Re: Alternative to a laptop?

Bummer, man. Too bad the mac OS ain't 64 bit like Vista....it won't be long.
 
It's basically not Intel's problem. They built the hardware to support the 4GB of RAM, even though the Mac OS prevents the hardware from doing what it was designed to do. Very common problem in the computer world.

I have the 7200 chipset, and it still exhibits this behavior.

There is more to it than this.  The BIOS and chipset can see the 4GB of RAM, but the 32-bit OS cannot use it without using PAE (which slows the machine down).

You must have 64bit OS, or you cannot access the full 4GB without using the PAE hack.

Here is my wife's response to the story, who happens to be Intel's Americas Marketing Manager for this entire product line:

Kris' Wife: "no - not anymore."

"if you really want the details of the memory addressing…read this document (page 55; section 4.4):  ftp://download.intel.com/design/mobile/datashts/31627303.pdf 

Bottom line is that the new 965 chipset (that is part of our new platform introduced in May, code named "Santa Rosa") supports 36-bit memory addressing which allows the overlapping portions to be remapped.  So there is no artificial limitation to 3GB on the Intel 965 chipset. 

The key is you want a platform with the 965 vs. the 945 chipset.  Another way to tell is if the Core 2 Duo processor number has a 7 in the first digit (i.e. T7700 for the standard voltage 2.4GHz processor).   

You'll note that you can configure the new MacBook Pros on the Apple site with either 2GB or 4 GB.  And a quote from that very same section of the configurator says "All MacBook Pro models support up to 4 gigabytes of RAM." "

Thanks very much! Did you say you had 4gig on your Toshiba?
