My memory is 4gb for my macbook pro what is ram??

My memory is 4gb for my macbook pro what is ram??

RAM = Random Access Memory
the 4GB you quoted is your system memory, people say get as much as you can as it attributes to the performance of your system with major impact.
other people disagree..

2010 13" MacBook Pro upgrade 8GB RAM, Startup issues

After upgrading my 2010 13" MacBook Pro to 8GB RAM, it doesn't return from sleep when opening the lid. I have to actually press the power button at least twice to wake it up. Then it shows a status bar as if it's waking from hibernation.

Can my MacBook Pro run this ram?

I am looking to upgrade from the original RAM that came with my MacBook Pro when I purchased it last year, it has 8GB, and I want to upgrade it to 16GB as I am always using absolutely all of it, well about 7.8GB of it. I have the early 2011 17" MacBook Pro with the i7 CPU.
Now I have been looking to purchase this RAM because it is 1600Mhz instead of 1333Mhz that I currently have. From what I have read it will run at 1600Mhz without a problem. But I'm just double checking to make sure this would be good RAM to upgrade to, I am looking for as high quality RAM as I can get.

What are your thoughts and suggestions for RAM?

For what it's worth I have a LATE 2011 17" mbp and it's essential to use 1600 ram! And, it works beautifully.
Here's a post I posted elsewhere ...
Hey guys,
Hopefully this will help. With a late 2011 17".
THERE IS NO PROBLEM, AT ALL, RUNNING 1600 SPEED RAM.
(1) I have a very late 17" macbook Pro. (It is actually the somewhat rare 2.5 quad model.) One of the very last ones made.
(2) It comes with 1333 ram
(3) I swapped in 1600 ram
(4) IT IS ABSOLUTELY CERTAIN, THAT, THE MACHINE RUNS MUCH, MUCH, MUCH, MUCH, MUCH FASTER when you have 1600 speed ram.
(Indeed, it runs 1600 / 1333 = 1.20x faster on all memory operations - it's just that simple and obvious. It's strange that some are suggesting there will be "no difference" etc. The difference is VERY SUBSTANTIAL -- like 20%)
I did A NUMBER OF TESTS back-and-fore swapping the slow and fast ram.
and it is very, very obvious, the speed difference.
Most operations on computers are just memory bound - everything from startup to rendering and the like is quicker - obviously and clearly quicker - with faster ram.
(5) I have had utterly no problems running the faster ram. It reports and runs the ram utterly normally, no problem.
(6) These machines cost thousands, and ram cost a few dollars - there seems very little reason you wouldn't do this.
(7) I do have one of the very last 17" mbp. (It was "old new stock" - I bought it unused in March 2013.) So, it's possible that OLDER 17" mbp will not run 1600 speed RAM. But, I mean it costs like $100 to try, on a fantastic machine worth $1000s, so it's a huge win at low cost if it works.
I hope this helps future readers!!!!
Cheers

Slow brand new Macbook pro- almost all ram being used up!

I just purchased my first mac a few weeks ago- a 13 inch macbook pro running snow leopard. I have been experiencing surprisingly slow performance- computers older than mine or others of the same model quickly multitask while I frequently sit watching the pinwheel spin. This problem seems especially evident when browsing. When using firefox or safari, when several tabs are open scrolling through pages is slow/delayed and opening new tabs freezes the computer for several seconds.
This occurs with only a couple of other programs open- maybe only itunes and ical for example. Meanwhile older and equivalent computers appear able to run even more programs simultaneously without such slow performance.
Using the Activity Monitor- it appears that 1.9 of my 2 gigs of ram are being used up. This seems unusual to me as not much is running. I still have 70 gigs of hard drive space available and have been keeping up with software updates. CPU is 89% free/idle.
Any suggestions or explanations for a new mac user? This new computer is rivaling my old PC running winodws xp in how slow it can run.
Thanks

The same thing happened to me when I upgraded my older Mac Pro to 10.6. It turned out one process, #112 "coreaudiod," was using almost 100% of the CPU time. Use Apple's "Activity Monitor" in your Utilities folder to find out if you have a process using up the CPU.
In my case, I deleted "com.apple.audio.coreaudiod.plist" from the launchdaemons folder in the system library, restarted the computer, and that solved the problem.

Macbook Pro 2014 (16gb ram) running very slow in excel. Can anyone help?

My Macbook Pro 2014 is running extremely slow in Mac Excel 2011. I just recently made the purchase (Last week) to upgrade from my Macbook Pro 2013. The upgrade was for work as I handle large spreadsheets in my new role. It would take some time to load before, and I was told it was because I only had 4GB of RAM. Now, I have 16 GB of RAM and it runs slower than before. Can anyone assist me with a solution?

Can I upgrade my Macbook Pro to 16GB RAM

I am a Graphic Designer and use some very heavy bound software for rendering and running multiple memory munching applications everyday.
Lately my macbook pro has been increadibly slow. I have seen allot video on youtube of people upgrading their rams to 16GB. I was wondering of my mac can operate that too.
The upgrades I will be doing are:
500GB SSD h/d
2x 8GB RAM
- My only concern is the RAM size compatibilty. Please let me know if its viable. Also if theres any other upgrades I can do feel free to share. Thank you.

Can anyone confirm if the new MacBook pro ram user upgradable to 16gb or it has to be done at the factory?

My Macbook Pro now 10GB RAM is this Flex mode?

Hey everyone, I just upgrade my Macbook Pro Ram. So the default is 2GB + 2GB = 4GB RAM now I took one 2GB stick out and install 8GB RAM in the slot. Now my MAC is 10GB RAM. It run so smooth, but I don't know if this Dual Channel, Single Channel or Flex. Someone told me this is Flex mode because I have 4GB Dual Channel and 6GB single channel. Is there any program to check which channel? By the way my Mac is 15 inch, non-retina, 2.3Ghz, Late 2012 but I bought in mid-2013 Haha.

Macbook Pro 17 inch RAM limitation?

Hi, I am using MBP 17inch 2.5GHz core 2 duo. I wanted to upgrade my ram from 2GB to 4GB, so i bought 2x2GB Kingston ram, DDR2 667Mhz. But when i installed both, my computer does not start up! but when i replaced one of the new 2gb ram with the older 1gb ram, making a total of 3gb, my mac could start again. So my question is there a limit to the ram capacity??

I have exactly the same problem and i've heard that you need to upgrade the firmware version...
The problem is that i don't know how to do that so i can't tell you that it works.
Help's welcome

MacBook Pro out of RAM when nothing is running?

Okay so I have a brand new 13 inch non-retina MacBook Pro with a 2.9 GHz i7 and 4GB of RAM. I understand when I am running a game or FCPX why I would get close to or run out of RAM, but as I'm typing this, the only thing I have open is Google Chrome and Activity Monitor. I am using 3.99 out of 4.00 GB. I am planning on upgrading to 8GB soon, but is this normal? I have restarted and that doesn't help me. Here is a picture of Activity Monitor:

It most certainly is normal with Mavericks. Please read this:

RAM usage under 10.9 id different than with priors OSX's. Do install the additional 4 GB RAM but relax regarding the current usage.
Ciao.
