Happily running 2200 on mine. I just updated a week ago. There's a 2202 now? Jeez...
Simplest method is to use Asus EZ Flash 3 if your motherboard supports it. Look in the BIOS under Tools for Asus EZ Flash 3.
Edit; I just looked at specs for your board. You do have Asus EZ Flash 3.
i know bro about asus ez flash but dude say i can flash via bios flashback but i can't find flashback on my motherboard 🙂
