Logic Boards - 661-7373, 661-7101/7102/7103 whats the difference ?

[Sponge Bob]

Dear all,

I have a 2012 2.5" tapered screen iMac, EMC 2544, A1418, i7 Fusion drive version.

I need a new Logic Board since mine is burnt out.

I see these 4 different Logic Board part numbers quoted, and they seem the same. But there must be differences.

I have trawled the net to find out but I'm SOL.

Are there any of you smart people out there that can help with an explanation.

Many thanks

I think you mean you have a 2012 21.5" iMac with Fusion Drive. A 2.5" screen would be a bit hard to view.

As for the correct logic board, there very likely will be a difference between them as that model has various options for CPU and memory. You might want to go to http://www.powerbookmedic.com/?subid=29427&source=pjn and compare the part numbers. Off hand we aren't going to know that information.

(but none of these show an i7 processor...)
