NVIDIA 680i Chipset Can't Handle Quad Core Yorkfield

@ 2007/11/23

IT HAS LONG-RUMOURED on Internet forums, but now a moderator at EVGA forums has appeared to confirm that Nvidia's Nforce 680i chipset fails to support all 45nm processors from Intel. In a weird flashback to Nforce4 SLI shenanigans, with its lack of compatibility with the Pentium D 820, the tide has now turned on the Nforce 680i. It seems Nvidia ran into some compatibility problems with upcoming Intel processors. It declined our request for a comment on the matter earlier today.

680 was launched just after 965P I am pretty sure, around Fall 2006. So 975X was still going strong, and 965P was there getting bugs worked out. Then came P31, P35, & X38 while 680 was out. 780 will have P45 and X48 to play with. It doesn't rain for Nvidia, it just pours chipsets.

Now what is obvious is Intel will be launching new chipsets for Nehalem. But what about Nvidia, any word on their Nehalem chipsets yet? INQ reported Intel traded Nvidia the info they needed to design CSI capable chipsets...

780i = 680i rev A2 + br-04 chip afaik

From what I've read, 780i should have no problem with Yorkfields or Wolfdales, 680i "could" be made to work with Wolfdales, but almost defintately not with Yorkfield.

I agree that you cannot really blame it on nVidia, if they didn't have sufficient info than they cannot make anything happen. However, the comparison to Intel is not entirely right : Kentsfield (for example) did work on 975 and 965 chipsets, it just didn't OC very well... 945 and 955 chipsets however were quick to be abandoned, but at that time I don't think 680 was around either.
