NEMIX RAM 128GB DDR4 2666 ECC LRDIMM kit

This NEMIX RAM kit provides 128 GB of DDR4 2666 memory in two 64 GB LRDIMM modules. It operates at 1.20 V with CL19 latency and includes on-die ECC with a 4Rx4 organisation. The load-reduced design lowers electrical loading on the server memory bus.

Suited for ASRock EPYCD8-2T server upgrades

The modules are validated for the ASRock Rack EPYCD8-2T motherboard and similar enterprise platforms that require registered ECC LRDIMMs. Builders needing standard UDIMMs, non-ECC memory, or higher-frequency DDR4 should select a different kit.

4Rx4 load-reduced organisation

Each 64 GB module uses a 4Rx4 rank structure that reduces the number of electrical loads presented to the memory controller. This allows the platform to populate more slots at the rated 2666 MT/s speed without signal degradation.

Perguntas sobre este artigo

What does the DDR4 2666 speed mean for actual throughput in a server?

DDR4 2666 runs at 2666 MT/s, giving each 64 GB module a PC4-21300 peak transfer rate; real-world bandwidth depends on the platform's memory controller and channel population.

How does the LRDIMM load-reduced design affect the memory bus?

The 4Rx4 LRDIMM buffers both data and address lines, reducing electrical load so the motherboard can populate more slots at the rated 2666 speed.

Will the 288-pin modules fit the ASRock Rack EPYCD8-2T DIMM slots?

Yes, the kit uses standard 288-pin DDR4 LRDIMM form factor and is validated for the ASRock Rack EPYCD8-2T motherboard.
