Exact-match DDR5 ECC RDIMM kit for Supermicro

This 1 TB kit contains 16 registered DIMMs of 64 GB each, built to the DDR5 6400 (PC5-51200) standard with CL52 timing and 1.10 V operation. It is designed for the Supermicro H14DSG-OD motherboard and will be recognised at full capacity and rated speed when populated according to the board's rules.

288-pin RDIMM installation follows the motherboard

Each module is a 288-pin registered DIMM; the board requires this form factor and will not accept UDIMM or SODIMM variants. Install the 16 modules in the exact population order specified by Supermicro to avoid boot failures or reduced capacity.

1 TB total capacity across 16 slots

The single specification that decides fitment is the 1 TB (16 × 64 GB) registered ECC configuration at DDR5-6400. Systems needing a different total capacity, a different rank structure, or a non-registered module type cannot use this kit.

Questions about this item

How do I confirm the kit is running at 6400 MT/s with CL52 after installation?

Enter the BIOS and verify the memory frequency reads 6400 MT/s (PC5-51200) and CAS latency shows 52; the registered ECC design lets the controller train all 16 modules at rated speed when populated per the motherboard manual.

What does the 1 TB kit contain and is anything else required?

The box holds sixteen 64 GB 288-pin DDR5 RDIMM modules (part MR51200-924K16); no extra cables, brackets or heat spreaders are included or needed for the Supermicro H14DSG-OD.

Why choose the 1 TB 16 × 64 GB 2Rx4 version over a smaller kit?

This 1 TB configuration matches the board's maximum supported capacity using 2Rx4 registered ECC modules at 1.1 V, so every slot is filled with the exact rank and voltage the memory controller expects.
