Two green DDR4 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 16GB (2x8GB) DDR4 2666 ECC RDIMM CL19 1.2V 288-Pin Kit for ASRock Rack ROMED8-2T EPYC memory upgrade

SKU CH-4NQY-DQJEM

DDR4 2666 ECC registered 16 GB kit (2 × 8 GB) validated for ASRock Rack ROMED8-2T EPYC motherboards

  • Capacity16GB (2 x 8GB)
  • SpeedDDR4 2666 (PC4 21300)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V

Capacity 16GB 2X8GB

  • 16GB kit adds capacity for multi-threaded workloads
  • ECC registered design protects data integrity in servers
  • DDR4 2666 speed matches platform specification
  • 2V operation reduces power draw under load
  • Validated for ASRock Rack ROMED8-2T EPYC motherboard

Server Memory Kit

This 16GB DDR4 kit contains two 8GB registered DIMMs built for the ASRock Rack ROMED8-2T motherboard supporting AMD EPYC processors. It targets administrators upgrading or repairing that specific server platform with validated ECC memory.

Registered ECC at 2666 MT/s

The modules run at DDR4 2666 (PC4-21300) with CL19 latency and 1.2V operation. Registered buffering and on-die ECC provide the error correction and signal integrity required by the ROMED8-2T memory controller.

Two-Slot Population

The 288-pin RDIMMs occupy two DIMM slots on the board and use major OEM DRAM from Samsung, Micron or Hynix. No heat spreader is fitted, so airflow in the server chassis must handle module cooling directly.

Questions about this item

What does the 2666 MT/s speed mean once the modules are installed in an ASRock Rack ROMED8-2T?

The kit runs at DDR4 2666 (PC4-21300) on the EPYC platform, delivering the rated throughput as long as the motherboard memory controller is set to that speed.

How does the registered ECC design affect the usable bandwidth on this platform?

Registered modules add one clock cycle of buffering, which the EPYC memory controller accounts for; ECC provides single-bit error correction without reducing the 2666 MT/s data rate.

Will the 288-pin RDIMM sticks fit the DIMM slots on the ROMED8-2T without a heat spreader?

Yes, the 288-pin DDR4 RDIMM form factor matches the board's slots exactly, and the low-profile design without a heat spreader clears standard server CPU coolers.
