Types of Server RAM Form Factors We Offer

RDIMM (Registered DIMM) Server RAM

RDIMM RAM is designed for enterprise-level servers that require high memory capacity and stability. It offers better signal integrity and supports ECC (Error Correcting Code), making it ideal for critical workloads like virtualization, databases, and AI computing.

  • Popular RDIMM Capacities:
    16GB, 32GB, 64GB, 128GB, 256GB, 512GB, 1TB
  • Compatible Brands:
    Dell, HPE, Lenovo, IBM, Cisco, Supermicro

SODIMM (Small Outline DIMM) Server RAM

SODIMM RAM is a compact memory module used primarily in space-constrained devices like edge servers, microservers, and Synology NAS systems. Despite their size, they deliver excellent performance and ECC support in supported platforms.

  • Popular SODIMM Capacities:
    8GB, 16GB, 32GB, 64GB
  • Common Use Cases:
    NAS systems, mini servers, Synology, QNAP

UDIMM (Unbuffered DIMM) Server RAM

UDIMM modules are typically used in entry-level servers and workstations. These modules offer lower latency but lack the buffer or register that RDIMMs provide. They’re best suited for non-critical server tasks or small businesses.

Popular UDIMM Capacities:
8GB, 16GB, 32GB, 64GB

Best for:
HP Workstations, Dell Precision, home labs

How to Choose the Right RAM Form Factor

  • ✅ Check your motherboard/server specs
  • ✅ RDIMM is best for large, scalable servers
  • ✅ UDIMM suits small servers and workstations
  • ✅ SODIMM is used in compact or embedded systems
  • ✅ Confirm ECC support based on your CPU & chipset
