For this test we used a motherboard designed for overclocking, GIGABYTE Z97X-SOC Force, to allow our two candidates to scale properly without any artificial limits. For LN2 tests we used the Corsair Dominator 2x4GB 2400MHz CL9, while for the other scenarios we used the Team Zeus 2x4GB 1600MHz CL9 (to fit nicely under the monster Noctua NH-D14).

While the use of a skinned Windows XP 32bit would have been nice talking strictly about benching, this article is not just about that. We are talking scaling and stability starting with plain aircooling and finishing with LN2, so to make the article relevant also for the average home user we used Windows 7 64 bit for all tests. For each scenario (except LN2) we tested the stability with at least 10 minutes of Prime95 64bit using all cores, a light single threaded stability with SuperPi 1M and the absolute maximum frequency with a CPU-Z validation.

Now there is one more thing – as I said, this review is read by die hard overclockers but also beginners. So before we show you the results for each cooling stage we will also briefly explain it with a simple language, so everybody can understand. Forgive us, die hard fans, but everybody started from somewhere and needed to learn…even you…even us. So be patient and bear with us.

    16. You had to go up to like 1.35V or higher to get your 4790k to almost 4.8ghz?
      I set my BCLK has high as it would go at stock (101.5), set voltage to 1.30 fixed, set multiplier to 50, knocked it down until it would boot (48), knocked it down to temperature within operating ranges (47), and then tweaked the voltage down until it stopped, then set it to Adaptive, with a max of just above where it stopped.

      result: 1.23V 4770.5MHz

      Then I bumped CPU Cache till it wouldn’t work anymore, at 45x.

      Max temp at 86 degrees. No matter what I set voltages to I can’t get it to operate at 48x without it constantly going into thermal throttle. Works fine at 47x.
      I can even get it to do 48x on one core, so long as I don’t start up GTA V.
