768GB DDR5 5600 ECC RDIMM kit

This NEMIX RAM kit delivers 768GB across 12 modules of 64GB each, running at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V. It uses 288-pin Registered ECC RDIMM form factor built with major OEM chips. The kit is validated for the Supermicro H14DSG-O-CPU motherboard.

Suited servers and limits

Ideal for administrators expanding the Supermicro H14DSG-O-CPU to maximum registered ECC capacity with a single matched kit. Not suited for builds needing unbuffered UDIMM or SODIMM modules, or for platforms that cannot accept 2Rx4 registered DIMMs at this voltage and timing.

Decisive specification

The registered ECC RDIMM architecture with 2Rx4 organization at 1.1V CL46 is the single spec that determines whether the motherboard will recognise all 12 slots at full speed.

Highlights

  • 768 GB total capacity from twelve 64 GB modules for high-density server workloads

Questions about this item

Does the Supermicro H14DSG-O-CPU motherboard need a specific BIOS revision to recognise the 768GB 12x64GB DDR5 5600 CL46 kit?

The kit is validated for the Supermicro H14DSG-O-CPU; follow the motherboard manual for supported capacities, approved DIMM population order and installation steps before purchase.

Can I mix these 2Rx4 Registered ECC RDIMMs with any unbuffered UDIMMs already installed in the Supermicro H14DSG-O-CPU?

No, the board requires 288-pin Registered RDIMMs; mixing with UDIMMs is not supported and will prevent the system from running at the rated 5600 speed.

After installing all twelve 64GB modules, how do I confirm the server is running the full 768GB at DDR5 5600 CL46?

Check the BIOS memory summary or OS tools — they should show 768GB total, 5600 MT/s data rate and CL46 latency for every populated slot.
