The Z370-LIGHTSABER motherboard from ECS is an improvement in terms of functionality and overclocking versus the previous generations; we have been able to overclock our 8600K i5 to about 4.8GHz by setting a VCore of 1.35V inside the UEFI interface, but because of the missing VDroop compensation levels, the voltage did drop quite a bit to about 1.243V at maximum load. With our G.SKILL TridentZ 32GB 3200MHz DDR4 kit, we were unable to run the pre-programmed XMP profile, so we needed to downclock a bit to about 3100MHz in order to get a fully stable, bootable system.
