DailyTech reports AMD Opteron 2200-series work fine in Quad FX motherboards:
AMD insider and occasional DailyTech writer Dave Graham posted images of an AMD Opteron 2218 processor running on an ASUS L1N64-SLI motherboard. This is intriguing as the ASUS L1N64-SLI is a motherboard designed for AMD’s Quad FX enthusiast platform. The motherboard BIOS detects the processor correctly and functions properly.
It also appears that the system is using standard DDR2-667 MHz memory instead of registered ECC memory typically required by Socket F Opteron-based motherboards. Although it would seem memory compatibility problems would arise, Graham has images of the system passing Windows Vista’s memory diagnostic tool without error.
