System-specific DDR5 ECC RDIMM kit

This 128GB kit contains two 64GB DDR5 6400 registered ECC modules built for the Supermicro H14DSG-OM motherboard. It targets administrators who need the exact rank, voltage and timing the platform expects so the full capacity is recognised and runs at its rated speed.

Verified 288-pin registered form factor

The modules use the 288-pin RDIMM form factor this board requires, not UDIMM or SODIMM, and are spec-matched to the motherboard's population rules. Installation follows the manual's approved DIMM order; skipping that step is the most common reason a kit is not recognised at full capacity.

Registered architecture with ECC under load

Registered buffering offloads the memory controller so every slot runs fully populated at 6400 MT/s, while ECC corrects single-bit errors on the fly. This prevents silent data corruption and unplanned reboots during sustained production workloads.

Questions about this item

How do I verify the 128GB kit is running at DDR5 6400 CL52 after installing it in my Supermicro H14DSG-OM?

Check the BIOS memory information screen or use a tool like dmidecode; it should show both 64GB RDIMMs at 6400 MT/s, CL52, 1.10 V, registered ECC, 2Rx4 organization.

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

The package contains the 128GB 2×64GB DDR5 6400 CL52 1.10 V ECC RDIMM kit (part MR51200-924K2); no extra cables, brackets or software are included or needed.

My H14DSG-OM has multiple DIMM slots — which capacity configuration should I choose?

This 128GB kit provides two 64GB 2Rx4 registered DIMMs; follow the motherboard manual's population order for the total capacity you need.
