576 GB DDR5 ECC RDIMM kit for Supermicro H14DSH

This 576 GB kit contains twelve 48 GB DDR5 5600 modules built as 2Rx8 registered ECC RDIMMs. It is designed for the Supermicro H14DSH motherboard where the memory controller expects registered DIMMs with ECC at 1.1 V and CL46 timing.

Verify motherboard population rules before ordering

Consult the Supermicro H14DSH manual for supported capacities, approved DIMM population order, and installation steps. The board requires 288-pin registered RDIMMs; UDIMM or SODIMM modules will not fit or function. Confirm your system can address the full 576 GB across all populated slots.

Registered ECC design for full-slot stability

Registered architecture offloads the memory controller so every slot runs fully populated at rated speed while ECC corrects single-bit errors on the fly. Modules operate at 1.1 V without heat spreaders, relying on server chassis airflow. The 288-pin RDIMM form factor matches the H14DSH slot keying exactly.

Questions about this item

Does the 12-module kit include everything needed to populate the Supermicro H14DSH, or must additional DIMMs be purchased?

The package contains the full 576GB kit — 12 modules of 48GB each — so no extra DIMMs are required for a complete installation.

Should I choose the 48GB 2Rx8 modules or a different capacity for the H14DSH?

This kit is spec-matched to the board with 48GB 2Rx8 registered ECC DIMMs at DDR5 5600, 1.1V, CL46, ensuring full-capacity recognition and rated speed.

Will the DDR5 5600 rating actually run at 5600 MT/s once installed in the H14DSH?

Yes — the modules are exact-match for the motherboard's memory controller, so the 12 DIMMs operate at the rated DDR5 5600 (PC5-44800) speed when fully populated.
