as it's my first home-built system
    See my sig for system info...
    I'm needing help with bios settings. The pertinent stuff (I think - hopefully I got it all down):
    CELL MENU

    DDR Memory Freq: 100.0 MHz
    High performance mode: Manual

    ADVANCED CHIPSET FEATURES
    AGP Mode: Auto (this is "greyed out")
    AGP Fast write: Enabled
    AGP Aperture size: 128
    VLink 8X supported: Enabled
    My questions mainly concern memory. I bought all this stuff at the Tiger Direct outlet store in Naperville, Illinois. I had intended to buy the K8T Neo-FSR (754 pin), but they were supposedly out of the 754 pin 3400+, and this board/CPU combo had a $100 rebate. Yeah, it's one of those deals with the odd 939 pin 3400+ that everyone has been talking about.
    In any case, I already had the Corsair CMX512-3200C2PT picked out, as Corsair said it was compatible with the board. I wasn't aware of the MSI compitibility chart until I came here later that night. I STILL can't find that chart off of the MSI web site.
    Anyway, I got it all hooked up and got the standard 4 red LEDs. Not knowing what to do, I took it back to Tiger Direct and the tech played around with it until he stuck an el-cheapo stick (Corsair VS512MB400) in there and it worked. But it only works in slot 2. So here I am.
    I started to run memtest86, but it took too long to run and I aborted it for now. For what it's worth, it said the RAM CAS value is 2.5-2-2-5. I don't know what the hell that means, but I know it's important.
    My questions:
    1. I assume I need manually to set my memory clock value to DDR400?
    2. Now that I can get the thing to post, is there any chance I could get the "good" Corsair memory to work by setting the correct latency/CAS values? Again, I don't know what I'm talking about, so forgive my ignorance. What I'm wondering is if I can set everything to what Corsair recommends while I have the cheap memory in there and then replace it with the good stuff?
    3. With this board, am I better off with double-sided or single-sided sticks? As I said, I went into the store intending to buy the Neo 754-pin board, but they were out of the Athlon 3400+ in 754 and only had the 939 pin.
    4. Anything else in my bios settings that stand out and need to be addressed? I want to make sure everything is optimized.
    EDIT: I almost forgot: My CPU temp is runing around 42-49 degrees. Am I in the danger zone? I just bought a generic cooler for now and intend to get a Thermalright XP-120, but I can't find it locally, so it will have to wait.
    AND FINALLY...
    I don't know if this is related to anything above, but I have been having a hell of a time getting the 6600GT to run DirectX9+ games. The latest drivers for Windows 98SE was 66.94. Yes, XP will be installed soon, but for now... It was failing on dxdiag test for Direct3d 9 and also the third DirectDraw test. I was about to give up and take it back when I discovered that a new beta driver came out today (71.84). I installed it and it passed all of the dxdiag tests. I thought I was in hawg-heaven, but when I run Call of Duty (the only DX9 game I have besides HL2), it slows to an absolute clawl. The level starts out somewhat normal at first, but quickly slows down to the point that performance can only be measured in seconds per frame! All of the patches 1.5 and 1.51 for UO have been installed, but that shouldn't make a bit of difference.
    If I don't get my CoD fix soon I'm gonna reinstall that Geforce3.
    Thanks much and sorry again for such a long post.

    Thanks everyone for the recent replies, but I started this thread almost a month ago (March 3rd), and much has changed since then.
    New PSU (see sig).
    Replaced the PNY Geforce6600GT with a eVGA 6800
    Added another stick of the Corsair Value Select 512 RAM. I didn't even bother trying to get the "primo" CMX stick to work. I just returned it.
    Went from Windows 98SE to XP Home.
    The PSU did nothing for me at all, but I suppose it's better to have some headroom in the amperage.
    The biggest performance booster was the additional 512MB of RAM. It wouldn't have done me any good in 98SE, but I was shocked at how much it helps XP. Quitting a game is almost instant now, where before it would take a good two minutes or so for XP to recover itself.
    As for games running slow, the 6800 fixed it right up. CoD absolutely screams now, as does everything else I've thrown at it (HL2, Doom 3, Far Cry). I think the 6600GT was just bad or there is a serious driver problem with the 6600GT's. Went from 3DMark03 score of around 5000 (when it didn't crash) to above 9000 now. And this was all before adding the additional RAM.
    Oh yeah, I bought a 74GB Raptor. No RAID for now though. So far I'm not real impressed with the performance. I'm running off of the VIA controller, since my board doesn't have the Promise controller. I don't see much improvement in loading times as compared to the 40GB 7200rpm Maxtor I have running on IDE1. The only time it beats the pants off the Maxtor is defragging. But there's only so much entertainment value in that.  The Sandra "file system benchmark" gave me 57 MB/s, which seems pathetic, but I've read some posts here where others are getting an identical rate.
    And I'm not too happy to discover, too late, that my overclocking capabilities are severely limited while using SATA.
    I do have one more question for now:
    When I installed the second 512MB stick, I originally had both sticks in slot 1 and 2. I ran Sandra's memory bandwidth benchmark and got a much lower score than with the single stick (around 3500 MB/s). WHen I had the sticks in 1 and 3, it jumped up to close to 6000 MB/s. Why is that? Just curious.

  • Noob Needs Help! Please Please Please Help!

    MD doing reserach on Genetic Mutations, I really need help on this, I have never used PL/SQL. Can somebody help me with this?
    I have a view made of mulitple table that has following columns: diagnosis, patient_id, kindred_id, column_d, colum_e.... column_p where each distinct combination of column_d to column_p means one specific mutation. I want to group patients who have same mutation to find out the following:
    for each mutation(unique column d through column p), I want to find out how many families have diagnosis 1, diagnosis 2, diagnosis 3...
    The rule is the program will look at kindre_id first, to see if this person's kindre_id has been looked at. If
    so, jump it/ignore it. If this kindred_id has never been looked at, treat it as a unique family. Diagnosis count for that diagnosis will then increase by 1. Sounds easy, but I don't know how to write that for loop that will do for each unique (column d, column c, ... column p) do the following... Does such a thing exist?

    Hi,
    SELECT     diagnosis
    ,     COUNT (DISTINCT kindred_id)     AS family_cnt
    ,     column_d

             3          2 abc        bca        acbwhich is the data you want, but not in the format you want. You want to pivot the family_cnt column from the three rows into three columns in one row. For general information about how to this, search for "pivot" on this or similar sites.
    One solution is:
    SELECT     COUNT (DISTINCT CASE WHEN diagnosis = 1 THEN kindred_id END)     AS diagnosis_1
    ,     COUNT (DISTINCT CASE WHEN diagnosis = 2 THEN kindred_id END)     AS diagnosis_2
    ,     COUNT (DISTINCT CASE WHEN diagnosis = 3 THEN kindred_id END)     AS diagnosis_3
    ,     column_d
    ,     column_e
    ,     column_f
    FROM     table_x
    GROUP BY     column_d
    ,          column_e
    ,          column_f
    ;     which produces the following output:
    DIAGNOSIS_1 DIAGNOSIS_2 DIAGNOSIS_3 COLUMN_D   COLUMN_E   COLUMN_F
              2           2           2 abc        bca        acbThis technique assumes that you know exactly how many different diagnoses there are and what the distinct values of the diagnosis column are. (I.e., in this example, I knew that that there were three diagnosie and that their values were 1, 2 and 3. I used that information to write three COUNT expressions, with values 1, 2 and 3 hard-coded into them.)
    So, what can you do if you do not know the diagnosis values? The columns have to be hard-coded into the query, so how can you possiblly write something today that will have all the values that are in the table next month? You can't, but you can write something today that you can run (unchanged) next month which will write such a query. In other words, you can do dynamic SQL, where you run a preliminary query to get the different diagnosis values, write an appropriate query similar to the one above, and then run that newly-created query. The PL/SQL command "EXECUTE IMMEDIATE" can help with this.
    The code above works in all versions of Oracle. In Oracle 11, there is a more straigtforward way of specifyng PIVOT in a SELECT statement.

  • Need help upgrading software on imac mid 2010, running OS X 10.6.8

    I need to upgrade my software from OS X 10.6.8 but not sure where to begin.  Do I have to purchase lion, mountain lion, leopard, snow leopard to get to maverick???

    1. Yes, it is.
    2. You can either use Time Machine or a product such as the Disk Utility, Carbon Copy Cloner, or SuperDuper to create a bootable clone. Create the backup on an external drive in case the internal one fails.

  • Uber Noob Needs Help Creating website!

    I need help creating my webpage: It has a textbox on it were
    the user enters a URL and it then redirects the end user to that
    URL when they press the GO Button. It also has a check box saying
    "Hide my IP", If the end user clicks this box and then clicks go
    they will be directed to the website they stateted in the Textbox
    but this time it shall mask there IP Address so they can bypass
    proxys and surf anonomosly. Please can someone give me some HTML
    code i could use for this site or a Link to a website that can give
    me the code.

    I assume the application is connecting to Oracle using an application ID/password. If so, check to see if that user has a private synonyn to the table. If so drop it since you have a public synonym.
    Verify that the public synonym is in fact correct. Drop and recreate the public synonym if you cannot select against the synonym name using an ID that can perform select * from inhouse.icltm where rownum = 1. That is if this other user cannot issue select * from icltm where rownum = 1 without an error.
    Check that the application ID has the necessary object privileges on the table.
    Queries you need
    select * from dba_synonyms
    where table_owner = 'INHOUSE'
    and table_name = 'ICLTM'
    You may find both public and private synonms. Either fix or delete. (Some may reference someelses.icltm table if one exists)
    select * from dba_tab_privs
    where table_name = 'ICLTM'
    and owner = 'INHOUSE'
    Note - it is possible to create mixed case or lower case object names in Oracle by using double quotes around the name. Do not do this, but do look to see that this was not done.
    You could also query dba_objects for all object types that have the object_name = 'ICLTM'
