Intel Core i7-7700K @ 5.0 GHz OC PRETESTED

This piece of silicon has been thoroughly pre-tested with our Elkim extreme overclocker, guaranteeing a maximum frequency of 5.0GHz when using all of its 4 cores and 8 threads.

How to get a better CPU?

A silicone lottery? One of the main features of today's processors is that no two pieces are the same. The differences in the final frequency after overclocking amount to hundreds of MHz above the base frequency. While one CPU doesn't get past the maximum of 4.8GHz, a different one can achieve up to 5.3 GHz.

Hi, my job consists in finding hardware limits and pushing them forward. And I do that using even the most extreme methods of cooling, such as liquid nitrogen, which can reach up to -196°C.

The right choice of components for our top CPUs

The combination of well-chosen components is the basis for high frequencies. You can read our tips on how to achieve the guaranteed clock rate further below.

Vodní chlazení NZXT

A powerful cooling is the alpha.

This processor has been tested and cooled using the NZXT Kraken X62 .

Use a high-quality thermal paste

A quality thermal paste is equally important. We recommend the Thermal Grizzly Conductonaut or Kryonaut.

ASUS MAXIMUS IX APEX

The right chassis is the omega

Top processors deserve the best components! The differences in voltage:frequency demands of various motherboards can amount to dozens of millivolts. Based on years of experience, I would recommend the mid-range to high-end models from the Republic of Gamers line by ASUS. We test our CPUs on the ASUS MAXIMUS IX APEX .

Seasonic Prime 1200W Platinum

The right juice

A quality power supply plays the lead! A good and stable voltage for your motherboard makes a world of a difference. We test our top CPUs on the Seasonic Prime 1200w Platinum. When it comes to power supplies, it is not so much their total capacity that matters but rather their quality and overall design. For overclocking, I personally recommend the Seasonic power supply. The latest Prime series is especially good for the purpose of overclocking.

Our tips for achieving the guaranteed clock rate

  • Set the kernel voltage settings to manual mode in the UEFI to achieve a more effective power supply than the offset and adaptive mode can offer.
  • In the External Digi+Power Control settings, use ASUSdesek LLC level 6, to prevent unwanted voltage drops that could interfere with the overclock stability.
  • Kaby Lake processors are highly temperature sensitive, so use quality AiO water cooling size 240mm or better and a high-quality thermal paste. The stronger the cooling, the better the results. The cooling also depends on the airflow inside your case, meaning that if the airflow isn't optimal, the processor cooler won't function properly either.
  • A quality power supply that provides stable and accurate voltage is absolutely essential. We recommend the Prime series Seasonic power supplies.
  • The overclocking of our top CPUs requires at least some experience and basic understanding of the issue. Keep in mind that turning an overclocked system into a stable mode is no plug and play and requires patience and effort.
  • All processors have undergone at least 1 hour of the RealBench stress test by ASUS, which uses AVX instructions, among others.

Final recommendation

In order to achieve the guaranteed clock rate, it is imperative to follow our tips as close as possible. Keep in mind that you may fail to achieve the guaranteed frequency with an imperfect combination of components. The differences in the motherboards amount to dozens of millivolts, which goes hand in hand with the increase in processor temperature and the demand for cooling as well as the overall performance.
