Exact DDR5-5600 ECC RDIMM kit for Supermicro

This 128GB kit contains eight 16GB registered DIMMs built to the DDR5-5600 (PC5-44800) standard with CL46 timing and 1.1V operation. It targets administrators who need the precise rank, voltage and latency their server's memory controller expects for full-capacity recognition at rated speed.

Registered DDR5 architecture limits

The registered design buffers address and command signals so the memory controller can drive a fully populated bank of 288-pin RDIMM slots without signal degradation. ECC corrects single-bit errors on the fly, but the modules will not function in boards that require unbuffered UDIMMs or SODIMMs.

Verify population rules before ordering

Consult the Supermicro H14SST-G manual for supported total capacities, approved DIMM population order and any BIOS requirements for 1Rx8 registered modules. Systems that demand different ranks, voltages or form factors cannot use this kit.

Questions about this item

Should I choose the 8 x 16 GB kit or a different capacity for my Supermicro H14SST-G?

The 128 GB kit ships as eight 16 GB modules, matching the board's 288-pin RDIMM slots and registered ECC requirements for full-capacity operation.

What does the DDR5 5600 speed mean once the modules are installed in the server?

The memory runs at 5600 MT/s with CL46 latency at 1.1 V, delivering the rated PC5-44800 bandwidth the motherboard's memory controller expects.

How does the 288-pin RDIMM interface and registered ECC design affect real-world use?

Registered buffering lets all eight slots run fully populated at 5600 MT/s while ECC corrects single-bit errors on the fly to prevent silent data corruption.
