128GB DDR4 ECC RDIMM kit

This 128GB kit contains two 64GB DDR4 3200 registered ECC modules built for ASRock Rack ROMED8-2T EPYC motherboards. The 2Rx4 organisation and CL22 latency suit multi-socket server workloads that require error correction and registered signalling.

Registered DDR4 for EPYC platforms

The modules operate at 1.2V and conform to the PC4-25600 standard with 288-pin RDIMM form factor. Registered buffering reduces electrical load on the memory controller, freeing motherboard slots for additional capacity while maintaining signal integrity across populated channels.

Suited for ASRock EPYC server upgrades

Buyers expanding an ASRock Rack ROMED8-2T system with validated ECC RDIMMs will find this kit a direct fit. Builders needing unbuffered UDIMMs, non-ECC memory, or different speeds and capacities should look elsewhere.

Highlights

  • 128 GB total capacity from two 64 GB modules
  • DDR4 3200 speed for high-throughput server workloads
  • ECC registered design protects data integrity
  • 20 V operation reduces power draw
  • Validated for ASRock Rack ROMED8-2T EPYC motherboard
