In this respect, the Golden Edition Z77 board delivers the maximum stable clock speed for my test station Core i7 3770K, adjusting only voltages for the memory, CPU, and memory controller. The CPU required 1.285 V with vdroop control disabled for a final voltage of just over 1.3125 V. The memory voltage was set to its specified 1.65 V and the memory controller was set to 1.05 V. Then the bclock multiplier was set to 46 and the bclock was adjusted to 102 MHz for a final clock speed of 4.68 GHz – a nice healthy 1.2 GHz over the baseline 3.5 GHz.
