As far I know, only nvidia nforce4 have support for this. But this may=20 get you into problems with lan and disk (SATA). And it's unbuffered ECC ram. So, I think you must choose between an anthlon64 non-ECC unbuffered=20 system or an opteron registered ECC system. I've both running: an asus AV8 Pro system and a tyan tomcat k8s. The=20 tomcat part is not too expensive. =2D- josemi > > (Yes, I've looked at the FreeBSD AMD64 mainboard webpage, > but it doesn't contain useful information regarding this.) > > Thanks in advance for any help and advice. > > Best regards > Oliver > > PS: I'm reading the list, so there's no need to Cc me.
