SK hynix Registered DDR4 SDRAM DIMMs (Registered Double Data Rate Synchronous DRAM Dual In-Line Memory Modules) are low power, high-speed operation memory modules that use DDR4 SDRAM devices. These Registered SDRAM DIMMs are intended for use as main memory when installed in systems such as servers and workstations.
Features
• 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
• Data transfer rates: PC4-2933;32GB
