NEMIX RAM 8GB DDR4 2666MHz ECC RDIMM

This 8GB registered DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It uses a 1Rx8 organisation and 288-pin form factor for server motherboards. ECC and registered buffering provide the data-integrity required in multi-socket environments.

Suited for ASRock Rack EPYC servers needing

Ideal for administrators upgrading compatible ASRock Rack ROMED8-2T platforms where registered ECC RDIMMs are mandatory. Not suitable for builds that require unbuffered UDIMMs, non-ECC memory, or higher-density modules beyond the single 8GB stick supplied.

Registered ECC RDIMM with 1Rx8 organisation

The registered buffer and ECC capability decide whether this module works in a given server; consumer boards without registered support will not post with it. Verify the motherboard qualified-vendor list for 1Rx8 2666MHz RDIMMs before purchase.

Questions about this item

Does this 288-Pin DDR4 RDIMM require a motherboard that supports registered ECC memory?

Yes, the module is a registered ECC RDIMM and must be installed in a motherboard that accepts DDR4 2666 registered ECC memory.

Can I mix this CL19 1Rx8 module with existing DDR4 2666 ECC RDIMMs of a different rank or latency?

Mixing ranks or CAS latencies is possible but the system will run all modules at the slowest common timing; check your motherboard manual for supported rank configurations.

After installation, how can I verify the module is running at 2666 MHz with ECC active?

Enter the BIOS or use a hardware information tool to confirm the memory speed reads 2666 MHz and that ECC status shows enabled or active.
