64 GB DDR5 6400 ECC RDIMM for Supermicro H14DST-F

This 64 GB DDR5 6400 (PC5-51200) registered ECC module is built to the exact rank, voltage and timing the Supermicro H14DST-F memory controller expects. It targets administrators upgrading or populating that specific motherboard with server-grade memory that is recognised at full capacity and rated speed.

Capacity and headroom: 64 GB per module at CL52

A single 64 GB 2Rx4 RDIMM delivers high density for virtualisation, database or compute workloads that benefit from large memory footprints. Registered buffering allows full-slot population without overloading the controller, while ECC corrects single-bit errors on the fly. Systems requiring more total memory than one module provides, or boards that only accept unbuffered UDIMMs, cannot use this part.

What the kit changes

The package supplies one 288-pin RDIMM matched to the H14DST-F population rules, so the firmware detects it immediately and runs at DDR5 6400 without manual tuning. Registered architecture and on-die ECC maintain stability across every populated slot, reducing silent data corruption and unplanned reboots in production environments.

Questions about this item

Will this 64GB DDR5 6400 CL52 RDIMM run at rated speed alongside existing slower DDR5 modules in my Supermicro H14DST-F?

The motherboard will clock all installed DDR5 to the speed of the slowest module, so this 6400 kit will downshift if paired with slower memory.

How can I verify the 2Rx4 1.1V ECC RDIMM is recognised at full 64GB capacity after installation?

Enter the BIOS or UEFI on the H14DST-F and confirm the memory information screen shows 64GB at 6400 MT/s with ECC active.

Does the package contain only the single 64GB DDR5 6400 RDIMM or are additional parts such as heat spreaders included?

The box includes the 64GB DDR5 6400 2Rx4 1.1V CL52 288-pin ECC RDIMM only; no heat spreader or extra accessories are supplied.
