XMP profile dont work

[ Edited ]

Hello,
I bought a BLS2C8G4D26BFSC memory kit for my GA-Z270N-WIFI motherboard and i5-7500 Processor.

When I turn XMP profile on BIOS (ver. F4), nothing changes and if I disconnect the PC from the power supply (After a correct shutdown) computer will no longer start without resetting the BIOS.

What I'm doing wrong? Or is the memory module faulty?

 

Memory

The cpu-z screenshots are completely the same in both states (XMP on / off).

 

Thank you very much for the answer.
