Show 4 more configurations
  • 256 GB capacity lets you fully populate the Supermicro X14SRG-TF with four 64 GB modules
  • DDR5 6400 speed matches the board's rated frequency so the controller runs at full data rate
  • CL52 latency and 1.1 V voltage meet the exact timing and power profile the platform expects
  • Registered ECC architecture buffers each command and corrects single-bit errors to prevent silent data corruption
  • 288-pin RDIMM form factor fits the server's DIMM slots and supports the required 4Rx4 rank configuration

Exact-match DDR5 RDIMM kit for Supermicro X14SRG-TF

This 256 GB kit contains four 64 GB DDR5 6400 modules built to the precise rank, voltage and timing the board expects. Registered ECC RDIMM architecture ensures the memory controller recognises full capacity at rated speed. It is not suited for workstations that require unbuffered UDIMMs or SODIMM form factors.

Thermals and power at rated operation

Each module runs at 1.1 V with CL52 latency, keeping power draw low across all four populated slots. The registered design buffers address and command signals, reducing electrical load on the controller during sustained workloads. No heat spreader is fitted, so chassis airflow must be adequate for dense server configurations.

Build quality and daily implications

Major OEM Samsung, Micron or Hynix chips provide enterprise-grade stability with on-the-fly single-bit error correction. The 288-pin RDIMM form factor matches the motherboard's slot requirements exactly, avoiding fitment issues. Population order and maximum supported capacity should be confirmed in the system manual before installation.

Questions about this item

How do I install the four 64GB DDR5 RDIMM modules in the Supermicro X14SRG-TF, and which slot order does the manual require?

Power down the server, open the chassis, and insert each 288-pin RDIMM into the exact DIMM sequence shown in the Supermicro X14SRG-TF manual; the registered 4Rx4 modules must occupy the approved slots in the prescribed order so the memory controller recognises the full 256GB at DDR5-6400 CL52 1.1V.

What maintenance or replacement will the NEMIX RAM DDR5 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so routine maintenance is limited to keeping server airflow clean; if a 64GB RDIMM ever fails, the lifetime replacement warranty covers a direct swap of the defective stick.

What is the first limit that appears when the 256GB kit runs sustained workloads on the X14SRG-TF?

The registered 4Rx4 architecture offloads the memory controller, allowing all four slots to stay fully populated at the rated DDR5-6400 CL52 1.10V without down-clocking, so the practical ceiling is the motherboard's maximum supported capacity rather than a thermal or signal-integrity bottleneck.
