Identifying which logic board I have

[jickerson]

Hi, I recently bought a mac pro to strip down for parts (mainly needed the logic board). It was an Early 2008 with a single 2.8 GHz processor. Long story short, ended up not needing the logic board so i'm going to put it out eBay. But when I was recording the serial number I noticed that the part number on the board was 630-7997 (and not 661-4449). After digging, i've found two conflicting sources for which Mac Pro model the logic board originally shipped with. One site said it's an alternate part # for the 2x3.2 GHz early 2008 model (whose standard part number is 661-4676), while another post said it belongs to the 2006 version of the Mac Pro.

Does anyone know which version of the logic board I have? If it is the 3.2 GHz version, would it be able to run the 2.8/3.0 processors? I'm somewhat concerned because I don't want to be accused of fraud/misrepresenting the board when I put it on eBay.

Seems that product number does match 3.2 one. It will run all SLAN* Harpertowns without problem. One of MR members is running 5472s on this exact logic board. Certainly not MP 1,1 part.

Certainly not MP 1,1 part.

So it isn't a 1,1? Is it an early 2008 or no?

1,1 and 3,1 boards do differ visually from each other, mainly by risers slots and northbridge location. Easy to recognize.

1,1 (and 2,1):

Thanks! This is actually what tipped me off to the fact it wasn't just a 661-4449
