I believe the Intel Xeon E5345 SLAEJ Quad Core 2.33GHz 8MB 1333MHz Socket 771 Processor will work in the cMP 1,1. I've read up on some threads here, and do I need to worry about two of these pulls being from different machines? It makes sense to me that as long as they match the chip spec, any revisions or anything shouldn't matter. Should I pull the trigger on a pair of these from Amazon? Do I only need to upgrade to the 2,1 firmware only to have the CPU properly identified by the system?
