  • DDR5 5600 speed with CL46 latency at 1.1 V
  • Registered ECC design prevents data errors under load
  • 288-pin RDIMM form factor built for Supermicro H14SHM
  • 2Rx4 rank layout matches server memory controller expectations

Exact-match server kit

This 512GB kit contains four 128GB DDR5-5600 RDIMM modules built to the exact rank, voltage and timing the Supermicro H14SHM motherboard expects. Registered ECC architecture offloads the memory controller so every slot runs fully populated at rated speed while correcting single-bit errors on the fly.

Replaces mixed or undersized DIMMs

The jump is worth it when your current configuration uses smaller capacities, mixed ranks or unbuffered modules that prevent full population or force downclocking. This kit delivers the precise 2Rx4 1.1V CL46 specification required for stable operation at maximum supported density.

Suits H14SHM builders at scale

Ideal for administrators populating all available slots with validated Registered ECC memory for production workloads. Not for systems that require UDIMM or SODIMM form factors, boards limited to lower maximum capacities, or configurations that cannot accept 2Rx4 registered modules.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Supermicro H14SHM motherboard slots?

Yes, the kit uses 288-pin DDR5 RDIMM form factor, which is the exact slot type the Supermicro H14SHM requires. UDIMM or SODIMM modules will not fit or work in this board.

What population order should I follow when installing the four 128 GB modules?

Install all four modules in the sequence specified in the Supermicro H14SHM manual; the board has specific DIMM population rules for full-capacity operation with 2Rx4 registered DIMMs.

Do these modules have a heat spreader that could need cleaning or replacement?

No, the modules are built without a heat spreader, so there is no spreader to clean, re-seat, or replace during the product's lifetime.
