Memory reliability, performance and quality are more important than ever as customers 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 so you can verify that your system has TruDDR4 Memory installed. Thanks to memory authentication, memory stretch targets are only activated when TruDDR4 Memory DIMMs are detected.
