Hi folks,

I have a MacBook I bought sometime in late 2006 which seems to be the transition period between the models that could handle either 2GB or 4GB total ram. Not sure which one I have, any way to tell whether I can upgrade mine to 4GB by looking at the model# or something?

The specs are:
Hardware Overview:

Model Name: MacBook
Model Identifier: MacBook1,1
Processor Name: Intel Core Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 2 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: MB11.0061.B03
SMC Version: 1.4f12
Serial Number: RM*
Sudden Motion Sensor:
State: Enabled

I'm running OS X 10.5.6 on a 200GB harddrive.

I hope I can upgrade. I'm loading large charts and every time I wanna do something it comes back saying Java doesn't have enough memory to do this or that. Will increasing my L2 cache help? If yes, how do I do that?

thanks a bunch for helping me out on this one

    Your computer can handle a maximum of 2GB RAM. The configuration which could handle 4GB and access 3.3GB was a Core 2 Duo with the identifier MacBook2,1.

    Will increasing my L2 cache help?


    That can't be upgraded.

    Although Apple states that this model MacBook is capable of 2GB's maximum RAM, I have this exact model with 4GB's. However--your system profiler will show all 4GB's of RAM but OS X will only address 3GB.

    This is my one-stop-shop-all for Mac--That's how I knew I could do this!

    OWC - It's one of the best.

    Your model is a Core 2 Duo Mac; the original poster is using a Core Duo Mac, which isn't the same model as yours.

    However--your system profiler will show all 4GB's of RAM but OS X will only address 3GB.


    That's only true for the Core 2 Duo configuration; it isn't true for the older model, which is limited to 2GB.

    Hi krp2nte: I believe you will find that the OP has a Core Duo MacBook. Your signature states that you have a Core 2 Duo. Yours will accept 4gB and utilize 3gB. The OPs computer will accept 2gB only.
