I live in Holland and it is not easy to find motherboards that (a)

Virtually all motherboards for AMD processors support ECC RAM because
the memory controller is in the CPU and all AMD CPUs support ECC RAM.
Than why is it that most AMD MoBo's in the shops clearly state that ECC
Ram is not supported on the MoBo?
All /OPTERON/ chips support ECC, unbuffered, non-registered in the case
of 100/1000 series, and unbuffered, registered in the case of
200/2000/800/8000 series.
I _believe_ all socket AM2, AM2+ and AM3 consumer chips (Phenom, Phenom
II, Athlon X2, Athlon X3 and Athlon X4) also support unbuffered
non-registered ECC. The AMD Specs page for the above processors
indicates I'm right about those CPUs.
I think what they're (the retail shops, that is) stating is consumer AMD
CPUs won't take the "server" (i.e. registered) ECC DIMMs.
A quick glance at ASUS's website shows that all current consumer (i.e.
socket AM2/2+/3) AMD motherboards from them support unregistered,
unbuffered ECC. I suspect it's the same for the other board makers, too.
