Desktop Llano Overclocking
 

Overclocking on the Llano platform, by any stretch of the imagination by using this A75 Extreme6, would take ages to get a hold of and become a master. There are three main areas to overclock - the CPU, the iGPU, and the memory. But the Llano chip design is such that the CPU will only ever have a maximum TDP. If you increase the CPU and fix it at a new higher value, the maximum GPU will decrease to level the change out. Thus, if you're on a GPU limited situation (such as a modern game), then your overall frame rate will decrease.
