192GB DDR5-6400 ECC RDIMM kit

This 192GB kit contains two 96GB DDR5-6400 Registered ECC RDIMMs built for the Supermicro H14DST-FL motherboard. The modules run at CL52 latency and 1.1V, matching the board's memory-controller expectations so full capacity is recognised at rated speed. Enterprise workloads that need error correction and registered buffering gain the stability this spec provides. Builders using consumer UDIMMs or SODIMMs cannot use this kit.

Registered RDIMM installation notes

The 288-pin Registered RDIMM form factor fits only motherboards designed for registered memory; it will not seat in UDIMM or SODIMM slots. Consult the Supermicro H14DST-FL manual for the approved DIMM population order and maximum supported capacity per channel before installing. Incorrect slot population or exceeding the board's validated configuration can prevent boot or limit usable capacity. No heat spreader is present, so airflow across the modules must be adequate.

Capacity headroom for dense workloads

Two 96GB ranks deliver 192GB total, suited to virtualisation hosts, in-memory databases and large-container deployments that benefit from registered ECC at DDR5-6400 speeds. Workloads requiring more than 192GB per two-DIMM kit, or systems that do not support Registered ECC RDIMMs, will need a different memory configuration. The CL52 timing and 1.1V operation keep power draw predictable within the platform's validated envelope.

Questions about this item

How do I verify the kit runs at DDR5 6400 CL52 after installation?

Enter the BIOS and confirm the memory speed shows 6400 MT/s with CL52 timings; the registered ECC design ensures each 96 GB module is recognized at full capacity.

What does the 192 GB kit include and what must I source separately?

The kit contains two 96 GB 288-pin DDR5 RDIMMs; no heat spreaders or extra cables are included, and the motherboard manual is required for the approved DIMM population order.

Which version should I choose for the Supermicro H14DST-FL?

Select the 192 GB (2 x 96 GB) DDR5 6400 CL52 2Rx4 1.1 V registered ECC RDIMM kit — it matches the board's required rank, voltage, timing and 288-pin form factor.
