Last week I looked at DDR4 memory scaling from 2133MHz to 3866MHz on the new Intel 6th Generation Core i7-6700K ‘Skylake’ processor. Since that article was published I’ve received a number of kind and helpful letters from the overclocking community, board makers and memory companies with ideas on how to get even better memory performance. Intel has yet to brief the media on the changes the made in the 14nm Skylake core architecture and it turns out I might have unintentionally been limiting some internal memory bandwidth by overclocking the DDR4 dual-channel memory without also overclocking the processors cache or ‘Ring Frequency’ as some people call it. Read on to see what happened to the memory performance after we overclocked the 6700K's CPU Cache clock speed!
