  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 128 GB total capacity from eight 16 GB modules
  • DDR5 6400 speed with CL52 latency for rated performance
  • Registered ECC design corrects single-bit errors automatically
  • 1 V operation matches the motherboard specification exactly
  • 288-pin RDIMM form factor fits the Supermicro H14SSL-NT motherboard

Server DDR5 RDIMM kit

This 128 GB kit contains eight 16 GB DDR5 6400 registered ECC modules rated at CL52 and 1.10 V. The 288-pin RDIMM form factor matches the Supermicro H14SSL-NT motherboard requirements for full-capacity population.

Suited for registered ECC platforms

Ideal for administrators upgrading a Supermicro H14SSL-NT system that demands registered ECC DDR5 at the specified rank, voltage and timing. Not suitable for builds needing unbuffered UDIMM modules, SODIMM form factors, or non-ECC memory.

Eight-slot headroom

Eight 1Rx8 modules fill every slot on the target board, delivering the full 128 GB at DDR5-6400 without down-clocking. Systems requiring more than 128 GB or a different rank configuration will need a separate solution.

Questions about this item

Must my Supermicro H14SSL-NT motherboard already support DDR5 6400 RDIMM ECC Registered memory for this 128GB kit to function?

Yes. The kit requires a motherboard that accepts 288-pin DDR5 RDIMM modules with ECC and registered buffering. The H14SSL-NT is listed as compatible, but you should confirm the board's qualified-vendor list and population rules before installing.

Can I mix these 1Rx8 CL52 1.10V modules with older DDR5 RDIMMs of different rank or latency in the same server?

Mixing ranks, latencies or voltages is not recommended. The memory controller will down-clock all channels to the slowest common timing, and population rules for the H14SSL-NT may prohibit mixed configurations. Use identical modules for guaranteed stability.

How do I verify the full 128GB is recognised and running at 6400 MT/s with ECC active after installation?

Enter the system BIOS or UEFI and check the memory information screen. It should show 128GB total, 6400 MT/s data rate, CL52 timings, 1.10V voltage and ECC enabled. You can also confirm with operating-system tools such as dmidecode or lshw.
