Supermicro H13SRH DDR5 RDIMM Kit

This 32 GB kit contains two 16 GB DDR5 RDIMM modules built for the Supermicro H13SRH motherboard. Registered ECC design with 1Rx8 organisation and CL40 timing matches the board's memory controller requirements. Modules run at 4800 MT/s (PC5-38400) on 1.10 V without heat spreaders.

Fitment for H13SRH registered slots

Suits administrators upgrading a Supermicro H13SRH platform that requires registered ECC DDR5 RDIMMs in a 2 x 16 GB configuration. Builders needing UDIMM, SODIMM, non-ECC or higher-capacity DIMMs should look at other memory types.

DDR5 4800 CL40 1Rx8 registered spec

The single specification that decides compatibility is the DDR5 4800 CL40 1Rx8 registered RDIMM profile at 1.10 V. The Supermicro H13SRH memory controller expects this exact rank, voltage and timing combination for full-speed operation.

Questions about this item

Does the 32GB kit include both 16GB DDR5 RDIMMs or do I need to buy a second module separately?

The kit contains two 16GB DDR5 4800 CL40 1Rx8 ECC Registered RDIMMs, giving 32GB total with nothing else required.

Should I choose this CL40 1.1V 1Rx8 kit or a different speed or rank for the Supermicro H13SRH?

This exact-match kit matches the board's DDR5 4800 PC5-38400 1Rx8 Registered ECC 1.1V specification so it is recognised at full capacity and rated speed.

What does the DDR5 4800 PC5-38400 rating mean once the modules are installed in the H13SRH?

The modules run at 4800 MT/s with CL40 latency at 1.1V, delivering the bandwidth and registered ECC stability the server's memory controller expects.
