We use the highest quality industry-standard memory components sourced from Tier 1 DRAM suppliers. Only memory that meets these strict requirements are selected for memory in Lenovo servers. It is then compatibility tested and tuned on every ThinkSystem server to maximize reliability.In addition, Lenovo memory DIMMs for servers have a unique signature programmed into them so your system can verify that TruDDR5 and TruDDR4 memory is installed in your system. Since the memory will be authenticated, memory stretch goals are enabled only when TruDDR4 memory DIMMs are detected. Together with lower power consumption, these new DIMMs can provide the lowest TCO for data centers.
