256GB DDR4 ECC LRDIMM kit

This NEMIX RAM kit provides 256GB of DDR4 2666 memory in four 64GB modules. It uses Load Reduced ECC LRDIMM technology with CL19 latency and 1.2V operation. The 288-pin modules are validated for Dell EMC PowerEdge R7425 servers and built with major OEM DRAM chips.

Suited for Dell R7425 capacity upgrades

The kit targets administrators expanding memory in compatible Dell PowerEdge R7425 servers where ECC and load-reduced signalling are required. It is not for consumer desktops, workstations needing standard RDIMM or UDIMM modules, or systems that cannot accept 4Rx4 LRDIMM population rules.

Four-slot kit for matched population

The four-module package fills a matched channel set, simplifying installation without mixing ranks or speeds. It requires a platform supporting DDR4 LRDIMM at 2666 MT/s and 4Rx4 organisation. The kit frees procurement from sourcing individual validated modules and ensures uniform 1.2V operation across all slots.

Questions sur cet article

Does the Dell EMC PowerEdge R7425 need a specific BIOS revision before installing four 64 GB 2666 MT/s LRDIMMs?

The modules run at 1.2 V with CL19 timing; the server’s firmware must recognise 4Rx4 LRDIMMs at 2666 MT/s for the 256 GB kit to initialise correctly.

Will these 288‑pin LRDIMMs work in the same R7425 slots that currently hold standard RDIMMs?

Load‑reduced and registered DIMMs cannot be mixed in the same channel; all slots in a channel must use the same 4Rx4 LRDIMM type for the kit to operate.

How can I confirm the 256 GB kit is running at the rated 2666 MT/s with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode — they should report 2666 MT/s, 4Rx4 organisation, ECC enabled and a total of 256 GB across the four modules.
