  • 512 GB capacity across four 128 GB modules for maximum server density
  • DDR5 5600 speed with CL46 latency delivers rated throughput on supported platforms
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors
  • 1 V operation matches the board's voltage requirement for stable full-population use
  • Verified fitment for Supermicro H14SSL-NT motherboard with 288-pin RDIMM form factor

Exact-Match Server Memory Kit

This NEMIX RAM DDR5 5600 kit delivers 512 GB total capacity across four 128 GB Registered ECC RDIMMs. It is built for the Supermicro H14SSL-NT motherboard and runs at 1.1 V with CL46 timing.

Suited for Fully Populated Configurations

Administrators expanding a Supermicro H14SSL-NT to its maximum supported DIMM count will benefit from the registered architecture and on-die ECC. Builders using consumer boards or UDIMM-only platforms cannot use these modules.

2Rx4 Rank and 1.1 V Operation

The dual-rank x4 organization and 1.10 V voltage match the memory controller expectations for full-speed operation at DDR5 5600. A different rank structure or voltage would prevent the system from recognizing the full 512 GB at rated speed.

Questions about this item

Will this 512GB kit of DDR5-5600 2Rx4 RDIMMs run at full speed alongside existing DDR5 modules in my Supermicro H14SSL-NT?

Mixing ranks or speeds forces the controller to downclock every slot; populate all four channels with this matched 4x128GB kit so the board sees identical 2Rx4 timing, 1.1V voltage and CL46 latency at 5600MT/s.

How can I confirm the Supermicro H14SSL-NT is recognising all 512GB at DDR5-5600 with ECC active?

Enter the BIOS at boot and verify the memory summary shows 512GB total, 5600MT/s data rate, registered ECC status enabled and a CAS latency value of 46.

Does the package include only the four 128GB RDIMMs or are heat spreaders and installation tools supplied?

The box contains the four 288-pin DDR5 RDIMM modules; no heat spreaders or tools are included.
