Server Memory Kit

This NEMIX RAM kit delivers 512GB of DDR5 ECC RDIMM capacity across eight 64GB modules. It is built for Supermicro X14SBW-F systems that require registered, error-correcting memory for stable operation under sustained workloads. The modules run at 6400MHz with CL52 latency at 1.1V.

Registered DDR5 Modules

Each 288-pin RDIMM uses a 4Rx4 organisation with major OEM chips from Samsung, Micron or Hynix. Registered buffering reduces electrical load on the memory controller, freeing the platform to populate all slots without signal degradation. The 1.1V operating voltage aligns with standard DDR5 server specifications.

High-Capacity Server Builds

This kit suits administrators scaling a single Supermicro X14SBW-F to 512GB for virtualisation, databases or AI inference. It is not for consumer desktops, laptops or workstations that accept only unbuffered UDIMMs. Builders needing lower capacities or non-ECC memory should select a different kit.

Questions about this item

Will the 4Rx4 rank configuration hit the motherboard's maximum rank-per-channel limit before I fill all eight slots?

Each module is a 4Rx4 registered DIMM; the Supermicro X14SBW-F memory population rules determine how many ranks each channel can accept, so check the board manual before installing all eight sticks.

What power draw and heat should I expect from eight 1.1 V DDR5 RDIMMs running continuously?

The kit operates at 1.10 V per module; total power scales with eight sticks, but registered DDR5 runs cooler than unbuffered equivalents and the modules have no heat spreaders, so airflow across the DIMM slots is the main cooling requirement.

Does the Supermicro X14SBW-F need a specific BIOS revision or CPU stepping to recognise 512 GB of registered ECC memory?

Compatibility is validated for the X14SBW-F platform; the motherboard's qualified-vendor list and BIOS release notes confirm support for 64 GB 4Rx4 RDIMMs at DDR5-6400 CL52.
