Exact-match DDR5 server upgrade

This 512GB kit contains four 128GB DDR5-6400 RDIMMs built to the precise rank, voltage and timing the Supermicro X14SDW-64C-SP9F expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. It is designed for administrators who need maximum supported capacity in that specific platform.

Capacity and headroom

Four 128GB 4Rx4 modules deliver 512GB total at 1.1V with CL52 latency, filling the board's DDR5 slots to their rated limit. The registered buffer offloads the memory controller so the full configuration remains stable under sustained server workloads. Builders requiring more memory than this kit provides must consult the motherboard manual for larger supported configurations.

DDR5 interface limits

The 288-pin RDIMM form factor fits only DDR5 registered DIMM slots; it will not work in UDIMM or SODIMM sockets. Population rules and maximum supported capacities vary by motherboard revision and BIOS version, so the system manual must be checked before installation. Mixing these modules with different ranks, voltages or speeds can prevent the server from posting at the rated 6400 MT/s.

Questions about this item

Will the 4Rx4 1.1V DDR5 RDIMMs work with existing DDR5 modules already installed in my Supermicro X14SDW-64C-SP9F?

Mixing ranks or voltages is not recommended; the board's memory controller expects identical 4Rx4 1.1V DDR5-6400 RDIMMs in every populated slot to run at the rated 6400 MT/s without down-clocking or instability.

How can I confirm the kit is running at DDR5-6400 CL52 with ECC active after installation?

Enter the BIOS or use a tool like dmidecode to verify each DIMM reports 6400 MT/s, CL52 latency, 1.1 V, Registered ECC mode, and that the total 512 GB is recognised without errors.

Does the 512 GB kit include only the four 128 GB RDIMMs, or are any cables, brackets or licences supplied?

The package contains exactly the four 128 GB 288-pin DDR5-6400 CL52 1.1 V ECC Registered RDIMMs; no cables, brackets, heatsinks or software licences are included.
