Server Memory Kit

This NEMIX RAM kit provides 3TB of DDR4 server memory across twelve 256GB registered DIMMs. It operates at 2933MHz with a CAS latency of 21 and runs at 1.2V. The modules use 8Rx4 organisation and include ECC for data integrity in mission-critical environments.

Suitable For Enterprise Servers

This memory is built for servers that require DDR4 2933MHz registered ECC DIMMs with 8Rx4 ranking. It is not for desktop PCs, workstations that need unbuffered modules, or systems limited to lower capacities per slot. Buyers needing non-ECC or consumer-form-factor memory should look elsewhere.

Capacity And Headroom

The 3TB total capacity across twelve slots supports large-scale virtualisation, in-memory databases and heavy compute workloads. Each 256GB module fills a single 288-pin slot, so maximum density is reached when all twelve are populated. Systems with fewer slots or lower per-slot limits cannot use the full kit.

Questions about this item

Does my server need 288-pin DDR4 RDIMM slots to accept these 256 GB modules?

Yes, each module is a 288-pin DDR4 RDIMM, so the motherboard must provide registered DIMM slots that match this pin count and form factor.

Will the 8Rx4 organization and ECC function work with my existing RDIMMs of a different rank?

The kit uses 8Rx4 registered ECC modules; mixing ranks is possible only if the platform's memory controller and BIOS support the combined rank population.

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

Check the BIOS memory information or a tool such as dmidecode to verify the reported speed of 2933 MT/s and CAS latency of 21 for each installed module.
