With six cores and 12MB of L3 cache on a relatively new 32nm process, it's not surprising that we weren't able to push our Core i7 980X too far. At stock voltage I was only able to reach 3.5GHz with turbo mode disabled using the stock cooler. I could get the system into Windows at ~3.7GHz, but not stable without additional voltage.

3.5GHz - Max overclock with stock cooling and stock voltage
Giving the chip extra voltage let me go up to 4.13GHz without sacrificing stability.

4.13GHz - Max overclock with stock cooling at 1.359V
