128 GB DDR4 ECC RDIMM kit

This 128 GB kit contains four 32 GB DDR4 2933 registered DIMMs built for the ASRock Rack ROMED8-2T motherboard. It targets administrators who need validated ECC memory for AMD EPYC server platforms.

Thermals power and noise

The modules run at 1.20 V without heat spreaders, relying on chassis airflow for cooling. Registered buffering and ECC operation add negligible power draw and produce no audible noise under normal server loads.

ASRock ROMED8-2T compatibility

The kit is qualified for the ASRock Rack ROMED8-2T board with AMD EPYC processors; it is not suited for consumer desktops or boards that require unbuffered non-ECC memory.

Highlights

  • 128 GB total capacity across four 32 GB modules
  • DDR4 2933 MHz speed with PC4-23400 bandwidth rating
  • ECC registered RDIMM design for server data integrity
  • 2Rx4 dual-rank organisation for dense memory configurations

Questions about this item

How do I install the 288-pin DDR4 RDIMM modules in the ASRock Rack ROMED8-2T and what step is often missed?

Power off the server, open the chassis, align each module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all 128 GB are detected at 2933 MT/s with ECC enabled.

What maintenance or replacement will the 2Rx4 ECC RDIMM kit need over its service life?

The modules have no moving parts or heat spreaders; only periodic dust removal from the DIMM slots and a firmware update if the platform vendor releases new memory-training code are required.

What limit appears first when the 1.2 V CL21 registered memory runs sustained workloads on EPYC?

The memory controller’s maximum supported data rate of 2933 MT/s is the ceiling; sustained throughput cannot exceed the PC4-23400 bandwidth of the installed 4×32 GB configuration.
