Is it possible to overclock the AMD C-50 APU

I was able to overclock and undervolt using k10stat. CPUz confirms overclock and undervolt. Additional battery life also confirms undervolt, but I'm uncertain if the overclock is accurate because benchmarks show only a small boost in performance even when i boosted the 1ghz cpu to 4ghz... Also, I am aware that 4ghz from a 1ghz seems unbelievable, but there is a bit of performance boost and CPUz does confirm the overclock. Maybe someone can use this to come up with a better solution.
I hope that helps.

Yes sir you are. I used this program called Brazos Tweaker I was able to get my C-50 up to 3.9 GHz rather than 1 GHz. As the person above said, CPUz confirms this overclock. i could also get a picture of it if you need to see for sure. BTW: its quite stable and helps game performance.
