The Lenovo TruDDR5 5600MHz ECC RDIMM 16GB (1Rx8), manufacturer part number 4X77A87322, is a registered DDR5 memory module engineered specifically for Lenovo ThinkSystem servers. Operating at 5600MHz with a single-rank, x8 organization, this module delivers high bandwidth and low latency memory performance suited to the demands of modern enterprise infrastructure, virtualization platforms, and data-intensive compute environments.
Built on DDR5 architecture, the module incorporates on-die ECC (ODECC) as a native DDR5 feature, supplemented by the registered buffer (RDIMM) design that improves signal integrity and enables greater memory capacity scalability across multi-DIMM configurations. The 1Rx8 topology optimizes the balance between capacity and signal quality, making it well-suited for single-socket and dual-socket ThinkSystem server deployments where memory channel population density is a key design consideration.
As a Lenovo TruDDR5 module, this DIMM is validated and qualified through Lenovo's server memory certification program, ensuring compatibility, stability, and performance consistency within supported ThinkSystem platforms. Enterprise IT teams deploying AI inference nodes, in-memory databases, cloud-native workloads, or high-density virtualization clusters benefit from the reliability assurances that come with platform-matched, ECC-protected DDR5 memory at 5600MHz speeds.
