SK hynix Load Reduced DDR4 SDRAM DIMMs are low power, high-speed operation memory modules that use DDR4 SDRAM devices. These Load Reduced DIMMs are intended for use as main memory when installed in systems such as servers and workstations.


  • 288 pin Load Reduced DDR4 DRAM Dual In-LIne Memory Modules
  • Buffer performance by LRDIMM presenting less load to system
  • Compatible with RDIMM systems with appropriate BIOS change
  • Power Supply: VDD=1.2V (1.14V to 1.26V)
  • VDDQ = 1.2V (1.14V to 1.26V)
  • VPP - 2.5V (2.375V to 2.75V)
  • VDDSPD=2.25V to 2.75V
  • Functionality and operations comply with the DDR4 SDRAM datasheet
  • 16 internal banks
  • Bank Grouping is applied, and CAS to CAS latency (tCCD_L, tCCD_S) for the banks in the same or different bank group accesses are available
