Intel Chipset Z370 Coffee Lake Block Kaby Lake Processor Through Firmware?

Posted on
The incompatibility of the upcoming 8th generation Intel Core (Coffee Lake) processor against the commonly used processor motherboards, seems to require consumers upgrading to think ahead of time with the new motherboard purchases.
In essence, be it an upcoming 8th generation Intel Core (Coffee Lake) processor and 7th generation Intel Core (Kaby Lake) processor allegedly both empower motherboards with LGA 1151 socket. However, in reality both processors use a chrome-chip motherboard different, the next-generation Intel Core (Coffee Lake) processor will use Z370 chipset motherboards instead of Z270 berchipset motherboards commonly used by the 7th generation Intel Core (Kaby Lake) processor.
This of course instantly invite big questions for many people. On the one hand there is an assumption due to power requirements on Intel Coffee Lake that makes the Z370 motherboard can not work with Kaby Lake CPU, while on the other side there is also a suspect due to differences in the BIOS system used.
According to people at Guru3D, some motherboard manufacturers have stated privately that there is no physical reason for Z370 berchipset motherboards not supporting Kaby Lake given that the Z370 and Z270 chipsets have similarities. With only firmware restrictions, Intel reportedly has blocked Kaby Lake processor to run on Z370 chipset motherboards.
For anyone who has been comfortable using the Z270 / Kaby Lake rig foundation is unlikely to rush to upgrade the rig to Coffee Lake. But even if the decision is there, maybe they will see first the reshuffle of its platform rather than just have to replace the CPU.

Meanwhile, recently several partners have reportedly also revealed that the extra pin used on the Z370 motherboard is more intended to transmit the required voltage to the Coffee Lake CPU. It’s not entirely clear if the upcoming Coffee Lake will be compatible with Z270 motherboards that have similar BIOS blocks. Intel seems to be getting interested in separating its platforms, although technically there is overlapping compatibility so far.
