The rather long lifespan of DDR4 memory has allowed manufacturers to learn how to build modules running at speeds and voltages well above those specified by JEDEC’s standard. Nowadays, leading makers of modules offer DDR4 memory rated for interface data rates of up to 4600+ MT/s. At Computex, GeIL demonstrated its Super Luce modules rated for 5000 MT/s, but will such modules hit the market? Samsung’s legendary B-die chips enabled many professional overclockers to set records by hitting ultimate speeds. But while high-quality modules with cherry-picked chips are required to set records, they are not the only things that are needed for ultra-high speeds. Far not all CPUs and memory controllers can work in DDR4-5000 mode, GeIL says. In fact, only about 2% of processors...
