Apple hardware test results means?

My older 20" imac intel crashes 1-4 times a day, freezes up, have to press power button to shut it down; ran apple hardware test twice and got these two alerts: apple hardware test 4MHD/2/40000004: 0x7c651f10     and   4MHD/2/40000004: 0x7ba72510;  before running AHT, had already run diskwarrior, disk utility, TTPro, and they all found nothing amiss.
any ideas? much thanks.

I don't know what the errors mean but the symptoms could point to the memory. You've tried everything else how about removing one memory module at a time and rebooting to see if you can eliminate that possibility.
Good luck, Rick.

  • Anyone Know what this apple hardware test error means?

    Hi I've been experiencing some problems with my mac it gets to hot fans nerver go up not even with smc fan control installed and some times it freezes so i decided to run the apple hardware test that comes with the machine and during the memory part it showed me this error code
    4MOT/1/40000003:HDD
    Does any one know what this means or have any idea with what part of the machine it can be related to
    Thanks hope sombody answers

    If I had a hardware error detected by Apple Hardware Test (which in my experience misses the minor things) then I would be raising a case with AppleCare right away.

    You shouldn't have to deal with hardware failures on a Mac this young.

  • Apple hardware test result

    My macbook pro keeps crashing. - black screen with an instuction to restart. I run the Apple hard ware test and it gave me this error code:

    Hello!
    I had the same problem and solved it. Please refer to the link below.

    This is a bad memory DIMM problem. You need to trace which one of the DIMMs is defect.
    The problem can appear spontaneous (as it was on my MBP). Once you got this error code, try to make memory test.
    There is very helpful program for memory test under Mac OS X. You can find it here http://www.memtestosx.org/

  • Question on Apple Hardware Test Results

    I just ran an extensive test on my MacBook Pro (Late 2012). I got back the reference code 4MEM/66/40000000:0x7f562590.
    I can't find what that means. I am assuming it is a memory issue. Safari has been locking up on me quite a bit, as well as Finder. Everything seems to be a task with my computer as of late.
    If anybody could give me a direction, I would appreciate it.

    The MEM part of the code usually refers to memory modules so i would say that one or both of your RAM modules are defective.If your machine is still covered by a warranty, contact Apple. If not, book an appointment at your nearest Genius Bar for a definite diagnosis. If it is the RAM and yours is a 2012, I believe that is the last model where the RAM is user replaceable, so you could easily do it yourself. Make sure you get it from a recommended vendor such as OWC (macsales.com) or Crucial.

  • What does the error from my Apple Hardware Test mean?

    I was doing some maintenance on my iMac G5 (Ambient Light Sensor) this past week and found that my Video RAM might be bad.
    My first clue was that when I used the 'option' key on boot, one of the resulting screens was covered with vertical lines of about 1/16 of an inch.
    My second clue was that after running the Apple Hardware Tests, iMac Version 2.5.1 (the one that came with my iMac's original 10.4 Tiger installation disks), I was told there was a Video RAM error, but am not sure if I copied it right because all the little vertical lines. Here is what the AHT reported:
    ** ERROR ** ** ERROR ** ** ERROR **
    2ATI/1/4 113-xxxxx-117
    ** ERROR ** ** ERROR ** ** ERROR **
    Does anyone know what all this means? When I run OS X my desktop doesn't appear to have any video problems, so I was taken be surprise.
    Thanks.

    Well I just wanted to chime in I know this is a little late, but I just picked up a iMac G5 for $50 that had this same problem, I would recommend you take the back cover off of the iMac and inspect the capacitors, I did and found a blown capacitor I took the logic board out took it to a local PC repair shop and for $35 he replaced the blown cap. They don't have to be completely blown to mess things up just domed or really anything other than flat. I came home put it back together and everything works great. just something to consider I mean for 30-50 bucks what could it hurt otherwise if no blown caps are visible then your video chip needs to be reseated and I don't know what to tell you on that.

  • Apple Hardware Test (MacPro) result codes

    Hello, My MacPro has been doing the wierdest things like freezing up, although the mouse will move. Freezes while monitors are sleeping. Freezes when I move mouse towards dock. Freezes for no apparent reason ... all updates have been performed.
    Bright idea tonight, I decided to run the Apple Hardware Test provided on my install disks ... I got an error code "4SNS/1/40000001:VMBS". No idea what it is or means and have searched high and low on the internet for result codes.
    Does anyone know what this means?
    I have been supicious of my ATi Radeon X1900 XT for some time as there have been artifacts and odd colour shifts and graphic anomalies.
    Thanks for your help, all is appreciated.

    apple hasn't released a key to the public as to what the hardware codes mean.  you really need to take it in for diagnosis.

    You can buy and install the hard drive you want to. However, on Late 2009 and newer iMacs the temperature sensor is in the hard drive, so if you replace it with a hard drive that has not got a temperature sensor you will have serious fan problems.
    You have got an Early 2009 iMac, so do not worry about this. You can buy a hard drive at OWC > http://eshop.macsales.com/shop/hard-drives/3.5-SerialATA/ Follow these steps > http://www.ifixit.com/Guide/iMac+Intel+24-Inch+EMC+2267+Hard+Drive+Replacement/9 028

  • HT201257 mac os x 10.4.11 tiger: apple hardware test has detected an error (what does this mean): 4SNS/1/40000001:VDOR

    Can someone help?  I did an apple hardware test and it has detected an error:  4SNS/1/40000001:VDOR
    What does that mean? Can i correct it myself? how?
    my computer is  "tiger" mac os x 10.4.11, Processor: 2.16 GHz Intel Core 2 Duo,  Memory: 2.5 Go 667 MHz DDR2 SDRAM

    Thank's for answering, realy appreciate your time,
    A technician had installed last year "mac os x snow leopard 10.6" (family pack) at around $49.00 - I had originaly mac os x 10.4.11 (tiger).  He had changed my hard drive, added memory: 2.5 Go 667 MHz DDR2 SDRAM, processor is: 2.16 GHz Intel Core 2 Duo  (he told me he had to change my hard drive probably due to a power shortage. Before he did the changes, I had done a hardware test: it gave me the same error as today 4SNS/1/40000001:DVOR,  He cleaned the inside, but he did not change any sensors. What am i to do???
    Not too long ago i started having problems. (probably from a power shortage, at one point.  I don't know if my external back up got corrupt. so i don't want to use it. He had eraced tiger 10.4.11 and installed snow leopard 10.6.
    I eraced snow leopard and installed mac os x 10.4.11 (that came with my computer).  
    I wanted to install mac os x 10.6 (snow Leopard) without eracing tiger (chat sites say you can do that) but it said it couldn't use my hard disk because of my memory:  my info says: used: 18,78 Go on the disk, available: 446.66 Go, Capacity: 465,44 Go
    So that's when i did a hardware test with the CD1 of mac os x 10.4 (tiger) and that where i got the message.
    If i have a sensor problem, then i guess i'm waisting my time trying to reinstall mac os x 10.6 (snow Leopard) or am i doing it wrong.  I was told i could leave tiger there and upgrade directly to snow leopard, without installing mac os x 10.5 (leopard).  
    Thank again

  • Apple hardware test..i dont know what this message means..please help!!

    hi all..i really need your help. i have been having serious problems with my g4. it has been telling me to restart it while using most of the programs that come with installation. sometimes black lines with wording comes across the screen forcing me to shut it down. now all the programs are quitting one right after the other. i have reinstalled the system. i have no added memory installed...jsut the 256mb standard. tonight i ran an apple hardware test and i got this message. "memory- error detected error code 2mem/3/4:dimmo/built in" what does this mean? do i need more memory and if so where do i get this? thanks so much!

    Based on that information the built in RAM has failed. What you have been seeing is a Kernel Panic. Sadly since it is the built in RAM, adding more memory wont help, not that you cannot doing it, but I don't think it will stop the Kernel Panics. Bad RAM causes OSX problems, namely Kernel Panics so until the problem with the built in RAM is dealt with this will continue to take place. Being built in RAM, that means you'll most likely need a new logicboard. You will have to get your machine repaired if you wish to continue using it.

  • What does Apple Hardware Test error code 4MEM/1/40000000:OX3bb6b190 mean?

    Mozilla kept crashing so I did the Apple Hardware Test and got error code 4MEM/1/40000000:OX3bb6b190. I reinstalled MacOs 10.4.4 (after saving the important stuff to disk of course) and it took about 10 tries to get the 2 disks installed. After the installation, I tried to update to 10.4.5, and when I restarted, the screen was blank. The only disk the computer will start with now is the No. 1 installation disk. What can I do?

    Hi
    A MEM error code generally indicates a faulty RAM Module. In my experience most RAM manufacturers offer at least a 5 year warranty of their RAM products. Some warranties are for 10 years. Sometimes reseating (taking it out and putting it back in again - properly) the Module will 'cure' the problem. Run AHT afterwards if you try this option first.
    If you can remove the offending module and still have enough RAM to be able to do what you need to do then do so.
    If not take it to your nearest Apple Repair Specialist who should fix it for you or replace the faulty module yourself and deal with the RAM manufacturer directly.
    Judging by the footer to your post you don't seem to have had much luck with this model have you?

  • Will Apple Hardware Test definitely detect RAM errors?

    Hello,
    Been having various problems with Leopard/MacBook. Someone suggested running Apple Hardware Test, which I did, in extended + looping mode all night (it cycled 6 times). The test turned up nothing. Can I take this to mean that whatever problems I am having are definitely software related? I am not familiar with the AHT, don't know exactly what it does, nor how I can interpret a "clean" result...
    Many thanks for any advice/tips.

    No indeed (just "Colin" is fine...)
    My problems have mostly been documented by other people, and I have just been monitoring the discussions on these issues.
    Specifically (at the risk of getting off-topic):
    1) inconsistent shared server behaviour: I have 3 other macs at home - an iBook and a G4 MiniMac running Tiger, and a G4 tower, also running Leopard - and most of the time, the tower doesn't show up at all, but I can connect to it via CMD-K, the MiniMac shows up in the sidebar, but won't let me connect, and the iBook, when it is running, behaves normally. Oh, screen sharing doesn't work either: it tries connect but hangs (except for the iBook, which works). I could connect to all four quite normally after upgrading to 10.5.0, using the sidebar icons. Everything worked fine until sometime after the 10.5.1 update, when suddenly everything went pear-shaped. Nothing has changed in the configs of the other machines, and the iBook and the MiniMac are identical in terms of software config (but behave differently as regards this problem?!?)
    Closing Airport and reopening it makes the icons reappear in the sidebar (all of them, G4 tower included), as does relaunching the Finder, but doesn't change the behaviour: I still can't connect. When I try to use the sidebar icon for the tower, it disappears (the icon...)
    As far as I can tell, trying to operate shares from the G4 tower works as Apple intended (although I admit I have not exhaustively tested every option, as I don't have unlimited time...)
    2) Lost my printer connections, both at work and at home. I managed to reestablish them at work, but I tried so many things that finally I'm not sure what actually worked. No dice at home (shared printer on the MiniMac... same problem as (1) I guess.)
    3) the dreaded Keynote spontaneous reboot problem (I placed a reply about that last night here:
    http://discussions.apple.com/message.jspa?messageID=6630702#6630702
    4) diverse weird things, like
    4a)iCal which had doubled all my events the last time I opened it. I had to manually delete one copy of every event I had entered, whereas I made these entries several weeks ago, and had consulted them many times... I'm thinking this is perhaps a result of the brutal reboots caused by (3)? Having deleted all the doubles, iCal seems to be behaving normally again.
    4b)screen resolutions on my slave screen suddenly failing to select properly. I move my MacBook between two different external monitors, one at work, one at home, and their resolutions are different. Initially the MacBook had no trouble detecting and correctly setting the resolutions for the two screens, then suddenly my home screen went weird on me, and required a manual reset. Again, this was a once-off, and does not seem to be repeating (yet).
    4c)sluggish performance with some apps that are normally quite snappy, like Firefox, which seems to hang a lot loading pages, Keynote (saving is often painfully slow), and indeed, trying to copy a 250Mb file from the tower to the MacBook via Airport (having connected using CMD-K) said it was going to take 33 hrs, which I thought was a bit rich...
    4d) hot-swapping a usb pin for a keyboard+optical mouse receiver from the tower to the MacBook sometimes causes something inexplicable to happen to the MacBook's keyboard: both the Caps and the NumLock LEDs come on, and the keyboard has jumped into some config other than what it is normally in (French). I have not been able to determine what the keyboard actually thinks it is when this occurs (3 times now). The command keys (ctrl, alt, cmd) do not appear to work at all. Rebooting corrects it.
    All up, pretty irritating, and a huge time waster, as you can well imagine. I stuck a bit of a rant on the discussions the other day in a moment of intense frustration, which got zapped by the moderators (probably not unreasonably!), but not before someone replied suggesting that it might be bad RAM, hence my questions here.

  • What do Apple Hardware Test Error Codes indicate?

    I recently installed new 1GB memory modules in both slots. When running the Apple Hardware Test, I got the following error code:
    post/0/2048 S0DIMM0/J20STANDARD
    Does anybody knows what this means? Up in the Test Results Box, it said Memory passed.
    Do I have a problem or not?

    I've had little luck finding a compilation of those AHT codes and their meaning. In your case, "post" is probably "power-on self test," the routine that all Macs run at startup to check for problems.
    2048 is the total RAM qty in MB.
    J20STANDARD is the logical name of one of the RAM slots.
    Run System Profiler and see what it shows for when you select "Memory" from the left-hand pane. On my 1Ghz 17" PowerBook, Profiler shows one slot as J20STANDARD and the other as J23REVERSED and it runs fine. Profiler will tell you if the modules are matched for speed and CAS latency.

  • Run Apple Hardware Test  then show :4mem/61/400000000:0X816c3718

    I encounter the MacBookPro 13 MD101 issue that running Hardware Test . The result show the code :4mem/61/400000000:0X816c3718
    Is there anyone have know what's the problme about the meaning ? And how to deal with it .
    Wish someone can help me to solve the issue .
    Thank you .

    That usually means a problem with RAM - however I wouldn't bet a nickel on what the home-based Apple Hardware Test would report.
    If you want to really test your RAM, download and run Rember overnight. If any problems are reported, I would take the machine into your local Apple Store or an AASP and have them check it out using their more advanced test suites.
    Good luck,
    Clinton
