512 GB DDR5 ECC RDIMM kit for Supermicro H14SST-G

This 512 GB kit contains four 128 GB DDR5 5600 registered ECC RDIMMs built to the exact specifications of the Supermicro H14SST-G motherboard. It is intended for administrators who need maximum registered capacity on this specific platform.

Check motherboard manual for DIMM population rules

Verify the Supermicro H14SST-G manual for supported capacities, approved population order and installation steps before ordering. The board requires 288-pin registered RDIMMs and will not accept UDIMM or SODIMM modules. Ensure the BIOS is current for full 512 GB recognition.

Registered design offloads the memory controller

Registered architecture reduces electrical load on the memory controller when all slots are populated, while ECC corrects single-bit errors during operation. Modules run at 1.10 V with CL46 latency and have no heat spreader.

Questions about this item

What is included in the 512GB kit and do I need to buy any additional modules?

The kit contains four 128GB DDR5 5600 CL46 ECC RDIMM modules for a total of 512GB. No extra modules are required to reach the rated capacity.

How do I decide between this 512GB 4x128GB kit and a smaller capacity option?

Choose this kit when your Supermicro H14SST-G motherboard supports full population of four 2Rx4 registered DIMMs and you need the maximum 512GB capacity at DDR5 5600 speed.

What does the DDR5 5600 (PC5-44800) rating mean once the memory is installed in the server?

The modules will run at 5600 MT/s with CL46 latency at 1.1V, delivering the rated bandwidth and registered ECC stability the H14SST-G memory controller expects.
