Motherboard manufacturer ASRock confirmed on Twitter that Intel’s new six-core Coffee Lake CPU’s will not support motherboards using the Z270/170 chipset.
No?Coffee Lake CPU is not compatibilble with 200 series motherboards.

Earlier this week, the specifications for the i7-8700K, i5-8600K, and i5-8400 were leaked, and were listed as using the LGA 1151 socket. This is the same socket used by Skylake and Kaby Lake chips, and fit on Z270/170 motherboards. This move by Intel forces those who would want to upgrade their existing Skylake/Kaby Lake processor to a Coffee Lake one, to buy an entirely new motherboard.


Thank you intel but no thanks for killing these well working motherboards!
