LGA 771 CPU list: every Xeon and Extreme chip on Socket J

LGA 771 (Socket J) is the server and workstation socket Intel used for Xeon 5000-series chips from 2006 and for a handful of single-socket and Extreme parts. With an adapter sticker and the socket tabs cut, many of these Xeons run in LGA 775 desktop boards that already support the matching Core 2 core.

54 chips, fastest first. Each row opens the full spec sheet.
