Exact-Match DDR5 ECC RDIMM Kit

This 1.5 TB kit contains twelve 128 GB DDR5-6400 registered ECC modules built to the precise rank, voltage, and timing the Supermicro H13DSG-OM memory controller expects. It is intended for administrators who need the full supported capacity recognised at rated speed without manual tuning. Buyers whose boards require UDIMM or SODIMM form factors cannot use this kit.

Capacity and Headroom

Twelve dual-rank 2Rx4 modules deliver 1.5 TB across every slot, running at CL52 and 1.1 V. Registered architecture offloads the memory controller so all slots stay fully populated at full speed, while ECC corrects single-bit errors on the fly. Systems that cannot address this density or that limit registered DIMM count will not benefit from the full kit.

Build Integration

The 288-pin RDIMM form factor matches the H13DSG-OM slot specification exactly; no UDIMM or SODIMM alternative fits. Consult the motherboard manual for approved population order and maximum supported capacity before installation. Major-brand Samsung, Micron, or Hynix DRAM ensures consistent supply for future expansion within the same validated configuration.

Highlights

  • 5 TB total capacity from twelve 128 GB modules

Questions about this item

Will the 12 modules run at DDR5 6400 CL52 when I add them to the existing DIMMs already installed in my H13DSG-OM?

The kit is spec-matched to the board's memory-population rules, but full-speed operation depends on the manual's approved DIMM order and maximum supported capacity per channel.

How can I confirm the 1.5 TB kit is recognised at full capacity and correct speed after installation?

Check the BIOS memory information screen or the operating system's memory report for 1.5 TB total, DDR5 6400 (PC5-51200) speed, CL52 timings and 1.10 V voltage.

Does the MR51200-724K12 package include anything besides the twelve 128 GB RDIMMs?

The package content lists only the 12 x 128 GB DDR5 6400 CL52 1.1 V 288-pin ECC RDIMM modules; no cables, brackets or additional accessories are included.
