CPU showing as 1.2GHz when I bought a 1.6?

[Drango]

I'm building my very first computer. (newbie alert!). Bought the Fry's ECS K7vta3 with a 1.6 GHz Duron combo kit. Just did the smoke test and loaded drivers and XP. System Information and the start-up screen is showing it as a 1.2 Duron? Did Fry's short me, or do I need to change a Bios setting?

the newer duron are 266fsb (133ddr), yours is currently running at 200 (100ddr) up the bus speed and voila!
