How much memory can use my early 2011 15 inch MBP ?

I'm looking to buy new memory for my early 2011 15 inch MBP because it's running way to slow ( i have 4GB memory). I want to put 16 GB on it. Will it support it?

I too want to add memory to my 15" MacBook Pro, early 2011.
It has: 2.2 GHz Intel Core i7. Currently I have 8GB installed. I saw this post and thought yahoo! HOWEVER, when I look on Apple's site it says no. That the memory is tapped at 8GB. I really hope to go to 16 GB.
Here is the link I found:
https://support.apple.com/en-us/HT1270
So, since this post says the laptop will support 16 GB and the above says only 8 GB. Please help.
Thanks,
Ginger

I have an iMac 5,1 with an Intel Core 2 Duo. I'd like to be able to use iCloud, but need Lion which is too big. How much memory can I add? And will this upgrade allow me to install Lion?

I have an iMac 5,1 with an Intel Core 2 Duo. I'd like to Lion, in order to use iCloud, but the specs indicate I don't have enough memory. How much memory can I add? And will this upgrade allow me to install Lion?

I believe your model iMac can address 3 GB RAM; the minimum for Lion is 2 GB - however, that is an absolute minimum for very light use. You would be much happier with a minimum of 4 GB.

(You can install 4 GB, but it will only be able to address about 3.1 - 3.2 GB)

How much memory can I install in my mac book pro?

Mac book pro 2.4 GHz late 2011 i7....How much memory can I install? Currently have 4Gb but want to run Win 7 on VMware and want to make sure my user has enough

The position of Apple is that the Late 2011 can take 8 GB, however, OWC, http://www.macsales.com and Crucial, http://www.crucial.com both guarantee their 16 GB ram packages to work. Both are sellers of high quality ram that is guaranteed to work in Macs.

How much memory can i put in my imac

how much memory can i put in my new imac

Assuming it's a 27" 2012 machine, it will accomodate up to 32GB. I'd strongly recommend reputable vendors such as OWC (www.macsales.com) or Crucial.
If you bought a 21.5" iMac the RAM is not upgradeable. The 21.5" machines will accomodate up to 16GB from Apple however you have to order the machine with 16GB directly. OWC does provide RAM upgrade kits for the 2012 210.5" iMacs however it is MAJOR surgergy and is full of risks including fatally damaging the machine and invalidating the warranty.

How much memory can I put in my MacBook?

Hey,
I have a MacBook.
Processor 2.13 GHz Intel Core 2 Duo
Memory 2 GB 800 MHz DDR2 SDRAM
and I am wondering how much memory I can put in the thing.
By day my wife uses it for work and pictures and stuff and by night I use it for DJing so I need AS MUCH space as possible.
Thank you for your time!!

Up to 6gb although 4gb would be cheaper http://eshop.macsales.com/shop/memory/Apple_MacBook/White/2.13GHz

I have an iMac OS X Version 10.5.8 but I also have a MacBookPro 10.7.5 version, why software updates are not the same? For example, when I want to know how much memory can not store in the same way in either computer.

I have an iMac OS X Version 10.5.8 but I also have a MacBookPro 10.7.5 version, why software updates are not the same? For example, the way to see how much memory I have in my iMac is diferent than MacBookPro. And where I can see the memory of the disc I've got in my iMac? Than you very much.

If you want everything the same on both computers you need to be running the same OS X version. You can't because your iMac is a PPC machine, not Intel.
But to see information about your hard drive is the same for both. Simply select the drive icon on the Desktop. Press COMMAND-I to open the Get Info window. Disk information is in the upper panel.

How much memory can Premiere Pro use on a new Mac Pro?

I'm ready to upgrade memory on my Mac Pro Late 2013 6-core. Does PP CC 2014 have a limit on how much RAM it can use? Some apps never use more than a certain amount, so I don't want to buy a lot of memory if PP will never put it to work. (I made that mistake when I was an FCP user.) Is there a limit and if so, what?
Also, are there any Mac Pro users who have an opinion on optimum RAM? I currently have 16GB (4x4GB) with 10GB reserved for PP. I am in the middle of a very large project and have noticed some irregularities and spinning balls. I assume that they are from memory shortage since quitting all other apps and restarting PP seems to fix the issue.

Not a Mac expert here ... but I do know there's folks running 64G ram and so going up from 16 will work fine. Now ... as to which is the "choke-point" ... that's a bit more techie than I can answer off the bat.
The Adobe video apps can put a pretty good strain on all of the computer's hardware, and "balancing" the assets of the hardware to the usage patterns of the software is always the trick. Memory never hurts ... but if the spinning ball is a video-ram problem, changing mobo ram isn't going to do much. The various areas they go into great detail on within the pages of the "Tweakers Page" (found within these forums threads, check the hardware forum) are of course, mobo, chip/s & cores, ram, disc in-outs & arrays/layout of project/footage & program files, video card & ram.
Your problem might be best solved by more RAM; it might be that it's a disc read/write issue and either more internal or eSATA II discs to spread read/write processes over would be best ... or taking an array of discs and using a fast multi-disk RAID array to speed things up even faster, or a video card upgrade.
So ... where you might want to go is the the Hardware Forum and give your computers complete specs, including disc layout and usage, and see what folks there think needs tweaking.

How much memory can I stuff in my Mac Mini?

I have a mid-2011 i5 2.3 Mac Mini that came with 4GB memory (2X2GB). After a while, I upgraded it to 2X4GB chips, and today, I installed 2X8GB chips for a total of 16GB internal memory. How much can I stuff in there? Can I put in 2X16GB chips?
Also, to speed things up, can I install one of those Fusion drives into the Mac Mini?

There has only been fanciful reference to 16 GB SODIMMs. Middle of last year, 8 GB SODIMMs were $750+ each. Now they are $45 through Crucial. 16 GB SODIMMs may be out there somewhere, but likely cost $3000 each -- just my "off the cuff" estimate as I have done no research.

How do I find out how much memory can my macbook take?

I am trying to find out is my macbook can improve somehow performance (i am experiencing some slow downs when i have a number of applications open) by expanding the memory? now i have 2gb+2gb....can i go higher? thank you

8 GBs is the maximum you can install. But adding more RAM may not help:
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.
You might also consider some maintenance:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard. These utilities have limited or no functionality with Snow Leopard and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc. Other utilities are also available such as Onyx, Leopard Cache Cleaner, CockTail, and Xupport, for example.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Backuplist
Carbon Copy Cloner
Data Backup
Deja Vu
iBackup
JaBack
Silver Keeper
MimMac
Retrospect
Super Flexible File Synchronizer
SuperDuper!
Synchronize Pro! X
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup

How much memory can I put in?

Mine is a 24", Early 2008 2.8 GHz Intel Core 2 Duo 4 B 800 MHz DDR2 SDRAM for memory, how much can it handle? w/Yosemite 10.10 & 2 2G right now.

Add a 4GB chip.
The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I now have 6GB installed on a machine supposedly limited to 4 GB.

How much memory can my macbook pro handle?

I have a mid 2012 macbook pro 15" i7 quad core 2.3 ghz with factory 4gb of memory. Just curious how much more memory I can install in my mac? Apple says 8 GB but others say 16 GB. Any thoughts?

Apple has recommended 8gB total because 4gB chips were readily available during the development phase of the MacBook Pro. They do not re-test the capabilities when newer, higher capacity chips become available. Outside companies and RAM suppliers test the units with higher RAM capacities, thus the confusing total RAM capabilities.

How much memory can Audition make use of

I am considering a new computer. If Audition 3.0 will make use of ram in excess of 2 MB I will put it in. However, the "system requirements" gives only the minimum and does not suggest optimum. Many programs will not address ram in excess of 2 MB.
Does any one know?

Yeah, what Runaway said. That's what I believe anyway, based on my own occasionally painful experience running Au3 on P4 1.7 Ghz with 2 GIGs of RAM. Things start to stutter and crap out when I get over twenty tracks running in Multitrack with realtime EQ running on everything and ESPECIALLY compression running on only a few tracks.
My next purchase is going to be a new computer, dual core with tons of speed and real estate.
