48GB DDR5 RDIMM for Supermicro H13SSW

This 48GB DDR5 4800 PC5-38400 module is a registered ECC RDIMM built for the Supermicro H13SSW motherboard. It operates at 1.1V with CL40 latency and a 2Rx8 rank structure. The 288-pin form factor matches the board's DIMM slots exactly. System administrators upgrading compatible Supermicro servers use this memory to expand capacity with assured fitment.

Suits servers needing registered ECC at 4800 MT/s

This module suits environments that require registered ECC DDR5 at the native 4800 speed with 1.1V operation. It is not for systems that accept only unbuffered UDIMMs or SODIMM form factors. Builders needing speeds above 4800 or lower CAS latencies should look elsewhere. Workstations without ECC support in the memory controller will not benefit from the error-correction feature.

2Rx8 rank and 1.1V define compatibility

The single specification that decides fitment is the 2Rx8 registered rank combined with 1.1V DDR5 signalling. The Supermicro H13SSW memory controller expects this exact rank structure and voltage to initialise the DIMM at full capacity and rated speed. A different rank count or voltage will prevent the server from posting or force reduced performance. Verify the motherboard manual for approved population rules before installation.

Questions sur cet article

Will the 2Rx8 registered DIMM need any firmware updates or module replacements during its service life?

Registered ECC RDIMMs like this 48 GB DDR5 4800 module are solid-state with no moving parts or firmware; they run until a rare cell failure triggers ECC correction, at which point the module is simply replaced.

What limit appears first when the Supermicro H13SSW runs this 1.1 V DDR5 kit at full load continuously?

The memory controller’s thermal and power envelope is reached before the DIMM’s own 1.10 V rating, so sustained throughput is capped by the platform’s cooling and population rules rather than the module itself.

How much noise and heat does this 288-pin RDIMM add when the server runs all day?

The module has no heat spreader or fan; it draws 1.1 V at DDR5 4800 and relies on the chassis airflow, so it contributes negligible acoustic noise and only modest heat to the system’s overall thermal load.
