Can the Macbook handle 4GB of RAM?

[phungy]

I searched but couldn't find the answer, if this has been discussed I truly apologize.

I know the MBP can handle 2GB sticks but I was wondering if the MBs can handle 4GB (2x2GB)?

I know this may seem overkill but I'm curious.

Thanks!

No.
The MacBook, the CoreDuo MBP, Mini and iMac will not recognize 2 Gb SODIMMs.
(well, one guy got his MB to recognize a single 2 Gb by clocking it down or something, but it crashed with anything in the second socket, so it makes no odds against 2 x 1 Gb)

The Core2 Duo MacBook Pro and iMac C2D only will go to 3 Gb (1 Gb + 2 Gb), You can physiclly put 2 x 2 Gb into but even then only 3 Gb will be recognized in OSX, and only 2 Gb in Bootcamp/Windows IIRC.

Thanks

To be exact, if you put in 2x2GB modules you only get the benefit of 3.2gb, so it is not worth it

That definitely helped, Thanks guys!

is this a software limitation or hardware?? cause I know some of the older ibook ram restriction were surpassed later on with a firmware upgrade.

Intel chipset limitation, even Windows users are stuck with the same mobile 945 chipset limitations.

It is a 32-bit chipset with the hardware DMA addresses mapped directly on top of the normal memory space -- can't do anything about it.

The OP was asking about a MacBook, specifically. If you put in 2 x 2 Gb it won't boot.

What about the C2D Macbook (not pro). I've read some places that you are able to put 2x2gb

I'd like to see those sources, because I've never heard of it working. (As CanadaRAM said in his first post...)

well can the c2d macbook handle 3g then?

 

[WildCowboy]

From what I've seen, no.

MacBook is up to 2GB. MacBook Pro is 3. It's all on the spec pages on Apple.com
