The reliability, performance, and quality of memory are more important than ever today, as customers increasingly require more memory for big data and analytics, cloud computing, virtualization, databases, and high-performance computing (HPC). 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 that allows you to verify whether TruDDR4 Memory is installed in your system. Thanks to memory authentication, memory stretch goals are activated only when TruDDR4 Memory DIMMs are detected.
