32GB DDR4 2666 ECC RDIMM

This 32GB DDR4 2666 ECC RDIMM module delivers 32GB of registered memory for ASRock Rack EPYCD8-2T series motherboards. It operates at 2666MHz with a CAS latency of 19 and a voltage of 1.2V. The 2Rx4 rank configuration supports error-correcting code for data integrity in server environments.

Thermals and power

The module runs at 1.20V standard DDR4 voltage without a heat spreader attached. Registered buffering reduces electrical load on the memory controller during sustained workloads. Power draw scales with the 2666MHz operating frequency under typical server utilisation.

What the package includes

The package contains a single 288-pin DDR4 RDIMM module rated at PC4-21300. Major OEM chips from Samsung Micron or Hynix are used depending on production batch. No additional accessories cables or software utilities are bundled with the memory stick.

Questions about this item

How do I install this 288-pin DDR4 RDIMM in my ASRock Rack EPYCD8-2T motherboard?

Power down the server, open the chassis, align the module's notch with the slot key, press firmly until both latches click, then verify 32GB appears in BIOS.

What maintenance or replacement will this ECC RDIMM need over its service life?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and the module is covered by a lifetime replacement warranty if a fault ever develops.

What limit appears first when this CL19 2666MHz module runs sustained workloads?

The CL19 latency at 1.20V sets the timing boundary; sustained throughput caps at the PC4-21300 data rate before thermal throttling becomes a factor.
