Hi there!
Indeed, the Haswell cpu has Intel Turbo Boost built in...weird. Do you have the FreeDOS version of the laptop or did it come with Win8 pre-installed?. If you do have the FreeDOS version, I suggest you install windows again and see how it fares..if not, then...I dunno. Maybe install Intel XTU and search there for an answer. I saw that there is that turbo boost power max..maybe that can do the thing..
