I have z420 motheboard and I bought e5 2640, but I've seen that z420 support this cpu from 2013 bios.

Problem is because that I never boot in bios before with i7 3930k and I dont know if its and old bios that wouldnt accept e5 2640.

So I need to boot in bios with e5 2640 and update to newest bios, if its possible to boot in bios with not bios supported cpu.

No, it is not possible to boot into the BIOS with an unsupported CPU.

He means you can't update the BIOS with an unsupported CPU.

 

You must use a supported CPU to update the BIOS. After that, you can to put your E5-2640 on your motherboard.
