  • Lifetime replacement warranty with US-based technical support backs the upgrade

Capacity and Compatibility

This 256GB kit contains two 128GB DDR5 RDIMMs built for servers that require Registered ECC memory. It is designed for the Supermicro H14SST-GE motherboard and matches the board's population rules.

Registered ECC Architecture

The modules run at DDR5 6400 with CL52 latency at 1.10V using a 2Rx4 organization. Registered buffering reduces electrical load on the memory controller so every slot can be fully populated at rated speed while ECC corrects single-bit errors.

Server Build Integration

The 288-pin RDIMM form factor fits only boards wired for Registered DDR5, not UDIMM or SODIMM slots. Verify your system manual for approved capacities and DIMM order before installation.

Questions about this item

What does the 6400 MT/s rating mean once the kit is installed in the Supermicro H14SST-GE?

The modules run at DDR5 6400 (PC5 51200) with CL52 latency at 1.10 V, so the memory controller sees the rated speed and timings without manual tuning.

How does the 288-pin RDIMM interface and registered design affect maximum capacity on this board?

The 288-pin Registered DIMM form factor is what the H14SST-GE requires; the registered architecture lets the board run every slot fully populated at 256 GB total without overloading the memory controller.

What physical clearance do the 128 GB modules need inside the server chassis?

Each 288-pin RDIMM has no heat spreader, so standard DIMM-slot height clearance is sufficient; verify the motherboard manual for population order before installing the 2x128 GB kit.
