Macbook Pro 2012 overheats with 16GB RAM. Is this normal?

Hi guys,
I installed 16GB RAM on MBP 2012 13" running I5 for peace of mind, as I think I might need all of it when using say autocad and other 3d visualization programs in bootcamp. Also I am an architect/designer who likes having a tone of stuff open at the same time between browser and emails and music and work. That's just the way I am.
But there is one thing I truly dislike and that's a hot laptop on your lap when in bed, say. It also just makes the whole karma horrible I reckon.
Anyway, after trying 8GB thanks to a mix up at the store where they gave me two 4GB sticks instead of the 28GB I had ordered I noticed the same improvements for basic use I have now with the full 16GB package. But now I feel that the laptop is overheating using Mavericks which wasn't happenng before. The system shows the full 16GB in operation so I don't think there is a malfunction there. But I want to ask of this behaviour is considered normal or i on the other hand I should be going to the shop where I got this from to complain?
This is the RAM I bought:

**** it's hot!!
Thanks,

The amount of RAM will not be responsible for heat, the application(s) and the amount of resources it(they) require(s) from the CPU/GPU will create the heat. This is the 'official' Apple policy on how a MBP should be used:
http://www.apple.com/support/macbook/care/
Note this particular paragraph:
If you install istat menus:
http://bjango.com/mac/istatmenus/
and open Activity Monitor to ALL PROCESSES and CPU to display values from high to low and post images of both when the MBP gets hot, we may be able to determine if it is normal or not.
Ciao.

Can I buy a Macbook pro retina 13" with 16gb RAM and i7 processor in an physical Apple Store in Spain?

I´m looking a Macbook pro 13 inch, but I would buy it with an i7 processor and 16Gb ram. Can I buy it in a spanish physical Apple Store or only in the Apple Store online?
Thanks

At least in Spain, some Apple Retail Stores have got specific build-to-order MacBooks Pro available, but they are just because they are sold better than any other build-to-order MacBook Pro.
However, as Kappy said, it's quite difficult you can get one with the configuration you want. Have a look at the list of Apple Retail Stores in Spain, choose one and call them to see if there's one available > http://www.apple.com/es/retail/storelist The best way to buy a build-to-order Mac is through Apple Online Store

Macbook Pro 2012 overheats with Diablo 3

I just bought the new 2.6GHz 8GB RAM Macbook pro (non-retina) last week, and the machine overheats horribly when I try to play diablo 3 (even on the lowest settings). It runs fine for a couple minutes, then the aluminum becomes so hot that I cannot even hold my hand on it for 30 seconds. Also, the game begins to lag terribly. This overheating problem occurs during some regular internet use also and slows it down to the point where it's impossible to watch YouTube. I know it isn't my wifi connection since I run the same things on my iMac in the same room (not at the same time). Am I doing something wrong? Thanks in advance!

My new 15" MBP (Same specs are yours) runs Diable 3 fine. Everything is turned up and it's very fluid. I rest my MBP on a cooling pad to help with the cooling. Mine does get hot, but I have played it for several hours with no lagging/stuttering (Caused by excessive heat).
Your MBP will run Diablo just fine (And WoW for that matter. I have everything set to Ultra and I push ~35FPS in SW.)
Instead of troubleshooting it, I would make an appointment with the Genius Bar, or if you don't have an Apple store close by, give them a call. There is something wrong with your MBP.
Hope you get your MBP fixed quickly

Brand new Macbook Pro (early 2015) with upgraded ram lagging in the simplest tasks

I received a brand new 13 inch macbook pro (early 2015) with upgraded ram (16 gb) about two weeks ago. I was expecting it to do tasks faster than its predecessors (the macbook pro which came directly before it, which my father owns, and the early 2009 which is now a family computer), but became dissapointed when it began crashing basically as soon as i started using final cut pro, and ever since it has been lagging everywhere else! I have check my activity monitor regulary due to this issue and have noticed "kernel_task" taking a large percentage of CPU (when im not using the computer all that much around 10%) and it uses 1.5gb of ram upwards constantly without fail! I am aware that this is the operating system so i dont really want to fiddle around with it but it does sound a little bit high to me. Originally it was slightly tougher work on final cut that would crash it, hence why i haven't seriously questioned it until now, but currently i cannot even move my curser around without getting the spinning beach ball of death! Please help me!

Macbook Pro 13" Late 2011 16gb RAM error

Hi,
I've got a 13" Macbook Pro Late 2011, Intel i5 2.4ghz, 16gb RAM Corsair (mac branded), 500gb 7200rpm Seagate Momentus.
Recently my mac keeps restarting 3-4 times a day. I've done the Apple Hardware Test and I found out a problem with my memory (4MEM/9/40000000).
So I've tested each stick and the funny thing is that they both works well (without reporting errors) alone. When i put the second stick (no matter if the first or the second one), AHT shows up the error.
So, each stick alone -> OK
Two of them together -> BAD
I've tested also the two sticks that originally came with my mac (2x2gb) and everything went fine.
What do you think people?
Thanks!

Me too!

2 Ram upgrade + 120 16GB SSD and a regular reboot.
I checked with the RAM it works fine.

MacBook Pro 13" Late 2011, 16GB RAM and Apple Premium Service Center

Hello all,
My dad has a MacBook Pro 13" Late 2011, it came with a 4GB RAM. When he got Parallels and installed Windows 8, 4GB RAM were not enough to even deal with Safari so he had to buy 16GB RAM from Cruical. Today when he went to Apple Premium Service Center here in Qatar (51 East) they refused to install the x2 8GB RAM and only installed one of them. They kept warning my dad that installing the whole 16GB can cause issues with the MacBook Pro HDD and can make it go faulty. I wanted to ask if installing RAMs can pose the HDD life to any danger. Because my dad uses his Mac for work and wouldn't like to lose any of his files against small additional speed.
Thanks.

its very easy to do, here are step by step instructions with photos

New macbook pro 2012 preinstalled with lion can't be reinstalled?

Hi everyone,
I'm new to mac os x and I just bought a new macbook pro 13" four days ago which came preinstalled with mac os x lion. I tried to do a clean install on the third day to experience doing it myself for the first time. here's what I did:
1st try
@DU I perform erase Macintosh HD, set the partition table to GUID, partitioned the drive,
exit DU and then selected reinstall mac os x from the mac os x utilities,
I just clicked continue, continue, then it did some eligibility checking and verification.
after a while the dialog window showed this message " This version of Mac OS X 10.7 cannot be installed on this computer."
there's no other option below than quit.
2nd try
restarted macbook then pressed down option+command+r
the globe logo came out. I connected to my home wifi and a progress bar indicator came out. after the progress bar completed, the Mac os x utilities came out.
I selected reinstall mac os x from the mac ox x util. I clicked on continue, continue.. an eligibility and verification followed and after a while I got the same message saying "This version of Mac OS X 10.7 cannot be installed on this computer."
3rd try
I restarted macbook again and pressed down option+command+r
I did the steps from the 1st try again but I still get the same message "This version of Mac OS X 10.7 cannot be installed on this computer."
Can anyone help me out on how to reinstall Lion? or did I missed out anything? or should I send this macbook for repair? or just return it?
appreciate any advice...thanks.

I remember something similar happening when OS X Lion was first released. At that time, the mid-2011 MacBook Air hit the store shelves and many users could not do a full reinstall from the Apple Servers. The reason, was that the MacBook Air had a specialized version of OS X Lion with a build number that has 4 numbers (i.e. build 11AXXXX) following the OS release number. In contrast, the release version of OS X at the time was 11A511 which uses 2 or 3 numbers and is a universal version of OS X that can be used by any Mac. The reason why you are experiencing problems installing OS X Lion is because you got the newest MacBook Pro which has a specialized build of OS X Lion and as in previous cases, it has 4 numbers meaning that it is a specialized version of OS X.
You appear to be running the following version of OS X Lion:
As you can see, it's an exclusive and optimized version of OS X for your MacBook. Your only hope is that Apple releases the OS X 10.7.5 release which most likely be universal with all Macs.
I suggest going to the Genius Bar to sort things out.
Hope my little explanation helps.

Macbook Pro (late 2008) with 8GB ram sporadic freezing / hanging

Hi,
Last year, I was running Lion on my late 2008 MBP with 4GB ram with no problems. Whilst 4GB is the maximum officially supported for my machine, forum posts suggested that some people had no issues running it with 8GB.
I went for the upgrade and everything was fine, with no hanging - 8GB on Lion on my machine seemed to work fine.
When I then upgraded to 10.7.2 I had a separate issue (to do with an old install of PGP) which meant I had to do a fresh install of Lion from scratch and then restore from Time Machine to get it back working. Ever since I did this, I have experienced odd behaviour, notably:-
Machine has a tendency to hang / freeze every now and then for up to 10 secs and sometimes with the spinning wheel and sometimes also requiring a hard reset
Any mounted drives in Finder (dropbox, Truecrypt) sometimes don't come up at all, with the Finder progress wheel spinning in the bottom status bar of the window, and only a "Relaunch Finder" resolves this and allows me to access the mounted drive.
Machine seems a little sluggish despite me keeping on top of maintenance activities for my machine (as I used to for SL and Lion when I first installed)
I was wondering whether there was something whereby Lion would work fine had it been installed whilst the machine had the officially supported 4GB (and then later upgraded to 8GB) as opposed to installed on a machine with 8GB (which only officially supported 4GB) at the time of install. As above, everything was working happily with the 8GB until I had to do a completel refresh from scratch.
Has anyone else had experiences of anything similar and can shed some light? I am considering refreshing and restoring from time machine again with just 4GB in the machine and then putting the extra 4GB back in after the restore, but don't want to do this unless there is any evidence to suggest this will address some/all of the issues I'm experiencing.
Thanks in advance.

Thank you, basilmir. Below are the specs from my Macbook prior to the Snow Leopard and RAM upgrade. To upgrade to ML I needed to first upgrade from Leopard to SL. I expect to do that later today. In the same screen as below, I now see the memory as 8GB. When I run Activity Monitor I am seeing 7.75GB so I am guessing that the video card is using the "missing" 256 meg.
Hardware Overview:
Model Name: MacBook
Model Identifier: MacBook5,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB
Memory: 4 GB
Bus Speed: 1.07 GHz

Mu macbook pro 2012 wont start it goes into this i cant get anything help please

my macbook pro is only on safe mode, was working fine then plugged in battery charger and it came up with a funny screen and voice asking what language i wanted i did disc repair but it said it didnt need it all i can get into is the help line PLEASE HELP

Adam,
if preserving your files is worth your effort, then copy them to an external drive; if not, then don’t. Once you’ve preserved whatever you care to, go back into Disk Utility from Recovery mode, select your internal disk from the left-hand side of the window (probably the first item in the list), and select the Erase tab on the right-hand side. In the Format dropdown, select “Mac OS X Extended (Journaled)”; in the Name textbox, enter the name for your reformatted volume (“Macintosh HD” is typical); and then press the Erase… button. Once the erasure is completed, exit Disk Utility, and then select Shut Down from the Apple menu. When you power it up, OS X Internet Recovery will download your MacBook Pro’s original version of OS X from Apple’s servers, and then reïnstall it. When it restarts after the installation, run Software Update to bring it up-to-date, and then copy your preserved files back to your internal disk.

Which MacBook Pro Models can handle 16GB RAM

Hey, I'm looking to get a refurbished MBP and I'm wondering which models (that came with i series processors) can support 16GB of memory. Any help will be appreciated, thank you.

jadasneez,
any non-Retina model from 2011 or 2012 (they all have Core i5 or Core i7 CPUs) can support 16 GB of RAM, as well as any Retina model that came from the factory with 16 GB of RAM soldered on.

I have a macbook pro 5,5 with 4gb ram and would like to upgrade to lion is this possiable please help

i got a new iphone and ipad mini now i can't use my computer plaese help and let me know if i can go to lion or am i up a creek

Snow Leopard is back on the online Apple Store, at least in some countries. In the US:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
If it's not listed on the web site of the Apple Store in your country, call the online Apple Store,; they may still have copies of Snow Leopard available .
If they no longer have it available, you'll need to look to private sellers, and the prices are rising quickly. If you buy from a private seller, make sure you get the retail disk set (white label with a picture of a Snow Leopard), not the system disks from another model of Mac (grey label).
Once you get the disk, install the OS and run Software Update to get to the latest version of 10.6 and iTunes. You should then be able to sync.
Regards.

Can I take RAM from MacBook Pro 2012 and install in MacBook 2010

I am upgrading a MacBook Pro 2012 from 8G to 16GB of RAM
Can I take the old 2x4G RAM DIMMS and install them in my daughters White MacBook 13" 2010 (7,1)
Thanks...

Your 2012 tech specs state 1600 MHz:

whereas the 2010 white Macbook takes 1066 MHz:
So, the answer would be no.
