Description
V-Color 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
