Just put in a new 2600k on an asus p8z68-v pro motherboard, and i have been monitoring the frequencies. When idling, it operates at ~1.6 ghz, when put under any type of load, even when using all cores, it goes up to ~4.4 ghz. I did not purposefully overclock it, I expected it to just range between the listed 3.4 and the single core 3.8. Why is this happening, and will it be detrimental to the system over time?
