Macbook Pro - 8Gb or 16GB total? I'm confused?

Postby Pitchfork » Sat Mar 03, 2012 10:45 am

I have the Macbook Pro 15" 2.2Ghz i7 with 8GB, and have been told that its the latest MBP from last April 2011.

Its a fast machine, but now I see on websites, and Mac Retailers that they are now bundling this Macbook Pro with 16Gb RAM?

So Can i go with 16Gb?

I'm looking at forums also and they say "Yes the MacBook Pro “15 2011 model (Model ID: MacBookPro8,2) can accept up to 16GB of memory."

Mine is :

Model Identifier: MacBookPro8,2
Processor Name: Intel Core i7
Processor Speed: 2.2 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 8 GB
Boot ROM Version: MBP81.0047.B24
SMC Version (system): 1.69f3
Serial Number (system): C02FK0V**** (should i reveal this?) lol

So surely mine is the same Model Identifier?

:roll:

Update : was told by a woman at Apple that this isn't possible with my model and 16GB, even though all the websites say that it is??

Anyway did a quick google to Crucial, and looked up my Macbook Pro :

"MacBook Pro 2.2GHz Intel Core i7 (15-inch DDR3) Early-2011"

Their specs now say :

"DDR3 PC3-10600
Memory Type: DDR3 PC3-10600, DDR3 (non-ECC)
Maximum Memory: 16GB
Slots: 2
Each memory slot can hold DDR3 PC3-10600 with a maximum of 8GB per slot."

Again this says 16Gb total? The Apple 'lady' said she thinks not?

Did i get someone's mum at Apple manning the online chat and she could be wrong? :crazy:

So according to http://www.apple.com/macbookpro/specs.html
it's 8GB max, but I'm not sure whether that's just because Apple don't supply 8GB sticks, or whether it's a genuine limitation of the system...

Hmm thanks, so now I'm confused as Apple say no (or not sure) but you might be right and it dooesnt support more than 8GB Sticks??

I'm still a bit confused?

@Neokoenig

Just done the crucial scan, with their own software and it says :

Memory:
DDR3 PC3-10600
Memory Type: DDR3 PC3-10600, DDR3 (non-ECC)
Maximum Memory: 16GB
Currently Installed Memory: 8GB
Total Memory Slots: 2
Available Memory Slots: 0
4GB
DDR3
4GB
DDR3


Each memory slot can hold DDR3 PC3-10600 with a maximum of 8GB per slot.*
*Not to exceed manufacturer supported memory.

This 15" system may utilize one of the following processors: 2.0GHz, 2.2GHz or 2.3GHz Quad Core Intel Core i7 processor.
Memory or DRAM is the 'working' memory of the computer. It's used to store data for programs (sequences of instructions) on a temporary basis."

So again this is saying it can take 16GB?

Are apple saying no, as you say because they don't do 8GB sticks, and they want me to buy from them, or is it cause of the compatibility issues? and stability?

Anyone else using 16Gb in MBP 2011 early 2.2Ghz i7?

Apple are even saying that their biggest fastest MBP on the planet :

17-inch: 2.4 GHz i7
2.4GHz quad-core
Intel Core i7

Apple are saying that this is maximum of 8GB which I find hard to believe, and I've definetly seen this for sale at Jigsaw24 etc etc with 16Gb?

It's quite common for Apple's official spec to give a maximum RAM ability, but have the hardware exceed this.

For instance, my old 2008 MBP has an official limit of 4GB, but it can actually take 6GB (but not 8GB, which doesn't work). And I have 6GB in it.

Do your research, ignore Apple (they are just quoting you the standard official specs), and if the general concencus of the internets says this machine works with XXGB without problems, then you should be fine.

Thanks Desmond, I had no idea about all this, and thought Apple was in stone..

16Gb on a Macbook Pro sounds good, and Crucial are saying thats the case! :D

So Can i go with 16Gb?
Do you really need 16Gb? Do you find yourself running out of memory with 8Gb ram?

Of course not Johnny! :D

But, I do run a couple of programs at once all the time (Ableton and Reaper) and also I run Parallels as a VM with Windows as another program, so if I can, and its stable, maybe for the price, the 16Gb would be beneficial?

I never just run say, Logic with plug ins, and thats it...

It's exceptionally rare that you'll need more than 8gb of RAM. Check your Activity Monitor if you're not sure.

If you don't already have an SSD, fit one in place of the optical drive - you'll see a massive performance increase for all sorts of tasks. After CPU performance, hard drive speed is the main bottleneck in modern PCs.
