Exact-match DDR5-6400 RDIMM kit

This 64GB kit contains two 32GB DDR5-6400 RDIMMs built for the Supermicro H13SVW-NT motherboard. Each module runs at 1.1V with CL52 latency and uses a 2Rx8 registered ECC design. The parts are specified to match the board's memory controller so the full capacity is recognised at rated speed.

Registered ECC population limits

Registered DIMMs offload the memory controller to allow every slot to run fully populated, while ECC corrects single-bit errors on the fly. The motherboard manual defines the supported capacities and the required DIMM population order for this platform. Installing modules outside that sequence can prevent the system from posting or force a lower speed.

2Rx8 registered ECC at 1.1V

The dual-rank registered ECC organisation at 1.1V is the single specification that determines whether this kit works in the target server. A mismatch in rank, voltage, or buffering type will cause the memory controller to reject the modules or fall back to a reduced configuration.

Questions about this item

Should I choose the 2×32 GB kit or a different capacity for my Supermicro H13SVW-NT?

The 64 GB (2×32 GB) kit matches the board's 288-pin RDIMM slots and population rules; other capacities would need separate verification against the motherboard manual.

What does the DDR5-6400 (PC5-51200) rating deliver once installed?

The modules run at 6400 MT/s with CL52 latency at 1.10 V, providing the exact bandwidth and timing the server's memory controller expects for full-speed operation.

How does the 288-pin ECC Registered DDR5 interface affect real-world limits?

The registered design buffers each command so all slots can be fully populated at 6400 MT/s, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
