Not necessarily, not even likely. The memory controllers in K8 could also deal with unregistered and registered DDR1 and later DDR2. The mainboard (BIOS to be precise) nails down which one is required.

You have a point that FB-DIMMs are overall unlikely. It's probably too complicated to put a memory controller onto the die that does unreg and FB-DIMMs. And it isn't as required as it was for socket 771 because now you can have one memory bank per CPU, avoiding the huge bank mess that 771 ran into.

That still leaves registered or unregistered as choices.
