System-specific DDR4 ECC kit

This NEMIX RAM kit delivers 64GB across eight 8GB DDR4 3200 registered DIMMs built for the ASRock Rack ROMED8-2T motherboard. Each module runs at 1.2V with CL22 latency and 1Rx8 organisation. ECC and registered buffering protect data integrity in server and workstation workloads.

288-pin RDIMM build and daily use

Modules use major OEM Samsung, Micron or Hynix chips without heat spreaders, keeping height low for dense server chassis. The 288-pin RDIMM form factor seats directly in the board's DDR4 slots; registered signalling reduces electrical load on the memory controller. EPYC platforms benefit from the registered design when all channels are populated.

Verify platform and population rules

Confirm the ASRock Rack ROMED8-2T supports 1Rx8 registered DIMMs at 3200 MT/s and that your BIOS revision enables the full 64GB capacity. Check the motherboard manual for approved population order across the eight channels. Buyers who need non-ECC unbuffered memory or a different pin count cannot use this kit.

Questions about this item

What speed does DDR4 3200 PC4-25600 actually run at on the ASRock Rack ROMED8-2T?

The kit is rated for DDR4 3200 (PC4-25600). The EPYC platform and motherboard BIOS determine the final operating speed; it will not exceed 3200 MT/s.

Does the 288-pin RDIMM form factor with 1Rx8 organisation fit the ROMED8-2T DIMM slots?

Yes. Each module is a standard 288-pin DDR4 RDIMM, 1Rx8, matching the ROMED8-2T registered DIMM slots. The kit supplies eight modules to populate the board's eight channels.

What is the correct order to populate the eight slots on the ROMED8-2T for this 8-module kit?

Follow the motherboard manual's channel population sequence — typically one DIMM per channel, starting with the slot furthest from each CPU socket — to ensure all eight 8 GB modules are recognised at 3200 MT/s.
