Sorry haven't tried it, but what is everybody complaining about?? I've read a hundred posts now where people claims that the duron can't be overclocked by multiplier. But even though it may not be easy, it can be done. It's right there in front of you on top of the cpu! If AMD didnt want people to overclock they could have easily hidden these small contacts, and made unlocking the multiplier impossible as on any intel cpu. I'm buying a Duron and will try unlocking it. I'll make sure to post my results.
