I don't understand this?

Um' well, I understand the idea behind overclocking a CPU and infact used a machine for several years that had been overclocked by a friend of mine who was an INTEL engineer. That was 1998 or so. So here is this video, but I don't understand what they are saying about it. Does it mean that they are running a 300 Hz chip at 5000 Hz?
