SK hynix DDR5-8000: The World's Fastest DDR5 MCR DIMM Server Memory

SK hynix announced the creation of the fastest DDR5 server memory modules - they have a speed of 8000 MT / s (or 8 Gb / s). That's about 80% faster than the standard DDR5-4800 modules used in the server segment. At the same time, the manufacturer did not overclock the memory itself, but still made the modules almost twice as fast.

A key feature of the SK hynix DDR5-8000 server memory is the Combined Ranks Multiplexer (MCR) technology developed in collaboration with Intel and Renesas. With the help of a special chip developed by Renesas that acts as a data buffer, the SK hynix provided the ability to simultaneously use two memory rows (chips on both sides of the module) to increase the data channel width to 128 bits instead of the normal 64 bits. The Renesas chip acts as an intermediate link between the central processor and the RAM module.

The new memory architecture offers the ability to simultaneously send twice as much information to the CPU compared to conventional DRAM modules. As a result, a significant increase in module speed is achieved without the need to increase the frequency of the memory chips themselves.

Sameer Kuppahalli, vice president and general manager of Renesas' memory interfaces division, said the development of the data buffer took three years of intensive work. Intel, for its part, notes that it is looking forward to the use of MCR technology by future Xeon platforms. SK hynix expects the new memory to be sought after in the HPC segment, but has yet to announce the start date for mass production of the MCR DIMM memory.
