ECC RDIMM kit for EPYC servers

This NEMIX RAM kit provides 16 GB of DDR4 3200 registered ECC memory in a matched pair of 8 GB modules. It targets administrators who need validated stability on ASRock Rack ROMED8-2T motherboards running AMD EPYC processors. The modules operate at 1.2 V with CL22 latency and use major OEM DRAM from Samsung, Micron or Hynix.

Upgrade from non-ECC or slower RDIMMs

Replacing unbuffered consumer DIMMs or lower-speed registered modules eliminates data-corruption risk and matches the platform’s qualified memory list. The jump is worth it when workloads demand error correction and the motherboard requires registered DIMMs to populate all slots at rated speed.

Fits ASRock Rack ROMED8-2T DDR4 slots

Each 288-pin RDIMM installs directly into the server board’s memory channels without heat spreaders that could interfere with tight heatsink clearance. The 1Rx8 organisation leaves additional ranks available per channel for future capacity expansion while keeping the memory controller within its supported load limits.

Questions about this item

Will these 288-pin DDR4 RDIMMs fit the DIMM slots on my ASRock Rack ROMED8-2T motherboard?

Yes, the 288-pin RDIMM form factor matches the DDR4 slots on the ASRock Rack ROMED8-2T, and the kit is validated for that board.

Do I need to populate specific slots or follow a channel order when installing this 2x8GB kit?

Install one module per memory channel, typically using the same-coloured slots first; consult the ROMED8-2T manual for the exact population sequence.

Are the Samsung, Micron or Hynix ICs on these modules user-serviceable or replaceable later?

No, the DRAM chips are soldered to the PCB; if a module fails you replace the entire DIMM rather than individual components.
