32 GB DDR5 RDIMM for Supermicro H13DSH

This 32 GB DDR5 4800 CL40 module is a registered ECC RDIMM built to the exact rank, voltage and timing the Supermicro H13DSH motherboard expects. It installs as a 288-pin DIMM so the server recognises the full capacity and runs at the rated 4800 MT/s speed.

Registered ECC architecture for full population

The registered buffer offloads the memory controller, allowing every slot to be populated at full capacity while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots in production workloads.

DDR5 4800 interface and population rules

The module operates at the DDR5 4800 standard with 1.1 V CL40 timing and must follow the board-specific DIMM population order and capacity limits defined in the system manual; exceeding those limits or mixing incompatible ranks will prevent the server from booting.

Questions about this item

Will the registered ECC RDIMM require any firmware updates or reconfiguration after installation?

The module is an exact-match upgrade specified at DDR5-4800 CL40 1.10 V so the server's memory controller recognises it at full capacity and rated speed without extra steps.

What limits sustained throughput when the Supermicro H13DSH runs fully populated with these 2Rx8 modules?

The DDR5-4800 CL40 timing and 1.10 V registered architecture set the bandwidth ceiling; the board's memory population rules determine how many slots can run at that speed.

How much extra heat does a 32 GB DDR5 4800 CL40 1.10 V registered module add when the system runs continuously?

Registered buffering reduces electrical load on the controller and the 1.10 V operation keeps power draw low; the module has no heat spreader so airflow through the chassis handles the thermal load.
