12" powerbook ram upgrade

I have a 12” powerbook G4 with a 1.33GHz processor and have noticed that programs have been running a bit slow on my 256 of factory installed ram. I have one slot available for adding a new stick and am not sure if it is worth the money to put in 1Gb or just triple what I have by adding in 512. A gig stick is 3-4x the cost of the 512 & I don’t run any major major memory burning programs. Any advice? Thanks

  • Powerbook G4 17" motherborard failure after RAM upgrade???

    Thank you in advance for any advice.
    I have an original, first generation PB G4 17" that I've used for 5 years. Recently, I had to replace the AC supply because the former one was bent when the laptop fell out of a chair. When I took it in to an authorized dealer here in Taiwan, to test the power adapter, I decided to upgrade the RAM from 1GB to 2 GB. Before I brought it home, it seemed to work at the store, although I thought I did not appreciate any performance boost when I opened multiple apps. Anyway, after I got home, I tried to turn it on, but it would not turn on. Thinking the battery was depleted, I hooked it up to the new AC adapter (Apple brand), and lo and behold it would not boot. I would shut it down by pressing the on/off button or just disconnect the power source (adapter and battery). It started to beep three times after multiple attempts. I took it back to the store, and got my original RAM reinstalled, and the same three beeps occured. I just got a call from the service center and was told that the motherboard has failed. Does any of this make sense? I have never had any trouble like this prior to the RAM upgrade. I just replaced the HD about 6 months ago. I'm just sick to my stomach...Any suggestions? Any input would be much appreciated.

    Welcome to the Apple discussions.
    We could discuss how you'd benefit from the additional memory, however, since the system isn't working, let's focus on the beeps.
    When you start the system, it goes through some tests (called the power on self test or POST) before loading the operating system. If it finds any errors, it beeps, and the beeps are:
    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
    5 beeps = processor is not usable
    3 beeps means it doesn't find any memory that passes the POST test. The fact that this started up after the service center installed the memory upgrade is suspicious, however, if it worked in the store then stopped working later, it may just be unfortunate timing.
    There are some company's on the internet that claim they can repair the logic boards, otherwise, Apple's solution is to replace them. In the US, some Apple stores offer a 'fix everything' service for $350, which is less than specifically replacing the logic board - perhaps there is a similar service in Taiwan.

  • Factory Original PowerBook RAM?

    What brand of RAM did Apple ship with the PowerBook G4 15" 1.5ghz, and is this the same RAM you would get if you bought RAM through the Apple Store? Looking to upgrade my RAM, and from all of the headaches other people have had with PowerBooks and RAM upgrades it seems like the best route would to be to get the same RAM that the PowerBook originally shipped with.
    PowerBook G4 15" 1.5Ghz   Mac OS X (10.4.3)  

    Welcome to the Apple discussions.
    Last year, Apple was using Samsung memory. Apple would love to sell you additional memory, as you generally pay twice what you could buy it for on the open market.
    Generally, the only time people have difficulties with RAM is when they try to go cheap. We know the PB's architecture is RAM-sensitive. If you stick with known brands, three of which are Samsung, Crucial, and Kingston, you should be OK. Crucial, www.crucial.,com, guarantees its RAM will work as long as you use their web site memory selector. I'd expect Kingston would too (note, their Valueline RAM isn't for PB). Lifetime warranty is helpful another indicator. I've used all three brands manufacturer's recommended RAM sticks in PB's, with no issues.
    If you go Kingston and want to order from their website, www.kingston.com, click specials, click promotions (might have those two reversed), click notebook memory, do the machine lookup, and you'll save up to 25% off their list. They also give you prices from several other sellers.
    One seller of Samsung is Other World Computing, and their memory is http://eshop.macsales.com/shop/memory/iBooks-PowerBooks/G4-Aluminum/ Samsung is about half way down the page under the 'OWC PC2700....' category.

    First go to the RIM web site and look to see if they have an uninstaller for the device you had.  Some times a reinstall of the application and then running the uninstaller is required for complete removal.
    If no uninstaller is available, then you will have to use Spotlight to find all items with 'Blackberry' and 'Rim' in the titles.  I would also download EasyFind and use that to locate such files.  Often it will locate items that Spotlight misses.
    Ciao.

  • HP Envy 13 1030nr. Windows 7 64-bit. RAM upgrade help.

    I just purchased a RAM upgrade for my Envy 13 and I was trying to figure out how exactly to access the memory module.  I couldn't find a youtube video for the Envy 13 and reading the maintenance manual provides only partial instructions to access the memory module.  It tells you what you need to do (Disconnect the TouchPad cable 2 from the low insertion force (LIF) connector on the system board) but not how to do it without damaging the computer.  I don't want to permanently sever a cable or anything so I'm looking for help via a link to a video or more detailed instructions on exactly how to safely access the memory module. 
    I was under the impression that this would be a quick replacement, but the more I read the manual, the more I think that this is going to be a little more complicated than opening up the bottom and removing the current RAM chip and replacing it with the one I have.  Any help would be appreciated.  Thanks!

    Here is the Manual:
    Manual
    Memory is indeed on the motherboard and getting there requires nearly complete disassembly. See Page 4-26. Not sure how this qualifies as "easy" and if you have not done this before you should get some help. And yes, keep careful track of those screws. 

  • Hard Drive and RAM upgrades for latest 15" MBP

    I'm minutes from ordering a new MBP. Only concerns are whether I get hte Apple upgrades or shop around.
    I like this Hard Drive...
    http://www.compu2000.com/index.php?l=product_detail&p=6433
    And this RAM upgrade...
    http://www.a-power.com/product-10937-311-4
    If these are equivalent to the apple options I can save hundreds and get a 320 GB drive, which will make a great portable.
    So, does my plan hold water?

    You're on your own for support when you do your own upgrades like this, but generally speaking, it works fine.
    Note that HDD is less risky than RAM. With RAM you run the risk of unstable behavior that is tougher to diagnose. That said, a quality RAM upgrade and some initial testing with any of many available tools is as good as a factory build.
    HDD upgrades are less risky, and I've upgraded (well, replaced after HDD death) ones in my MBPs many many times. I crunch my hard drives more than normal and have to generally replace them about every year. Some of the MBPs don't make this easy, and prepare to get all sorts of cozy with little 0 and 1 sized Phillips screwdrivers and some T6 as well, but it is doable (just not quite for the truly faint of heart).
    Again, you're on your own for support once you do this, so weigh that in your decision.

  • This is the regular status of the memory of my macbook pro. Do you think I need a RAM upgrade?

    Hi there,
    I'm hoping to seek the expert views of the community here.
    I have a MacBook Pro, Late 2011, 17 inch. Running latest version of Mavericks. Speed seems to have slowed somewhat, perhaps since I upgraded to Mavericks, but not certain about that. Based on my research of the Apple communities, I suspect that I may benefit from a RAM upgrade.
    Attached are a few screen shots to assist:
    Based on what I have researched in the community, the fact that I have used 3.99GB of 4.00GB, and have used 5.63GB of Virtual memory, seems to suggest to me that I have well and truly maxed out my RAM. Also there is a high number of read ins/outs (but it had been a wheile since I last did a restart on the MBP (if that has any effect on these numbers here).
    I have also read that my model of MacBook Pro is upgradeable to 16GB of RAM (2 x 8GB).
    Thoughts and views from the community would be greatly appreciated. Will additional RAM help the speed and performance of my MacBook Pro?
    Many thanks.

    More RAM is always a Prudent move...

    After the RAM upgrade, FCP timeline will play but video is black in the canvas and image is frozen on the NTSC. Video WILL play in Viewer but no audio.
    All cables have been checked to make sure they were put back correctly - will keep checking for errors in re-cabling computer.
    Have tried refreshing displays and other tests with displays. Any info would be greatly appreciated.
    Thanks!

    pull the ram, problem goes away? - bad ram
    you can pull 2 sticks at a time to isolate which chip it is.
    did you get it from a good source - Crucial.com is my favorite, OWC is popular too - both have lifetime warranty

  • 24" iMac (Primo 2009) strange RAM upgrade issue

    I have a 24" iMac (Primo 2009) at work. I been granted a RAM upgrade by the IT department and have received 2 indentical 4 GB modules.
    The 24" iMac (Primo 2009) uses 1066 MHz DDR3 modules and supports up to 8 GB RAM in 2 slots. I have purchased RAM from this source http://www.dustin.dk/product/5010642132/corsair-4gb-ddr3-1066mhz-1x4gb-so-dimm-i mac-macbook-macpro/#intcmp=searchProvider_SiteSeeker (Corsair Mac Memory so they SHOULD be fine.)
    Here's the issue:
    I had 2x 2GB modules. I have taken both out.
    I have inserted the new 2x 4GB modules but the machine refuses to boot. It gives off 3 beeps-interval-3 beeps-interval (repeats).
    I took out one of the 4GB modules from slot B. It boots.
    I inserted the one I removed in slot B again so we're back at 8GB. same beeps. No boot.
    I switched the 2 4GB modules from slot A+B around. Now beep-interval-beep-interval (repeats) No boot.
    I inserted one 4 GB in slot 1, and one of the old 2 GB in slot 2. It boots with 6GB RAM.
    I inerted only the one that won't boot when in slot B in slot A, beep-interval-beep-interval (repeats) No boot.
    OK - so logical deduction tells me one of the new 4GB RAM modules is defective. No matter what configuration, booting fails with that specific module inserted, though there are different beeps. I also know tha both slots work since the machine works with 6 GB RAM (2+4).
    So I called Dustin, and since we're a big customer they sent a new moduel for free. But, I have the same isssue with the new module!! What are the chances I have recived 1 working and 2 defective modules? not big right? So my iMac seems fine with the old 2GB modules and one of the new 4 GB modules, but says no to the 2 other 4GB modules.
    YES - I have tried resetting PRAM and SMC to no avail. Any clue?

    Switched the 2 modules around, so there's now a 2GB in slot A and a 4 GB in slot B. Still works fine

  • Kernel Power error after Win 7 and RAM upgrade

    Hello,
    I posted earlier on the subject of win7 and ram upgrades.  I did both and it seemed to go fine.  I did the ram first ... replaced a 667Mhz 1gb with a 800Mhz 2gb.  A couple of days later the computer just shut itself down and restarted.  Since then it has done it another 5 times, seemingly at random.  Yesterday I decided to spend some time looking into it and found the 'event log'.  All the shutdowns are recorded as 'critical'.  A search on the web/here showed other occurences of the fault associated with drivers as much as anything.
    After I did the win update I did update almost every driver with ones from this site.
    Other than the shutdowns the only issues I have which are of very mild concern are the length of time the fingerprint reader takes to be present and that occasionally the cursor is unavailable for about a minute after logging on. When you try and control it it jumps about anywhere but where you want it to go.   I rolled back the alps driver and that seems to have sorted the cursor issue.
    So, details of the shutdown from the event log are as follows.

    There's more (I've shown it all below) but it's not that important.  When I looked into it I found details of the problem on the microsoft knowledge base.  Its described here http://support.microsoft.com/kb/2028504.
    I believe I fit into scenario 3 for cause and resolution.
    So, it seems that win7 and mixed speed ram may be a problem on some computers ... probably only a tiny number, but it looks like the HP3507 is one of them.  I did see somewhere that I could down speed from 667 to 266 which might help with memory compatability but I can't see anywhere on the the insydeH20 bios where to do it.  BIOS is version F18 .... upgraded from F15 as part of the Win7/RAM ugrade.  
    Before I swap back to the 'old' memory I'll see if anybody here can come up with any ideas.  It may be that I have to sell off the expensive 2gb memory (ddr2 800mhz 200 pin) for £39.99 from maplin at a bargain price and get 2gb of 667Mhz from somewhere.
    The full 'detail' regarding the fault is below.
    Bye for now.

    Hi DWeiland and Schwede,
    Thanks for your replies. Yes I did the runtime engine registry change and also mass compiled the LV7.1 folder and my sourcecode. I still see the problem as I have set the LV adapter as Lv 7.1.1 runtime engine. Now I have changed it to LV7.1 development system. With this setting, it is not giving any error. Thus I don’t see any problem now. The older version of the code had the adapter as the runtime engine for some reason, now I have changed the setting to the development system. I hope that it shouldn’t be a problem.
    Thanks again!
    Thank you,
    Sasi

  • Mac pro 5,1 RAM Upgrade

    I am planning to give my Mac Pro (Mid 2010) another RAM upgrade. As the official Kingston/Crucial DIMMs do not include 16GB DIMMs, I think of choosing Kingston Value RAM: ECC Registered (3x, 16GB, DDR3-1600, DIMM 240). Has anyone here in the forum tried these?
    Thanks for your comments.

    The biggest official Kingston part is KTA-MP1333/8g which is a single 8GB module.
    For 16GB modules the main criteria are that
    It must be registered memory - not buffered, this is more because there aren't any 16GB buffered DIMMS
    You cannot mix registered and buffered so any other existing memory left fitted must also be registered, as it happens you are supposed to not mix 16GB with smaller sizes anyway
    It should be 1333Mhz DDR3 although in theory 1066Mhz DDR3 would work, again I don't believe there are any 16GB 1066Mhz DIMMS
    It should be ECC (error correcting)
    CL9
    The presence of a Thermal Sensor is apparently not compulsory, i.e. memory without it will work in a Mac Pro.
    I have not used any 16GB DIMMS myself but other than OWC as per the link provided by Illaass, the following might be suitable
    KVR13R9D4K4/64i - this is a kit of 4 x 16GB and this article has a post from someone who says they worked for them http://forums.macrumors.com/showthread.php?t=1493588
    If you can find a kit of 2 x 16GB of the same type then logically they should also work, they would probably be KVR13R9D4K2/32i. As a reminder to do 64GB or more you need dual processors. The single processor model Mac Pro 2010 is limited to 48GB.

  • Display problem after RAM Upgrade to MS6712

    Hi there,
    after a RAM upgrade (512mb to 3GB) my PC has developed a display problem. The graphics are slow / rippled and video playback is very poor. In device manager no "display adapters" are present and there is also an error mesage referring to the VIA CPU to AGP2/AGP3.0 controller not having enough free resources to run due to a conflisct with VGAsave? I've downloaded the latest VIA chipset drivers to no effect?
    System info: MS6712 MB, AMD Athlon 1.25GHZ, XP SP3.0

    OK, here's the info on my PSU;
    It's a Powerman FSP250-60GTU(PF). Input: 230V - 5A, 50Hz. Max Output: 250W
    While I had the case open I took out 2 of the RAM modules and without making any other changes everything appeared to work fine with just the 1GB, so I tried putting 1 more back in to take it to 2GB and again all seems fine? Does this indeed point to my PSU then? If so and it works fine with 2GB should I be thankfull for a 512mb to 2GB upgrade and send the 3rd module back to Crucial??
    Before I posted this thread I did run a memtest from Memtest86+ with all three modules installed and it came up with NO problems?
    Re Henry's post, I searched using the format of the part no on the RAM modules themselves i.e. M368L2923FLN-CB3 and it took me here:
    http://www.samsung.com/global/business/semiconductor/productListNonflexTable.do?fmly_id=118&sht_id=1
    Other info on printed the modules themselves: 1GB DDR PC2700 CL2.5
    According to Everest my CPU temp (with 2GB installed) is: 43 degrees (MOBO 30 degrees and HD 42 degrees) - do these seem normal?

  • Do I need a RAM upgrade

    Hi- I've got a PB 1.67GHZ (aluminum) with 1GB RAM (2 512MB chips).
    I tend to leave lots of apps open (around 10) for my workflow. I'm always having to jump between apps. None of them are particularly taxing though I do play one game that takes over the system (so I shut down other apps for that). My system definitely gets slower with lots of apps open.
    Currently, my Activity Monitor shows page in/out as 307943/213848. I'm thinking that second number is not good and I ought to get some more RAM.
    In addition to recommending a RAM upgrade, should I go for just an upgrade to 1.5GB or go for 2GB?

    Your system is memory deprived. The general guideline is that page outs should be 10% or less of page ins. Yours are currently about 69%, meaning for every 10 page ins, your system is paging out roughly 7 pages. A page out is where the system has to move something out of memory to disk to make room for something else, and that impacts performance.
    You can upgrade to 1.5gb by installing a 1gb RAM strip, and monitor your page ins/outs and performance/feel. For what you run, that may do it for you. However, if you don't see much improvement, then going to 2gb is available to you.
    Recommend Crucial, Kingston (not their valueram line), or Samsung memory, which has proven reliable in our PB's. Crucial can be found at their website http://www.crucial.com , Kingston at http://www.kingston.com , and Samsung is available from a number of companies, of which OWC at http://www.macsales.com is one source.
