    I get this error message after the Test run of equipment due to a problem with loading the images/graphics.  27 "iMAC, end 2012, 16 GB of RAM installed Apple.  Replaced RAM with two Modules of 8 GB of OWC/Mac sales and still got the error with the exception of the code backward colon.  An increase of RAM with two additional Modules of 8 GB also of OWC.   Still having the same problem with the loading of graphics.  I was wondering if this could be related to a problem on the motherboard.  Only 4 months on my warranty of three years total. Any help will be greatly appreciated.

    Memory of AHT test will report a failure when a read memory value differs from the value written to it. In almost all cases which will be due to faulty RAM or RAM that do not meet the specifications required. The logic board failure you think is another, although rare, possibility.

    The value after the colon is the specific address of the failure of R/W. Its meaning is not important.

  • Apple Hardware Test error 4SNS/1/40000000: VC0C-1, 519

    My Macbook Pro Core 2 Duo 2.53 13 "MID2009 (4 GB RAM, 320 GB HD) looks like her work until I play any music.

    When I play any kind of music MP3 or MP4 Player, his plays fine, but after awhile, it starts to hang. I played in iTunes think its iTunes may be the cause. So I downloaded VLC player and it does the same thing. So I thought that maybe the file is corrupted so I copied it on an another MacbookPro and it plays normal without getting stuck / hanging. So I formatted my HARD drive and installed in El Capitan, but it was not a solution. I get the music GET think even stuck/hanging.

    I have run the Apple Hardware Test and got the error 4SNS/1/40000000: VC0C-1, 519.

    I'm trying to find what this error means, but can't find it anywhere on Apple not the Web.

    Y at - it that someone here can tell me what is the cause? What is memory? hard drive? or what?

    Anyone has this experience or obtained a solution for me? What should I do?

  • AHT inconsequential error Ram 4MEM (Mac Pro 4.1)

    Hi all.

    Something weird going on here. Evil Finder behave sometimes (especially with the readers of WebDAV connected cloud/external) and Photoshop don't... Well well... strange things. So I thought I would check my material with AHT.

    I have a Mac Pro 4.1 / 2.93 GHz Quad with 24 GB of RAM: 2 x 4 and 2 x 8 GB. AHT reports a RAM error (4MEM). So I removed all the DIMMS and test began with the two 4 GB ones and AHT returned an error (4MEM) RAM. When I test both 4 GB modules in AHT 1 and 2 housing reports and a mistake. When I test a single module of 4 GB in slot 1 or 2, I get no error 4MEM. So the two modules installed together DIMMS = error. Installed individually don't = "no found prolems.

    In addition, 4MEM errors seem incompatible:

    65/4MEM/40000006: 0X799D7C18

    9/4MEM/40000006: 0X799D2998

    Then, I tested all of the 24 GB of RAM with MemTest86 CD but he could not find any problems.

    Someone has an idea, what happens?

    It would be really good if, when an error has been detected, memory modules would all just dropping dead, problems would be easy to isolate. But this isn't the case. Memory problems are difficult to find, they come and go, it is very difficult to 'catch them in the Act. Synthetic patterns of tests memory do not always generate the same failure that made a running system.

    But your money Mac Pro tower with processor Xeon processor uses memory RAM of code of error correction. Modules of memory have eight extra in addition to the 64 data bits control bits, as well as your Xeon processor use on all references to memory.

    On writing, permutations of parity on the subsets manufactured with care the data bits are stored in the extra bits '' syndrome. '' On reading, a lot of correction and error detection can occur. Mistakes single-bit are detected and hardware corrects these errors in tense cycle of memory, without any software intervention. Error indicators are read from time to time in the background, and the results are recorded by the memory module.

    Generally, a benarde error cannot be corrected, so to design this cause your Mac to stop during a panic machine control, core, often detected by multiple processors to prevent the poisoning of your data.

    Errors counters can be read by the memory of the about this Mac report:

    chart de.com

    your report will be slightly different, but the information it presents is STATIC - for updated information, you must refresh the report or call it again.

    Many tests memory of third parties are not designed to run on a Mac with memory error correction. As simple mistakes are corrected in Hardware on-the-fly, they aren't.

    In addition, the error correction is used very aggressively at the start. The reasoning is that the nay errors that occur in these seconds must be so severe that the modules must not be used by the system, and their locations will be marked "void".

    Any module that is seen as BAD in any situation is really BAD, even if they suffer later. If your Mac was overheating for a different reason, which may explain why the modules tested bad is perhaps the only excuse. If you eliminate overheating, these modules may be ok later.

  • MacBook Pro (retina, mid-2012) Apple Hardware Test 4MEM/9 error code / 40000000:0x794a4390

    The first AHT I ran gave me the code of error 4MEM/9 / 40000000:0x79456d90.  I shut down the computer as suggested and then re run AHT and received the error code 4MEM/9 / 40000000:0x794a4390.  The two tests have been extended to tests.  Is that going to be an expensive repair?

    Thank you

    The error indicates that there is a RAM problem.  Since you have a MBP of the retina, the only alternative you have is to take the MBP for an Apple store genius bar.  (RAM is welded in a MBP of the retina and is not accessible to the user)  The assessment will be FREE and they will advise you of all the costs involved.

  • Work very well iMac 27 mid-2011 with 4MEM error code

    Hi, I have an iMac 27 inches, mid-2011 with 4 GB installed original (Elpida so-DIMM) so I improve it with 4 new 4 GB Kingston (ram value) KVR1333 PC3-10600 1333 Mhz DDR3 DIMMS for a total of 16 GB, after that my iMac works very well for three years with the daily use of any question and everything seems normal in "about this Mac" and in the "memory" tab no software issues no kernel panic , anything with a strange behavior, until three years after the upgrade memory, now I run AHT because the other reason (I can't work with a new MBP Mid 2012 airdrop both with El Capitan OS X) and it shows me a 64/4MEM/40000000: 0x8893cb98 error code, I reset the NVRAM and SMC, and same result AHT , so use MemTest86 from a V6.3.0 of bootable CD (full test upward at the end time spent 23 hours) and V4.3.7 showing no error in the two tests, also I ran mdsched.exe RAM Memory Sticks Checker windows (I have Windows 7 64 bit family Premium installed in bootcamp) and no ram detected error.

    While I should care that error? should I change my Ram modules?

    Thanks in advance

    You have a faulty memory card or the slot. That's what the error means generally. Make an appointment with the Apple Genius Bar for the service. If you need a Apple Store - find a store - Apple.

  • Mid 2012 MacBook pro test equipment

    I got the error 4BAT/1/40000000: 0x8984fb90 while doing the test hardware. Can anyone advise if this is a question of logic board or battery? I checked in the coconut battery test and battery seems fine. I had this problem all of a sudden as I was getting backup from 2-3 hours, but all of a sudden, it worked only when power adapter connected. I checked using different power adapt too and also tried to remove the battery (it was working fine when connected). Any clue? If it's a question of logic board then I better start my computer or notebook.

    go to  > about this Mac > report on the system >

    and select the power

    include a screenshot of the results and remove any personal information like Serial #'s.

  • Why is my MacBook Pro screen green pixels

    My pixels of the screen are green when I wake the computer if it has been asleep for a long period of time, like all night, or for several hours during the day.  If I keep it for a while, he begins to fade, and the screen appears quite normal, with sometimes flickering. It seems almost as if the screen, or the computer, it must warm that he go away.  I'm afraid that my computer is telling me something serious. Like, you need to replace this computer immediately!

  • Kernel Panic in OSX but not Windows (Bootcamp)

    I have a 15-inch MacBook Pro (early 2011) which has recently experienced sudden stops and the kernel panics. Panic report always comes out:

    panic (the appellant 2 cpu 0xfffffff7f8d8ae4e6): "MCO GPU REGISTRY RESTORE FAILED: rdar://7254528, VendorID invalid"@/Library/Cahes/com.apple.xbs/Sources/AppleGraphicsControl/AppleGraphic sControl-3.11.33.1/src/AppleMuxControl/kext/AGCPowerManagement.cpp:1158.

    ....

    ....

    Here is what I have done so far:

    -Went to the Apple Store for the MacBook Pro video problem Extension program repair (it goes the diagnosis made here)

    -Ran an Apple Hardware Test (error 4HDD/11/40000000: SATA (0,0)) and repair of disk utility (no problem found)

    -Re-installed backup Time Machine but still experienced kernel panics

    -Erase the Mac partition and made a new installation of OSX but panic kernel continue to hamper

    ^ - After completing these steps I suppose now that it is not a problem related to the software/OS, so I thought it must be a hardware problem. The strange thing is that Windows 10 on my Bootcamp partition still works and has no problem. I don't know if I'm missing something, but if it was a hardware problem (hard drive, SATA cable, RAM, logical card) so shouldn't the Windows partition also have problems?

    Please let me know if you have ideas or suggestions. I'm stuck with Windows help in the meantime.

    When the Apple Hardware Test results by generating an error code, there is a hardware problem.  The error you posted indicates a problem connecting to the HARD drive.

    It might be useful if you have published the report of whole kernel panic.

  • Help! I got this error 4MEM/62/40000000: 0x7f532190

    Hello world! Sorry to panic but I just got this error 4MEM/62/40000000: 0x7f532190 is that bad?

    Thank you!

    This means that the test identified faulty memory, replace the memory.

    You will have to perhaps remove some memory and rerun the test to find the defective stick
