Korean chip manufacturer SK Hynix has unveiled the world’s first 64GB DDR5 RAM modules, marking a big step away from DDR4 SIMs that have dominated PC memory since 2013. The DDR5-4800 chips support speeds between 4,800 and 5,600 Mbps with faster potential data rates than DDR4, while using less power. The technology also allows for modules of up to 256GB in size.
The JEDEC standard for DDR5 RAM was officially published in July this year, but SK Hynix unveiled its first chips in 2018. Apart from the memory gains, DDR5 will have two 32-bit channels instead of a single 64-bit channel, making it easier to increase peak bandwidth. The modules themselves will also regulate voltage instead of the motherboard, allowing the DDR5 RAM manufacturer to control the all-important clock speeds. All told, it could make for some very interesting enthusiast RAM options.
