Upgrading to 32 GB ram for late 2103 iMac 27"

Friends,
The computer I'm using is
I wish to upgrade this with 32GB (8GB84) Corsair Vengeance DDR3 8 GB (1 x 8 GB) Laptop RAM (CMSX8GX3M1A1600C10). Is there any problem using this memory? Also I've read in some threads that upgrading to 32 GB ram crashes the system? Is it possible to add 2*8GB and use the existing 2*4GB so that I'll be able to use 24 GB of ram?
Thanks in Advance!

I think that you would get more responces over on the Apple Desktop > IMac discussion thread: https://discussions.apple.com/community/desktop_computers/imac_intel
instead of here at the Final Cut Pro X thread which only deal with editing. That said, I'm not sure that I would proceed with adjusting your Ram modules until you e-mail or speak with an Apple Qualified Technician.
I trust the people over at OWC - Macsales >>http://eshop.macsales.com/shop/apple/memory/iMac
They are very knowledgeable about all things concerning Mac Hardware. They will know how to advise you.
Good Luck!

TA23843 How much memory upgrade can I get on a late 2006 imac

Looking to purchase GB memory for late 2006 iMac. What do I get and how much will it support? I want to install OS Lion but need 2GB to do that apparently.

Here are the specs and maximum capacity for your Late 2006 iMac:
667MHz DDR2 SDRAM (PC2-5300), supports up to 3GB
I would recommend OWC or Crucial as excellent online vendors in the US.
Hope this helps

Upgrading graphics card and ram on late 2011 macbook pro?

Hi. I have a late 2011 macbook pro, and I wanted to know if i could upgrade my graphics card and ram for better performance while gaming. I play WoW and diablo 3 and often notice lag and can only run on low settings. So my graphics are Intel HD 3000 which is integrated, and i was wondering if i could upgrade to a graphics card like AMD or nvidia. Also, would upgrading from 4 gb of ram to 8gb of ram help my performance? Thanks.

You cannot upgrade the graphics card on your MBP. It is soldered to the logic board.
RAM can be increased to 8 or 16 GB. The correct specifications are; 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM.
The best vendors for Mac compatible RAM are OWC and Crucial.
Ciao.

RAM for Late 2006 Macbook Pro C2D?

Can anyone tell me what kind of RAM i would need to order for my machine? Macbook Pro, C2D, 2.16 ghz, 15.4"
I've been having bad luck with crucial.com in getting either bad or incorrect batches of RAM to the point where two batches that came in wouldn't even allow the computer to turn on, and the one RAM that did allow the computer to turn on freezes the machine constantly. It's extremely frustrating.
Orginally my machine had 1 GB of RAM, I have attempted to upgrade to 2GB x 2, so 4 GB's of RAM total.
I was on newegg shopping for RAM, as suggested by a apple genius bar employee, but I'm not sure which RAM to get. Are there any differences in these? Please see attached image.

Welcome Mark!
The 2.16G C2D can access only a maximum of about 3.2G RAM, but installing 2 two 2G modules usually works. For easily a decade, I have purchased all my Mac RAM from two Mac-savvy online vendors and have always received the proper RAM. Here are their links to RAM for your computer:
Other World Computing:
http://eshop.macsales.com/shop/memory/MacBook/Pro/Core2/
Data Memory Systems:
Apple MacBook Pro 2.16GHz Intel Core 2 Duo 15.4" Screen(200 Pin PC2-5300 DDR2 SODIMMs)
We're a little handicapped here by not knowing your location. The links I posted are for US-baaed vendors. The first one ships internationally; the second only to certain countries.
Please consider editing your profile to include your approximate geographic location. That will make it easier for the community to help you.

Memory corruption due to bad RAM in late 2012 iMac

I just unpacked a brand new late-2012 iMac a few days ago. Its specs are basically maxed out, only choice being the 3TB fusion drive. To summarize:
3.4 GHz Core i7
32GB RAM
3TB Fusion Drive
2GB NVidia
Latest patches for Mountain Lion
Since I got it, I have been experiencing intermittent abnormalities with it. Programs randomly crash with error messages along the lines of "such and such file appears corrupt, please run --repair".
I do a lot of programming in my job and just today I started getting bizarre 'segmentation fault' messages in Terminal. What worked just a few minutes ago started crashing with a segfault. The exact same programs have no negative effect on my Macbook Pro and work just fine. In a matter of minutes, the entire iMac became unresponsive and I got the "we shut down your computer to prevent damage" panic screen.
After a reboot, I started thinking it could be some sort of memory corruption. I downloaded the 'memtest' utility and started the basic test with:
memtest all 2
In just a few minutes, below are the results I receive (I re-ran multiple times to the same effect).
Any opinions on whether this is indeed bad RAM? How do I handle this with Apple support? Any suggestions/comments are most welcome.
Thank you,
Ozgun

This must be my last last thing. AHT was on an iMac I bought in 2009. It was included on my "disk 2" along with several other applications. When I wiped and installed the full Lion, AHT was gone. Same is true for the full Mountain Lion installation media. It does not have AHT. I'm not at all sure how to get it back from Apple.
I was able to find it on my SL disc 2 and extract it again from that. Disc 2 won't install on Mountain Lion (the packages are too out of date) but the AHT pkg does.
Since you have it, consider packing it up and keeping it safe. Maybe someone who knows AHT better than I can elaborate on AHT. From what I've seen, you get it when your mac ships but if you ever wipe and reinstall the OS, you lose it.

Which crucial RAM for a new iMac 27" 3.6 Intel Core i5? 1st time buyer

Hi,
I'm thinking about buying the new iMac 27" 3.6 Intel Core i5 and was thinking about getting it with the standard 4 GB of RAM from the apple store, and then adding another 12 GB for a total of 16 GB of RAM. This is the RAM from crucial:
http://www.crucial.com/store/listparts.aspx?model=iMac%203.6GHz%20Intel%20Core%2 0i5%20%2827-inch%20-%20DDR3%29%20Mid%202010&pl=Apple&cat=RAM
I have never bought RAM separately before. What happens to the 4 GB that are already in the iMAC? Do you just buy 12 GB and add it to the existing 4 GB, or do you buy 2 packages of 8 GB and install those two after removing the existing 4 GB? Could someone please advise me which RAM packages I need to buy to max out my RAM? Thank you for your assistance!!
Tim

Do you think it would be worthwhile to sell the 4 GB of RAM that comes with the iMac to decrease the cost buying the 3rd party RAM?
That depends on what you plan to upgrade to, if you are going take it all the way to 16GB I'd probably hold onto the old RAM for few weeks just to ensure everything is safe and sound but don't expect to get much for it. If you buy the RAM from OWC they will give you a trade in value for it and that's something to investigate.
Will adding this new RAM void apple care warrantees?
Of course not, you can download a copy of the manual from the Support site and also get a copy of the warranty. In the manual it will have detailed instructions on how to upgrade RAM, Apple wouldn't put that in there if upgrading RAM would impair the warranty. In the warranty it clearly says if any damage is done that would void the warranty. About the only way you do damage is to pour coffee on the RAM slots while you're upgrading or hammering them in with a ball peen.

[Guide] Install and run Windows 7/8 from an external drive without using bootcamp (works for late 2012 iMacs with 3TB drive)

This is a copy of a post from my blog, you can also Read it on my blog...
Introduction
After I received my new iMac with a 3 TB Fusion Drive, I was disappointed when I realized that Bootcamp was not running on this model and prevented me from installing Windows on it. I wanted to take advantage of the powerful iMac hardware to play games but I couldn't.
There are a few ways of working around this limitation, but I found most of them quite complex and most of the time they required formatting the internal hard drive or repartitioning it and go for a brand new installation of Mac OS X. I was not comfortable with that.
But there is another way, and that is to install Windows on an external hard drive, using either USB or Thunderbolt. Personally I used a Lacie Rugged 1 TB drive that has both USB3 and Thunderbolt connectors. Both work very well.
This guide may interest you if:
You have an internal hard drive of more than 2TB and you can't run bootcamp at all (like late 2012 iMacs with a 3TB drive)
You have limited space or you don't want to dedicate disk space on your internal hard disk drive to a Windows installation
What this guide will make you do:
It will make you erase all your data from your external USB3/Thunderbolt hard drive
It will make you install Windows on your external USB3/Thunderbolt hard drive
It will make you install bootcamp drivers
What this will not make you do:
It will not make you modify anything on your internal Mac hard drive
It will not make you use or install the bootcamp assistant
It will not activate the Preference Pane for the default boot drive. You have to boot by pressing the ALT key to manually select your boot drive each tome you want to boot Windows.
What you'll need
An external hard drive with a USB3 and/or Thunderbolt connector. This drive will be formatted so ensure you saved your files before going further. You can use either an SSD drive or a classic hard drive.
A Windows 7 or 8 install DVD or ISO (check whether to install 32 or 64 bits versions based on your Bootcamp drivers) and the corresponding Windows serial number.
One of the following:
Mac OS X with a Windows 7 or 8 Virtual Machine (use VMWare Fusion or Parallels Desktop for example. Note: VMWare Fusion seems to have some issues with Thunderbolt and USB3. Plug your drive to a USB2 enclosure or hub to work around this -it worked for me-, or use another VM software) → Read the important note below
A PC running Windows 7 or 8 → Read the important note below
Windows AIK (free) running on your Virtual Machine or on your PC, or just the imagex.exe file (the rest of the Windows AIK package is not needed)
Download imagex.exe
Download Windows AIK (this download and installation is not required if you have already downloaded imagex.exe)
Bootcamp drivers for your Mac. You can get these either by running bootcamp from your Mac (Applications > Utilities > Bootcamp) or, if like me you have a 3TB drive and can't run bootcamp at all, use the direct download links here.
A USB stick to store your bootcamp drivers
IMPORTANT: If your Mac has a 64 bits processor, your Windows Virtual Machine on OSX, your Windows installation on your PC and your Windows DVD/ISO must also be in 64 bits!
Step by Step guide
Step 1: Get the install.wim file
If you have a Windows ISO file:
Mount the ISO
If you're on OS X: double click on the ISO file
If you're on on Windows 7: Use a software like Virtual Clone Drive (free)
If you're on Windows 8: double click on the ISO file
Open the mounted drive, then go to the "sources" folder and locate the "install.wim" file. Save this file to C:\wim\ on your Windows installation or virtual machine.
If you have a Windows DVD: open the "sources" folder on the DVD and locate the "install.wim" file. Save this file to C:\wim\ on your Windows installation or virtual machine.
IMPORTANT: If instead of a "install.wim" file, you have "install.esd", you can not continue this step by step guide. And an ESD file can not be converted into a WIM file. So you must get a version of the Windows installation DVD/ISO that has an install.wim file.
Step 2: Clean, partition and format your external hard drive
On your Windows installation or virtual machine, plug in your external hard drive (can be plugged using USB2, USB3 or Thunderbolt at this stage)
Open the command prompt in administrator mode (cmd.exe). To run it in administrator mode, right click on cmd.exe > Run as admin.
Type the following and hit enter to open the disk partitioner utility:
diskpartType the following and hit enter to list your drives:
list disk
This will display a list of disks mounted on your computer or virtual machine. Make sure your drive is listed here before you continue.Identify the disk ID of your external hard drive. Replace # by your real external disk ID in the command below:
select disk #Clean all partitions by typing the following (warning: this will erase all data from your external drive!):
clean
Create the boot parition by typing the following followed by the enter key:
create partition primary size=350
This will create a 350MB partition on your external driveFormat the partition in FAT32 by typing the following:
format fs=fat32 quick
Set this partition to active by typing:
active
Assign a letter to mount this partition. We will use letter B in our example. If B is already used on your PC, replace B by any other available letter:
assign letter=b
Windows will detect a new drive and probably display a pop-up. Ignore that.Create the Windows installation partition using all the remaining space available on the external drive by typing the following:
create partition primary
Format the new partition in NTFS:
format fs=ntfs quick
Assign a letter to mount this partition. We will use letter O in our example. If O is already used on your PC, replace O by any other available letter:
assign letter=o
Windows will detect a new drive and probably display a pop-up. Ignore that.Exit the disk partitioner utility by typing:
exit
Step 3: Deploy the Windows installation image
Still using the command prompt in admin mode (you didn't close it, did you? ), locate the imagex.exe file mentioned in the "What you'll need" section and access its folder. In our example, we have put this file in C:\imagex\imagex.exe
Type the following and hit enter (remember to replace o: with the letter you have chosen in the previous step):
imagex.exe /apply C:\wim\install.wim 1 o:
This will take some time. The Windows installation image is being deployed to your external driveOnce done, type the following to create the boot section (remember to replace o: and b: with the letters you've chosen in the previous step):
o:\windows\system32\bcdboot o:\windows /f ALL /s b:
If you get an error message saying that you can't run this program on your PC, then most probably you are running on a 32 bits installation of windows and you're trying to deploy a 64 bits install. This means you did not read the important notes in the beginning of this guide
If you get an error message on the options that can be used with the BCDBOOT command, then it's because you're installing Windows 7, and the /f option is not supported. If that is the case, remove /f ALL from the command and retry.
Step 4: Boot from your external drive and install Windows
Plug in your external drive:
If you've done all the previous steps from a Windows PC, unplug your external drive from your PC and plug it to your Mac, either on a USB3 or a Thunderbolt port.
If you've done all the previous steps from your Mac using a Virtual Machine, ensure the external drive is plugged in to a USB3 or Thunderbolt port. Using USB2 should also work but you'll get very poor performance so I don't recommend doing that.
Reboot your Mac and once the bootup sound is over, immediately press the ALT (option) key and release it only when the boot drives selection screen appears. If you did not get the boot drives selection screen, reboot and try again. The timing to press the ALT (option) key is quite short. It must not be too early or too late.
On the boot selection screen, choose "Windows" using the arrow keys on your keyboard, then press enter.
The Windows installation starts. Follow the on-screen instructions as normal. The installation program will restart your computer one or 2 times. Don't forget to press ALT (option) right after the bootup sound, and boot on Windows again each time to continue the installation.
Step 5: Install bootcamp drivers
Once the Windows installation is complete, plug in the USB stick where you stored the bootcamp drivers (see "what you'll need" section), open it and right click on "setup.exe" and select "Run as admin". Follow the on-screen instructions.If you have an error saying that you can't run this program on this PC, obviously you have installed a 32 bits version of Windows and the bootcamp drivers for your Mac are made for a 64 bits version. You have to restart the whole guide and make sure to get a 64 bits version of Windows this time!
Once the bootcamp drivers are all installed, reboot and press ALT (option) after the bootup sound to boot on Windows again. And Voilà, you have Windows installed on your USB3/Thunderbolt drive running on your Mac.
Now each time you want to boot on Windows, press and hold the ALT (option) key after the startup sound and select "Windows", then press Enter.

Hi i'm trying to follow your guide, I installed windows 8 on bootcamp to do it planning to remove it after the operation is done, but i get stuck at part 3: every command i give to imagex i get a pop-up ftom windws asking how do I want to open this kind of file install.wim and imagex does nothing, what do i have to do to stop those pop-ups?

8GB of ram for late 2008 Macbook

Offically it can't be done. In the realworld I've hear it can.
How, from where and at what cost? I'm in the UK and I've already trield Crucial UK.
Any ideas?
Thank you very much.

Spoke to Crucial UK last week. This is what they had to say about exeeding Apple's rmaximum reccomended ram upgeades. Note - this relates to a late 2008 aliminum Macbook.
"I really do not recommend exceeding 4GB...we test the machines in our labs for the maximum capacity it can take, and in numerous cases APPLE recommends a certain capacity and we find that the machine can take more, so we type our figure, as of this I strongly recommend that you stick to the 4GB recommended by us as we’ve tested the machine and that’s as much as it can take.
If you want to take your chances with 8GB kit ( 2 x 4GB ) modules, then you will find it on this link'
What do you think?
What are the risks of going over?
Thank you.

Memory upgrade costs/ types of RAM for MacBook

I want to upgrade a new macbook to 4gb (not the Macbook on my profile which is older). The cost of official Mac memory is about 500 pounds UK. The cost of 3rd party (crucial) is about 100 pounds UK. I know Apple charge extra but the difference seems extreme.
Looking closely at the specs there are some differences, e.g. apple is fully buffered, ECC - but the crucial are unbuffered, non ECC.
Is this a meaningful functional difference, that explains the cost difference? will the cheaper Crucial ones work as well as the apple ones?

I wouldn't think so. I didn't notice any any additional ICs on my factory installed Hynix modules on my Santa Rosa MacBook. All I saw were the memory ICs and an SPD EEPROM. I can check the part number when I get home, but I'm sure it's non-ECC and unbuffered.
Got it.
Factory installed memory in my Santa Rosa MacBook were two Hynix HYMP564S64CP6-Y5 SODIMMs. Here's the spec sheet from Hynix (may need to cut and paste to a new window/tab):

Maximum RAM for Mid-2010 iMac 3.2GHz w/ Core i3 Processor?

I am looking to upgrade the RAM on my iMac. This is the first time I've ever done so and the reason for it is that I'm finally starting to experience some noticeable lag while playing games. I'm not a hardcore gamer by any means but I feel as though the kinds of games I play shouldn't be struggling so much to run. Some examples of games I've played that have had trouble include Amnesia: The Dark Descent and Left 4 Dead. These games came out a few years ago so it's not like I'm pushing the limits of my machine here! I've done quite a bit of research online but I've come across some conflicting reports on the maximum amount of RAM I can install.
Apple's support files state that the computer can hold up to 16GB of RAM, but then go on to state that this would be equivalent to a 4GB SO-DIMM in each slot. Is that because there are four total slots in my iMac? (See... I told you I'm new at this!)
At the same time, I've also read that it is possible to install up to 32GB of RAM in this particular model of iMac. Is this actually true?
Whichever the case may be... can anyone recommend some good, quality, dependable brands of RAM? Because in doing my research I've read a few horror stories about faulty RAM (and no... I'm not planning on shopping on eBay so don't worry!).
My final question is this: Is upping my RAM actually worth it? As in, will it help my games run smoother and/or better? I ask because I've also wondered if the video card might be the bigger problem (which I hope it's not because I have no idea if it's even possible to replace that).
Sorry for being so long-winded but I just really want to make sure I do this right and don't waste my money. Thank you in advance for any help! =)

Your computer has 4 slots. When Apple shipped the computer the largest DIMM shipping was 4GB so Apple advertises 16GB as the max. According to OWC that remains the maximum for your computer, only the i5 and i7 models can be upgrade to 32GB. At this time 16GB should be plenty for most people.
There are a number of things that have an impact on speed and, of course, one of them is RAM. When your computer first came out the operating system you were using was less RAM hungry. It seems that each new upgrade (or every other OS upgrade) ups the RAM ante. Other things that have an impact are the utilities and programs you run behind the scenes. They can burn up lots of CPU cycles and RAM. Hard drive space is another factor - the operating system and programs need room for temporary files and when this room isn't available the computer slows down. So, are you running anything like anti-malware? Dump it, not needed. Do you have about 25GB of free drive space? If not, free some up.
Quality RAM - not only what you buy but who you buy it from is important. I go with Crucial or OWC.

HT5628 No support of Windows 8 for late 2009 iMac?

I have an iMac late 2009, 2,8 GHz and i wonder why Windows 8 is not supported by Apple. After only 3 years no support by Apple.
A Mac Pro from 2009 get support, why?
Thank you Apple, this was my last computer bought from you.

Read projectRelentless thread here:
https://discussions.apple.com/thread/4897066
on how to install Windows 8 on non supported Macs.
BTW the Tackpad ++ drivers referenced Csound1 DO NOT work on the Magic Trackpad as Vladimir is concentracting on the MacBook Macbook Pro trackpads only for now.
There are some workarounds for the Madic Trackpad but they pale in comparison to Trackpad++

Ergonomic Brightness Level for Late 2009 iMac 27" i7

Hi. Apple seems to default the brightness level to full when you buy it and I've read some iMacs flicker unless it's brightness level is set to full bright. For the late iMac 2009 27" i7, what's do experts say about ergonomic brightness level for this Mac, for LED LCDs? I won't be doing professional printing by the way. Thank you in advance.

I set mine to something between 50-70% of the max depending on the time of day and the amount of sunshine.
No buzzing at all.

RAM for current gen iMac-- Urgent

I have the current gen 24" 2.8Ghz iMac with 2GB ram.
I want to upgrade it to 4GB. I noticed in the system profiler it says bus speed is 1.07 Ghz. Does this mean I can take 1077Mhz SODIMM 200 Pin ram? The memory section says I have 2GB of 800 Mhz...
Kinda want to order it ASAP
Regards

You need to order 800MHz RAM. The 1066MHz in the new iMacs is the chipset bus speed, but RAM does not run at that speed.
I just put 4GB of 800MHz RAM in my 3.06 iMac.
