Unigen’s DDR5 Registered DIMM (RDIMM) portfolio offers enterprise grade memory modules for high-performance compute, storage, networking, AI, and industrial applications. Supporting up to 6400 MT/s speeds, Unigen’s DDR5 RDIMMs can provide up to 2x bandwidth improvement over prior generation DDR4 systems. Standard height and Very Low Profile (VLP) form factors are available. At just 18.75mm height, VLP RDIMMs allow for vertical DIMM placement in 1U blade servers and other embedded systems to save board space.

Benefits
- Next-Gen Speed and Bandwidth: Leveraging high-performance DDR5 technology, these RDIMMs support rapid speeds of up to 6400 MT/s. This allows the modules to deliver up to a 2x bandwidth improvement over legacy DDR4 systems, making them ideal for data-heavy, high-performance compute, storage, and AI applications.
- Space-Saving VLP Form Factor: Alongside standard-height modules, Unigen offers Very Low Profile (VLP) RDIMMs that stand at just 18.75mm tall. This ultra-compact design enables vertical DIMM placement within high-density 1U blade servers and embedded systems, drastically saving board space and optimizing airflow.
- Industrial-Grade Reliability and Testing: Built to withstand harsh environments, these modules support wide industrial operating temperatures ranging from -40°C to +85°C. Every single module undergoes 100% Burn-In testing across all addresses and features 30μ gold finger plating alongside IPC-610 Class 2 manufacturing to guarantee long-term enterprise reliability.
- Flexible Customization and Compliance: Meeting strict JEDEC design specifications, the portfolio uses multi-sourced, server-grade DRAM for reliable supply chains. It is fully RoHS compliant and offers premium optional configurations, including specialized anti-sulfur protection, conformal coating for moisture resistance, and an “Assembled in America” manufacturing option.
