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 IBM's TruDDR4 Memory Portfolio for System x servers and IBM Flex System compute nodes, you can enhance the performance of all workloads, as many applications immediately benefit from larger memory. The IBM TruDDR4 Memory Portfolio includes RDIMMs and LRDIMMs with advanced error correction for reliability, 2,133 MHz performance, and maximum memory capacity. IBM TruDDR4 Memory DIMMs feature a unique, programmed signature so you can verify that TruDDR4 Memory is installed in your system. Thanks to memory authentication, memory-stretch targets are only activated when TruDDR4 Memory DIMMs are detected.
