How much maximum RAM does it take?

I was wondering how many slots are there and how much total maximum RAM it can take.

There are two RAM slots that you can fill with 4 GB RAM chips for a total of 8 GB. In the these series:

Only this series of the 17" MacBook Pro support 16 GB MacBookPro8,3

The older 17" MacBook Pro's MacBookPro3,1 only supports 6 GB of RAM

What happens if you try to install 16 GB of RAM in a model that only supports 8 GB?

I've seen before certain restrictions to be not true. Just wondering if that's just not 'recommended' instead of really not compatible. thanks!

This is the specs of my MacBook Pro:

  • Model Name: MacBook Pro
  • Model Identifier: MacBookPro5,2
  • Processor Name: Intel Core 2 Duo
  • Processor Speed: 2.66 GHz
  • Number of Processors: 1
  • Total Number of Cores: 2
  • L2 Cache: 6 MB
  • Memory: 8 GB
  • Bus Speed: 1.07 GHz

Here is the series your system is part of: MacBookPro5,2

The limit of your system is what the PCH can address which sadly is only 8 GB in this series.

You can install 16GB RAM in the 17" 2011 Macbook Pros if they have been updated to OS-X Mavericks (previously limited to 8GB max).

Here are the only 17" models that can support 16 GB: MacBookPro8,3

And have the latest EFI firmware!

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

Dan, Yes! forgot to mention that!! :)

Unfortunately, I wasn't able to do this. I have a mid-2010 15-inch MBP 6,2 with a 2.66 GHz i7, running the latest EFI firmware from Apple's official firmware page. The 16GB kit I installed (from Crucial, 2x8GB) either caused a kernel panic on bootup, a freeze on bootup, or would eventually cause sudden shutdown when more than 8GB was addressed after running normally for a little while. I've researched this for quite a bit, and I can't seem to resolve why some people have been able to get this to work, and others haven't. I'd appreciate any clues you might have!

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

You can now go up to 16GB with two 8 GB modules (very expensive) in the early 2011 models once you have updated the systems firmware.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

You can install 2x8 Gb RAM, for a total of 16 Gb.

It's ok. The MBP works fine (and quick).

My MacBook Pro is one of the MacBookPro5,2 series. I wasn't notified automatically about the EFI upgrade...

Although I upgraded to Maverick and I can see so much improvement...

I would DEFINITELY put more RAM tomorrow if i could...

I just can't know if mine will accept it or not... since the EFI hasn't been proposed by apple

Here's the link to the Apple TN EFI & SMC firmware updates for Intel-based Macs Double check your system, it maybe you have the newest already.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

And only the newer Unibody i5/i7 models can be upgraded to 16GB the older models can't. I would double check your system with Apple before you buy any modules. Do get a good name brand of module.

Plug in your systems serial number here: EveryMac - Lookup We can't use the last 3 digits any more to identify your system. Open the URL it offers up for your systems details and what it the RAM limit.
