SK hynix launches 8Gbps MCR DIMM server memory module

SK hynix announced that it has successfully developed a DDR5 Multiplexer Combined Ranks (MCR) Dual In-line Memory Module (DIMM), achieving a data transfer rate of 8 Gbps. According to SK Hynix, this is the fastest server DRAM product in the industry, which is more than 80% faster than ordinary DDR-4800.

SK hynix has adopted a brand-new method to increase the data transfer rate of DDR5. In general, the operating speed of DDR5 depends on the speed of a single DRAM chip. However, SK Hynix has taken a different approach to achieve higher speeds by increasing the speed of the entire module, not a single DRAM chip. The product is designed based on Intel MCR technology, using the data buffer installed on the MCR DIMM to run two memory ranks at the same time.

According to SK Hynix, traditional DRAM modules can only transmit 64 bytes of data to the CPU at a time, while in MCR DIMM modules, two memory ranks can transmit 128 bytes of data to the CPU at the same time. Such a design increases the amount of data transferred to the CPU each time, and the data transfer rate increases to more than 8 Gbps, twice that of a single DRAM.

SK Hynix also works closely with Intel and Renesas Electronics to integrate its own DRAM module design capabilities with the buffer technology of Intel Xeon processors and Renesas Electronics, and speed up the development to performance verification and other stages of the speed.

SK Hynix predicts that the market for MCR DIMM modules will gradually open up driven by high-performance computing’s demand for increased memory bandwidth. SK Hynix plans to mass-produce this product in the future but did not disclose the specific time.
