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.
I’m not gonna sugar coat this, my expectations weren’t real great that we would be able to push our Intel Core i7-4770K as fast as we have been previously able to. I’m happy to say that I was wrong and we were easily able to push our chip as high as any of the previous motherboards that we have tested. Using Intel’s Extreme Tuning Utility we were able to bring the Intel Core i7 4770K to 4.8GHz @ 1.29 Volts without any issues!
We didn’t have to tweak to many settings in the Intel XTU software to hit 4.8GHz. Using the latest version of the Intel XTU software we set the voltage mode to static, CPU vCore to 1.29 Volts, and the CPU multiplier to x48 and we were rocking along at 4.8GHz with no issues at all!
