Intel Z97 Overclocking

Overclocking greatly varies due to what hardware is being used and who is doing the overclocking. Always remember that no two pieces of hardware will perform the same, so our results will differ from what you might be able to get.


The Intel Core i7 4770K runs at a non-turbo speed of 3.5GHz and turbo will ramp the processor up to as high as 3.9GHz under a lightly threaded load as we can see above. Since we are using a K series processor which has an unlocked multiplier we will be able to increase the default x35 multiplier to achieve our overclock today. This is the easiest way to overclock K series processors and should provide us with some great speeds.

Opening up CPU-Z to see where the Intel Core i7-4770K was sitting, and found it sitting pretty at 4.7GHz! The only aspect of this overclock that has me worried is the CPU VCore, its sitting at 1.42Volts. The Intel Core i7-4700K ES I use doesnt require that high of a voltage to overclock typically.
