Problem Upgrading RAM on MacBook Pro

I have a MacBook Pro (one of the first MacBook Pros) It originally came with 512 RAM. I upgraded my RAM by buying and installing 2 1GB Banks of Crucial RAM, I followed some instructions that I found online (both video and written) and the installation seemed to go fine - the laptop rebooted fine and it seemed to be working fine. When I click on the apple it shows the memory as being 2GB. However, every once in a while my laptop now automatically reboots and one time the screen went completely grey. Obviously I've done something wrong. Any troubleshooting advice would be appreciated.

put in your original install disk.
start the machine, while holding down command d
this will put you into the hardware test.
run the extended version.
this will check the integrity of all your hardware, including your ram.

Problems upgrading RAM for Macbook Pro 13" late 2011

First, thank you all for your assistance.
I don't know if this has happened to anyone yet. I have a 13" late 2011 MacBook Pro that came with a default 4 GB of RAM. I considered upgrading to 8 GB and problems arose: I had stripes 1 inch in lenght distributed across the screen. I've done some research and saw that it was a hardware problem with the Graphics Card/GPU. I switched back to the original 4 GB and so far so good, no problems. I did notice a few key things:
Originally I have 384 MB of Video Ram in the GPU
While using the 8 GB Ram upgrade, it said 512 (called my attention)
It reverted to 384 when switching to the original RAM
In the tech specs section of Apple Support site about my machine, it says that the Video RAM is "shared" with main memory. No other knowledge on that.
Could the RAM upgrade affected the memory supported by the GPU? Why did it increase? Is there any solution to this?
Thanks to everybody in advance.

It should - I've 16GB of RAM installed in my late 2011 15" and my built-in card now shows 512MB of VRAM. There might have been a problem with the RAM you installed. I would only buy Crucial, Kingston (not the 'value' brand), OWC or Corsair (again, not the 'value' brand).
Some RAM sellers simply have less than stellar performance using Macs. Make sure that you install the correct speed and specs as recommended by Apple.
Good luck,

Problem after upgrading ram in macbook pro 5,3 to 8gb

Hello.
I was trying to help my friend, to upgrade his macbook pro 5.3's memmory, from 4 gb to 8 gb.
We bought the cm3x8gsdkit1066:
Memory Configuration     Dual Channel
Memory Type                    DDR3
Package - Memory Pin     204
Speed Rating                    PC3-8500 (1066MHz)
Package - Memory FormatSODIMM
http://www.corsair.com/en/memory-by-product-family/value-select-memory-upgrades/ cm3x8gsdkit1066.html
As i see this, the memmory, should be fine, and suported, and the macbook accepts 8 gb as a max.
When the computer boots, it beeps 3 times, waits, and repeat it. I found this as a error code for the ram?
So my problem, what can i do to solve this problem? The macbook accepts the old ram, and boots up fine.
Best regards
Christian Holm

It may be that the RAM is not compatible or faulty for some reason. Have you tried to install it again just to make certain that it is seated correctly. If still no success, I would return it and get RAM from Crucial or OWC. They are the two vendors of failsafe Mac RAM.
Ciao.
8 Gb RAM for the mid 2009 MBP should cost about $50. If you paid the price on the link, you paid too much.

Upgrade ram on macbook pro 2010

I have bought two different brands (G.Skill and PNY) of ram for my Macbook Pro 13.3 2.4 GHz Intel Core 2 Duo (2010) trying to upgrade from 4GB to 8GB and both are not working. Meaning I followed the exact instructions, didn't touch the Gold and installed it the way I was supposed to. When I turn it on, it freezes. When I put the old memory in ( 4 GB 1067 MHz DDR3 ) it starts up fine. The new memory is 1066. . .could that be the problem? I've gone through two "ram finders" where you put in the different specs of the Macbook and it's brought up the exact same ones each time. The brand I got this time, PNY, said it was Mac Compatible. What am I doing wrong? And do I need the exact same brand that's already in my Macbook (Samsung) or is there a different brand that will be comparable?
Thanks.

It is always advisable to use the same brand for both the memory chip.
As you wrote you have one RAM stick from PNY and other from G.Skill that may be the cause of problem.
Buy both the RAM chip of same brand.
Hope that helps.

Upgrading RAM on MacBook Pro

Hi folks,
My boss wanted to upgrade his MBP 15" 2.4 GHz's 2GB RAM to 4 GB. I went to the Apple store for help, and was told they only work on fried RAM - but they sold me the memory module and showed me the step by step guide.
We followed the step by step guide to the letter, but now that the new memory is installed, it's only recognizing one slot. When we run system profiler, it comes back with the message
BANK 0/DIMM0 Empty Empty Empty Empty
BANK 0/DIMM1 2 GB DDR3 1067 MHz OK
The same thing happens even if we switch the slots that the RAM is going into - and when we reseat the original memory sticks, it only recognizes 1 GB.
Could we have caused the slot itself to go bad? Is there some sort of diagnostic I can run on it without having to take it back to the store, to see if it is the slot? ...if it is, dare I ask how difficult it is to get fixed and how much it tends to cost?
Thanks in advance.

Hi, I have the same problem when trying to update my memory in my MacBook Pro. I installed the new 2x 2GB memory cards and it does not matter which slot I put the memory in the MacBook Pro will not boot when both cards are populated. I removed the 1 GB card that was in slot 1, I installed both 2x 2GB cards and the system would not boot. I removed the card in slot 0 and the system booted and showed that I have 2GB in slot 1. I then tried to insert the original 1 GB card in slot 1 for a total of 3GB the MacBook Pro again would not boot. I swapped the cards around thinking that there may be some order in which the memory needed to be installed. Again this did not work either. I verified that both slots worked, if I install the memory in slot 0 with slot 1 empty the MacBook Pro boots, if I install the memory in slot 1 with slot 0 empty the MacBook Pro boots. The question is, is their anything that is required for the MacBook Pro to recognized that I have memory in both slots at the same time and boot successfully. Any help would be greatly appreciated.

Trying to upgrade RAM on Macbook Pro 15" (Mid-2010).

Hi I have a Macbook Pro 6,2 (Mid 2010 / 15-inch) with an intel core i7 processor 2.66GHz, and I recently tried to upgrade my 4GB RAM to an 8GB RAM, after making sure online and from the tech specs that my computer can handle 8GB. Whenever I startup after installing the 8GB it stays stuck at the Apple logo startup screen, but when I put my old 4GB RAM back in it starts up normally, anyone know why?

Since it works when you use Apple's RAM, the problem is most likely the RAM you were sold. Unfortunately, all RAM isn't created equal so the vendor is an important part of the equation, both selling RAM that actually works with Macs and standing behind their product when it doesn't. This vendor does both.
See if you can get your money back.

Upgrading ram in Macbook pro 2 Model 8,3

I want to upgrade the RAM in my Early 2011 macbook Pro. I already purchased it. I bought CORSAIR 16GB (2 x 8GB) DDR3 1333 (PC3 10600). When I go to Apple's site to see how to install it says I can't put more than 8GB in this machine.I went to Corsair's site and plugged in the model etc. this memory came up as being compatible. I'm very confused. The Apple specs say this model supports up to 8GB. Does that mean in each slot or total. I will loose $ if I have to return these, but I don't want to harm my computer.

Glad I could help.

Upgrading RAM on MacBook Pro 13" to 1 Slot of 4Gb RAM

Please help,
I want to upgrade my MacBook Pro's RAM. Currently I have 2Gb of RAM, one 1Gb on the top slot and another one 1Gb in the bottom slot. I want to upgrade to 4Gb of RAM so that I only use one 4Gb on the top slot.
TechSpecs:
Model Name: MacBook Pro
Model Identifier: MacBookPro5,5
Processor Name: Intel Core 2 Duo
Processor Speed: 2.26 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB
Memory: 2 GB
Bus Speed: 1.07 GHz
Boot ROM Version: MBP55.00AC.B03

I thought if I was only going to use 1 module, I should put it in the bottom slot.
It doesn't matter which slot you put it in. If you put it in the bottom slot, you won't have to remove it first if you decide to add a second one later. But why on earth would you choose not to use both slots now, when you have modules to put in both? 5GB of RAM is better than 4GB.

Upgrade RAM for MacBook Pro (Retina, 13-inch, Late 2013)

Hi
Is it possible to upgrade the 8GB to 16GB RAM for the above mentioned macbook pro?

The Retina display models cannot have the ram upgraded post purchase...the ram modules are soldered to the logic board.

Upgrading RAM on MacBook Pro (October 2008)

i have 2gb of ram currently.
i was wondering whether i could buy 2 4gb sticks of ram
will the laptop recognize 8gb of ram
i have read that it only recognizes 3gb
i need to know
thanks

Just for clarification, you can upgrade the early 2009 models of the 15" Macbook Pro to 8GB of RAM. As long as you have the 2.66 or 2.93 version (or any subsequent model) then the same 8GB upgrade kit sold for the 17" Unibody will work (I'm typing this now on a 2.66GHz 15" with 8GB installed). Whether or not this configuration is officially supported as of the time of this writing is unknown but there is no technical limitation to prevent it from being done, unlike the earlier models (2.4, 2.53, 2.8) which do not support anything over 4GB (the OS may see it but it won't run reliably).

Upgrading RAM on MacBook Pro 2009?

I have 2GB DDR3 on my current MacBook Pro. Will any DDR3 work for upgrading? Can I buy 2 more 2GB DDR3 and have a total of 6? Sorry if this makes no sense but I have no idea.

You can use any RAM that meets the specifications set forth in your user manual. Good sources include Data Mem and OWC.

Upgrading RAM on MacBook Pro 7.1 13"

Hi, I have a 13" MacBook Pro from Mid 2010 - I believe that is the 7.1 model (2.4ghz), and I am looking to upgrade the RAM.
Having had a look through I have seemed to find out that this model can take up to 16GB (2x8GB) DDR3 1066MHz RAM.
Can someone please confirm if this is correct, and if so can you please advise the best place to purchase such memory (online in the UK)?
Many thanks for your help.

Officially it supports 8GB of RAM, but you can update to 16, Take a look at this link http://support.apple.com/kb/SP583
I am not sure where purchase in the UK, but take a look at this link, http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3

Just make certain that the RAM meets the specifications for your MBP and seat them firmly. Directions are in your users manual. Kappy is correct.
