4MEM/61/40000000:0x82c54298

Hey,
I seem to have a problem with my ram. Is it possible to change the ram myself with this particular problem and does anyone recomemend a certain kind of brand for the RAM? (macbook pro, early 2011)

Yes.
http://support.apple.com/kb/ht1270
I bought RAM for my MacBook Pro 15 inch early 2011 from eshop.macsales.
Crucial is also equally good.

Best.

Same 4MEM/9/40000000 , but different aka (hopefully) the complete guide to this error code and changing RAM

Hello world,
finally, after having been reading here for years I decided to break silence and join the most venerable Apple discussions community!
First of all, I'm no native speaker, so if I at one point don't express myself correctly, I'm sorry. If you don't understand please ask what exactly I meant since it's very important that we know exactly what each one of us is talking about, thank you.
Important, too:
I know there are a lot of posts with this topic and I sifted through a lot of them but none of them captures exactly what my problem or rather my questions are and unfortunately in a lot of them there is no real feedback from the original poster how it all worked out or not. So, I intend this thread to be that one helpful thread which more or less concentrates the knowledge of the other threads, where people with similar problems can go to in future.
I ask one thing of you: Please DON'T answer with just one phrase à la "U got bad RAM, send it back" or "Contact Apple Customer Support Service whatever thingy" without explaining why this would be the only viable option (because I think it is not, at least at the moment).
All the questions I 'd like answered are green, for you to not lose track. I hope this becomes a good discussion so everyone of us can learn a lot!
Following problem:
Initial situation:
My Computer: MacBookPro 8.2, early 2011, 15", 2,2 GHz i7; Mavericks 10.9.5    (yet without this bash fix but ¯\_(ツ)_/¯ )
       - Upgraded RAM from onboard 4 (2 x 2) GB to the "unofficially" possible 16 (2 x 8) GB
Ordered RAM on Amazon.de with the right Specs: 204 pin DDR3 SO-DIMM (1333 MHz, PC3-10600S, CL9),
Manufacturer: CSX (http://www.csx-memory.com , while it's maybe not the most renown seller, it was described on another website as reliable )
    HERE (hope the link doesn't change):               http://www.amazon.de/gp/product/B0084SH6WA/ref=oh_aui_detailpage_o01_s00?ie=UTF8 &psc=1
       - Installed it, booted Mac without problem, what does System Profiler say? I have full 16 GB   1600 MHz   Memory installed
- Obviously sent me the "wrong" RAM (or can System Profiler be wrong??), funny thing: It works,
     --> after a LOT of research checked here http://guides.macrumors.com/Buying_RAM      my i7 is 2720QM, so supports it, lucky me
   Btw, if i go to About this Mac > more information > memory, the Text there even says it can hold 1600 MHz, has this been written there like this all along?!
- Which RAM do I have installed exactly now? since the sticker on it showed the originally ordered Specs.., moreover how do I determine the CAS latency of my installed RAM?
Crashes:
Didn't really have any, except..... well,
- In some instances Firefox (I think 32.02. or sth., the latest Version at this moment) reproduceably keeps crashing, for example right now, can't even start it, that's why I can't tell you the exact version, maybe I edit that later. Safari so far hasn't crashed.
- Once I had a System Crash, but it happened when I wanted to reboot after updating the firmware of a hooked on external WD drive to be usable again as time machine backup volume under mavericks (without endangering my data).
The RAM seems to work fine; for example when I was doing a long overdue backup of 77GB on said drive, Activity Monitor showed a RAM Usage of 15,99 GB and nothing crashed. Only the fans were powering at some point but i thought that normal..
- Actually produced two more Crashes when trying to run Apple Hardware Test (AHT), the one on the second disc that originally came with my Computer (probably made for OS 10.6.x    x= 6 or sth., don't remember which version my MBP was shipped with), which leads to
Tests:
Memtest86
- I put Memtest86 v.5.01 on a USB Stick and bootet from that and let it test "the whole" RAM
(btw Do you know how you can put the bootable USB image of Memtest only to one (of a few) partition of my 32 GB USB Stick? The instructions (command line stuff) only let me put it on the whole Stick which makes it otherwise useless as a volume; ok here I'm not sure if I'm using the correct technical terms....)
- I let Memtest86 do 3 and a half passes with one pass consisting of 10 different tests, so it took over 8 hours!
--> RESULT:   0   (in words: zero) ERRORS,
--> That is why I think my RAM is ok, because I think (think NB, don't know) Memtest86 does good testing,or do you know      better?
AHT
- After that, out of curiosity, I tried to run AHT from the DVD with said results, then I ran AHT (also called Apple Diagnostics under Mavericks) from the Internet, this worked, but produced the famous 4MEM/9/40000000 Error Code,
first one for example was: 4MEM/9/40000000: 0x8477df98, the last part after the colon is variable, but stays the same in one instance, i.e. if you repeat the AHT directly. If you restart the Computer an rerun the test then it changes, e.g. some other it showed 0x84770a18
- I did the short and the extended version, it took ca. 2-3 and 16 min respectively till producing the Error Code (only 1 at a time)
- Did it 4 times or so; once in short/simple version it showed no error, the rest the 4MEM/9 s.
some example of a simple test, results taken out of the System Profiler Window (fehlgeschlagen= failed):
Apple Diagnostics:
The usual self test on start up is always passed (bestanden), see for example:
What other than bad RAM can 4MEM/9/40000000 mean? I hope there are a few tech and computer savvy people around this place who know what they are talking about and can give me a good answer, or at least help to narrow it down. Actually I also think, the RAM sticks are not loose, but before I screw open my MBP again I would like to explore the other possibilities.
Is it probable that this Error Code has got sth. to do with me installing a) 16 GB of b) 1600 MHz RAM, or maybe with CAS Latency (i don't know the actual CL of this RAM)? and if so, is it only because some Apple Programmer/Developer/Technician wrote some values in a list on the System Level, so it doesn't accept RAM it would normally work with?? If it works fine and is faster, why change it?
Final Words:
I repeat, apart from the Firefox crashes, my Mac seems to be working fine, at least I don't notice anything, (well, that disk utility and System Profiler (or whatever it's called nowadays) sometimes take time to start up is nothing special i think, is it?)
But now I'm scared that perhaps there could be a future danger for my computer I do not foresee...I hope you can at least exclude that.
So I'd rather spend my time starting a discussion here with people who don't have to abide by some corporate policy (right?) than having the hassle of repeatedly screwing my Mac open and shut and doing expensive calls with all the companies involved who won't tell me anything more in depth than "we have to send it there, do more tests and you get it back then".
I hope that this thread won't rot in the wastelands of unanswered posts and that maybe all the people who take part in it learn sth. and all the people seeking help in future will find it here.
Thanks for your patience!
Waiting for your greatly appreciated answers,

PS: Why is there no category Hardware, Components, RAM or sth similar? Not sure if it fits in Ports and Interfaces so I put it under Using a MBP

Error 4MEM/9/40000000: 0x84e86298 ?

I have a macbook pro 17" Sn : C02G308GDF92 and I try to run Apple Hardware Test and comes error 4MEM/9/40000000: 0x84e86298. Anyone knows what's happening with my macbook ? Thanks.

That is a RAM issue. Take out the modules and clean the contacts. Then install therm and make certain that they are well seated.
If no success, download REMBER and run it overnight so that sufficient loops are executed.

This should determine if the modules are faulty or not.

Error installing OS then 4MEM/4/40000000: , does it mean bad RAM only ?

Long story short , while installing OS 10.4.10 combo update I got this message "there were errors installing your software , please restart your computer " , started up but would not get passed the login bar /blue screen , after numerous tries I started up from my cloned system , repaired permissions , verified disk (found problems and fixed them) , also booted up from original install DVD and checked the startup disk , showed all ok , still no luck , ran Techtool deluxe tests , everything passed , still no go, after various other atempts ( zapping PRam , starting in single user mode typing "reboot' etc.. ) without success I went for an archive and install from the original DVD , the installer stopped in the middle (there were errors installing...please restart) , same thing after writting zeroes to the disk and attempting a clean install , last I ran the Apple hardvare test which showed:" 4MEM/4/40000000: " (just that , no error code after 4MEM/4/40000000: ) , does it mean a RAM problem exclusively or could it be something else hardware related ? (I did tests using only one RAM chip at a time early on , did not seem to help) , I'd like to rule out the RAM before going to Apple (2GB third party RAM ).
Any help appreciated.

You'll have to ask an Apple Authorized Service Provider exactly what that error means, but it would seem to indicate a RAM problem. You could have a problem with the RAM slots themselves, not necessarily the RAM chips. But, chances are it's the RAM chips if everything was running before. It's possible that the software update revealed a problem that was not detected before. If you get the error with the Apple RAM, I would call AppleCare Support. If you get the error with your third party vendor, I would call them.

Macbook Pro shutting down. Hardware error code 4MEM/62/40000000:0x7f537f90

Macbook Pro shutting down. Not the same action making it shutdown. Anywhere from being online to attaching a photo to an email to working in Word or Photoshop. Even after it's closed and not being used. I come back to it being shut off and saying it had to restart because of a problem. I ran the Hardware check and got the Hardware error code 4MEM/62/40000000:0x7f537f90.
I must say I am quite disappointed. I have used Mac for work but had a PC since day one, and I JUST got this Macbook Pro in Dec. I was delighted that Mac usually didn't have as many problems with viruses etc as PC. And now last couple days, constantly shutting itself down. The closest store to me is a few hrs away. I am in South Dakota, store is in Minnesota Any help would be appreciated.

Can you post a screen shot of About This Mac -> (More Info) -> System Report -> Memory and click on each DIMM and post the bottom right pane. You can also do the same without a screen shot using just text version using the following highlighted command in OSX Terminal. The output is also listed.

4MEM/9/40000000: 0x8471a718 MacBook Pro late 2011 15"

Hello guys, i recently had some issues with my macbook, its been a month or two since i upgrade the ram of my mac from 4 gb to 16gb, and i didnt had any problems infact it's fast as never before. But now since i have update some apps and the software (by the way im running Mountain Lion) i have experienced some randomly restarts of my mac, most frequently when im using parallels 9.
I ran the hardware Test (alt + D) and after a couple of minutes this error came out.
4MEM/9/40000000: 0x8471a718
Macbook pro 15" late 2011 OSX 10.8.5
16gb RAM
Intel core i7 2.2 ghz
AMD 512mb video card
Dont know what this means and i'll apreciate any help.
Thanks
PS: Sorry any grammar errors if i had some Regards from Mexico

I just finished doing the things you told me, i cleaned the slots and the RAM chips and i test them individually and the error still showed up.
Next i tried installing the old chips (2gb chips) and i ran the test again and no problem was found. So i guess that maybe the problem indeed its the RAM i bought. I´ll contact the seller so i can solved this issue maybe i got a defective product, dont know.
Eventhough thanks for the help i was getting worried and hopeless but im glad you help me.
Regards!

Macbook Pro freezing (4MEM/66/40000000)

Hey,
I have a Macbook Pro 13" primo 2011. I've been having this issue with my Macbook where it freezes and beeps three times in an interval until I do a hard reboot. I searched at google, and it seems to be ram relatet, so I have installet Corsair Mac Memory - 2x8GB DDR3 1333MHz PC3-10600 and a new SSD harddrive, but I still have the problem. I did then make a hardware test and it gives me this error code:
4MEM/66/40000000: 0x830c5a18.
The code seems to be ram related, but I have aldreade changed my ram, so can the problem be my logic board?
Modelnavn:          MacBook Pro
Model-id:          MacBookPro8,1
Processornavn:          Intel Core i5

Boot ROM-version:          MBP81.0047.B27
SMC-version (system):          1.68f99

I had the same problem with my original 4GB (2x2) ram, thats way I in the first place replaced them with the 16GB (8x2) ram today. But unfortunately I had the same problem with the new ones. Thats why i thought it might be the logic board?
But I might have received some ram which was already destroyed. For when I came home from the store, I discovered that the package had already been opened. I have send them a mail and explained them that I want to return the package when I'm home from vacation.

Though it sounds a bit unfortunate I am experiencing the same error with the new RAM, as I do with the old ones. But I've probably just been unlucky

What does a 4MEM/62/40000000: 0x82c5e018 error mean?

Hi,

I did the AHT and got the following error:

Its memory failed. Replace it. Memory is not prohibitively expensive.
"Memory sold by the Apple Online Store is guaranteed to be compatible with your Macintosh."
http://store.apple.com/us/mac/mac-accessories/memory
Other than Apple there are only two vendors with which I have personal experience and can recommend: Crucial and OWC. People have reported problems with many other brands, yet Crucial and OWC's prices are as good as any you are likely to find.
Go to Crucial and download the little app that examines your system and recommends RAM upgrade options.
Their prices are good but don't have to buy memory from them - determine what you need and buy it from Crucial or OWC / MacSales.

Error:4MEM/62/40000000: 0x83128718

Hii all,
I did Hardware test for my Macbook pro and I receive this error:
Alert! Apple Hardware Test has detected an error
4MEM/62/40000000: 0x83128718
What the problem in this cause

Apple doesn't release the specific error codes for their hardware tests. This would indicate faulty RAM, however. One of your RAM modules has failed and needs to be replaced.

Kernel Panic 4MEM/1/40000000: 0x7bb1a790

Hello,
My computer is an Intel Imac that is about 6 months old.
Over the last several weeks my Intel Imac has been experiencing problems. It started with a few programs closing unexpectingly every other day. It climaxed the other day with programs crashes right after opening and finally kernel panics (the black screen that comes over the screen with all the different languages saying to restart the computer).
I ran the Hardware Test and got the error message:
4MEM/1/40000000: 0x7bb1a790
I can't even start my computer without it going to the black screen after 30 seconds.
After researching this it seems I have some sort of hardware problem that is pretty serious. I was wondering if anybody knows the specifics of this particular error message I recieved. Can factory RAM just malfuction out of nowhere?
Any help would be greatly appreciated. Thanks for your time,
Pug
Imac Mac OS X (10.4.8)

It's a bad RAM error. You need to take the computer to an Apple service center to either repair the computer or replace defective RAM.
Any RAM can malfunction out of nowhere. However, the error may not be due to defective RAM. It could also be due to other hardware failure on the logic board such as the memory controller.

RAM trouble (4MEM/9/40000000: 0xb865f398)

I have an iMac 21.5" (mid 2010). Off and on over the past year I have had random shut downs "because of an unexpected error". Recently it has gotten much worse. Firefox has crashed a lot, or any other app that is more intensive. I reformatted my iMac, but that didn't help. I ran the Apple Hardware Test, and it gave the error code:
4MEM/9/40000000: 0xb865f398
From what I know, this is related to the RAM. I have four 4GB Kingston Tech modules installed. I removed all but one, then ran the Hardware Test again. After going through all four modules, all the tests stated "No Trouble Found". Then I ran I module in each port to check if a port was bad, and still found no trouble. I've run two at a time and three at a time, but still "No Trouble Found". The only time I get the error message is when all four modules are installed.
Does anyone know what the problem could be? Even if I leave only three modules installed (which didn't give an error message when I ran the Hardware Test) I still have frequent crashes and freezes. I've got OS X Yosemite 10.10.3 installed.
Thanks for the help!

Install the original RAM that shipped with the Mac and then test. If it is OK (I suspect it is) replace the Kingston RAM (which tends to be problematic in iMacs) with a higher quality RAM from either Crucial or OWC, purchase directly from either vendor. iMacs are sensitive to RAM and demand high quality RAM rather than value RAM.
Your issue is one of the following:
Failed RAM
Incorrect RAM
Unseated RAM
