Intel Ivy Bridge Overclocking

Running the Intel Core i7 3770K Ivy Bridge processor with an Intel Z77 motherboard and HD 4000 graphics in a few different combinations. The i7-3770K on Ubuntu Linux was tested at its stock settings (3.5GHz, HT, Turbo Boost, etc) then with Hyper Threading disabled, Turbo Boot disabled, and then those features restored and the CPU then overclocked to 4.2GHz and 4.8GHz. Running Ubuntu 12.04 with the Linux 3.4 kernel for Ivy Bridge.
