Powerbook G4 15"-ram expansion possible?

Hi everybody
I have a Powerbook G4 15" 1.67 GHz with 2GB Ram.
Is it possible to expand Ram to 4GB?
Fabio

fabthi:
To confirm Frank's response, your computer will support 2 - PC-2700 DDR333 200-pin SO-DIMM. The maximum RAM supported is 2.0 GB.

  • What is the maximum ram upgrade possible on a Mid 2011 iMac 21.5-inch

    I have an iMac 21.5-inch, Mid 2011 running OS X 10.9.5 which currently has 4 GB 1333 MHz DDR3 Ram. The Hard Drive has 149.87 GB free out of 499.25 GB. It has been running slow for a while now. I would like to know what is the "TRUE" maximum Ram Upgrade possible. The reason I say "TRUE" is because the specs say one things when I find others saying another. I would like to install the maximum Ram that will increase the speed to its optimum. I have read some information that this particular computer will not take advantage of anything past a certain amount of ram.
    So with all that said, I am asking for specific numbers, types of ram, suggestions etc etc...
    Thanks

    Here's what you can do and need:
    Maximum Memory
    32 GB (Actual) 16 GB (Apple)
    Memory Slots
    4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM
    Sources for memory I recommend are:
    OWC
    DataMem

  • RAM expansion from 512 to 1024 MB. Much better ?

    hi,
    I want to enhancen the standard memory of this tecra M2 from 512 to 1024 : does that give such a faster computer or is the gain not that worth ?
    Thanks in advance

    Hi
    RAM expansion is always good and thereby the notebook efficiency goes up. I do not know for which kind of work you need your unit but if you make some complex diagrams or design work I believe that you will be able to remark that the notebook can much better and faster finish all given processes.

  • FCPX undo / auto save bugs + RAM Hog - Possible Fix?

    Hi there FCPX users,
    I have a 8-core 2010 Mac Pro with 16GB Ram and the stock GPU running Lion 10.7.2
    I have been using FCPX since day dot, and have been overall very pleased with its super fast work flow and realtime capabilities.
    I have completed over 100 3-4min edits with average project size of 50GB, and a bunch of wedding edits with approx 150-200GB project sizes. The issues I had with 10.0.0 - 10.0.1  were mainly FCPX quitting unexpectedly.
    And now on 10.0.2 I have expereinced the well known auto save / greyed out undo bug. I have gone through all the steps via apple care which included:
    Trashing the Prefs, repair permissions, check drive space / correct format, new user account and clean install of lion / Final Cut X.
    I am still experiencing this issue. So yesterday I purchased another 16GB Ram totaling now to 32GB Ram, and I monitor the RAM usage via "Free Memory".
    I Noticed that if my RAM is running low, I "free Memory" without quitting FCPX and continue to work as normal, and so far I have not yet experienced the issue again.
    Dont know if this is a temporary fix, but it has worked for an hour long edit (approx 6-7 hrs without restaeting FCPX).
    Also, I have noticed FCPX will eat up 16-20GB RAM quite easliy.
    Not sure if this problem is related to RAM...
    My 2 cents.

    You have to really be conscious when you start a new project and how and where you manage your footage.
    No one has complained more than I have about FCPX's quirky behaviors and it can be frustrating. I have worked with FCPX since day one, even tried to get a refund but couldn't. After using it for a while now, it is very easy to get used to how fast some elements are in editing and reviewing a lot a footage. But several things you have to make sure of that will keep the rendering speed up and less crashing happening.
    First make sure that you can see how much space you have on your drives by right clicking in the main window of you screen and make the necessary clicks form the drop down menu. Make sure any drives you have been doing projects with lately are hooked up and do a secure empty trash. Its cool to see how much space you regain. 2) make sure that FCPX, Motion and Compressor (if you have those are installed on your boot drive).
    3) Create a FCPX Projects folder on an external (FW800) with at least 75% of its drive space available if you do not have secondary drive installed in your computer. (Its very important to note that any drive you use for any aspect of editing should never be more 75% full, especially your boot drive.) This is where FCPX will log all of its operating files for all of your projects.
    4) Either copy  all of the other FCPX files from your main hard drive and paste then into the new folder you created. Then delete all of those files, as well as any Motion files too! (Do the same as you did for FCPX in the previous step)
    5) If you need to move all of your music files to another drive as well. If its iTunes, you will have to tell iTunes where to look for the new files and it will populate accordingly. This will free up a tremendous amount of space. Make sure to delete them form the main drive.
    6) Remove any junk programs form the boot drive (main) or move them to another drive if possible.
    7) Now do another secure empty trash and watch your drive space return.
    8) Now open up FCPX and make sure you only create projects on your new drive by clicking on that drive in the project window. Any older projects you can simply pull them to the other drive and you will be prompted on how to duplicate that project and all its files to that drive. Delete the other ones.
    9) Only capture footage to you external drives. Save it there until you need it.
    10) Create all new projects on the secondary drive and pull any footage you are working with on that drive as well. By keeping it all off the Boot drive FCPX will run much smoother and faster, especially if you have at least 16g of Ram, which I recommend.
    So to re-cap:
    1. Keep your boot drive lean. Delete anything you can move to another drive. Do not set up events and or projects to it...never!!!
    2 Use you secondary drive for your project files and the video you are working with in your events.
    3. Store raw footage on a FW800 drive ready to move to your secondary drive.
    4. Use secure empty trash after all editing sessions when you are certain of your trash contents.
    Doing these things have greatly increased much more consistently faster render times and much fewer crashes.

  • Mac Mini 2010 - RAM expansion fails

    Been trying all morning to expand the memory of my 2010 Mac Mini from 2GB to 4GB
    Picked up 2x2GB ADATA SO-DIMM modules, 1333Mhz.
    As soon as I put both in at the same time the machine simply will not boot. Putting one of the modules in either slot works fine for 2GB of RAM (tried all 4 possible combinations) and OSX reports the modules running at 1333Mhz just fine.
    Mixing either one of the new modules with either one of the old works fine in all possible combinations as well for 3GB total RAM reported by OSX as running at 1066Mhz which makes sense as the Samsung modules it shipped with are 1066Mhz modules.
    So I'm stumped, the modules are fine, they work fine in the Mini they just won't work together at the same time.

    I'm sure the rated speed of the modules doesn't make a difference in Core2Duo based machines as the chipset is the one setting the speed and not the module itself. That 1333Mhz is simply what ADATA believes is the maximum it can reliably run at. When provided with a single 1333Mhz capable SO-DIMM the Mac Mini happily runs it at 1333Mhz as well which makes me suspect the 1066Mhz RAM it is shipped with is solely out of financial consideration.
    ADATA itself claims on it's this specific module has been tested with all Apple products
    Seems others are having the same problem with different sets of memory. One module working fine but both not. Unless Apple releases a firmware update to fix these incompatibilities I think it's a dead end. The ADATA modules moved on to the iMac where the are working fine and I got a kit of OCZ 4Gb 1333Mhz SO-DIMM's that work fine in the Mac Mini.
    Thanks for the help so far.

  • IMac 8,1 2.66Ghz Core 2 Duo maximum ram upgrade possible

    I have an iMac 8,1 2.66 Ghz Core Duo, right now I have 2Gb Ram, and I am going to upgrade it. Some forums suggest that it is possible to install a 2GB and a 4GB slot to get 6Gb, and some others says it is better leave it up to 4Gb. Can someone tell me if I should go for 6 or 4GB, I obviously prefere going for 6. Thanks

    6 GBs is the max.
    Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).

  • Is a 16gig/RAM upgrade possible 13" MACBOOK PRO 2.9ghz if so is it worth it or am I better off with a 15" MBP?

    Forgive me for trolling on this topic but I wanted to be a bit more specific and get properly eductated before I make a final decision.  I had a 17" and I f@cking hate it because of it's size.
    I have been a mac guy for a few years but up until now I relyed on my tech/junior assistant to deal with all the tech stuff.  He has now gone and on his own leaving me to get all techy again. 
    A little about me and what I will use the laptop for. 
    I am a photographer/film maker. I run CS6 very often sometimes daily.  I usually have multiple picuture files open with multiple layers.  Some images can range to a size of 600mb+.  I shoot with cameras with no less than 18 megapxls.  On top of that I may also have FINAL CUT PRO and working on short films.  I generally have the habit of jumping back and forth between the two, plus get distracted with the web and stream videos. and the od video game (but not so much). 
    I keep reading that 16 gigs of ram is a possible upgrade on a 13" macbook.  Is it possible?  And if so, what sort of performance boost can I expect (in comparison to the 15" MBP?  Also, if so are there any glitches that may damage the computer?
    1.  I travel quite a bit I really prefer the portability of the 13" MBP and want to avoid having to buy te 15" MBP
    2.  I am attempting to be cost effective (which may be a futile attempt)
    All answers are welcome. 
    Thanks for your time and have a fine day Ladies and Gents.
    Cheers

    Thanks mate but it doesnt, answer the question about performance. 
    In terms of screen real estate, I don't care much for it as I usually work relatively close to the pixel sizes and I generally work in very dum conditions so the antiglare is something I also dont care for.  If mac offered a Matt finish screen again it would be a dream lol.
    Retina though sweet is really just a gimmick, stare at one screen, starred at them all, so I'm fine with the regular MBP.
    And size does matter.

  • New PowerBook AirPort and RAM issue

    Sorry to re-post but thought others could benefit from this being up top here ...
    I have a new 17", but have a big red flag for people.
    I couldn't get the extra RAM (over 512MB) from the Apple Store where I bought it Saturday, so I ordered it online from Apple and installed it last night. Easy! Then, PROBLEMS!
    After about 20 minutes online, suddenly the cursor's skittering around, CPU spikes to 100% and stays there (kernel_task, owned by root, takes over), and AirPort drops. Can't find any networks, and stays offline. Only known fix is a reboot.
    I checked MacFaxIt and see these exact symptoms are an issue, supposedly acknowledged as a bug by Apple, with mid-2005 iBooks. I guess you can add late-2005 PowerBooks to that list.
    Looks like the key is to keep RAM usage under 1GB, which is not necessarily easy to do (and goes without saying, should not be something you need to manage). For example, loading a lot of tabs automatically in Safari kills AirPort pretty consistently. Loading a lot of widgets does the same.
    I'm walking on eggshells with this PowerBook, constantly checking CPU usage and AirPort connectivity, NOT something I want to have to be thinking of.
    So be careful adding RAM. My last PowerBook (very last gen) had 1.5 GB and NO PROBLEM.
    I don't know of any timeline for a fix, and am more than a little upset that (1) the problem exists on a $3,000 machine, (2) Apple has known about it since late summer, and gladly sells you the RAM (caveat emptor), and (3) the in-your-face that the PB and iBook are probbbbbably kinda sorta the same, under the hood! So I'm telling myself that yes, it's a SOFTWARE problem with OS X, the extra RAM, and AirPort. Works for me ...

    I MAY have a potential solution.
    I had the same problem as others, bought the Powerbook with 1 GB Apple memory and then I added another 1 Gig of Kingston brand memory. Almost immediate problems and after a reboot, the problems would come back in 5 minutes or less.
    I called Apple and they refused to even acknowledge that it was a known issue.
    OTOH, the tech had me remove the new 1 GB memory stick and of course the Airport card worked perfectly after that.
    Anyway, when I put the memory card back in, I seated it quite firmly before I "folded" it down into the latches.
    Bottom line is that Airport has now been working for over 4 hours with no problems.
    Can anyone else who is having the problem please try this & post the results. If the solution is this simple, it would be a wonderful thing.
    The System Profiler showed that the memory was there before I reseated it, so if it is just a bad card install, System Profiler does not pick it up.

  • RAM from Powerbook vs. RAM for MacBook

    Because Apple could not repair my Powerbook 17-inch, they replaced it with a new MacBook Pro. Now I have 2 GB of RAM I had installed in the Powerbook that I'd like to sell or trade for additional RAM for the MacBook. (I assume that the PC2-4200 from the Powerbook is not compatible with the MacBook -- please advise if that's incorrect.) How do I get some value out of the practically brand-new RAM from the Powerbook (which cost me $310 new in 11/2005)? I assume that the best way to get an additional 1 GB of RAM into the the new MacBook is simply to buy the appropriate RAM chip and install it -- but I'd appreciate any suggestions on that too.

    Terry
    You're correct,The PowerBook RAM is not compatible with the MBP.
    As far as selling the old RAM,Ebay is an option.
    Although I seriously doubt you'll get anywhere near what you payed for it.
    For new RAM,I use and reccommend OWC... http://macsales.com

  • Maximum RAM upgrade possible on a mid 2011 iMac 27"

    Can I upgrade my mid 2011 Imac 27" to 32 gb of RAM.  Apple handbook says  only possible to upgrade to 16gm (4x 4gb cards).  Has anyone upgraded a 2011 Imac 27" to 32gb of RAM?

    Yes, both OWC, http://www.macsales.com and Crucial, http://www.crucial.com offer 32 GB ram kits that are guaranteed to work...to do that you would be best to not buy from sources that are not Mac specialists and who guarantee their ram to work.

  • 15" Macbook Pro mid-2010, 16GB RAM upgrade possible?

    Hi all,
    I've been looking around all the support forums and questions asked etc..
    But I can't find a definitive answer about support for the 15" mid-2010 MBP being able to use 16GB (and be stable).
    I'm aware that it's perfectly fine on the 13" model, however I have the 15" i7.
    From what I've been reading it's because of the motherboard/Graphics chip/EFI BIOS incompatibiity with anything more than 8GB. (Which is silly really, as the same Intel core i7 can have up too at least 32GB of RAM on any none-Mac system.)
    Have Apple not pushed out an EFI BIOS update that could allow the use of 16GB RAM?
    If this has been clearly answered elsewhere (and I haven't found it), feel free to point me in the right direction.
    Thanks, Jon.

    Unfortunately, 8GB is the limit. I have the same machine. Why it works on the 13" and not the 15" is ridiculous, but that's how it is.

  • Macbook pro mid 2010 15" 16 GB ram upgrade possible?

    I recently purchased RAM from Crucial.com for 8 GB and after having researched a bit online I've heard of users upgrading to 16 GB.  Is this true? 
    Here are the specs of my cpu:

    OSX Yosemite 10.10.1
    Memory 8 GB 1067 MHz DDR3
    2.53 GHz Intel Core i5
    Can anyone give me insight?  I'm not very computer literate, but could use all the advice I could get.  Thank you kindly

    Good morning ipodsmut,
    The MacBook Pro mid 2010 model supports up to 8GB of RAM. See this Apple specifications article -

  • Memory upgrade on the NB550D-11D - 4GB RAM are possible

    To anyone who's thinking about a memory upgrade on the NB550D:
    The NB550D supports up to 4GB of memory, not only 2GB as mentioned by Toshiba in their specifications.
    A memory upgrade to 2GB is _only limited_ by the pre-installed Windows 7 Starter OS, not by the netbook itself.
    I'm using Linux Mint 11 Katya, 64bit and my system is running perfectly well with a 4GB ram module. If you want to use full 4 GB ram support, get rid of the Win 7 Starter OS.
    The specification for higher volume ram is DDR3 1333MHz PC3-10600 SO-Dimm. I've chosen one 4GB module by Corsair, due to the 30 years warranty Corsair offers.
    It took me quite a while to find this out, hope this is going to be a help to everybody who's just as unsecure as I was how to upgrade the NB550D memory. Good luck. ;o)

    > A memory upgrade to 2GB is only limited by the pre-installed Windows 7 Starter OS, not by the netbook itself.
    I can confirm this. Two days ago Ive installed own Win7 32bit Home Premium and upgraded my NB520 with 4GB RAM. 3GB are in usage now and notebook runs perfectly.
    With original Win7 Starter version I have noticed annoying display behaviour while watching action movies. When the scene in the movie was without movement everything was ok but by action scenes some strange lines were shown on the screen.
    Now after own OS installation everything works perfectly and Im so happy with my NB520.
    I can just recommend it for everyday usage.
    By the way: I use 4GB SO-DIMM DDR3-1333Mhz PC3-10600
