What are registered DIMMs??

Why are they required for certain processors? I want to build an AMD T-bird system and I have heard that you need registered DIMMs on DDR capable mobos.
 
Registered or ECC memory uses one clock cycle to double check the information it just wrote to itself. Typically, ECC memory is more expensive than non-ECC memory and a bit slower. Mission-critical machines such as large servers etc, use ECC memory. It is a bit slower, but more accurate. The casual or even power-user will not see a difference in performance between the two.
 
Check out this link. Most DDR motherboards do not require Registered DIMMS. On some of the boards, you need to use all Registered if you go above 2 modules but most boards only have 2 slots.

 
Thanks to both of you for the quick replies and information. I'll skip the registered DIMMs and just get some good quality PC2100 memory for my new mobo.
 
Also ECC can only handle single bit errors IIRC.
Registered IIRC can handle multibit errors.
One of them occurs at the Dimm level, the other requires some kind of partnership with the chipset, yeah?
Registered + ECC = Belt and braces 🙂
