Overclock AMD Athlon 64 6000+ on an Asus M2N68-AM?

[Magnosian]

Hello MajorGeeks! I'd like to say that hopefully the fact that I just registered and this is my first post won't make me less.. qualified of asking.

So, to the question. I'd like to overclock my CPU, which is a AMD Athlon 64 X2 6000+. I've tried going into BIOS but it seems that it's already at the maximum. But to be sure, I ask you guys here.

My motherboard is as stated in the title; an Asus M2N68-AM. I've tried using ClockGen but it seems that my motherboard isn't supported by it, thus making me unable to overclock with it, or am I missing something?

If there's anything else that is needed, I'll gladly give you the information.

Thanks, Magne.
