Speed 4800MHz

  • 64 GB capacity lets the Supermicro H13SVW-NT reach its full memory limit
  • Registered ECC design corrects single-bit errors to prevent silent data corruption
  • DDR5 4800 MT/s speed matches the board's rated frequency for stable operation
  • 1 V low voltage reduces power draw per module in dense configurations
  • 288-pin RDIMM form factor fits the exact slot type the motherboard requires

Exact-match DDR5-4800 RDIMM

This 64 GB registered ECC module runs at DDR5 4800 (PC5-38400) with CL40 latency and 1.10 V operation. The 2Rx4 dual-rank organisation and 288-pin RDIMM form factor match the memory controller expectations of the Supermicro H13SVW-NT motherboard.

Build fit and requirements

The module requires a server board that accepts registered DDR5 RDIMMs and follows the H13SVW-NT population rules for full-capacity operation. Registered buffering offloads the memory controller so every populated slot runs at rated speed, while on-die ECC corrects single-bit errors before they reach the OS.

Suited for capacity-bound servers

Ideal for administrators expanding a verified Supermicro H13SVW-NT platform where registered ECC DDR5-4800 is specified. Not suited for systems that only accept unbuffered UDIMMs, SODIMM form factors, or any memory generation other than DDR5.

Questions about this item

Will the CL40 latency become a bottleneck when this 64GB DDR5 4800 module runs sustained workloads?

CL40 is the rated CAS latency for this DDR5 4800 module; it represents the timing the memory controller expects for stable operation at full speed under continuous load.

How much heat does a registered ECC RDIMM without a spreader generate when the server runs all day?

This 1.1V DDR5 RDIMM has no heat spreader; registered buffering reduces electrical load on the controller, keeping thermals within normal server airflow limits during 24/7 operation.

Does my Supermicro H13SVW-NT motherboard need a specific BIOS version or CPU to recognise this 2Rx4 registered DIMM?

The module is spec-matched to the H13SVW-NT's 288-pin RDIMM slots and 2Rx4 population rules; consult the board manual for supported capacities and approved DIMM order before installing.
