I could have asked this on another thread, but it was off subject. So, I was reading a post that hinted that the SR MBP is able to support 8 or more gigs of ram. Is there a limit on the Santa Rosa chipset, or is it that 4gb ram sticks are too much? Thanks for any help!
 
The Santa Rosa chipset supports 8GB of RAM. Apple only offers and upgrade to 4GB because going up to eight would be way too expensive (if Apple charges $750 to upgrade from 2 to 4, I don't want to know how much they'd want to go from 2 to 8GB...). In the future, though, you should be able to use 8GB.
 
Thanks for the quick replies. I don't know if I will ever need 8gb, but it's cool to know that I will be able to have that much.
 
So, I was wondering if Windows XP via Boot camp had any problems recognizing 4 GB of ram?

If anyone has 4 GB of ram and uses Windows XP please let me know as this is the only thing keeping me from the complete and total upgrade to 4 GB.

You're going to need a 64-bit version of Windows in order to do that.
 
Yeah the only problem with 64bit Windows is that iirc not all of the drivers are available on Windows x64.

While it is possible to install 64-bit (x64) Windows operating systems on Intel Macs with Intel Core 2 Duo processors, the Windows x64 OS encounters difficulties with full driver support in Boot Camp. The basic hardware used in most Intel Macs have drivers available for various OSes, including x64 versions of Microsoft Windows. However Apple specific hardware such as the built in iSight camera, Apple bluetooth, Apple track pad as well as software enhancements like Apple keyboard mapping and the screen brightness utility packaged with Boot Camp are written solely for x86 versions of Windows XP SP2 and Windows Vista and thus they do not work in the x64 versions of Windows.

The maximum amount of memory that can be supported on Windows XP Professional and Windows Server 2003 is 4 GB. However, Windows Server 2003, Enterprise Edition supports 32 GB of physical RAM and Windows Server 2003, Datacenter Edition supports 64 GB of physical RAM

Windoze x64 Edition supports 128GB of ram, but as others said, driver and app support are really awful.

windows xp 32 bit has a 4gb limit, but a portion of this is reserved for your graphics card ram and other things, so if you install 4GB of ram you will only be able to access about 3.0-3.5 GB of it. It's up to you to decide if that's worth it.
 
Thanks for the help! So what I understand is that on windows 32-bit I can have the 4 GB installed but I won't get the full 4 GB to use, but it will still work.

Mine shows 2.98 GB of RAM when running XP via Boot Camp.
 
I wonder if montevina's DDR3 support will allow one to install 4 GB DDR3 sticks...provided they become available this summer at a reasonable price (<$300 for 8 GB)

I think they have updated bootcamp guys as i installed vista 64-bit without any problems with drivers and they all came from Macbook Pro disk one and everything works!!!
 
Do all 2.4 ghz macbook pro's have the santa rosa chipset?
I've never really done anything that has made me think one way or the other about whether mine does. 8gb ram would equal heaven.

The Mid/Late 2007 and Early 2008 MacBook Pros both use the PM965 (Crestline [Santa Rosa]) chipset.

I am going out on a limb here (and I was right about the low end Early 08 MBP having a T8300), but I believe the updated MBP coming out late summer/early fall (most likely September) will not have DDR3. While the new model will have the Cantiga chipset (successor to Crestline), this new chipset supports "DDR2-667, DDR2-800, DDR3-800 and DDR3-1066 SO-DIMM." Furthermore, by looking at Intel’s plans for DDR3 implementation (see link below), one would gather that DDR3 is not set for the masses until early 2009. For these reasons, I do not think the Mid/Late 2008 MBP revs will have DDR3 and that this technology will be implemented by Apple with the Nehalem Processor update scheduled for early 2009. DDR 3 is still relatively expensive, even more so for notebook sticks, and 1 more year for prices to come down before it is distributed to the masses just seems like common sense.

Well Vista with SP1 should display the proper amount of Ram, at least it does on my HP, and with the marketing of the Vista 64 Bit OS we should see the introduction of more affordable 4GB Ram and dare I say 8GB Ram. Software companies like Adobe are already developing products for the 64 Bit OS. So those users who remember the XP x64 Edition which was supposed to be all the rave and had absolutely no support or software. Things should be a bit different these days.
