ASRock Z77E-ITX 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 3770K utilizes a Bclk of 100MHz, under full load the Intel Core i7 3770K uses a multiplier of x35 to achieve the final clock speed of 3.5GHz. 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. The Intel Core i7 3770K has a turbo multiplier of x39 which will cause the system to run at 3900MHz (100MHz x 39) with a lightly threaded application.

The ASRock Z77E-ITX UEFI BIOS allows us to load various presets for our Intel Core i7 processor. We can start out up a measly 4.0GHz overclock, or choose more aggressive overclocks. We can increase our overclock by 200MHz up to the maximum overclock of 4.8GHz.

By taking advantage of the Optimized CPU OC Settings we were able to hit a rock solid overclock of 4.6GHz. While using the ASRock Z77E-ITX mini-ITX motherboard we attempted to use the 4.8GHz setting, not surprisingly we weren’t able to run at 4.8GHz on our Intel Core i7 3770K.

Once we were done with the optimized CPU OC settings, we reset the BIOS and proceeded to see how far we could push our Intel Core i7 3770k. Once again we were able to bring our Intel Core i7 3770K to 4.7GHz. We weren’t quite sure what to expect from the ASRock Z77E-ITX when it comes to overclocking, we are definitely pleased with our results today!

Above we can see the settings that we had to change to bring our 3770K to 4.7GHz. We only needed to tweak three different settings. The CPU multiplier was increased to x47, the CPU voltage was increased by .06 in offset mode, and the CPU Load-Line Calibration was set to Level 1.
