How much RAM is my blackbook addressing?

i have a 2.16 blackbook. i recently swapped out the 3gb (1gb+2gb) ram i had for 4gb (2x2gb). i read that my version of the blackbook can only address ~3.3gb with 4gb installed, but so far, i can't find any evidence of that. both activity monitor, terminal's top program, and about this mac seem to suggest that my computer is addressing all 4gb ram. is there something i'm overlooking? is there any other way to figure out how much ram my computer is addressing? thanks.

It does not. Activity Monitor reports:
Wired RAM
Active RAM
Inactive RAM
Free RAM
The total is your installed RAM.

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.

*Noob* Which of these would I use for a scratch disk? How much Ram?

Hello, I am fairly new to Photoshop as I have used Lightroom ever since I've been a photographer. I recently got into Photoshop with the cloud as well as layering multiple exposures together. I never KNEW anything about scratch disk, until yesterday.
First let me stress, please answer my questions in layman's terms. I search the net before I start a topic on a forum and I read a lot of answers that seem to be responding to people who have a general idea of what is already going on. Remember, I DO NOT. Here are my questions:
A:If the scratch disk acts like RAM, do I need to allow it to use any of my ram at all? If so, how much? I have two Macbook Pro's, they are the highest model Apple makes, both have SSD drives, Quad Core i7's, etc. I unchecked my Macbook hard drive and told it to use an external SSD drive that is plugged in via USB 3.0. Would it be better to use an HDD instead of SDD? I have lots of hard drives to choose from due to being a music producer.
B:When I exit the program does it delete all the data it created? This question is two fold, does it delete it regardless if I saved the project or not? If I save the project does it stay there? What if I delete the original photo, was the photo imported into photoshop upon camera raw?
C: Like question A, how much ram do I choose? I have 16GB of Ram in each of my MacBooks.

OK, I have now copied your hillbilly text and pasted it into a text editor to change the typeface so I can read it.
I'll try to address the lose ends here.
A:…I have two Macbook Pro's, they are the highest model Apple makes…
Please forgive me for not being impressed. I just happen to consider any laptop a sub-optimal choice for Photoshop photography work. My personal opinion. (Please don't ask me why.)
, both have SSD drives,… I unchecked my Macbook hard drive and told it to use an external SSD drive that is plugged in via USB 3.0. Would it be better to use an HDD instead of SDD?…
I assume you are talking about using the external drive as your primary scratch disk, not as your boot disk. That is the appropriate thing to do. HD or SSD will both do the job fine, as long as they're physically separate, dedicated Photoshop scratch disks.
Obviously the internal drive will be your boot disk. Adobe applications really like to reside on the boot disk, the drive where the OS resides.
B:When I exit the program does it delete all the data it created?
This question is two fold, does it delete it regardless if I saved the project or not?
If I save the project does it stay there? What if I delete the original photo, was the photo imported into photoshop upon camera raw?
NOTHING is ever imported into Photoshop, ever. You use Photoshop to open your files exactly where you put them in the Apple Finder. And you save them wherever you wish, in the Finder as well. Your images will always reside in the Finder.
You don't import files into Adobe Camera Raw either. You open them in or with ACR.
Of course you need to save your data, not only when you quit the application, but at frequent intervals while you're working on it. Nothing you saved will be deleted by Photoshop. How can you even conceive and ask such a question? ?? !
If you ever try to close a file or the application when you have open, unsaved files, the application will ask you for confirmation in an unmistakable way.
Your images will always reside in the Finder, wherever you put them.
Photoshop does not have the abominable "Libraries" scheme that made me detest Lightroom when I tried it. Nor does Photoshop hide your image files in "packages" like the even more abominable iPhoto does.
Please forget anything you may be accustomed to in Lightroom and/or iPhoto, and approach Photoshop with a fresh mind, respecting it like the granddaddy of image editors it is.
C: Like question A, how much ram do I choose? I have 16GB of Ram in each of my MacBooks.
Again, you don't "choose RAM", instead you select a percentage of dynamically changing Available Memory (not RAM; see above) to allow Photoshop to use. Leave at around 70%.
Please see the following post for an important tip.

How much ram is the the ipad air?

Any one know how much ram is in the new Ipad Air?

I saw an article this morning, sorry but can't provide a link, that compared the specs of an iPad 4 with an iPad Air. They are very similar except for the processor speed and the addition of 64 bit addressing. If the speed and 64 bit are important than an upgrade is a good idea but if you feel your iPad 4 is working well you might wait.

How much RAM can I put into my Macbook Pro?

Here's my info:
Model Name:          MacBook Pro
Model Identifier:          MacBookPro4,1
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:          2 GB
Bus Speed:          800 MHz
I want to upgrade my RAM, as the computer is showing a bit of age at 3 years old now. I looked at this support page:
http://support.apple.com/kb/HT1270#link8
And judged the installation to be easy enough for me to do, but I'm confused as to how much RAM I can buy. The conflict I see is that "Additional notes" says I can use up to 8GB of RAM, but the table says only 4GB. What's throwing me off is basic math -- is that 4GB only referring to my slots (thus 4+4=8) or is it saying that anything over 4GB will not be recognized by my computer?
I spoke with someone at Apple, but he seemed a bit confused by my question, and eventually gave me a "yes" that was timid enough that I felt the need to post here. So, I'd appreciate the support! Thanks a lot, everyone. I'm just looking to not spend more than I need (in terms of buying excess RAM), and make sure I don't ruin my Mac in the process.

The MacBook Pro 4,1 can acces a maximum RAM of 6GB
However RAM comes in 4GB modules and you have two slots, so you install 8GB (two 4GB modules) and can only access 6GB of it according to MacTracker.
Use the free Crucial.com site to make sure your getting the extact specified RAM specs, you can buy it anywhere if you like.

How much ram can my iMac take?

Hi all, just bought a iMac a few days ago and I'm just wondering how much ram can it take as I want to upgrade it. It didnt come with a manual, so I don't know.
Here's the spec so far
Early 2008 20"
Processor 2.4 GHz Intel Core 2 Duo
Memory 2 GB 667 MHz DDR2 SDRAM
Graphics ATI Radeon HD 2400 XT 128 MB
Software OS X 10.8.2 (12C60)
Thanks for any help in advance

There are two answers: the official Apple answer and the "you're on your own" answer.
1 - For the official iMac max RAM, see iMac Memory specifications and upgrades
2 - For the "your're on your own" answer, everymac.com has a list of the Actual Maximum RAM you can put in every model Mac. In many cases this is more than the official maximum RAM.
After deciding how much RAM you want to put in your iMac, I suggest going to Crucial.com and use the memory advisor or system scanner to see what RAM modules are compatible with your iMac.

How much ram does my macbook pro have?

How can I tell how much ram memory my mac book pro originally came with? I now only have 2 gbs left and am running out of space with all my photos, aps, videos and music. I don't want to keep moving things on and off the computer with an external hard drive. Is there a way to get more ram? My ipad has 64gbs and holds everything - but apparently my computer doesn't.

Time Machine backup disks should be external ... separate from the computer.
Several places sell external disks that are already formatted for Mac. Others tell you that external disks not formatted for Mac can be reforatted, but save yourself the grief for now and buy Mac-ready.
Buy a *new* disk, in my opinion. Do not reuse an old disk.
Some can suggest certain brand names as "better", but even the best disk-brand will have bad apples in the mix.
If any others have a convenient link for Time Machine Tutorial, please provide. I have learned enough alreay, generally through trial and error on my own.
But focus on getting that first backup done within the next 2 days.
As to "probably need a new HD", perhaps you can move enough off to an external disk. Cross that bridge after you get the backup.
If you get the sense that critical things are done first and that you should save yourself complex things like "how to replace a harddisk" for later, you are reading my posts correctly.

How much Ram can my Macbook use? What Hard drive should I upgrade to?

Hi Everyone.
I have a 2008 ish macBook with 4gb of Ram. I use vmware Fusion to run Windows every day and I also use Aperture on a regular basis.
I'm looking to breath some life into this old machine and want to know how much ram the motherboard will support. Here are the machine's specs.

Bus Speed:          800 MHz
Boot ROM Version:          MB41.00C1.B00
How muck Ram will the machine support?
My Hard drive is also nearly full and I would like to upgrade to a 500gb drive. Any suggestions on which drive to choose?
Thanks!!

You can install up to 6 GBs of RAM. There are any number of good choices for a hard drive replacement. I suggest visiting OWC for information on pricing, makes, and models. They also provide video tutorials on how to replace a drive in MacBooks.
To prepare for the upcoming release of Lion I also suggest spending $29 to buy a Snow Leopard DVD and upgrade your OS.

How much Ram can my MacBook hold?

Hi, I'm looking at upgrading my MacBook Ram from 2GB to 4GB. I've had a look around various websites, forums etc. to find out how much Ram my Mac can hold but it seems to have given me conflicting advice. The Mac is from late 2006. It has Intel Core 2 Duo, 2GHz, 250GB and currently has 2GB Ram. If anyone could give me an answer I would really appreciate it :-)
Thanks.

I sure do. Try OWC orDataMem

For a new imac how much ram should i get?

If I buy a new iMac, I see that one can get it with 16GB or even 32GB RAM. dMy 2007 iMac has 4 GB now after I upgraded? What would the difference be?

My 10 cents worth:
The minimum configurable amount of memory of a new iMac is 8Gb But...
If you are looking at a new upgradable iMac, absolute do NOT buy the Apple RAM upgrades at the time of purchase. It is grossly overpriced, and although good quality and reliable (I've been led to believe) you can buy just as good, if not better for a lot less. I wouldn't look further than OWC (http://eshop.macsales.com/shop/apple/memory/) or Crucial (http://www.crucial.com/). Both offer matched pairs and kits that are guaranteed to work with your iMac and as you will see, cost a lot less than Apple. Don't be fooled by the price, they supply good quality, fast memory.
Secondly, in terms of how much RAM, the question is, what is your budget? I always believe that if you can afford it (and memory nowadays isn't that expensive) max out your system and then forget about it because:
a) There's a fair chance that you'll be upgrading it again at some point if you don't max it out.
b) You are releasing the maximum potential of your iMac (in terms of memory performance, although the jump from 16Gb to 32Gb will not be as significant as the jump from 8Gb to 16Gb))
c) If you sell it, the extra RAM will be an attractive option for any buyer.

How much RAM should I add to my 2008 iMac?

Hi everybody,
I currently own an 20-inch Early 2008 iMac, and I was wondering what would be the best RAM upgrade for what I use the computer for. At the moment, I have 2GB of RAM and I'm running Mavericks, and I can tell that it isn't as fast as Snow Leopard. I use the computer for mostly video editing on Final Cut and sometimes iMovie, and also a little Photoshop here and there.
My question is: How much RAM should I buy (and from who) in order to speed up my iMac so that it can handle these programs without being painfully slow.
Thank you!

Your machine came with two 1GB RAM modules. The most it can take is a total of 6GB, by buying one 2GB and one 4GB module. Don't be tempted to buy these on the cheap, go with Crucial, OWC (macsales) or Ramjet. This will cost about $140. You will see an improvement if you only buy two 2GB ($65) and go to a total of 4GB, but I think you will see a significant additional boost by going to 6GB. The apps you are using can REALLY make use of all the RAM they have access to.

How much RAM do I need in my new MacBookPro?

I think I need to add more RAM to my MacBook Pro. I've been using it for a couple of months now and I'm tired of running so slow. Things are fine until I have several applications open or whenever I try to run any Adobe Creative Suite programs.
So, my question is: how much RAM should I buy? My 1.83 MacBook Pro has the standard 512 MBs of RAM that came with it. I'd prefer to keep the cost low, so would buying one more 512 MB stick be enough? I am processing 8 Megapixel RAW images in Photoshop. Will 1 MB total be enough?
Also, do I have to have the two slots matched? Can I put a 1GB stick next to my 512 MB stick?
Thanks,
Laura

512+512 is better than 1gb + 0 - because of the ddr2 effect in the same way that 256+256 is better than 512+0, but not better than 512+256
512 + 1gb is better than 512 + 512 because you have more ram which outweighs the performance benefit of the two dimms.
The way to tell is to run activity monitor (from applications), click and hold the dock icon and turn it into a memory pie chart. You'll see how much ram you are using (tip - free ram is the total of free (green) + inactive (blue). If you are only occasionally running right out you might get by with 1gb total.
Also, economically, you'll be able to get a 512 for about $45-50 as people upgrade, whereas the 1gb chip will cost (at the moment - over $100 for generic and $150+ for one that is the same model as Apple supply - these prices do change and right at the moment there is a shortage of DDR2. - If you do want to buy one, post back and I can give you some hints on where and what to look out for). I'm awaiting a machine next week and will be posting 2 512's on craigslist in your(our) region, as do many others who upgrade so it's not a bad way to get ram - from another mbp owner who is upgrading to 2 x 1gb - and it's normally been tested for a few days.
Also, not a bad idea to have a look to see which chip Apple have put in their already and post back.
Best of luck.
