The W403Y 64GB RDIMM is a Dual Rank X4 DDR4 Memory module that operates at speeds up to 2933MHz and has a CL21 latency. It is a 1.2 V Voltage Memory and is ECC Registered. It conforms to the industry standard DIMM layout of 288 pins, this DDR4 SDRAM is compatible with multiple Dell PowerEdge servers. Random Access Memory (RAM) is a type of hardware that your computer uses to store information. Adding memory is one of the most cost-effective ways to improve your computer's performance. With more memory, the faster that data and instructions can be read, written, and performed by the server.

 Featuring exceptional speed, high reliability, low energy consumption High-performing memory empowers faster, powerful solutions. DDR4 delivers top speed with better bandwidth and reliability using less energy. DDR4 is a memory standard designed as a better, faster, more reliable replacement for DDR3. a DDR4 module, or DIMM, has 288 pins compared with DDR3's 240 pins. The DDR4 key notch is in a different place, and the edge connector looks like a slightly curved "V" to facilitate insertion. This design also lowers insertion force, as not all pins are engaged simultaneously during module insertion. DDR4 modules are more energy-efficient, operating only at 1.2V. The reduced power consumption gives substantial power savings and allows operation at higher speeds without higher power and cooling requirements.
