Exact-match DDR5 upgrade kit

This 192GB kit contains four 48GB DDR5-6400 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14DST-F memory controller expects. It is designed for administrators who need the full capacity recognised at rated speed without manual tuning.

Registered ECC headroom at CL52

The 2Rx8 organisation and registered architecture let every slot run fully populated at 1.10V while ECC corrects single-bit errors on the fly. Capacity stops at 192GB, so workloads that scale beyond that will need a platform with higher per-slot limits or additional memory channels.

Kit-only delivery

The package supplies the four RDIMMs and nothing else — no heat spreaders, no software utilities and no cables. Installation must follow the motherboard manual's population order and supported-capacity tables for the H14DST-F.

Questions about this item

Will the 48 GB DDR5-6400 RDIMMs work in the remaining slots if I keep some existing DDR5 modules?

The kit is validated for the Supermicro H14DST-F motherboard; mixing modules of different speeds or ranks is not tested by the manufacturer.

How can I confirm the kit is running at DDR5-6400 CL52 1.1 V after installation?

Enter the BIOS or use a hardware-monitoring utility to verify the memory frequency reads 6400 MT/s, CAS latency 52 and voltage 1.10 V.

What ships in the box and is anything else required for installation?

The box contains the 192 GB (4 × 48 GB) DDR5-6400 ECC Registered RDIMM kit; no additional parts are needed for a standard server DIMM slot installation.
