Exact-match DDR5 ECC RDIMM kit for Supermicro H13SRH

This 192GB kit contains four 48GB DDR5 4800 modules built to the 2Rx8 Registered ECC specification at 1.1V CL40. It is intended for administrators who need the precise rank, voltage and timing that the H13SRH memory controller expects so the server recognises full capacity at rated speed.

Registered ECC architecture for fully populated

Registered buffering offloads the memory controller allowing every slot to run fully populated at full capacity while ECC catches and corrects single-bit errors on the fly. This combination stops silent data corruption and unplanned reboots before they reach production workloads.

Verify DIMM population rules in your manual

Server and motherboard memory support varies by model so consult your system or motherboard manual for supported capacities approved DIMM population order and installation steps before purchase. This kit uses the 288-pin RDIMM form factor required by the board not UDIMM or SODIMM.

Questions about this item

Will the 48GB RDIMMs need any firmware updates or periodic reseating to stay stable in the Supermicro H13SRH?

The modules are an exact-match DDR5-4800 kit validated for that motherboard; no firmware updates or reseating schedule are required once they are seated correctly.

What limit appears first when the 192GB kit runs at full DDR5-4800 CL40 1.1V load for hours?

The memory controller on the H13SRH reaches its maximum supported bandwidth before the RDIMMs hit any thermal or voltage ceiling.

How much heat does the 4x48GB kit produce at 1.1V during continuous operation?

Registered DDR5 at 1.1V draws modest power per module, so the kit adds only a small amount of heat to the server's existing airflow.
