  • 768 GB total capacity from sixteen 48 GB modules for dense server workloads
  • DDR5 4800 speed with CL40 latency matches the board's rated timing
  • 2Rx8 registered ECC design offloads the memory controller and corrects single-bit errors
  • 1 V operation at 288-pin RDIMM form factor fits the Supermicro H13DSH exactly
  • Major OEM Samsung Micron Hynix chips provide enterprise-grade component consistency

Exact-match server upgrade

This 768GB kit contains 16 DDR5 RDIMMs of 48GB each, running at 4800MHz with CL40 latency and 1.1V operation. Registered ECC design with 2Rx8 organisation matches the Supermicro H13DSH memory controller requirements for full-capacity recognition.

Supermicro H13DSH deployments

Suited for administrators populating all memory channels on the H13DSH platform with registered ECC modules. Not suitable for systems that require UDIMM or SODIMM form factors, or for boards that do not support registered memory population rules.

Sustained enterprise workloads

Registered buffering reduces electrical load on the memory controller, allowing all 16 slots to operate at rated speed continuously. ECC corrects single-bit errors in real time, preventing silent data corruption during extended compute or database tasks.

Questions about this item

Does my Supermicro H13DSH motherboard need all 16 DDR5 slots filled to use this 768GB kit?

The kit contains 16 RDIMMs and the board has 16 DDR5 slots. Consult the motherboard manual for supported population rules; full capacity is reached when every slot is occupied.

Will these 2Rx8 registered DDR5 modules work alongside any older RDIMMs I leave in the system?

Registered ECC DDR5 RDIMMs of this speed and rank must match the board's qualified-vendor list. Mixing different ranks, speeds or voltages can prevent the system from posting at the rated 4800 MT/s.

How do I confirm the full 768GB is running at DDR5-4800 CL40 after installation?

Enter the BIOS or use a hardware-inventory tool such as dmidecode or IPMI to verify each slot shows 48GB, 4800 MT/s, CL40, 1.1 V and ECC active.
