Q: How can I determine if this is the correct board to order?
A: The best way to determine this is to email us at email@example.com with your machine serial number, NOT the serial number of the logic board and sales will email you the correct part to order. You can also check your EEE code on your logic board. To be sure you are ordering the correct replacement part for your computer, make sure the EEE code of your existing logic board corresponds to one of the EEE codes listed below in notes.
EEE Code Note: All Apple logic boards have a special three digit "EEE" code embedded in the logic board serial number which positively identifies the part. Please note that this is the serial number of the logic board, NOT the serial number of the machine. The logic board serial number is on a tag which has the format "xxxxxxxEEEx". The "EEE" code is the three letters immediately preceding the last digit of the serial number.

The CMD chip on Rev. 1 logic boards is PCI646U2 and on Rev. 2 logic boards is 646U2-402. To find the location of the CMD chip on the logic board, click on the added image.
