ThinkSystem TruDDR4 Memory Experience trusted, tested, quality, performance, and reliability with ThinkSystem TruDDR4 Memory. Our memory is sourced from Tier 1 DRAM suppliers and undergoes strict selection and compatibility testing to ensure the highest quality. It is then tuned on every ThinkSystem server for maximum reliability. High Performance Memory Choose from high-performance and high-capacity memory options in ThinkSystem servers to meet your specific needs. Persistent Memory Transform your memory/storage hierarchy with Intel Optane DC Persistent Memory in Lenovo ThinkSystem servers. This breakthrough technology offers large capacity, high speed, affordable memory with data persistence and advanced encryption capabilities. With DDR4 compatible modules, you can process larger data sets with more user instances, increasing operational efficiency. 3DS RDIMMs For higher density server memory modules, Lenovo offers 3DS (3 Dimensional Stacked) DDR4 RDIMMs. These utilize TSV (Through Silicon Via) technology from our partnership with a leading Tier 1 DRAM supplier. The TSV 3DS stack technology enables higher density DRAM stack packages with higher operational frequency and reduced power consumption. This configuration provides performance benefits and lower power consumption, resulting in the lowest TCO for data centers. Performance+ Memory For memory-intensive workloads that require a competitive advantage, choose Lenovo's Performance+ memory. Our engineers have worked closely with leading memory suppliers to develop and tune ThinkSystem servers, exceeding the latest industry standard for memory performance. With increased bandwidth and lower latency at 2933 MHz, our Performance+ memory delivers superior performance for your critical workloads.
