256GB DDR4 ECC RDIMM kit for ASRock Rack servers

This 256GB memory kit contains eight 32GB DDR4 2400 CL17 registered DIMMs built for the ASRock Rack EPYCD8-2T motherboard. ECC and registered operation protect data integrity in multi-socket server workloads. The kit targets administrators who need maximum capacity per channel without mixing modules.

Major-brand DRAM on 288-pin registered modules

Samsung, Micron or Hynix chips run at 1.20V across all eight sticks. The 2Rx4 organisation and registered buffer reduce electrical load on the memory controller, allowing full population of every slot. No heat spreaders are fitted, so airflow in dense 1U or 2U chassis is unrestricted.

Eight matched modules shipped as a single kit

The pre-validated 8x32GB set eliminates the trial-and-error of sourcing identical rank and latency combinations separately. Each module is stress-tested under load before dispatch, reducing the chance of post-install instability. Buyers who need fewer than eight modules or a different speed grade cannot use this kit.

Questions about this item

Does the DDR4 2400 PC4-19200 interface limit the ASRock Rack EPYCD8-2T to 2400 MT/s even though the board supports 2666 MT/s?

Yes, these modules run at 2400 MT/s (PC4-19200) so the memory bus will operate at 2400 MT/s rather than the motherboard's maximum 2666 MT/s.

What physical slot and module dimensions are required to install this 288-pin RDIMM kit?

The kit uses standard 288-pin DDR4 RDIMM modules; each stick fits a regular DDR4 DIMM slot and the kit contains eight 32 GB modules.

What is the correct installation sequence for the eight 2Rx4 registered modules on the EPYCD8-2T?

Populate the DIMM slots in the order specified by the ASRock Rack EPYCD8-2T manual, typically filling one DIMM per channel per processor first, then adding the second rank; skipping the prescribed sequence is the most common mistake.
