Exact-match DDR5-6400 server kit

This 384GB kit delivers six 64GB DDR5-6400 RDIMMs built to the precise rank, voltage and timing the Supermicro H14SSL-N memory controller expects. The modules are registered ECC 2Rx4 parts that install in the board's 288-pin slots and run at the rated 6400 MT/s speed without manual tuning.

Registered ECC limits and population rules

Registered architecture buffers each address line so all six slots can be fully populated at the rated 6400 speed, while on-die ECC corrects single-bit errors before they reach the OS. The motherboard manual defines the approved DIMM population order and maximum capacity per channel; exceeding those limits will prevent the system from posting at the rated speed.

Bare-module build and daily implications

The sticks ship without heat spreaders, relying on chassis airflow for cooling in dense server configurations. Their 288-pin RDIMM form factor fits only registered DIMM slots — UDIMM or SODIMM sockets will not accept them — so the kit is restricted to platforms that explicitly list RDIMM support in their qualified-vendor lists.

Questions about this item

Should I choose the 384GB kit or a different capacity for my Supermicro H14SSL-N?

This kit provides 384GB using six 64GB modules. Check your motherboard manual for the supported maximum capacity and the approved DIMM population order before deciding.

What does the DDR5 6400 speed mean once installed in the H14SSL-N?

The modules are rated at 6400 MT/s (PC5-51200). The server's memory controller will run them at the highest speed the CPU and BIOS support for a fully populated six-DIMM configuration.

Is the 288-pin RDIMM interface compatible with my board and what does it cap in practice?

Yes — the H14SSL-N requires 288-pin Registered RDIMMs. The registered design lets all six slots run at full capacity, while ECC corrects single-bit errors on the fly.
