13" Macbook Models Compared -
MacBook Model vs Features Chart
Maximum RAM by Configuration
              

HERE is a brief summary of the maximum RAM that may be added to each 13" Macbook model. There are OVER 26 Macbooks in the 13" format. Let me see YOU try to get them straight.





I created this chart because I found it extremely difficult trying to understand how much RAM can be added to each 13" Macbook model. There is no consistency in the Apple numbering system, which drives me crazy. Even the charts from Apple are incomplete, and have errors.

#4 Example Configuration =

13"/D2.0G/2x512/120/SD-DL

Notes -

1. Max RAM = 3 (only 3G of 4G available)
2. ** All models are "Intel Core 2 Duo", except
the Early 2006 Model which is "Intel Core Duo"

The "EMC" number is not defined (Extraneous Machine Count?), and is only mentioned sporadically. There is NO WAY to look it up, and find out what it is, or what it means.

A1047 = G5 Models
A1181 = 13.3" Macbooks
A1278 = 13.3" Macbook Pro, and Aluminum model
Then there are the 15" models. Later, maybe I will tackle this.
Then there are the 17" models. Later, maybe I will tackle this.

Note the 2 RED B's above. The Apple document shows them as A's. I believe that is incorrect.
Apple does NOT list Ordering Number MC061XX/B. Others do. Why is it missing from the Apple data?
