Overclocking

Overclocking the new Haswell series is a bit different than overclocking an Ivy Bridge CPU.
Users have the ability to breach the BCLK limit of around 106-107 MHz on Ivy Bridge, making a frequency of 130 MHz a real possibility, which has as an effect on higher memory frequency as well.

Like before, the frequency is determined by BCLK (Base Clock) x Multiplier; 35x100 MHz for the stock speed of 3.5 GHz or 39x100 MHz for 3.9 GHz with the help of Intel's Boost technology.

For our tests, we overclocked by adjusting the bclock in order to force a multiplier of x35. The maximum we achieved was 120MHz with a voltage of 1.2 V.

We would have liked more than 4.5 GHz out of that chip, but it did not like the voltage.

Here is the maximum frequency we got:
