Is there a correlation between CPU and serial number on 6,1?
A while back I bought a 6-core on eBay that was still eligible for AppleCare so I bought it and registered it w/AC.
After getting a great deal on an 8-core CPU E5-2667 V2, not an Apple shipped option) I did the upgrade, and suspect that the 6-core D300 was itself upgraded from a 4-core.
Is there a way to tell from the serial number or any other way? Wondering in case I need to ever get a repair done.
