dmw007 said:As far as I know, the chipset on the logic board limits you to 2GBs of RAM.
I think 1GB is soldered on the motherboard, leaving only 1 memory slot that can accommodate either 1GB DIMM or 2GB DIMM.garfield2002 said:I'm also curious of the 3GB limit, why not 4GB? I would think two RAM slots at 2x2GB makes more sense, well, if you had the cash. Perhaps one slot cannot physically accept a 2gig stick?
garfield2002 said:I wonder if some brave soul who is getting a C2D machine with 3GB to replace their Rev A MBP would be willing try their 2GB stick in it to make sure.
Incidently, the announcement made me look at 2GB RAM prices, I am just amazed at how expensive they are.

So much for 64 bit...skunk said:It's the same as with the iMac: you can put 4GB in, but it'll only use 3. A limitation of the C2D, I believe.
There's more to 64-bit than the ability to address large amounts of memory. It's a limitation of the Napa platform.ChrisG said:So much for 64 bit...

I was keen to try and get 3Gb in my 17inch macbook pro, so it looks like I will have to upgrade to only 2gb
I was wondering though, is there any way to check if your memory is running with both channels? And is there any whay to know which supplier's ram will work at dual channle with the RAM already in my mac book.
What is the perfomace loss from dual channel to just one?
Cheers
It's not going to happen. Ollllllddddd thread by the way.So from what I've read, the Intel 945PM chip CAN address more than 2GB, but the firmware on the logic board of a Spring 2006 MBPro was written for 2GB and no more.
It would be a nice present from Mr. Jobs if we got a Firmware Update to fix this...
I'm in college and can't really afford to replace this 4 yr old Mac at the moment.
Yet running Parallels is kind of important, and it crawls unless I shut down everything else.
