In an unbuffered (non-registered) architecture, the address signal from the memory controller is sent to every RAM chip on every DIMM module. As you increase the number of banks and increase the load on the memory controller, the signal of the memory controller deteriorates from the ideal square-wave to a sine-like wave where the signal rises and falls slowly, lengthening the signal. This can cause timing errors because the chipset will try to read a data signal that is not yet completed. With a register, the memory chipset only addresses the register chip – one load rather than 16 ones. On the next RAM clock cycle (half a system clock cycle since it is DDR), the register will send the signal to the RAM chips on the module. This ensures that the communication between the memory controller and RAM are timed precisely. The disadvantage is that there is a slight performance hit and only certain chipsets support/require registered ECC DDR-RAM.
Think of the register as the person at the front desk who’ll relay your message. If your voice is loud enough, it’s quick to yell to the entire factory. Otherwise, it’s better to pass your message to the front desk, who can then directly pass it on to the recipient.
The other way to think about it is that, as you add more and more memory to a regular system, memory timing needs to slow down. With registered DIMMS, you just have a fixed register latency, but the other timings can run tighter. In other words, if you run a system with only a little bit of memory, buffering will slow you down. If you have a a sytem with more banks of memory, not only is registered DDR more stable, it's also faster.
For this server-grade reliability, the Athlon 64-FX and Opteron are designed for registered ECC DDR-RAM, just as non-i875P Xeon chipsets are. While all registered DDR memory is ECC (due to marketing/practical issues), all ECC memory is not registered.
