4 GB RAM Sticks

I am curious about this too. In another thread (sorry I am not able to find it at the moment) somebody was mentioning that you can put 4GB RAM modules in the MBP but the issue is having 64-bit software that will actually use it. So it sounded like this person was saying the MBP will actually recognize this amount of RAM. Though I have to say CanadaRAM's argument sounds far more likely.
 
Ah, found the thread and the post.

So According to Jiddick, the SR MBP can take 8GB RAM, maybe more. Although this idea seems in direct contrast to CanadaRAM's statement. How does one find out exactly how much RAM Santa Rosa will take? I've been checking the Intel site, but the closest thing I could find was someone's speculation:

"Apple is currently selling 3 GB Macbook Pros and will surely go above 4 GB max when Santa Rosa is available."

Where do you find specs on Santa Rosa? Typing in Santa Rosa specifications in Intel's Search box was no help.

I am definitely in the "won't believe it until I see it" camp. Currently the specs on the Apple SantaRosa machines state that the maximum number of chips on a module is 16 (2 ranks of 8) and the maximum density per chip is 1024 Mbits. Consequently, the maximum module size is 2 GB.

In order to get 4 GB on one module you have to be able to recognize either 2048 Mbit density chips, or 32 chips. That's the only way.

If the particular memory controller cannot recognize 2 Gbit density devices, then it's game over for 4 GB modules.

One more question, how did you find out this information about the density recognition?
 
4GB+2GB= 6GB (Montevina) Possible?? Could be!

Better yet 4GB+4GB= 8GB =D

That's what I want to see in Nehalem (Quad Core modesl).
