Capacity 64GB

Rank 2Rx8

  • ECC protection prevents data corruption in critical workloads
  • 64GB capacity supports large virtualisation and database tasks
  • DDR4 3200 speed delivers high bandwidth for server applications
  • Registered design reduces electrical load for stable multi-module configs
  • 20V operation lowers power draw in dense deployments

64GB DDR4 3200 ECC Registered Server Memory

This Supermicro module provides 64GB of DDR4 3200 memory in a 288-pin RDIMM form factor. It operates at 1.20V with CL22 latency and includes ECC error correction plus registered buffering. The dual-rank 2Rx8 design suits high-density server configurations requiring data integrity.

Compatibility limited to listed Supermicro

The module is validated for specific UP servers including SSG-520P and SSG-540P series, and DP servers including SSG-620P and SSG-640P series. Builders using other server platforms or consumer motherboards should verify qualification before purchase. Workstations needing unbuffered UDIMMs or non-ECC memory cannot use this registered ECC RDIMM.

DDR4 3200 RDIMM with ECC and registered buffering

The combination of DDR4 3200 speed, ECC error correction and registered signal buffering defines this module's role. Systems requiring registered ECC DDR4 RDIMMs at this speed and capacity will match the specification. Servers needing different speeds, unbuffered memory or non-ECC modules must select an alternative part.
