Overclocking on the Intel Z390 platform is pretty easy. The easiest way to overclock would be up simply change the frequency divider in the BIOS. To achieve the best overclock we try to stay with the timings that the XMP profile recommends. If we run into any issues we will bump up the voltage to see if we can get our system to boot and become stable.
The XMP profile puts this kit at 3200 MHz. In the BIOS I started moving up the frequency divider without changing the timings or voltage. We made it all the way up to 3700 MHz! That is without changing timings or voltage, pretty impressive! This was a 100% stable overclock too, we could easily run our kit at 3600 MHz all the time.
That extra 500 MHz was a nice boost, here is how that overclock compares to other DDR4 modules we’ve tested recently.
