256GB DDR4-2933 LRDIMM kit

This NEMIX RAM kit provides 256GB across four 64GB DDR4 LRDIMM modules rated at 2933MT/s with CL21 latency. The load-reduced design and ECC support target enterprise servers and workstations that require high capacity and data integrity. Modules operate at 1.2V and use a 288-pin form factor. The kit is validated for the ASRock Rack EPYCD8-2T motherboard.

Suits EPYCD8-2T memory expansion

System builders populating the ASRock Rack EPYCD8-2T with maximum registered ECC capacity will find the correct speed, voltage and rank configuration in this kit. Environments that need unbuffered UDIMMs, non-ECC modules or speeds other than DDR4-2933 should select a different product. The 4Rx4 organisation also requires a platform that supports load-reduced DIMMs.

4Rx4 load-reduced organisation

Each 64GB module presents a 4Rx4 rank structure that reduces electrical load on the memory controller, allowing the platform to run four DIMMs per channel at the rated 2933MT/s. If the target server only accepts single-rank or dual-rank registered DIMMs, this kit will not be compatible.

Questions about this item

How can I confirm the 256GB kit is running at 2933MHz with CL21 after installation?

Check the memory speed and CAS latency in the BIOS or UEFI firmware screen; they should show 2933MHz and CL21 for each 64GB module.

What comes in the package and what must be purchased separately?

The box contains the four 64GB DDR4 2933 ECC LRDIMM modules; no cables, tools or additional hardware are included.

Which version should I choose for the ASRock Rack EPYCD8-2T motherboard?

Select the 256GB kit with part number ML23400-944K4, rated DDR4 2933 PC4-23400 CL21 1.2V 4Rx4 288-pin ECC LRDIMM.
