As I understand it, the "new Athlons" will only be available
as socket A parts to the general public. Slot A parts will
only be sold to OEMs and will not work with with the KX chipset
in any case.
(This was my understanding anyway, perhaps I am wrong)

ECC is nice. We are integrating ECC capabilities in our monitoring
tool to detect possible problems.
