ASRock ROMED8-2T EPYC DDR4 2666 ECC RDIMM Kit

This 32 GB kit contains two 16 GB registered DDR4 modules rated at 2666 MT/s with CL19 latency. ECC and registered buffering protect data integrity in multi-socket EPYC server platforms. The 1.2 V modules use 2Rx8 organisation and fit 288-pin RDIMM slots on the ASRock Rack ROMED8-2T motherboard.

Upgrading from non-ECC or slower DDR4 on ROMED8-2T

Replacing unbuffered or lower-speed memory with this registered ECC kit enables the platform’s full RAS capabilities and matched 2666 MT/s throughput. The jump is worth it when workloads demand error correction, higher capacity per DIMM slot, or validated compatibility with the ASRock Rack EPYC board.

Dual-rank 2Rx8 RDIMMs for dense EPYC server builds

Each module presents two ranks to the memory controller, allowing higher total capacity within the board’s eight-channel architecture. No heat spreaders are fitted, so airflow must be managed by the chassis. The kit frees remaining DIMM slots for further expansion up to the platform limit.

Questions about this item

Does the 288-pin DDR4 RDIMM fit the ASRock ROMED8-2T EPYC board?

Yes, the kit is built for that motherboard; each 16 GB module uses the standard 288-pin DDR4 RDIMM form factor the board expects.

What BIOS setting is commonly missed when installing these registered ECC modules?

After seating both 2Rx8 sticks, enable ECC in the BIOS so the server can use the error-correction the modules provide.

Will the Samsung, Micron or Hynix chips on these sticks need replacement under normal server loads?

The modules are stress-tested before shipping and carry a lifetime replacement guarantee, so no routine chip replacement is expected.
