Power Consumption and Overclocking

Power Consumption

The Kaby Lake Core i7 7700K consumes less power than the Skylake Core i7 6700K, despite the higher base clock and turbo clock speeds.

Overclocking Kaby Lake isn’t any different than Skylake and far easier than Haswell or Broadwell. If you have time overclocking Sandy Bridge, Ivey Bridge, or any of the newer AMD CPUs; you’ll find Kaby Lake is much the same.

I was pleasantly surprised to find a 5 GHz overlocking preset in the Gigabyte Z170X-UD5 TH when I updated the BIOS to a Kaby Lake compatible version. So for the first overclocking run I let the BIOS do the work via that preset. OOne click and the system was running at 5 GHz with 100% stability. Very Nice.

Now it’s time to see how far I could push the Core i7 7700K.  After I adjusted the line load calibration to its stiffest setting, I started bumping up the multiplier and then the core voltage. I alternated between them until I reached 5.3 GHz. At that point the voltage was at 1.44v. It felt like the chip would go higher, but I think the motherboard just hit the wall. The system was stable though and I had an ear to ear grin.
