768GB DDR5 ECC RDIMM kit for Supermicro H13SST-G

This 768GB kit contains six 128GB DDR5 4800 Registered ECC RDIMMs built to the exact rank, voltage and timing the motherboard expects. Each module is a 288-pin 2Rx4 DIMM operating at 1.1V with CL40 latency. The Registered architecture lets every slot run fully populated at rated speed while ECC corrects single-bit errors on the fly.

Who this suits and who should look elsewhere

This kit suits administrators upgrading a Supermicro H13SST-G motherboard that requires Registered DDR5 ECC memory in a six-module population. Builders needing unbuffered UDIMMs, SODIMM form factors, non-ECC modules or a different total capacity should look elsewhere because this product is a spec-matched Registered RDIMM kit only.

The specification that decides fit

The motherboard must accept 288-pin DDR5 4800 Registered ECC RDIMMs with 2Rx4 organisation at 1.1V and CL40 timing; if the board's qualified-vendor list or memory-population rules call for a different rank, voltage, speed or form factor, this kit will not be recognised at full capacity.

  • Registered ECC design corrects single-bit errors automatically
  • 1 V operation matches server memory-controller requirements
