Swapping 1.3ghz Logic board for a 1.8ghz or 2.0 Logic board

Original Post: 13 inch Macbook Air A1466 Mid 2013 to 2014 model

Hello all

I have a 'liquid spill' 13.3 inch Macbook Air A1466 model , i5 , 1.3ghz , 128gb ssd, 4gb ram which doesn't power up.

My thoughts were to source an exact replacement board 1.3ghz

However I have not found any, but I have seen a lot of A1466 logic boards with a 1.8ghz or higher processor on it.

Would these logic boards fit into the Macbook Air A1466 chassis correctly if I were to buy one?

Are all the screw holes and main connection points situated in the same places on the 1.8ghz boards as is for them1.3ghz boards?

Thanks in advance.

Liquid spills usually short out the keyboard and power button. Only 50% of the time does it get to the logic board. I replace the keyboard first, then see if the logic board is working.

Hello Mayer, the keyboard has been tested as ok. A repair technician has tested the logic board and a replacement is needed. The liquid reached the logic board. Thanks for the reply.


If you stay with the A1466 model boards you should be OK. I'd also try to get the same year model board.


I've spotted a few variations of the logic boards for the 13" A1466 Macbook Air. They seem to be ranging from 2012 to 2014.

Having looked at the pictures of the boards they all seem alike.

Yet I approached one seller on ebay about their item, being a 2012 1.8ghz i5 4gb ram 820-3209 A. Whereby they replied back and told me it was unsuitable ?

The 2012 board is a 820 - 3209 A & the 2013 board is a 820 - 3437 B.

Is there any way of finding a compatibility chart for Apple logic boards?


Generally you can't switch out to different series logic boards in your case here you can go up to the 2014 MacBookAir6,2. Sadly, there is no 1.8 or 2.0 GHz board that fits your system. Here are the Apple part numbers for each system of this series: MacBook Air 13" (Mid 2013) 1.3 GHz Logic Board - Apple P/N:661-7476 (4 GB) , 661-7477 (8 GB) and MacBook Air 13" (Mid 2013) 1.7 GHz Logic Board - Apple P/N:661-7478 (4GB), 661-7479 (8GB) and these: MacBook Air 13" (Early 2014) 1.4 GHz Logic Board 661-00062 (4 GB), 661-00063 (8 GB)


Thanks Dan.

The (2012) 820 3209 A & (2013) 820 3427 B from the A1466 family are very similar, however the 3437 B has 1 more connection point that the 3209 A doesn't have. Just where the DC jack I/O board would plug into the logic board.
