However, Xeon has a certain advantage -- it supports registered as well as usual non-buffered memory. The former is slower by 5%, and it's more expensive. Different options are available though -- for example, non-buffered DDR3-1333 memory modules (4GB) are three times as expensive as some registered memory modules. In return, you can install up to 32GB of registered memory (versus 16GB of non-buffered memory). For two, such memory is supported even three memory modules per channel -- good news for those people, who bought (or going to buy) P55-based motherboards with six slots (like Gigabyte P55-UD6). Considering the present prices, 24GB of memory in this case will be less expensive (almost by one and a half) than non-buffered memory for LGA1366. It's pennies from heaven for some users. Just make sure your motherboard does recognize registered memory -- the controller is integrated into a processor, of course, but we have seen compatibility problems many times.
