What's the difference between Registered and non-Registered RAM?
Whats the difference between buffered and unbuffered ram?
There are two types of SDRAM module organizations, unbuffered (also known as unregistered) and registered. Registered modules have additional components (registers) placed between the incoming address and control information and the SDRAM components. These modules are typically used in Servers due to their added reliability (they place much less of an electrical load on the memory controller and therefore make it possible to have as many as 16 or 32 modules in a large system).

I am guessing that Registered RAM is more expensive. Am I right? Is Registered RAM used in normal Desktop PCs?
yes it is by about $25 per 256mb over the best normal ram. I think you can use it in a desktop but there is not much gained from using it. Also how much faster is pc3200 over pc2700? It is about 44mhz faster and the DDR rating is 77mhz higer:lookaround:. I can't use PC3200 though since i have pc2700 in here and 3200 would clock down to 2700:(

On the AMD 64 processors you're required to use registered memory. However unless you run a server, you'll see no added benefit.
