256GB DDR4 ECC RDIMM Kit

This NEMIX RAM kit provides 256GB of DDR4 3200 registered ECC memory in four 64GB modules. It is built for servers and workstations that require error correction and registered signal integrity. The modules run at 1.2V with a CAS latency of 22. They are validated for the ASRock Rack ROMED8-2T motherboard with AMD EPYC processors.

Server and Workstation Upgrades

IT professionals upgrading compatible ASRock Rack platforms will find this kit matches the required specifications. Systems that need unbuffered UDIMM memory or non-ECC modules cannot use these registered DIMMs. Builders targeting consumer desktop boards or laptops should look at different memory types.

Four-Module 256GB Capacity

The 4x64GB configuration fills four DIMM slots and delivers 256GB total capacity for memory-intensive workloads. Workloads that exceed this amount will require additional slots or higher-density modules not included in this kit. The 3200MT/s speed and CL22 timing provide standard registered performance for supported platforms.

Questions about this item

What motherboard must I already have for this 256GB DDR4 3200 ECC RDIMM kit to work?

The kit is validated for the ASRock Rack ROMED8-2T motherboard with AMD EPYC processors.

Can I mix these 64GB 2Rx4 registered modules with older unbuffered DDR4 DIMMs I already own?

No, registered ECC RDIMMs cannot be mixed with unbuffered UDIMMs; the motherboard requires all slots to use registered modules.

How do I confirm the 3200 MT/s speed and CL22 latency are active after installing the four modules?

Check the BIOS memory information screen or run a tool such as dmidecode to verify DDR4-3200 operation at 1.20 V with CL22 timings.
