Lenovo 46W0821 8GB DDR4 2400/PC4-19200 RDIMM 288-Pin CL17 Memory Module

The Lenovo 46W0821 is an 8 GB DDR4 memory module designed for servers and workstations that need a dependable capacity boost without unnecessary complexity. Running at 2400 MHz (PC4-19200) and using error-correcting code, it helps maintain data integrity by detecting and correcting common memory errors before they disrupt mission-critical tasks.

Because it follows the 288-pin registered DIMM layout and operates on only 1.2 volts, this module balances power efficiency with consistent throughput. The single-rank x4 configuration offers a straightforward way to expand memory in systems that already support registered memory, letting administrators add more workload headroom without overhauling existing hardware.

CL17 latency keeps response times under control, which is important when multiple users or applications demand resources at the same time. Whether the goal is to support a virtualized environment, run a database that needs fast access to large data sets, or give a creative workstation room to handle large media files, the 46W0821 installs quickly and starts contributing to smoother performance right away.

This module fits naturally into small business servers, branch-office appliances, and professional desktops that rely on round-the-clock stability. IT teams looking for a predictable upgrade path will appreciate that it comes from Lenovo, a brand whose components are already validated in many enterprise platforms.
