Hi all, I'm new in forum . I have been reading previous messages to try overclock I5-6400 on MSI-Z170A-KRAIT-GAMING, I installed the lastest version E7984IMS.A6T and try to modify stock values. I've been able to change Extreme Memory Profile (XMP) to Enabled and CPU Base Clock (BCLK) and fail reboot because I have not been able to change Ring Ratio and CPU Ratio over 33 stock. Has anyone been able to overclock non-k CPU with this motherboard? Thanks to all. PD:Sorry for my bad English, I'm Spanish .
