Introduction

DDR5 is the latest iteration of DRAM technology. It offers significant performance improvements over its predecessor, DDR4, with increased data transfer rates, higher memory densities, and lower power consumption. DDR5 DIMMs are the physical modules that contain DDR5 memory chips and are used to expand the memory capacity of a computer system. DDR5 DIMMs have larger burst lengths than DDR4, with a burst length of 16 vs. 8, which allows for a greater amount of data to be transferred between the memory and the CPU.

DDR5 DIMMs also feature improved error correction capabilities, x80 vs. x72 with DDR4, making them more reliable and less prone to data corruption. DDR5 DIMMs operate at a voltage of 1.1 volts, which is lower than the 1.2 volts required by DDR4 DIMMs. This, combined with other power-saving features, makes DDR5 DIMMs more energy-efficient than their predecessors. DDR5 RDIMM includes a Power Management Integrated Circuit (PMIC) to manage power consumption, voltage regulation, and other aspects of power delivery. This is not present in DDR4 because it is a newer technology, designed with more advanced power management features to support higher memory speeds and lower power consumption. Overall, DDR5 DRAM DIMMs represent a significant upgrade in memory technology and are expected to become the standard for high-performance computing in the years to come.

DDR5 MRDIMM (Multiplexed Rank DIMM) is specifically designed to meet the demanding needs of AI and HPC servers. By leveraging existing DDR5 DRAM memory devices, MRDIMM modules double the DRAM data rate, providing up to 2.3X better performance for HPC workloads and up to 2X better performance for AI inference workloads. This high bandwidth and low latency memory solution accelerates memory-intensive applications, making it ideal for environments that require rapid data processing and real-time analytics. Additionally, MRDIMM modules maintain the reliability and error correction capabilities of RDIMM modules, ensuring robust performance in critical computing tasks. With these advancements, DDR5 MRDIMM offers a compelling value proposition for enhancing the efficiency and speed of AI and HPC servers.

Netlist offers a wide lineup of leading-edge commercial and industrial grade DDR5 DIMMs and DDR5 MRDIMMs. All memory and storage products are 100% system tested from -40°C to +95°C for Industrial Temp Grade and from 0°C to +85°C for Commercial Temp Grade. Netlist’s rigorous testing process is specifically designed to ensure these modules will operate reliably in harsh, long-life computing environments and densely configured computing applications with limited airflow.
