MacBook Pro 16GB RAM 1600Mhz

Hi, I have a 13" late 2011 @  2,4GHz i5 and I have bought 16GB RAM @1600Mhz.
I was wonderring if the 1600MHz RAM would work because I've seen people with it working just fine. Now I'm asking this because if I just spend 150 bucks for nothing I'll be p*ssed! And don't forget my MBP is a 13 inch not a 15!!
Thanks,
Thomas

There are 2 different voltage for DDR3 now on Macbooks.
DDR3 (L) for 2012 Macbooks 1600MHz 1.3 - 1.35 Volts.
DDR3 for 2011 Macbooks 1333Mhz 1.5 Volts.
If you've purchased the 1600MHz 1.3 - 1.35Volts and are using it in your 2011 Macbook, the chances of it working are close to none.
If however, you bought the 1.5 volt version of the 1600MHz, it might or might not work with your Macbook, some people might have had success on using them in their Macbook.  But that doesn't mean that it would work with your Macbook.  Unless you bought the same brand and model as the others who had them working in theirs.
In any event, why not just return it and get the right one?  Most resellers might not accept returns but I'm sure they'll do an exchange since you'be got the wrong RAM.

  • Macbook Pro 16gb ram upgradability

    I'm looking into buying a Macbook pro and was planning on buying the non-retina display version. This laptop will primarily be used for school work, iTunes, video streaming, Photoshop, lightroom, aperture, and whatnot. Now i plan on buying the 2.6gh version, but Im wondering if the 8gb of ram it comes with is enough. I also heard somewhere that it would be recognized and wouldn't make a difference if i upgraded it to 16gb.
    I would've liked to go with the new retina display model, but i can only afford the lower entrance model with the 2.3 processor, and i'm not sure if this would work for my needs.

    My 2011 MBP can take 16 GB RAM.  macsales.com sells the 16 GB kit for $160 currently.  Apple tests against the more commonly available RAM types when publishing hardware limits, so only reports 8 GB as a maximum.
    8 GB RAM is abut $50 through macsales.com, so buy the default 4 GB regardless of where you decide to go.

  • Problem on Macbook Pro (16GB RAM, i7) with large video files

    Hallo,
    I have a recurring problem working with Premiere Pro CS6 on a new Macbook. THe Macbook has16GM RAM, i7 processor and I have the video files on my internal disc. THere is enaough space on the disk, aprox 250 GB free.
    I have a Canon Legria HF28. After loading the videos from the camara it's .MOV files. When I have files about 1 GB it seems to work fine. But if I have a large file, e.g. 1 hour HD video in 3,5 GB size, it loads the video, but the playback and any kind of edits does not work properly. Sometimes I am able to start the video, but it stops after a few minutes and I can't rewind or move forward. In the most cases Adobe Premiere crashes. But also restart or opening in new projects does not help. I wonder if somebody has similar problems. My understanding is, that I have enought RAM, and fast processor, that it should actually work fine. The video files are OK. As they run in Quicktime with no problem. Also moving back and forth in the video is fine in a simple player, but not in Premiere.
    Any ideas? And thank you for your help in advance.

  • Can mid 2011 macbook air use early 2011 macbook pro's RAM?

    I just upgraded my macbook pro's ram from 4gb to 8gb.
    Can I put my stock early 2011 mbp's ram into a mid 2011 macbook air?

    No. The MacBook Air's RAM isn't upgradable, except when configuring a model in the online Apple Store.

    thank you.

    A Mid 2010 MacBook Pro supports 16 GB of memory without any problem. Macs are "special" about memory because some brands work without any problem and others don't work. That's why I recommend you to buy the memory from OWC or Crucial in order to make sure that you get compatible memory > http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3

  • Why does my 2012 macbook pro 4gb ram run slow sometimes?

    I've purchased my 2012 4gb ram Macbook ram w/ 500 gb hard drive around September. It started off extremely fast the first 4 months (when I had mavericks), but there we're problems with the Video playback towards the last 4 months (It would Freeze and unfreeze & the the audio-video sync would be way off after 30 mins of netflix, which would cause the whole computer to slow down). So, I installed the Yosemite update, which made it even worse to the point where my macbook was unusable. With yosemite, I'd have an average of 500mb ram free memory available, sometimes even lower. Now, I did a manual restore to OS X 10.8.5 Mountain Lion, and I see the major difference in speed.  I could use safari now & get an average of 1.47 gb of free ram available (with just the safari application open). Now, the video playback issue still occurs sometimes & having about 4 programs open does make the computer slower than usual, but not as often. I'm hoping this is just a ram issue, becuase I'm expecting on upgrading my ram to a 16gb ram or higher while still on Mountain Lion just to be able to run Logic Pro & Adobe Premiere in the near future. If its not a ram issue which is causing this problem on my macbook, I'd be ****** because I'd be spending almost $200 on a ram upgrade and it not resolving this issue would kill me. Could someone help? Ill even take a Diagnose test like Etrecheck if you need me to. Thanks.

  • Macbook Pro 16GB Safe? I know-there's other postings about this.

    Hi everybody.  I've read on a lot of posts that the late 2011 Macbook Pros can handle 16GB of RAM.  I haven't, however, seen any sources that site whether this is safe LONG TERM for my computer.  Perhaps this is just because these RAM sticks have not be affordable until recently, but does anyone know (preferably with a credible source) whether this amount of RAM will do any damage to my computer over the next 3-4 years (I'd rather stick to slower speeds if it means it will last longer).
    Thanks!

    Apple staff monitors these posts and users, we have a rating system too.
    If anyone gave bad advice they would be flagged immediatly by options us upper level users have available to us.
    So no one lasts long around here with bad advice, opinions differ of course. In your case based upon decades of computer use around here, we never have heard of RAM actually hurting a users machine. Everyone is pretty much in agreement that the correct RAM specs in the correct machine, installed properly nearly all the time results in no long term problems.
    You could install RAM that is bad or glitchy, but that would show right away and you simply have it exchanged with no harm to the machine, unless you kept it in on purpose to do damage.
    What occurs is Apple releases new hardware that can say accept 16GB of RAM, but 16GB of RAM modules isn't availalbe yet (may not come at all), only 8GB, so they standardize on 8GB in their manuals etc, buy huge amounts of 2-4GB modules at discount prices and has to get rid of it.
    The savvy computer user knows the machine can handle more RAM and buys it elsewhere when the price comes down to somewhere they can afford. 16GB of RAM is going for about $250, it was well over $1000 a year ago.
    This has been the situation for many years with computers and Apple, as long as you buy the quality RAM of the right specs, the machine will handle it because Apple designed it to do so. Also they designed it so you can replace it yourself.
    Naturally you will either have to install it yourself or have someone do it for you, Apple won't install 16GB as they need to sell their 8GB off. Also they charge a crazy amount, like $435. LOL!
    Believe it or not, you can install RAM and hard drives/SSD in the Mac "Pro" lines yourself and not void the warranty/Applecare as long as you don't break anything, strip the screws and so forth. The replaced RAM and storage isn't covered of course.

  • Macbook Pro Sluggish:  RAM or Processor?

    Hi,
    I have an early 2011 13" Macbook Pro with the i5 2.3GHZ processor, 4GB memory and 500GB 5400-rpm SATA HD.  I'm running Lion OSX 10.7.4 and have a 24" external monitor (samsung) that I use as my primary screen.  My work involves a lot of data analysis within excel/R and simultaneously use a variety of other apps (Skype, Omifocus, Mail, iTunes, Adobe Illustrator, Dropbox Toggl and a few other menu-bar/background apps to help manage my workflow).   Now I understand I can't be firing away at everything at once but where I'm encountering unbearably slow performance and lagging are in the following areas:
    * Large data table processing (commonly in excess of 250k rows) within excel
    * Simulatneously using Excel, Mail, Skype and Omnifocus then trying to open another program
    * Random other instances of multiple program use
    My question is, how can I tell if my RAM or processor is at fault?  I've done some research around the Page In/Page out but I'm not 100% sure if it tells the whole story.
    Bottom line is I ordered a RAM upgrage 16GB since it was less than $200 from crucial.com but I'm wondering if I need to invest in a new iMac or Macbook pro with a faster processor, SSHD and 16GB of RAM.
    Thanks in advance for any help!

    Your macbook is fine.  The reason you're having issues is because you only have 4GB of RAM have several apps running in the background.
    Once your new RAM is installed, you'll see quite a difference in how your macbook handles multiple apps running at the same time.
    No need to buy a new one since the one you have is still considered fairly new.
    Add your RAM and enjoy your macbook.  I'm sure you'll enjoy it for years to come, especially when you get your new RAM installed.

  • Please update the specs for the MacBook Pro - 8GB RAM Max

    Hello,
    Someone needs to upgrade the specifications for the MacBook Pro now that 4GB laptop SoDIMMs are shipping and compatible with the MacBook Pro.
    See my blogpost on the subject at http://blogs.technet.com/keithcombs/archive/2008/07/05/testing-my-apple-macbook- pro-with-8gb-of-ram.aspx.
    Thanks,

    Hello again,
    Regarding having them update the specs, one can dream. Dreams are free. LOL. Hopefully the memory makers will update their specs as more makers start supporting a large memory configuration.
    The 4GB sticks I am using are http://shop.kingston.com/partsinfo.asp?ktcpartno=KTL-TP667/4G
    I did not do an extended test of the sticks in my MBP. Their home is in the ThinkPad I have because it is running Windows Server 2008 with Hyper-V.
    As you can see from the link above, these little suckers are pricey. But consider the price of 2GB SoDIMMs were $950 when they entered the market a couple of years ago. The price will drop.
    I asked the Kingston rep that sent these to me if online sites like newegg.com would have them soon. She indicated no, but the corporate buying sites like CDW and Zone would. So check around. They just started shipped a couple of weeks ago so be patient.
    If you have any other questions, please stop by http://blogs.technet.com/keithcombs/archive/2008/07/05/testing-my-apple-macbook- pro-with-8gb-of-ram.aspx and ask there. I'll see them much more quickly.

  • 64-bit or 32-bit for the 2011 (spring) Macbook Pro 8 RAM 500HD?

    I wanted to know the differences between 64 bit and 32 bit OSx I am currently running the latest Lion 10.7.3 on a 2011 spring macbook pro with 8 gigs of ram 500 gigs HD. From what I can read in the info it looks like it defaults to 32 bit automatically but I was told that I can hold down the 6 and 4 keys during startup to start with 64 bit. I would just like to know anyones experiences and what software it works better with. I usually run Adobe CS5.5 and it would be great to find out 64 bit will give it a boost. Please list pros and cons you know of..
    Thanks..
    Pete

    It should be running 64-bit on its own with Lion. My 2007 MBP began running full 64-bit after I installed Lion.
    Run the Activity monitor and see what the kernel is using. It should show 64-bit.

  • Older Macbook Pro's Ram Capacity?

    Hi.. I have the older macbook pro... (one just before the new ones came out), and it is said that 3GB is the capacity.. so if i got 2x 2 gigs of ram installed, would it not work? thanks

    Hi and welcome to Discussions,
    see this article: http://docs.info.apple.com/article.html?artnum=304662
    You can install 2 x 2GB and it should work, although only 3GB are usuable.
