Exact-match 512GB DDR5-6400 kit for Supermicro

This NEMIX RAM kit delivers 512GB of DDR5-6400 ECC registered memory across 16 modules of 32GB each. It is built for servers that require the 288-pin RDIMM form factor, 1.1V operation and CL52 timing. The 2Rx8 rank layout matches the memory controller expectations of the supported platform.

Replaces partial or mismatched DDR5 populations

When a server runs with fewer than 16 modules or with mixed ranks, the memory controller may down-clock or limit total capacity. This kit provides a full, homogeneous population so every slot runs at the rated 6400 MT/s speed and the full 512GB is recognised. The jump is worth it when the workload demands maximum registered ECC capacity at the board's top supported data rate.

Verify DIMM population rules

Supermicro H13DSG-OM motherboards enforce specific population sequences and per-channel limits that differ by CPU configuration. Consult the board manual for the approved installation order, maximum capacity per channel and any BIOS version requirements. The modules have no heat spreader, so ensure chassis airflow meets the vendor's thermal guidelines for fully populated registered DIMMs.

Questions about this item

Will these 288-pin DDR5 RDIMM modules fit the Supermicro H13DSG-OM motherboard slots?

Yes, the 288-pin Registered DDR5 form factor matches the H13DSG-OM memory slots exactly; the kit is verified for that board.

What is the correct installation order for the 16 modules in this 512GB kit?

Follow the H13DSG-OM manual's DIMM population sequence; installing in the wrong channel order is the most common mistake that prevents full capacity recognition.

How do I know if a module in this 16 x 32GB kit needs replacement later?

ECC corrects single-bit errors automatically; persistent multi-bit errors or repeated POST memory failures indicate a module that should be swapped under lifetime replacement.
