48GB DDR5 ECC RDIMM for Supermicro H13SSH

This 48GB DDR5 4800 Registered ECC module is built for the Supermicro H13SSH motherboard. It uses the 288-pin RDIMM form factor and 2Rx8 organisation that the board's memory controller expects. The exact voltage, rank structure and timing let the system recognise full capacity at rated speed without manual tuning. It is not for platforms that require unbuffered UDIMMs or SODIMM modules.

Thermals and power draw

Operating at 1.10V standard DDR5 voltage, the module draws minimal power per slot and runs without a heat spreader. Registered buffering reduces electrical load on the memory controller, helping stability when every slot is populated. No active cooling is required under normal server airflow. Fan noise and thermal output remain dictated by the chassis design, not the memory itself.

Registered ECC with 2Rx8 organisation

The single specification that decides fitment is the Registered ECC 2Rx8 architecture at CL40. This combination matches the H13SSH memory population rules so the board can run fully populated at 4800 MT/s. Boards that only accept unbuffered non-ECC UDIMMs or different rank configurations will not support this module. Verify your manual for approved DIMM order and maximum capacity per slot before purchase.

Questions sur cet article

How do I install the 288-pin RDIMM in the Supermicro H13SSH, and what step is often missed?

Power down and unplug the server, open the chassis, locate the DDR5 slots, and align the module's key notch with the slot before pressing firmly until both retention clips click; the step often missed is checking the motherboard manual for the exact DIMM population order required for 2Rx8 registered modules.

What maintenance or replacement will this 48GB DDR5-4800 ECC RDIMM need over time?

No routine maintenance is required for the module itself; keep the server's air filters clean and fans functional so the 1.10V DRAM stays within thermal limits, and replace the unit only if ECC logs report uncorrectable errors or the system fails to train at 4800 MT/s.

What limit appears first when this 2Rx8 CL40 registered memory runs sustained workloads?

The registered buffer and ECC logic add latency, so the CL40 timing at 4800 MT/s becomes the bottleneck before bandwidth saturates, especially with all channels fully populated on the H13SSH.
