The only thing that you can break when OCing your CPU is... your CPU. Potentially your motherboard if you get a really shit one. Also, I'm fairly certain you cannot overclock on the H81 chipset?
Because the CPU is a joke in terms of power consumption some manufacturers have brought out BIOS updates for their lower end 1150 chipset motherboards that will allow ONLY multiplier overclocking.
