The LENOVO ThinkSystem 16GB TruDDR4 3200MHz ECC UDIMM (Part Number: 4X77A77495) is a high-performance, server-class memory module engineered specifically for Lenovo ThinkSystem servers. This DDR4 SDRAM module offers a capacity of 16GB and operates at a fast 3200 MHz (DDR4-3200) data rate, ensuring optimal data throughput for demanding server workloads.

Designed with reliability in mind, the module supports ECC (Error-Correcting Code) technology, which detects and corrects data corruption to maintain system stability and data integrity in mission-critical environments. Featuring a dual-rank (2Rx8) design with x8 DRAM devices, this UDIMM operates at a low 1.2V voltage, and utilizes the standard 288-pin DDR4 DIMM form factor suitable for compatible Lenovo ThinkSystem servers.

The memory module is unbuffered (UDIMM) and validated under Lenovo's ServerProven program, guaranteeing seamless compatibility and performance with supported ThinkSystem platforms such as the ST50 V2, ST250 V2, and SR250 V2 servers. As a TruDDR4 family member, it's tested for reliability and performance consistency, making it ideal for data centers, virtualization, and enterprise environments requiring dependable and scalable memory solutions.
