  • 1 V operation matches the motherboard's memory controller specification exactly
  • Major OEM Samsung, Micron or Hynix chips provide enterprise-grade component reliability

Exact-match DDR5-6400 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5-6400 Registered ECC RDIMMs built to the 2Rx8, 1.1V, CL52 specification the Supermicro H14SSL-N memory controller expects. The modules are verified for full-capacity recognition at rated speed without manual tuning.

DDR5-6400 speed ceiling and population rules

The DDR5-6400 interface defines the maximum data rate this kit can deliver; the board's memory controller and population rules determine the actual operating frequency when all slots are filled. Registered architecture offloads the controller so every slot can run populated, but the final speed depends on the platform's qualified-vendor list.

Replaces slower or smaller DDR5 RDIMMs

The jump is worth it when the server needs the full 256GB capacity at the board's top qualified DDR5 speed with ECC protection. Systems that require UDIMMs, SODIMMs, non-ECC modules, or lower-density DIMMs cannot use this kit.

Questions about this item

Should I choose the 256GB kit or a smaller capacity for my Supermicro H14SSL-N?

The kit provides 256GB across eight 32GB modules, fully populating the board for maximum registered ECC capacity at DDR5-6400.

What does the DDR5-6400 rating deliver once installed in the server?

The modules run at 6400 MT/s with CL52 latency at 1.1V, giving the memory controller its rated bandwidth of PC5-51200.

How does the 288-pin RDIMM interface and registered design affect real-world limits?

Registered buffering lets all eight slots operate at full 32GB density, while ECC corrects single-bit errors on the fly.
