Intel Fourth Generation Core i7 4790K Review

”Before I started overclocking, I had high hopes that Devil's Canyon would do much better than Haswell in the clock speed department thanks to the improved thermals and power supply work. Sadly, I found that its Haswell roots run deep and ultimately limited my overall clock speed to 4.6GHz. I was able to run the ring ratio as high as 45 while keeping the clock speed at 4.6GHz. Running higher speeds was possible with some jaunts to 4.8GHz, but the voltage needed to reach the number was not worth the effective cost to get there over the long term. 4.7-4.8GHz is great for some quick and dirty benching, but not possible on this particular chip even running under water. At this time, I have to surmise that overclocking on the Core i7 4790K is going to be the same as we get when overclocking any Haswell chip. As the third Haswell-based chip I have tested, I have seen a 4.5GHz, 4.6GHz, and 4.7GHz chip, confirming my suspicions. I can't fully condemn overclocking on Devil's Canyon, but it will be the luck of the draw as much as it was with Haswell.”
