  • 768 GB total capacity from a 12-module kit of 64 GB each
  • DDR5 4800 MT/s (PC5-38400) speed matches the board's rated frequency
  • Registered ECC RDIMM design with 2Rx4 rank corrects single-bit errors and stabilises fully populated slots
  • 10 V operating voltage and CL40 latency exactly as the Supermicro H13SSL-NT memory controller expects
  • 288-pin RDIMM form factor verified for the H13SSL-NT motherboard's memory population rules

Exact-match 768 GB DDR5 RDIMM kit for Supermicro

This 12-module kit delivers 768 GB of registered ECC DDR5-4800 memory. It is built for administrators who need the full capacity the H13SSL-NT motherboard can recognise without manual tuning.

Twelve 64 GB dual-rank modules at CL40 and 1.10 V

The 2Rx4 organisation lets every slot run fully populated at the rated 4800 MT/s speed. Headroom ends when workloads exceed the 768 GB total or demand latency lower than CL40.

Registered 288-pin RDIMMs without heat spreaders

The buffered architecture offloads the memory controller so all twelve slots operate reliably at capacity. ECC corrects single-bit errors on the fly. The bare-module design fits dense server chassis where tall spreaders would block airflow.

Questions about this item

Will this 12-module kit run correctly on my Supermicro H13SSL-NT if I keep some of my existing DDR5 RDIMMs installed?

Mixing this exact-match kit with other modules is not recommended; the board's population rules expect identical rank, voltage and timing across all populated slots for full-capacity operation.

How can I verify the kit is running at its rated DDR5 4800 CL40 settings after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should show all twelve 64 GB modules recognised at 4800 MT/s with CL40 latency.

What exactly ships in the box and is anything else required to install it?

The package contains the complete 768 GB kit — twelve 64 GB DDR5 4800 CL40 2Rx4 ECC Registered RDIMMs — and nothing else is needed for installation.
