Lenovo TruDDR4 DIMM 288-pin 3200 MHz Unbuffered 16GB DDR4 Memory Module

The Lenovo 4X77A77495 is a TruDDR4 memory module built to give a compatible server a reliable 16 GB performance boost. Operating at 3200 MHz, it feeds the processor with data quickly, so applications start faster and multitasking feels smooth.

Because the module includes error correcting code, it can detect and repair common memory errors as they occur. This protective feature makes it a sensible choice for file servers, virtualization hosts, and other workloads where stability is critical. Its unbuffered design fits naturally in single-socket tower systems such as the ThinkSystem ST250 V2 and slim rack models like the SR250 V2, and it is equally at home in any motherboard that accepts standard 288-pin DIMMs.

Installation takes only a few minutes: power down the system, open the chassis, press the module into an open slot, and power back on. The additional capacity lets you spin up more virtual machines, keep larger databases in memory, or support more simultaneous users without slowdowns.

The 1.2 volt operating level draws less power than earlier memory generations, which helps reduce heat and overall energy costs. Every TruDDR4 module passes Lenovo's rigorous validation tests, so you can deploy it with confidence in around-the-clock environments.
