Can the 820-2054-A logic board be upgraded to 820-2101-A?

I accidentally got a 820-2101-A logic board from an A1226 MB pro to fit my A1121. It fits in the case and all but three component connectors fit. Can I upgrade a few more parts and make this work?

I doubt anyone has tried. Given the age of the system I’m not sure its worth fighting it out. How about returning the logic board and get the correct one.

Do keep in mind the NVIDEA GeForce 8600M GT GPU’s in the A1226 had major issues! So finding a good board is very rare today. NVIDIA GPU failure fallout continues, Apple extends warranty.

So I wouldn’t waste the effort as you likely got a bad board, or one that will fail very soon again!
