768GB DDR5-5600 ECC RDIMM Kit

This 768GB kit contains six 128GB DDR5-5600 registered ECC RDIMMs built for the Supermicro H13SSH motherboard. Each module runs at 1.10V with CL46 latency and a 2Rx4 organization. The 288-pin registered design matches the board's memory-controller requirements for full-capacity recognition at rated speed.

Suited for H13SSH servers needing maximum

Administrators populating every DIMM slot on a Supermicro H13SSH with registered ECC modules will use this exact-match kit. Builders who need unbuffered UDIMMs, SODIMMs, lower total capacity, or a different memory generation should look elsewhere because this kit only fits registered DDR5 RDIMM platforms.

Registered 2Rx4 DDR5-5600 at 1.10V

The registered 2Rx4 architecture at DDR5-5600 and 1.10V is the single specification that decides compatibility. The motherboard's memory controller expects this exact rank, voltage, and timing combination to initialize all six modules at full 768GB capacity without downclocking or population errors.

Questions about this item

Does my Supermicro H13SSH motherboard need all six slots filled for this 768 GB kit to run at DDR5-5600?

The kit contains six 128 GB modules built for the 288-pin RDIMM slots on the H13SSH. Consult the board manual for the approved population order so the memory controller recognises the full 768 GB at the rated 5600 MT/s speed.

Can I keep any DDR5 UDIMMs I already own and add these registered modules alongside them?

No. These are 288-pin registered ECC RDIMMs, while UDIMMs are unbuffered and use a different electrical interface. Mixing them would prevent the system from posting.

After installation, how do I confirm the kit is running at the specified CL46 latency and 1.1 V?

Enter the BIOS or use a hardware-monitoring utility to verify the memory reports DDR5-5600, CL46 timings and 1.10 V operation across all six modules.
