Speed 6400MHz

  • 256GB kit enables full-capacity server workloads with 2x128GB DDR5 6400 modules
  • Registered ECC architecture corrects single-bit errors preventing silent data corruption and unplanned reboots
  • 1V operation at CL52 latency matches controller expectations for stable rated-speed performance
  • 288-pin RDIMM form factor fits Supermicro H14SSL-N motherboard memory slots exactly
  • 2Rx4 dual-rank organization supports full population across all slots at maximum capacity

256GB DDR5 ECC RDIMM kit

This 256GB kit contains two 128GB DDR5 registered DIMMs built for Supermicro H14SSL-N motherboards. It targets administrators upgrading or expanding memory capacity in compatible server platforms. The modules run at 6400 MT/s with CL52 latency and 1.1V operation.

Registered 288-pin form factor

Each module uses a 288-pin RDIMM design with 2Rx4 organisation and on-board ECC. Registered buffering reduces electrical load on the memory controller when all slots are populated. The lack of a heat spreader means airflow across the PCB must be provided by the chassis.

Replaces smaller or slower DDR5 RDIMMs

The jump is worth it when your workload needs the full 256GB at rated 6400 speed and the motherboard supports this exact rank and voltage configuration. It is not for systems that require UDIMM, SODIMM, or non-ECC memory.

Questions about this item

Does DDR5 6400 (PC5-51200) run at 6400 MT/s on the Supermicro H14SSL-N?

Yes, the kit is rated DDR5 6400 (PC5-51200) and the motherboard supports that speed when populated per its memory rules.

Will these 288-pin RDIMMs fit the H14SSL-N DIMM slots?

The modules are 288-pin Registered RDIMMs, the exact form factor the H14SSL-N requires; UDIMMs or SODIMMs will not fit.

What population order should I follow when installing both 128 GB modules?

Consult the H14SSL-N manual for the approved DIMM population sequence; installing in the wrong slots can prevent the system from recognising the full 256 GB capacity.
