So does the new MBP support more than 4gb - officialy

barefeats said:
I put dual 4GB modules in an "early 2008" MacBook Pro. It saw all 8 GB according to Activity Monitor but it ran really slow -- like it was confused -- especially when I ran Compressor with 2 instances or After Effects in Multiprocessing mode (which spawns two sub-process that use 3GB each).

I went back to dual 2GB modules and it ran at normal speed again.

I'll be trying it again with the "late 2008" MacBook Pro. One of the memory makers is sending me samples. I'll report back.

Any chance you can try 8 GB in a MacBook (Santa Rosa)?

6 GB seems to be a working configuration in the MacBook Pro but not 8 GB.

I find it hard to believe they would go back from a 64 bit chipset to a 32 bit one

Well when they went POWER to Intel, they went from G5 to Core Duo. This was 64-bit to 32-bit, albeit single to dual core. Not for notebooks, but still, they did so.

That was a fundamental change in system architecture, where there was little alternative, and in any case it was only the G5 iMac (max ram of 2.5GB btw) that was affected in this way.
 
Ok, so after reading this and the fact I'm getting a new MacBook soon I did some searching in the Internet. I was quite surprised Google results were not what I wanted (only links about Apple's announcements to 9400Ms), so I went directly to the source, Nvidia.

So while I searched the Nvidia website I found the following link: Click Me

I am not 100% sure that is the chipset used in current MacBooks, but its as close as I could find in Nvidia's website. Plus, many of the features here match what Apple has listed (DDR3, 1066MHz FSB and RAM speeds).

So if anyone would care to interpret I am sure we might find an answer to the debacle of whether current Nvidia chipsets can make 8GB Ram possible.

Sadly there's nothing there to interpret. I've looked myself on nVidia's site for more detailed information. We're going to need a more detailed datasheet on the chipset.

Apple hasn't put up the developer notes on the new laptops, yet.

No, I'm saying that Apple never used a 64bit chipset on it's notebook line. Pre Santa Rosa notebooks show 3GB of RAM when 4GB is installed.

6GB show of MBP could very well be with PAE, which is an Intel tech. nVidia's new chipset may or may not have it.

nVidia chipsets have supported more than 4 GB of RAM with a 64 bit CPU and 64 bit OS for a few years now. (i.e. XP 64 bit and Vista 64 bit). The best thing to do for anyone doubtful of this is to download a Geforce 9400 desktop mobo' manual and see.

[EDIT] The Geforce 8300 (The AMD equivalent of the 9300) supports 8 GB. However this is a desktop mobo and not a laptop mobo.

"4 x DIMM, Max. 8 GB, DDR2 1066/800/667 ECC,Non-ECC,Un-buffered Memory
Dual Channel memory architecture"
 
Can someone with a 9400M Macbook Pro acknowledge that all 4 GB are available (MMIO getting 256/512 MB graphic VRAM out of the way)?
