I have a http://www.asrock.com/mb/Intel/H170%20Pro4S/ . In it's this description it says that it features a NON Z OC function for DDR4 RAM. But when i load the BIOS i don't see the advertised option. I updated the bios from the UEFI to latest one and still no such option apprears. Btw my BIOS screen is blue and on the advertisment it's red.
