6GB in MacBook (Pro); Yes it works. - 8GB... well...

so apple should release a EFI update for the late 2008 unibody macbook 2,53 and 2.8 models to adress/use properly 8 gb of ram?
Maybe with SL it will be supported , anybody knows?

i would almost bet it will be.

all macbooks / pros that were unibody will support 8gb via update and or snow leopard.
 
I was just about to start a thread on this, because I pulled the trigger today on a refurb 2.53, and then realized that when 8 gigs of ram becomes affordable, I may be unable to use, it getting me to rethink my deal. but hopefully if nothing else snow leopard will fix this.
 
Hmm - is 8GB working now - the Apple store thinks so...

Looking at the apple store I clicked this link which is under Accessories Memory. There were 2 options for Macbook Pro, Current and Previous models.

Mine is a Nov 2008 2.8 GHz model and everything above 2.4 falls under current according to the store.

http://store.apple.com/us/memoryfamily/ME_MBP

All the Macbook's I selected offered 8GB as an upgrade option.

So from what I could see anything above 2.4 GHz seems to support 8GB according to the store. I must go into an Apple store and see what they think.

In the meantime does this mean that this issue has been resolved? Can anyone confirm this?

Unfortunately No

(Not sure what model you are referring to but mine came installed with 4GB as standard...)

OK - spoke to Apple sales today via their telephone number and was told it's all to do with the logic board installed in these machines. Their 'custom' chipset cannot address more than 6GB. Seems a shame but there it is.

So the maximum is locked at 6GB.

This Apple guy also told me that even though Snow Leopard will be able to address more - these machines will be limited to 6GB.

Anyone tested 2 x 4GB DIMMs? Is there a slight performance increase with a matched pair even if 6GB is the limit?
 
Maybe I'm missing something here, but why don't you call tech support at Macsales.com 800-275-4576 and be prepared to give them your Mac info (Apple > About This Mac > Get Info) to determine how much RAM your computer can handle?

There can only be one model given the April 2007 purchase date and spec—and that model's limit is 3GB and 3GB even if you install 4GB.
 
whats the RAM status with MBP 2.6GHz machines? Mine was the last of the "classic" 17 MBP's built in October 2008. Model 4,1. Back then the nod by this thread was 6GB RAM was ok. I install a 4GB stick + retained one of the 2GB's from Apple and the 6GB RAM has been working flawlessly ever since.

Has this changed since? -- Does anyone know if I can install another 4GB stick to bring it to 8GB without any performance issues. I'm using DDR2 SDRAM 667 MHz memory
 
You see the funny thing is; I've read through the whole thing but it seems that these three things never came together in the past 7-8 months:

- The owner of an unsupported [!] Santa Rosa or Unibody MBP limited currently @ 6GB
- A copy of a current Snow Leopard build
- 2 x 4GB of DDR2 or DDR3 RAM.

I myself am on a Penryn MBP happily running 6GB for about six months now.

I really wish I had an *extra* 4GB G.Skill (which NewEgg does not seem to carry anymore) *lying around* :rolleyes:

The only bit of real info we have is from an Apple Tech claiming that Apple has basically crippled the chipset itself which is kind of mean and corporate!

By the time 8GB is affordable and there are actually apps that take full advantage of it, you'll probably be ready to buy a new MBP. I know I will. I am very pleased with this refurb 2.8!

Cheers,

Apparently RAM is a lot less expensive at macsales.com (OWC). I am just about to order 6gb (4 + 2) from them for $190.00.
