  • 128 GB capacity lets the Supermicro H14DSG-O-CPU run fully populated at rated speed
  • DDR5-5600 (PC5-44800) CL46 timing matches the board's memory controller expectations exactly
  • Registered ECC RDIMM architecture offloads the controller and corrects single-bit errors on the fly
  • 1 V operation at 2Rx4 rank keeps power draw within the platform's design limits
  • 288-pin DDR5 RDIMM form factor fits the required Supermicro server slots precisely

Purpose-built server upgrade

This NEMIX RAM module delivers 128GB of DDR5 5600 registered ECC memory in a 288-pin RDIMM form factor. It operates at 1.1V with CL46 latency and a 2Rx4 rank structure, matching the exact electrical and timing requirements of the target platform. The kit is validated for the Supermicro H14DSG-O-CPU motherboard.

Suited for single-slot capacity needs

System administrators expanding a Supermicro H14DSG-O-CPU server with a single high-density DIMM will find this module fits the board's registered memory architecture. Builders requiring unbuffered UDIMMs, SODIMMs, or non-ECC memory for workstation or consumer platforms cannot use this part.

Registered ECC architecture decides fit

The 288-pin RDIMM registered buffer and on-die ECC are mandatory for the Supermicro H14DSG-O-CPU memory controller. A UDIMM or non-ECC module will not be recognised, so this specification is the sole determinant of compatibility.

Questions about this item

Does the package include anything besides the 128GB DDR5 5600MHz CL46 RDIMM module?

The box contains a single 128GB DDR5 5600MHz PC5-44800 2Rx4 1.1V CL46 288-pin ECC Registered RDIMM. No cables, brackets, heat spreaders or additional components are included.

Should I choose the 2Rx4 registered ECC version or would a UDIMM work in the Supermicro H14DSG-O-CPU?

The Supermicro H14DSG-O-CPU motherboard requires 288-pin Registered (RDIMM) modules. A UDIMM or SODIMM will not fit or function; the 2Rx4 registered ECC configuration matches the board's memory-population rules.

Will the CL46 timing and 1.1V voltage run automatically at 5600MHz once installed in the H14DSG-O-CPU?

Yes. The module's exact rank, voltage and timing match what the server's memory controller expects, so it is recognised at full capacity and operates at its rated DDR5 5600 speed without manual configuration.
