Most mobile processors are locked meaning no overclocking. Typically a laptop doesn't have a cooling solution that would allow for much if any additional heat that overclocking would bring.
One is base clock the other is max boost speed. Your processor already manages and does do this. So you are already getting exactly what you were specced.
That will be a max clock and only on one core and typically isn't held long at all. You're far more likely to see continuous operation more near the base clock. One are where that sporadic rise of a core to full boost is helpful is gaming.
i have the exact processor and the overclock is automatic. it can go up to 3ghz and when more power is needed is automatically engages the turbo boost and it can go to a maximum of 4ghz
