Actually, if you could find a single 4 gig module, it is possible. Apple only advertises that they can accomodate 4 gigs total but the Santa Rosa platform supports up to 8 gigs of RAM. If you shopped around and found 2 4 gig modules, despite how damn expensive it would be, it would work.
 
stop spreading fause information guys, the SR platform that the macbook pro uses can support >8GB ram intel just havent certafied it yet because there was none on the market. Check the intel spec sheets.

This being the case, then when I buy my new MBP later this year, I'll be sure to go with a 2.2/2.4 to ensure this future expansion capability. Hard to imagine it today, but next year, not so much! :D:cool::eek:
 
One related question

On this note of what the MBP could theoretically support,

Has anyone tried to take a MacBook above 2 GB? In theory, this platform should be able to take more than 2 GB, unless Apple has capped the EFI code.

Max.

Yes many people have put in more than 2GB in a Macbook. You can go to 3GB or even 4GB but only 3.3GB will be used.

We've covered this many times -- See the Guide

The MacBook CoreDuo maxes at 2 Gb
The MacBook Core2Duo maxes at 3.3 Gb with 2 x 2 Gb SODIMMs installed.

Those limits will NOT be addressed by Leopard or Firmware, they are inherent in the motherboard's hardware memory controller. (speaking of spreading false information...)

no fause information spead on my behalf, napa on other platforms can sometimes run 4 GB ram just now. and i did not say that it will come i just said it may happen. Unlike whoever said it for sure will not support more ram on the SR as it most certanly dose support more acording to intel 8 or 16 GB is the SR limit but most likely 8 GB.

Read the specs of the 965 Mobile chipset on intel.com.. 4GB max.

see section 1.1.2.

(napa is the same btw (1.1.2))
 
this thread was done a few months back with intels document saying SR supports more ram than 4GB. im searching now to get the link to the document before.


here is the original thread, https://forums.macrumors.com/threads/334137/
Santa rosa dose support more than 4GB of ram.

Quote:
• Supports 8GB of Memory
The Mobile Intel® 965 Express Chipset Family supports a main memory
size up to 8GB.
SR is the Mobile Intel® 965 Express Chipset for support of 8GB ram. Why would intel make a new chipset that only supports 1 GB extra ram over the previous chipset.

Quote:
・ 36-Bit FSB enables full 4GB memory addressability and capability to scale up to 8GB memory (pending SODIMM module validation)

Is it possible to put a second Core2Duo processor into a MBP?

Umm... no. Where would you put it, for one thing? Unless you were to totally redesign the motherboard and add a second socket...

Is it possible for Apple to design a future MBP with dual Core2 processors? Unlikely, unless you like a 70 minute battery life and big honkin' fans...

no fause information spead on my behalf,
the 3.3 GB may go higher with leopard and a 64 bit firmware.
^^^
The 3.3 will never go higher on the non-SR as the motherboard and the memory controller map hardware addresses overtop of the addresses needed for the last 700 Mb or RAM space.
 
any idea when we'll see 8GB in a MacBook Pro/iMac? I'll be after an iMac with Montevina and wondered how much memory it'd support!

In the next revision of the core chipset, maybe. But only Apple and Intel know and they aren't telling.

As far as the current MBP and 4 Gb SODIMMs, so far Apple's developer spec says maximum 16 chips per module and maximum density of 1024 MBits per chip, so with those specs, you'd never get a 4 Gb module - you would need either 32 chips or a 2 Gbit density.
 
Curious

I am an owner of one of the original BlackBooks. I know that this guy was capped to 2 GB of memory.

I am not as curious as to the current lot of MacBook Pros and if they will take more than 24 GB, but I am curious of the new NVidia based MacBook series ( NVacBook? ) and what they can really take. As a heavy duty Parallels User, I would love to see 6 GB or 8 GB on my notebook. :D

Max.
 
I just found those 4GB SO-DIMM units today and wrote to Other World Computing, and they gave me the following reply:

We’re working on the 4GB 667MHZ So-DIMMs. First began testing over a year ago.... Issue has been one of overheating and in process of extended testing before we’ll release our own part. The MacBook Core 2 Duo models that use DDR2 667 can use them – but – under load heat is a problem and early modules caused total system shutdowns (they self powered down, the MacBook and MacBook Pros) with a cool down time needed before systems would turn back on. Once we have a solution we are happy with the heat profile qualification on – you’ll see us introduce them for the MacBook/MacBook Pros & iMacs. :)
 
5 Gb Ram Works!

I just received a 4 gb DDR2 module from G.Skill and this works fine in a :apple: Macbook pro 2.4 Core2 Duo.

I'm thinking about ordering a second one to make up for 8 in total!
