Apple officially endorses 8GB of RAM for some 15 inch Unibody MacBooks

Thu, 03/26/2009 - 7:46am — Cleve Nettles

AI found Apple unceremoniously selling 8GB kits for its newer model 15-inch Unibody MacBook Pros (not the older 2.5GHz model). It is the same kit as they sell for the 17-inch unibody Macbooks and it is the same price. $1200. If you have to ask...

Not to worry though, hardcore RAM fiends, OWC has the same kit for a paltry $719. Amazon has it for just over $1000.

This RAM upgrade is also compatible with the "Early 2009" iMacs.

So my 2.8GHz unit and the older 2.53GHz unit won't be able to get the 8GB treatment? Hmmm....

$1,200? That's Absurd! What I

$1,200? That's Absurd!

What I don't get is the most expensive 2GB chip is $50. Even IF its 2.5 times to make a 4GB chip, that's $125 a chip! Times two, is $250!?!? Not $700 - $1200?!

Expect that price to drop rapidly once 8GB laptops are the norm. Too bad Intel can't get their crap together with the chipsets to allow 8GB+.

That's cool, but it's not like my 4 gig MBP is slow or anything.

@ Wei-o

True but nice to know you can turbo charge it (when the price comes down) Might mean I go longer before I replace mine (Although when it comes to Apple I am very weak!)

What about the 2.4GHz 15" Unibody?

So if it is compatible with the 2.53GHz machines, what about the 2.4GHz Unibody model?

Who's right..it does or it doesn't work!

8gb compatibale with 2.53? Why didn't it work before when people tested it out with 8gb and couldn't work but only worked with 6gb. This doesn't make sence.

Is it the memory different that Apple offers?
Is Apple offering an update that I don't know about for the 15".

The real reason why the new 15'' MBP support 8GB

Hi, I think I know why Apple is able to offer 8gb ram support on the revised 2.66 MBP and not on the 2.53 or 2.4 MBP.

Take a look at this:

15'' 2.4-2,53 NVDA Chipset

17'' NVDA Chipset
http://s1.guide-images.ifixit.com/ig...YbiIuTLL.large

There are TWO different revisions. The first is B2 and the latter is B3.
I think that the former does not support 8GB of RAM and the latter does. That explains why the 17'' has support and now the NEWs 15'' also have, Apple gave the 15'' not only a speed bump but also the newer revision of the chipset!
