question of compatibility between the MB and Memory (ECC RDIMM )

Hello. I have a question of compatibility between the MB and Memory. Do the MB need to support memory type ECC RDIMM or is it the job of the memory controller in the CPU (xeon)?

Will this bundle work:

1) (motherboards on the b65, h67, b75, h77 and other desktop chipsets) + (xeon CPU)

or it must be

2) (motherboard on the C602..) + (xeon CPU)
