Despite the LGA1151 socket, however, the CoffeeLake CPU series cannot run with 100/200 Series motherboards (Kabylake, CoffeeLake). This is primarily related to Intel's "banning" motherboard manufacturers from loading Microcode Coffeecode into older mobo BIOS versions.

The processors that are tested with stable operation include: i3-8350K, i3-8300, i3-8100T, G4900T, G5500T, G4900, G4920, G5500 and G5400T..
