Editing Duron (section)

==Compatibility==
The Duron line was pin-compatible and operated on the same [[motherboard]]s as the Athlon line, requiring only a BIOS update in most cases. The original Duron was introduced with a 100&nbsp;MHz (effectively 200&nbsp;MHz) [[front-side bus]]{{snd}} the same as the then current Socket A Athlons. Later with the introduction of motherboard chipsets offering higher FSB speeds of 133&nbsp;MHz (FSB 266) and AMD's matching introduction of Athlon "C" processors supporting this speed, the Duron initially retained the 100&nbsp;MHz FSB for purposes of [[market segmentation]]. Later Durons were given official support for 133&nbsp;MHz bus operation only after the Athlon XP was used to introduce 166/200&nbsp;MHz FSB (FSB 333/400) speeds.
