  • 192 GB total capacity in a 12-module kit for maximum server memory density
  • DDR5 4800 speed with CL40 latency delivers rated throughput for the H13DSH platform
  • Registered ECC architecture offloads the controller and corrects single-bit errors for production stability
  • 1 V operation at 1Rx8 rank matches the board's exact voltage and timing requirements
  • 288-pin RDIMM form factor fits the Supermicro H13DSH memory slots without adapters

Exact-match 192 GB DDR5 ECC RDIMM kit

This 12-module kit delivers 192 GB of DDR5-4800 registered ECC memory in a 1Rx8 configuration at 1.1 V and CL40. It is built to the precise rank, voltage and timing the Supermicro H13DSH memory controller expects for full-capacity recognition at rated speed.

Registered 288-pin form factor for full population

The registered RDIMM architecture offloads the memory controller so every slot runs fully populated at full capacity. ECC corrects single-bit errors on the fly to stop silent data corruption and unplanned reboots before they reach production. Modules lack heat spreaders, so verify airflow in dense chassis.

Replaces smaller or mixed-capacity DDR5 RDIMM sets

The jump is worth it when your workload needs the full 192 GB at native DDR5-4800 without down-clocking from rank or population limits. Buyers who need a different DIMM type, lower voltage or non-ECC operation should look elsewhere.

Questions about this item

What DDR5 speed and PC5 rating does this kit run at?

The kit operates at DDR5 4800 with a PC5 38400 data rate, matching the Supermicro H13DSH memory controller specification.

What physical slot and form factor do these modules require?

Each module is a 288-pin Registered RDIMM; the motherboard must provide 288-pin DDR5 RDIMM slots, not UDIMM or SODIMM sockets.

How should the 12 modules be installed, and what step is often missed?

Follow the H13DSH manual's exact population order for 12 DIMMs; the step most often missed is seating every module until both ejector clips click, otherwise the server will not recognise the full 192GB capacity.
