System-Specific DDR4 ECC Kit

This 32 GB kit contains four 8 GB DDR4 3200 registered DIMMs built for ASRock Rack ROMED8-2T motherboards running AMD EPYC processors. ECC and registered signalling protect data integrity in server and workstation workloads.

288-Pin Registered Modules in a Four-Stick Kit

Each module uses a 1Rx8 organisation at 1.20 V and fits standard DDR4 RDIMM slots. The quad-channel population fills four sockets simultaneously, leaving remaining slots open for future capacity expansion.

CL22 Latency Under Continuous Operation

Rated at CL22, the modules maintain timing consistency during sustained memory-bound tasks such as virtualisation, database caching and AI inference. Major-brand Samsung, Micron or Hynix ICs are stress-tested under load to verify stability.

Questions about this item

How does the CL22 latency affect throughput when the kit runs at DDR4 3200 under sustained load?

CL22 sets the minimum cycle delay for each column access; at 3200 MT/s the 22-cycle wait limits peak bandwidth during continuous server workloads.

What is the power draw and thermal output of the 1.2 V registered modules during all-day operation?

Each 8 GB 1Rx8 RDIMM operates at 1.2 V, so the four-module kit draws modest power and produces low heat without a heat spreader.

Which motherboard must already be installed for this 288-pin ECC RDIMM kit to function?

The kit is validated for the ASRock Rack ROMED8-2T motherboard supporting AMD EPYC processors.
