Targeted Server Upgrade

This NEMIX RAM module is a 64 GB DDR5 Registered ECC RDIMM built to the exact electrical and mechanical specification of the Supermicro X14SRA-F motherboard. It arrives as a single 288-pin DIMM rated for 6400 MT/s at CL52 with a 1.1 V operating voltage. System integrators and IT teams use it to expand memory capacity on qualified platforms without compatibility guesswork.

Fitment And Use Case

The part suits administrators who have confirmed the X14SRA-F supports 4Rx4 Registered DIMMs at this density and speed, and who need ECC error correction for production workloads. It is not for desktop PCs, workstations that require unbuffered UDIMMs, laptops needing SODIMMs, or any board that cannot accept Registered memory or the 4Rx4 rank configuration. Always verify the motherboard manual for approved population rules before ordering.

Critical Spec Decider

The 4Rx4 Registered ECC organisation at 1.1 V and CL52 is the single specification that determines whether this module will be recognised and run at its rated 6400 MT/s on the target server. If the platform memory controller expects a different rank geometry, voltage, or latency, the DIMM will not operate as intended. Match these parameters exactly to the system documentation.

Questions about this item

What slot type and pin count does this 288-pin DDR5 RDIMM require on the Supermicro X14SRA-F?

It fits a standard DDR5 RDIMM slot with 288 pins; the board must accept registered ECC modules, not UDIMM or SODIMM form factors.

Which DIMM population order does the X14SRA-F manual specify for a 4Rx4 64GB module?

Install the module in the slot sequence listed in the motherboard manual for registered ECC DIMMs; populated slots must follow the board's approved order to train at DDR5 6400.

When should the ECC error counters on this 1.1V CL52 kit be reviewed for possible replacement?

Monitor the system's corrected-error logs; if single-bit corrections rise sharply or uncorrectable errors appear, schedule module replacement to avoid silent data corruption.
