  • Total capacity96 GB (2 × 48 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 96 GB capacity for memory-intensive server workloads
  • DDR5 6400 speed with CL52 latency for rated performance
  • Registered ECC design corrects single-bit errors automatically

  • 288-pin RDIMM form factor fits Supermicro H14SST-GE motherboard

Exact-match server upgrade

This NEMIX RAM kit delivers 96GB of DDR5 memory as two 48GB registered ECC RDIMMs. The modules run at 6400MHz with CL52 latency and 1.1V operation, matching the Supermicro H14SST-GE motherboard requirements for full-capacity recognition and rated-speed performance. The 2Rx8 rank configuration and registered architecture are precisely what the platform's memory controller expects.

Replaces mixed or smaller kits

Upgrading from mismatched capacities, lower speeds, or unbuffered UDIMMs eliminates population-rule conflicts and lets every slot run fully populated at the rated 6400MHz. The jump is worth it when your workload demands maximum registered ECC capacity with guaranteed compatibility rather than trial-and-error mixing of generic modules.

Suits Supermicro H14SST-GE deployments

This kit suits administrators populating the Supermicro H14SST-GE with validated 96GB registered ECC memory for production stability. Builders needing UDIMM, SODIMM, or non-ECC modules should look elsewhere, as the 288-pin RDIMM form factor and registered architecture are mandatory for this platform.

Questions about this item

Does this 288-pin DDR5 RDIMM kit fit the Supermicro H14SST-GE motherboard's memory slots?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor required by the Supermicro H14SST-GE motherboard. The 2Rx8 registered ECC modules match the board's memory-population rules for full-capacity recognition at DDR5-6400 speed.

What is the correct installation order for the two 48GB modules on the Supermicro H14SST-GE motherboard?

Consult the Supermicro H14SST-GE motherboard manual for the approved DIMM population sequence. The board's memory controller requires specific slot filling order to initialise both 48GB 2Rx8 registered ECC modules at CL52 1.10V DDR5-6400.

Will the registered ECC RDIMM modules require any firmware updates or ongoing maintenance after installation?

No firmware updates are needed for the DDR5 RDIMM modules themselves. ECC error correction operates automatically on the 2Rx8 chips. Verify BIOS recognises the full 96GB kit at 6400MHz CL52 1.10V after installation.
