Server Memory Upgrade

This 128GB DDR4 3200 ECC RDIMM module targets server and workstation administrators who need maximum registered memory capacity in a single DIMM slot for virtualisation, database or compute-intensive workloads.

Build Integration

The registered 4Rx4 design requires a platform that supports load-reduced or quad-rank registered DIMMs and a 288-pin DDR4 slot; it frees additional slots for further expansion while delivering 128GB from one module.

Thermals and Power

Operating at the standard 1.2V DDR4 voltage with CL22 latency, the module draws minimal power and generates low heat under typical server loads, contributing to quiet, stable operation in densely populated chassis.

Points forts

  • 128 GB capacity handles heavy server workloads
  • DDR4 3200 speed moves data at 25600 MT/s
  • ECC registered design protects data integrity
  • 4Rx4 rank layout maximises module density
  • CL22 latency at 1.20 V balances performance and power

Questions sur cet article

How does the CL22 latency affect sustained throughput on this DDR4 3200 module?

CL22 is the rated CAS latency at 3200 MT/s; lower latency would improve response time but the module is validated at this timing.

What thermal output should I expect when the 128 GB RDIMM runs continuously at 1.20 V?

The module operates at standard DDR4 1.20 V with no additional cooling requirement beyond normal server airflow.

Does my motherboard need 288-pin DDR4 slots that support 4Rx4 registered ECC DIMMs?

Yes — this is a 288-pin DDR4 RDIMM with 4Rx4 organisation and ECC; the board must accept registered ECC memory in that configuration.
