[sllug-members]: AMD processors and memory types

[Jarom Hatch]

I'm looking for an understanding here....

Reading up on the differences between socket 939 and socket 940 CPUs 
shows that one of the differences is that socket 940 memory controllers 
require registered memory whereas socket 939 use unbuffered memory.  I 
have also read in places that socket 939 "requires" unbuffered memory. 
If the latter is the case then why does my system, which is an Athlon 64 
3200+ work with the registered memory I have installed (and recognize it 
as such)?

On the other hand, if it is true that socket 939 CPUs can use either/or, 
then why does the socket 940 memory controller have the advantage, being 
it *requires* registered memory?

Couldn't find an authoritative answer on the web...  May not even find 
one here...  :)
