512GB DDR4 2933MHz ECC LRDIMM Kit

This NEMIX RAM kit provides 512GB of total capacity across eight 64GB modules. The memory operates at DDR4 2933MHz with a PC4-23400 rating and CL21 latency. It uses Load Reduced DIMM technology with 4Rx4 organisation and on-die ECC for data integrity. The modules run at 1.20V and fit 288-pin DDR4 slots.

Suited for ASRock Rack EPYC servers needing

This kit is built for the ASRock Rack ROMED8-2T motherboard and similar AMD EPYC platforms that support LRDIMM populations. It targets administrators who need the highest possible memory density per channel. Buyers using consumer desktop boards, workstations limited to RDIMM, or systems requiring registered DIMMs instead of load-reduced modules should look elsewhere.

Verify motherboard LRDIMM support

Before ordering, confirm your board accepts 4Rx4 LRDIMMs at the full 2933MHz speed with all eight slots filled. Check the vendor’s qualified vendor list for the exact part number ML23400-944K8. Ensure the BIOS revision supports this density and rank configuration. Cooling airflow over the bare modules must be adequate as no heat spreaders are fitted.

Soalan tentang produk ini

What motherboard must I already have for this 512 GB DDR4 2933 MHz ECC LRDIMM kit to be compatible?

This kit is validated for the ASRock Rack ROMED8-2T motherboard built around the AMD EPYC platform, so that board must be installed before the memory will work.

Will these 4Rx4 LRDIMM modules run with older DDR4 2666 MHz registered DIMMs I may keep in the same system?

The board will down-clock all modules to the lowest common speed, so the 2933 MHz LRDIMMs will operate at 2666 MHz alongside the older registered DIMMs.

How can I confirm the kit is running at the rated 2933 MHz CL21 1.20 V after installation?

Check the BIOS memory information screen or a tool such as dmidecode; it should report 2933 MT/s, CAS latency 21, 1.20 V and 4Rx4 organisation for each of the eight 64 GB modules.
