Exact-Match DDR5 Server Kit

This 512GB kit delivers four 128GB DDR5-6400 Registered ECC RDIMMs built to the Supermicro H14DSH memory controller's exact rank, voltage and timing requirements. It targets administrators who need the full 512GB capacity recognised at rated speed without manual tuning.

Registered Architecture For Full Population

The 2Rx4 Registered design offloads the memory controller so every slot runs fully populated at the rated 6400 MT/s and 1.1V. Builders must follow the motherboard manual for approved DIMM population order and maximum supported capacity per channel before installation.

Lifetime Support And Verified Fitment

The bundle includes only the four matched modules; no heat spreaders, cables or software are supplied. Free US-based technical support and a lifetime replacement warranty cover the kit, but buyers must confirm their specific H14DSH revision supports this density and population rule.

Questions about this item

Will the 1.1 V operating voltage keep power draw in check when all four 128 GB RDIMMs run continuously?

Each module is rated at 1.10 V, the standard DDR5 RDIMM voltage, so the kit runs at the board's default power envelope with no extra voltage headroom needed.

Does the registered ECC design add fan noise or heat compared with unbuffered sticks?

The registered buffer reduces electrical load on the memory controller, and the modules have no heat spreader, so thermal output matches standard 288-pin DDR5 RDIMMs under sustained load.

Must the Supermicro H14DSH already be populated with a specific CPU or BIOS revision for this 512 GB kit to post?

The kit is validated for the H14DSH motherboard; you only need a CPU and BIOS that support 128 GB 2Rx4 RDIMMs at DDR5 6400 and the correct DIMM population order from the board manual.
