MP 1,1-5,1 Determine SMC Version of 4,1 / 5,1 Logic Board

[h9826790]

Ok - my problem is that my Mac is not working and I have to put in a new backplane. On the bottom of my machine cabinet I find the attached marking. And this picture proove that this computer is produced in 2009. I baught it in 2009 and nothing has been changed since then. So this made me order a logic board for a 4.1 mac that is upgraded to a 5.1. Necessary because I have dual 3.46Mhz processors installed. So now I am really confused! Will the SMC of the card I am to put in place be correct? Was the 2010 model relased already in 2009?

You reverted the logic.

A 2010 Mac can use any parts that already exist in 2009. This is your case.

Not a 2010 Mac was released back in 2009.
