Exact-match DDR5-6400 kit for Supermicro X14DBG-LC+

This 512 GB kit contains four 128 GB registered ECC RDIMMs built to the DDR5-6400 (PC5-51200) standard. Each module runs at 1.10 V with CL52 latency and a 4Rx4 organisation. The 288-pin form factor matches the board's memory slots precisely.

Capacity and headroom

Four fully populated slots deliver 512 GB of registered ECC memory, letting the memory controller drive every channel at rated speed. The registered architecture offloads electrical load so all slots remain stable at maximum capacity. ECC corrects single-bit errors on the fly, preventing silent data corruption. Workloads that exceed 512 GB or require higher frequencies will need a different platform.

Build integration

The modules plug directly into the Supermicro X14DBG-LC+ motherboard's 288-pin RDIMM slots — no UDIMM or SODIMM alternative fits. Installers must follow the board's population order and capacity limits from the system manual. No heat spreaders are present, so airflow across the DIMMs must be adequate. The kit frees all remaining expansion slots and storage bays for other components.

Questions about this item

Will this 512GB kit work alongside any existing DDR5 6400 RDIMM modules I keep in my Supermicro X14DBG-LC+?

Mixing ranks or timings can prevent full-speed operation; for reliable 6400 MT/s performance populate all slots with identical 4Rx4 CL52 1.1V modules.

How can I verify the kit is running at DDR5 6400 CL52 after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm 6400 MT/s data rate and CL52 latency on all four 128GB DIMMs.

What exactly ships in the box and is anything else required?

The box contains four 128GB 288-pin DDR5 ECC Registered RDIMMs; no extra cables, brackets or software are needed for installation.
