256GB DDR5 ECC RDIMM kit

This NEMIX RAM kit supplies 256GB across four 64GB DDR5 modules rated at 6400MHz with CL52 latency. Registered ECC design and 1.10V operation target stability in compatible Supermicro server platforms. The 288-pin RDIMM form factor uses major OEM Samsung, Micron or Hynix chips in a 4Rx4 organisation.

Suited for Supermicro X14SBW-TF upgrades

Builders expanding memory on the named Supermicro board gain registered ECC capacity with validated compatibility. Systems requiring unbuffered DIMMs, non-ECC modules or lower-density kits should select a different product. Workloads that exceed 256GB per channel or need heat spreaders will also need an alternative.

256GB total capacity headroom

Four 64GB modules fill four slots and deliver 256GB of registered ECC memory for virtualisation, database or AI inference tasks. The kit runs out when the platform demands more than 256GB in this configuration or when thermal design requires integrated spreaders. Additional capacity requires a motherboard with more slots or higher-density modules.

Highlights

Questions about this item

Will this 256GB DDR5 ECC RDIMM kit work in my Supermicro X14SBW-TF motherboard?

Yes, the kit is validated for the Supermicro X14SBW-TF platform and ships as a matched set of four 64GB registered DIMMs.

Can I mix these 6400MHz CL52 modules with slower DDR5 RDIMMs already installed?

The motherboard will run all installed DDR5 RDIMMs at the speed and latency of the slowest module present.

How do I verify the 256GB kit is running at 6400MHz with ECC active after installation?

Check the memory speed and ECC status in the BIOS setup or use a tool such as dmidecode to confirm 6400MHz operation and error-correction enabled.
