Question intel 300 series chipset motherboard

[Mavrix11]

Are 300 series intel chipset only compatible for 8th gen and 9th gen?? if so pls tell me how did my i5-7400 worked on my Asus Prime H310M-k R2.0, is it because of bios update??

depend on which 300 series 8th and 9th
go to asus support site to check the cpu supported list

you probably got the cpu wrong

I already checked it again and it say that it supports 8th gen processors. but I used i5-7400 and I don't know how did it worked
