The reliability, performance, and quality of memory are more important than ever today, as customers require increasing amounts of memory for big data and analytics, cloud computing, virtualization, databases, and high-performance computing (HPC). With TruDDR4 Memory for System x servers, you can enhance the performance of all workloads, as many applications immediately benefit from larger memory capacities. TruDDR4 Memory DIMMs feature a unique, programmed signature that allows you to verify whether TruDDR4 Memory is installed in your system. Thanks to memory authentication, memory stretch goals are only activated when TruDDR4 Memory DIMMs are detected.
