4gb ram in june 2007 macbook?

I think they changed the CPU since the MacBooks for sell today have a 2.2 GHZ instead of a 2.6 GHZ the June 2007 MacBooks came out with.

I think Mort meant to say they now have a 2.2 GHz versus the 2.16 GHz sold back when you bought your machine. I think the graphics have gotten an upgrade as well.

Your MacBook would be able to use 3 GB of memory.

It looks like today's macbooks have been upgraded to the same core 2 duos as in the Pros with the 800mhz front side bus. It's this chip set that allows 4GB addressable memory. So check your profiler for your processor bus.

The core 2 duos with 667 according to Mac could only go up to 2GB, though OWC said they could address 3GB, of course according to OWC if you wanted to you could even put in 4GB into that set up, but would only gain marginaly extra performance.

So, if I have the MacBook model MB063LL/A it is a intel duel core 2.16Ghz I can only upgrade my RAM to 3GB? I called apple care any they said only 2GB.

according to OWC you can unpair them and go to 3GBs if you want they found no problems with workings. Apple still claims only 2GBS for those though.

PS: the OP should give Mort a helpful!

Apple officially only states 2 gb but here are some test with the different configurations of RAM with the MacBook such as yours.

MacBook Memory Benchmark Test

Is this benchmark test stating that the mid 2007 MacBook will support 4GB of RAM? Or, does it mean the Late 2007 MacBook with the 800Mhz bus?

Read the test carefully. The mid 2007 2.16 GHz model was tested not the 2.2 GHz Santa Rosa. The Pre Santa Rosa Core 2 Duo MacBook will hold 4 GB of RAM allowing it to meet the dual channel matched set mode. But it will only use 3 GB for general use. The SR Macbook will hold and use the full 4 GB of RAM. You can see the results from the test the different speeds attained with the different configurations. Some people on here have used 4 GB and some 3 GB. It is up to you on how much money you want to spend. I personally would get a matched pair and put 4 GB in. RAM is cheap right now and 4 GB of Crucial RAM can be had for less than 200 dollars. OWC and some other brands are just as good and cheaper I am just partial to Micron and Crucial which are the same manufacturer.

I have the older macbook and im really steamed that i can not upgrade to 4gb. grrrrrrr. why couldn't they foresee my dilemma in the design stages?!?
