  • 64 GB total capacity from two 32 GB modules for high-density server workloads
  • DDR5 4800 speed rated at PC5-38400 delivers rated bandwidth without down-clocking
  • CL40 CAS latency at 1.1 V matches the memory controller timing for stable operation
  • Registered ECC architecture with 2Rx8 organisation corrects single-bit errors and supports full-slot population
  • 288-pin RDIMM form factor verified for Supermicro H13SVW-NT-OS1 motherboard compatibility

System-Specific DDR5 ECC Kit

This 64 GB kit contains two 32 GB DDR5-4800 registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13SVW-NT-OS1 memory controller expects. It installs as a matched pair so the server recognises the full capacity at rated speed without manual configuration.

Thermals and Power at CL40 1.10 V

Operating at 1.10 V with CL40 latency, the modules draw minimal power and run without heat spreaders, relying on the chassis airflow the Supermicro platform already provides. Registered buffering reduces electrical load on the memory controller, keeping temperatures steady even when every slot is populated.

What the Kit Changes

The package delivers only the two 288-pin RDIMMs; no extra cables, software or cooling hardware are included. Compatibility is limited to systems that accept DDR5 registered ECC memory in a 2Rx8 organisation, so builders needing unbuffered UDIMMs or a different rank configuration must look elsewhere.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the Supermicro H13SVW-NT-OS1 and which population rule is often missed?

Power off the server, open the chassis, and insert each 32 GB module into the slots specified by the motherboard manual for a two-DIMM configuration; the step most often missed is following the exact slot order required for dual-channel operation.

What maintenance or replacement will the ECC RDIMM kit need over its service life?

No routine maintenance is required; if a module fails it is covered by the manufacturer's lifetime replacement warranty, and the registered ECC design helps prevent silent data corruption during operation.

What limit appears first when the 64 GB DDR5-4800 kit runs sustained workloads?

The registered buffer and ECC logic keep every slot stable at the rated 4800 MT/s speed and 1.1 V, so the first practical limit is the motherboard's maximum supported capacity rather than memory throttling.
