If you go to you can find latest bios update however before using the new Intel 4th Gen Core processor, Asus suggest that you first download the BIOS updater for new Intel 4th Gen Core Processors and then update the BIOS using this tool. If you show all in bios, scroll down to bios updater and follow instructions.

[Update #2]

I fixed the problem

1) I Started the motherboard with a compatible CPU, with a clean Windows Installation and of course with the old BIOS version v1405.
2) Installed the Intel Management Engine interface v9.0.0.1323 (is obligatory this version or the ASUS Bios Update Utility don't go to work either with a lower o newer version is exactly the IME programmed to run)
3) Started the BIOS updater for New 4th Gen Intel Core Processors selecting the current BIOS version and update it!
4) Finally! the motherboard recognize the i7-4790

this is the only way to run the motherboard and similar series of ASUS with +4th generation of Intel Processors no matter what you do this is the proper method
