Supermicro H13DSH upgrade kit

This 192GB kit contains twelve 16GB DDR5 6400 RDIMMs built to the exact rank, voltage and timing the Supermicro H13DSH memory controller expects. It installs as a matched set so the server recognises the full capacity at rated speed.

Registered ECC RDIMM form factor

The 288-pin registered modules offload the memory controller, allowing every slot to run fully populated at 1.1V. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

192GB headroom for dense workloads

Twelve 1Rx8 modules at CL52 deliver maximum supported capacity for virtualisation, database and compute tasks that scale with memory. Systems needing more than 192GB or a different DIMM population order must consult the motherboard manual before purchase.

Questions about this item

What is the CAS latency of the DDR5 6400 RDIMMs in this 192GB kit?

The modules run at CL52, the rated latency for the DDR5 6400 speed grade.

How much heat do the modules produce without a heat spreader during all-day operation?

They operate at 1.10 V with no heat spreader; registered buffering reduces electrical load on the memory controller, helping thermals in a fully populated server chassis.

Which motherboard must I already own for this 12-module kit to be recognized at full capacity?

The kit is validated for the Supermicro H13DSH motherboard, which requires 288-pin registered ECC RDIMMs populated per the board's memory-population rules.
