881901-B21 HPE 64GB 2666mhz DDR4 SDRAM Pc4 21300 Ecc

881901-B21 Overview This memory module uses DDR4 SDRAM (Synchronous Dynamic Random Access Memory) technology. DDR4 is the fourth generation of DDR memory technology and is an improvement over the previous DDR3 technology. DDR4 memory technology offers higher memory speeds, improved power efficiency, and increased memory capacities compared to DDR3. It uses a lower operating voltage of 1.2V compared to DDR3’s 1.5V, which reduces power consumption and heat generation. This means that DDR4 memory can run cooler and more efficiently than DDR3 memory, which can prolong the life of the memory and the system as a whole.
