Problem with Ram upgrade

Hi, I have an Imac (27", mid-2011) and I just bought a 4Gb Ram memory to install in one of the free slots, I installed and turn on my computer, the computer recognized the new memory but when I'm going to open a program (and even when I leave the computer alone and I don't do anything) the computer restarts with the next message: "The computer restarts because of a problem". I think that is because the new Ram memory but I don't know what is exactly the problem. This is the report I have:

Thank you all.

1. You have two different brands, Samsung (M471B5673FH0-CH9) and Kingston (99U5469-035.A00LF).
2. Typically, DIMMs are symmetrically added, 2,2,4,4 or 2,2,2,2 or 4,4,4,4 and each Bank should have matched pairs in size and speed.
If you remove the 4GB memory do your crashes stop?
MACs are very specific about memory.
You can try this, but it may not work.
BANK 0/DIMM0 - 2GB
BANK 0/DIMM1 - 2GB
BANK 1/DIMM0 - 4GB
This is what you have now.

  • Problems with RAM upgrade iMac G5 1.8GHz

    Stuck - Need Help!
    I've previously upgraded up iMac to 2 500Mb RAMs and felt recently that it needed that little bit extra, so I ordered two 1Gb chips from crucial.
    Followed instructions to T, but with the two new chips in, the machine won't load.
    Interestingly, it boots up with the following RAM combinations
    old 500MB + new 1GB (in any combination) - recognised as 1.5GB
    one new 1GB RAM (again either one) - recognised as 1GB
    I spoke to crucial who said that as the RAMs work individually, there isn't a problem with them, it could be a Firmware issue. I've upgraded all my software, and don't know what to do next?
    Anyone overcome a similar problem in the past?
    Thanks

    I'm experiencing something very similar to shaow. I'll share my experience in gory details - sorry for the long post but I've spent more hours trying to stabilize. I should have worked the hours at walmart and bought a new iMac with the money I could have earned
    Anyway, here goes:
    Two iMac G5 1.8Ghz 17" (both Fall 2005 model), will call one A and the other B.
    Prior to attempting ram upgrade: A, config working fine: both a config using 1GB slot 1, 256MB slot 2 and a single 1 PC3200 1GB stick. OS X 10.4-10.5.7. No problems. I did have the motherboard replaced under warranty after having sleep problems - capacitors were expanded. No problems since that motherboard swap.
    Prior to attempting ram upgrade: B, config working fine: 2 x 256MB sticks. OS X 10.3.9
    Ordered 3 PC3200 400Mhz 1GB sticks from Data Memory Systems.
    Upgraded A: Added 1GB stick = 2GB total
    Upgraded B: Removed both 256MB sticks from B and added two 1GB sticks = 2GB total
    Booted B, experienced gray screen of death with the multi-language crash message - somethign like: 'Please hold down the power button and restart'. Power cycled B, booted off a retail box DVD of OS X 10.5.6. Began upgrade to 10.5.6. Gray screen of death part way thru upgrade. Power cycled, gray screen of death again during early boot phase.
    Decided to run tests on B. I could not locate the Apple Hardware Test (neither on system dvd 1 nor on a separate DVD). I resorted to using TechnoTools Deluxe which was included with AppleCare box. No hardware problems found including on the 2GB memory.
    Removed both new 1GB sticks, pulled older working 1GB stick from A and installed into B. Completed upgrade with just 1GB memory on B to 10.5.6 and subsequently pulled down all updates for OS X 10.5.8. Powered down, added second 1GB stick to B, booted into 10.5.8 successfully. Repaired disk permissions, restarted. Began using applications, then after only about 5 minutes experienced gray screen of death. Powered down, removed new 1GB stick, replaced with one of the two remaining new 1GB sticks. Read about reseting PRAM/NVRAM. Followed steps to reset PRAM then decided to do the reset NVRAM within openfirmware. Started back up and logged into 10.5.8. Ran several applications - did not experience gray screen of death after about 20 minutes use. Have not had time for further tests on B yet.
    Back to my saga with A (my original iMac G5 that was working fine with 1GB stick on 10.5.7):
    Called Data Memory Systems and they sent me a replacement for the 'bad' 1GB stick.
    While I was waiting for the new 1GB stick from DMS, I was struggling to get machine fully updated. Software Updater was failing with the weird network error (network was fine) and after following steps to troubleshoot, I backed up the user accounts and decided to reinstall OS X fresh from the 10.5.6 retail box (family license). Finally, I had OS X 10.5.8 all fully updated on the 1GB iMac G5 (A).
    New memory arrived, installed 2nd 1GB stick. Booted up, immediately I got the gray screen of death. Restarted, booted up got about 5-15 minutes use then gray screen of death. Puzzled, I called DMS who said unlikely I got 2 bad sticks. They suggested I try memtest. So I did...
    So on A, I first ran memtest from single user mode on the 2GB config. It crashed immediately with some 'Unexpected' error. Did not look like a memory error. I powered down, removed 2nd 1GB stick, and ran memtest from single user on the 1GB stick. Ran all tests 3x over a couple hours - no problems found. Retested after swapping the 1GB stick for the other. Both tested fine. Installed both sticks again and ran memtest all tests, one pass (didn't want another 6 hours lost) on the 2GB config, and all tests passed. Booted up and got gray screen of death - I don't recall if it was on bootup or after running but I ran fsck with no disk problems found, then restarted, logged in, ran disk utility to repair all permissions. Some repairs were made. Restarted A, reset PRAM and NVRAM again, booted successfully.
    I haven't had much time to run extensively apps on A yet. It's sleeping as I type this on another mac. My next test will be to reset SMU.
    I'm starting to wonder if the original iMac G5 has firmware problems that would prevent it from being unstable with two 1GB sticks??? My experience on two identical models of iMac G5 plus reading this post with VERY similar behaviors and after all the normal tests. I've concluded the memory is A-OK and something more sinister is lurking...
    Any thoughts are appreciated.

  • Problems with RAM Upgrade

    Hi,
    I work in a school with 204 slot loading iMacs. They are G3/450 DV machines running OS 9.2.2. They all had 2 65 meg RAM sticks. We took one 64 out and put a 256 meg RAM stick in each. Most of them responded well to the upgrade, but about 40 of them now refuse to start up. We thought it might be the battery so we tried putting a new battery in one of them, but that didn't help. We tried replacing the RAM, but that didn't help either. The only thing that works is putting the original 64 meg RAM stick back in the computer. Can anyone help?
    Sincerely,
    Jim

    Check the plug connection on the back of the iMac as well as the wall socket connection. Make sure both are firmly in place.
    Except for the keyboard & mouse disconnect all devices from your computer.

  • Problems with auto upgrade Anyconnect 3.1

    Hello,
    I'm having problem with auto upgrade of Anyconnect 2.5 to 3.1.
    Here is the situation :
    I have ASA5510 running ASA 8.4.5 and clients are running Anyconnect 2.5.3055 and 3.1.00495 with 2 different profiles.
    Clients with 2.5 can upgrade to 3.1 but then receive an "Invalid host entry" when they try to connect with new client. It works if they use FQDN instead of profiles. It's the same situation with Windows 7, Mac OS X and linux.
    If I configure client software back to 2.5 on ASA, it works again for every client.
    Do you have an idea ?
    Thanks for your reply.
    Yann

    I have seen the same behavior on Mac OS X. A couple of points for me:
    If I delete the profiles from /opt/cisco/anyconnect/profile then I can connect once (using the FQDN) but it then downloads the client profile and on next attempted connection it receives "invalid host entry." My profiles use the FQDN of my ASA and both forward and reverse DNS resolution are configured properly.
    My workaround is to remove the AnyConnect Client Profile entirely, but I can get away with that because I have a very simple setup, with all users in one default group. If I had to pass different profile information to different users that would not be a solution.
    Second, better workaround: I just exported the client profile, imported it under a different name, edited the new client profile to remove the server address, and assigned the new profile to the group policy. At their next login, users get all the profile settings and since the client remembers the FQDN they used to connect it doesn't adversely affect the user experience.

    #1 Do a complete bootable backup of your drive before upgrading. That way should anything happen you can revert back to the start and try again.
    Make sure you meet Snow Leopard 10.6 Technical Requirements - http://support.apple.com/kb/SP575

  • MSI P6N SLI PLATINIUM problem with ram 800MHz

    Hello.
    I have problem with ram frequency.
    I have MSI P6N SLI PLATINIUM and OCZ 2x2GB 800MHz CL5  but in bios I see that my ram runs in 667 MHz. Because I have 800MHz ram, so it shouldn't be default 800MHz and not 667MHz? What I have to do to show bios that I have 800MHz ram?

    Quote from: DaLoona
    Oke, but they told me when i bought my new system that XP auto adjusts the speed of the memory.
    XP 64 bit can works normally with 4 or more GB they said, just like vista.
    Just typing what "the professional's" at the store said.

  • Problems with Mavericks upgrade?

    Thinking about uprgrading to Mavericks, but have been coming across a lot of threads/reviews about people losing date and/or having real problems with the process. It's been a while since I've been here, and just wanted to ask for an opinion/advice.  I'm using Snow Leopard 10.6.8.  Should I stay away from it, or if I do, what advice/tips do you have for a smooth upgrade?
    OR -- is it possible to get Mountian Lion Somewhere?  I looked for it in the app store, but couldn't find it.  I heard some negative reviews about Lion, so I just kept Snow Leopard, rather than take any chances with a new OS.

    Mavericks is excellent on my MBP 8,2. Fast and flawless. Faster than Mountain Lion.
    New features I like: iBooks, iCloud keychain, enhanced dictation.
    A few things to consider:
    Any new OS has some bugs and incompatibilities with old software and hardware. If you are uncomfortable with basic Mac troubleshooting, then perhaps waiting would be a better strategy. I didn't have any problems, with installation or after.
    If you have any mission-critical software or peripherals, make sure they are compatible first. Check your apps for compatability here: RoaringApps - Application compatibility and feature support for OS X and iOS
    Mavericks does not play well with some old/bad software and hardware:
    Crapware: anything that purports to "clean", "monitor", "protect", or "accelerate"  your mac. Unnecessary on Macs and often harmful. Examples: CleanMyMac and MacKeeper (the King of Crapware).
    antivirus software. Unnecessary on Macs.
    WD hard drives.
    Before you install Mavericks:
    backup your old system, either with Time Machine, or better yet, a bootable backup.
    have enough RAM. The specs say 2GB, but 4 is probably a more realistic minimum.
    uninstall Crapware, antivirus software, and any other junk you don't need.
    repair your hard drive and permissions with Disk Utility
    boot into safe mode, and then run the installer Mac OS X: What is Safe Boot, Safe Mode?

    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?

  • Terms that void apple care with RAM upgrade

    Hi,
    I want to upgrade the RAM of my macbook to at least 1gb. I have heard some conditions that may void the apple care that I bought. So, I heard that you would have to leave at least one of the original RAM cards in there for the warranty to still be considered good? Is that true? And if that is try is it bad to mix a 1gb RAM card with a 256mb or is there a difference, or is it better to just get 2 512mb? thanks.

    Welcome to the Apple Discussions!
    The RAM of a MacBook is considered a "user installable part" by Apple. You will not void your warranty by replacing the RAM. However, if you damage something in the course of changing the RAM, the repair will not be covered by the warranty or AppleCare Protection Plan. Here is Apple's article about this:
    http://docs.info.apple.com/article.html?artnum=25097
    Apple will even give you instructions on how to change the RAM:
    http://docs.info.apple.com/article.html?artnum=303721
    Because of the graphics sub-system installed in your MacBook, there is a benefit to using matched pairs of RAM. How much this will impact your user experience will depend on how you use the computer. Personally, I would recommend you keep the RAM in pairs, but others here have had no noticeable problems with unmatched capacities of RAM.

  • Reset-nvram, reset-all necessary with RAM upgrade/EFI?

    When you upgraded or downgraded ram with the ppc architecture it was always best practice to reset-nvram, reset-all within open firmware. I've gone through apple's documentation and done a little research on the internets and can't find out if this is still necessary.
    Since intel macs are using EFI instead of Openfirmware, is this no longer necessary?

    Thanks for the reply. Just installed 2gb (2x 1gb transcend sticks)
    So far so good:
    1.83ghz, wifi, bt, dashboard widgets off, no apps running
    Xbench @ 512mb = 48.31 on batt, 'normal'
    Xbench @ 512mb = 45.18 on AC, 'best performance'
    Xbench @ 512mb = 60.29 on batt, 'normal'
    Xbench @ 2gb = 59.09 on AC, 'best performance'
    Apple System Profiler reports that both transcend sticks are running @667mhz, which was a problem with patriot mem.
    The 2x256mb sticks I pulled out were hynix mem: HYMP532S64BP6-Y5 AB, I was surprised. I thought apple used samsung for these macbooks.

  • 3 beeps with ram upgrade

    My Macbook beeps after installing ram upgrade. Doesn't matter what maker. I know that all the specs are right but I keep getting the 3 beeps to indicate the banks are empty, not that it's incompatible RAM type. What do I do now?

    When I put the old memory cards back in, it starts but only showing half the RAM. When I switch positions (slots) for the cards, the empty banks also switch positions so that seems to indicate a problem with one of the original cards now also. Am currently the hardware test. Just done in record time, "no trouble found." However, profile is showing only half the RAM actually installed.

  • Problems with Vista upgrade on Moduslink

    'COA invalid', 'Irrecoverable Error', 'Alert not Implemented'... these are kind of messages I get from Moduslink. I'm not expecting to reply my emails since they are in neck-deep.
    I love my A100 SAA9E, a very stable and powerful machine. I'm from London and have selected all the right options, but it would either come up with a random COA prob, or an error after my penultimate step.
    What can I do? Help.
    Shawn

    I was unable to complete the Vista upgrade via the Moduslink on Toshiba's website http://wwww.toshiba-europe.com/vista-upgrade, even though I got to paying for the upgrade with my credit card. When my payment was being processed I got an 'unrecoverable error', so I went back to repeat the process and this time the site didn't recognize my COA on the bottom of the laptop.
    I contacted Moduslink via the following Tel No. 00800 666 44 666 (UK) and spoke to one of their support staff (choose options 5 and then 8). There is a problem with their site excepting payments from credit or debit cards. The representative reset my COA, but it takes 48 hours for it to clear (so much from electronic data communications to servers). I have been told to retry the upgrade process again on Friday 16/02/2007, however, this time to pay either by wireless transfer from my bank or send a cheque.
    Hopefully, this will help others who were frustrated with the Vista upgrade debacle. It would be more appropriate however, if the company concerned, Modulink, resolved the issue in the 1st place. Firstly by informing their customers that there was an issue, secondly on a work around to the problem and finally fixing the problem. Will commonsense ever prevail?

  • I could not see how to continue after upgrade to firefox 4. This has never been a problem with ast upgrades. I am finding Firefox to be very user unfriendly for non-tech people.

    I am being told that my current version of firefox is no longer protected. When I tried to upgrade to firefox 4 some time ago, the menu bar(?) was gone--no bookmarks. I set my computer back to an earlier date to get my book marks back and have been afraid to attempt this upgrade again. Firefox also appears to have tried to do the upgrade automatically and says I have incompatible add-ons. I have never had problems with previous updates. I have read negative reviews of firefox 4 and am frankly afraid of it. I hate to leave firefox and am afraid of losing my book marks as well. I find the "Help" forums etc. here extremely difficult to navigate and they seem to be aimed at people who are more tech savy than many of us are.

    #Firefox 3.5.19 which you are using is no longer supported and is not being updated for any issues, including security problems.
    #The Menu Bar (File, Edit, View, History, Bookmarks, Tools, Help) was replaced in Firefox 4 by the "Firefox button" in the upper left corner
    #*You can turn the Menu Bar back on by doing one of the following in Firefox 4:
    #**click Firefox button, click Options, click Menu Bar to select it
    #**HOLD down the ALT key while pressing the keyboard letters VTM
    #**right-click on an empty space in the Navigation Toolbar, then click Menu Bar to select it.
    #Some information about Firefox 4 changes:
    #*https://www.mozilla.com/en-US/firefox/features/
    #*there is a link "watch the video" under '''''Improved Interface''''' on the above page
    #You can make Firefox 4 look more like prior versions: http://www.computertechtips.net/64/make-firefox-4-look-like-ff-3-6/
    Your bookmarks should be safe during the upgrade; they are in a separate place on your hard drive. You should keep them backed-up in case of any problems with your system. See:

  • Problem with PRD upgrade from 4.6C to ECC 6.0

    Hello,
    I'm experiencing a problem with our live Productive system, and hoping for some ideas on how to resolve.  First, we have successfully upgraded our DEV and QA environment, and are now upgrading PRD.  I was successful in getting through the uptime SAPup of our downtime minimized upgrade.  Note that I did not need to log into the Shadow instance at all, because all modifications will be transported from DEV during downtime.
    However, I did want to log into the Shadow instance to take a look at it.  I first had to start the instance in the SAP Management console, and then when I attempted to access via the SAPGUI, I recieved error "Internal TSKH error.  Session terminated".  Also, I noticed that as soon as I started up the Shadow instance, I am now getting "SYSTEM_CANT_CLEAR" short dumps every minute.  Error says:  Error when initializing the work area "SYST".
    Since I don't need to log into the Shadow instance to complete the upgrade, I'm not sure if this is going to be an issue for me or not while I complete the upgrade.
    Any assistance would be greatly appreciated.
    Thank you,

  • TS1717 are there problems with iTunes upgrading from Vista to Windows 7?

    are ther problems upgrading iTunes from Vista to Windows 7?

    The best method is to use Windows Easy Transfer first to backup all your data, and do custom clean install. And install all your apps and drivers afterwards.
    Yes it should work. Make sure you are ready, and have all the latest drivers and applications ahead of time.
    There are some "gottchas" with the upgrade from Vista.
