Exact-match upgrade kit

This 256 GB kit contains four 64 GB DDR5 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SVW-NT-OS1 memory controller expects. It is intended for administrators who need the full 256 GB capacity recognised at rated speed without manual tuning.

DDR5-4800 registered limits

The modules run at 4800 MT/s (PC5-38400) with CL40 latency at 1.1 V, the standard JEDEC profile for this generation of registered DIMMs. Registered buffering allows every slot to be populated at full capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption.

2Rx4 registered ECC requirement

The motherboard requires 288-pin DDR5 RDIMMs with 2Rx4 organisation, registered buffering and ECC; UDIMMs or SODIMMs will not fit or function. Verify the board's population rules and maximum supported capacity in the system manual before ordering.

Questions about this item

Should I choose the 256GB 4x64GB kit or a smaller capacity for my Supermicro H13SVW-NT-OS1?

The 256GB kit uses four 64GB 2Rx4 Registered ECC DDR5 modules at 1.1V CL40. This matches the board's population rules for full-capacity operation in all slots.

What does the DDR5 4800 PC5-38400 rating deliver inside the H13SVW-NT-OS1?

The modules run at 4800 MT/s with CL40 latency at 1.1V. The registered design lets the memory controller drive all four slots at this rated speed without signal degradation.

How does the 288-pin RDIMM interface and registered ECC design cap performance in practice?

The 288-pin RDIMM form factor is required by this motherboard. Registered buffering and ECC allow stable full-population operation at 4800 MT/s while correcting single-bit errors.
