ASRock ROMED8-2T DDR4 2933 ECC RDIMM

This 16 GB DDR4 2933 registered ECC module is validated for the ASRock Rack ROMED8-2T motherboard running AMD EPYC processors. It delivers 16 GB of capacity in a single 288-pin RDIMM with CL21 latency and 1.20 V operation. The 2Rx8 organisation suits multi-channel server configurations.

16 GB single-module server upgrade

The package contains one 16 GB stick, so each slot filled adds 16 GB of registered ECC memory without mixing ranks. No heat spreader is fitted, keeping the profile low for dense chassis. The module uses major OEM chips from Samsung, Micron or Hynix and carries part number MR23400-628K1.

16 GB per slot headroom for EPYC workloads

Each installed module provides 16 GB of error-correcting capacity, scaling linearly with every populated DIMM slot on the ROMED8-2T. Registered buffering and ECC maintain data integrity under sustained server loads. Systems needing more than the available slots can hold will require higher-density modules.

Questions about this item

Will the 2Rx8 DDR4 chips need replacement during the server's lifetime?

ECC RDIMM modules like this 16 GB DDR4 2933 stick are solid-state with no moving parts, so they do not wear out under normal operation and rarely require replacement.

What limits sustained throughput on the 288-pin RDIMM at 2933 MT/s?

The CL21 CAS latency and 1.2 V JEDEC voltage set the timing and electrical ceiling for continuous data transfer on this registered module.

How much heat does the 1.2 V registered DIMM produce when running all day?

Operating at 1.2 V without a heat spreader, the 2Rx8 DDR4 RDIMM generates modest heat that standard server airflow handles without extra cooling.
