Hello. I was running my i5 6600k at 4.4ghz perfectly fine, temps were low, after i updated my bios on my gigabyte z170 gaming 5, my cpu clocks went back to stock. I went into the bios and set the ratio back to 44, voltage on auto like i have always had it. After i save the settings and pc proceeds to load windows i get blue screen with the error "clock_watchdog_timeout". If i put the cpu clock back to stock i get no errors, and if i lower to 4.3 from 4.4 i get no errors. Does anyone know why im not able to oc again to 4.4ghz without getting blue error screen?
