128GB DDR5-4800 ECC RDIMM kit for Supermicro

This 128GB kit contains four 32GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SVW-N memory controller expects. It is intended for administrators upgrading that specific server platform with validated, full-capacity memory.

How it fits a server build

Each module is a 288-pin RDIMM operating at 1.10V with CL40 latency and 2Rx8 organisation, matching the board's registered-DIMM requirement and population rules. The registered architecture offloads the memory controller so all four slots can run fully populated at rated speed, while on-die ECC corrects single-bit errors before they affect production workloads.

What the bundle changes

The kit ships as a matched set of four modules, eliminating the risk of mixing incompatible ranks or timings that can prevent the system from recognising the full 128GB capacity. No heat spreaders are included, so airflow in the server chassis must be sufficient for bare modules. Lifetime replacement coverage and US-based technical support are provided by the manufacturer.

Questions about this item

How much power does the 4800 MHz DDR5 kit draw at its rated 1.1 V?

The kit runs at 1.1 V; each module is a 32 GB 2Rx8 registered DIMM, so total capacity is 128 GB across four DIMMs.

Will the registered ECC modules add noticeable heat or fan noise in a fully populated Supermicro H13SVW-N?

Registered buffering reduces electrical load on the memory controller, and the modules have no heat spreader, so they rely on standard server airflow for cooling.

What motherboard slot type and population rule does the Supermicro H13SVW-N require for this 288-pin RDIMM kit?

The board needs 288-pin DDR5 RDIMM slots; the kit provides four 32 GB modules to fill the supported channels per the manual.
