256GB DDR5-5600 ECC RDIMM kit for Supermicro

This 256GB kit contains four 64GB DDR5-5600 registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H14SST-G memory controller expects. The modules operate at 1.1V with CL46 latency and use the 288-pin RDIMM form factor required by this motherboard. It is intended for administrators who need to populate all slots with validated capacity.

Registered architecture

Registered buffering offloads the memory controller so every slot runs fully populated at the rated 5600 MT/s speed, while ECC corrects single-bit errors on the fly to prevent silent data corruption. The 2Rx4 organisation and 1.1V operation match the board's electrical requirements for sustained enterprise workloads. Stability is maintained across continuous operation without downclocking.

Verify manual population rules before ordering

Server memory support varies by model, so consult the system or motherboard manual for supported capacities, approved DIMM population order and installation steps. The kit requires four available 288-pin RDIMM slots and a platform that accepts 2Rx4 registered ECC modules at 1.1V. Buyers needing a different capacity, rank configuration or unbuffered memory should look elsewhere.

Questions about this item

How much power does the 256GB DDR5 5600 kit draw at 1.1V under continuous load?

The kit runs at 1.1V with CL46 timing; registered ECC modules at this voltage typically draw modest power per DIMM, so the four 64GB sticks together stay within normal server memory power envelopes for all-day operation.

What motherboard slot type is required to install these 288-pin RDIMMs?

The Supermicro H14SST-G must provide 288-pin DDR5 RDIMM slots; the kit will not fit UDIMM or SODIMM sockets and requires the board's registered memory population rules to be followed.

Will the 2Rx4 registered ECC modules work in a system that currently uses 1Rx8 unbuffered DDR5?

No, registered RDIMMs and unbuffered UDIMMs cannot be mixed; the memory controller expects registered modules with ECC, so all slots must be populated with matching registered DIMMs.
