Overclockers reach 6.7GHz with Kaby Lake Core i7-7700K

Some Chinese sites have already gotten their hands on Kaby Lake-generation desktop processors. They were able to boost the Intel Core i7-7700K to 6.7GHz on liquid nitrogen, while boosting the Core i5-7600K to 5.1GHz on air.

According to Wccftech, the site HKEPC used a Core i7-7700K in combination with an ASRock Z170M OC Formula motherboard and Galax Hof ddr4 memory. With the bus speed of 100MHz and a multiplier at x67, the clock speed of 6.7GHz was put on the card, where ln2 had to be used to cool the chip.

FacebookHK managed to obtain a Core i5-7600K and pin it to an Asus Maximus VIII Gene motherboard. With a bus speed of 127.51MHz and multiplier at x40, a stable clock speed of 5.1GHz was achieved.

Expreview also has a Core i5-7600K and according to this site the pcb is somewhat thicker than Skylake, while the ihs also looks more robust. At Skylake, there were some reports that CPU coolers could bend the substrate of the processors because it was thinner than in previous CPU generations.

Intel is expected to introduce Kaby Lake processors for the desktop in early 2017. The first processors of the generation are energy-efficient chips in the U and Y series intended for laptops, 2-in-1 systems and mini PCs. Kaby Lake has not been provided with a new architecture compared to Skylake, but is a refresh of the 14nm generation.
