Exact-match DDR5 upgrade for Supermicro

This 16GB DDR5-4800 (PC5-38400) registered ECC RDIMM is built to the precise rank, voltage and timing the Supermicro H13DSG-O-CPU-D motherboard expects. The 1Rx8 organization, 1.1V operation and CL40 latency match the board's memory controller so the module is recognised at full capacity and runs at its rated speed.

Registered ECC limits for dense server populations

Registered (buffered) architecture offloads the memory controller, allowing every slot to run fully populated at full capacity without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots that would otherwise reach production workloads.

1Rx8 rank decides slot population rules

The single-rank 1Rx8 organization determines how many modules the motherboard can accept per channel and in which order they must be installed. Consult the system or motherboard manual for supported capacities, approved DIMM population order and installation steps before purchase.

Questions about this item

Should I choose the 16 GB module or a different capacity for my Supermicro H13DSG-O-CPU-D?

The module is a single 16 GB DDR5 4800 CL40 1Rx8 ECC RDIMM; your motherboard manual lists the supported capacities and the required population order for each slot.

What does the 4800 MHz rating mean once the DIMM is installed in the server?

The memory controller will run the module at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V, delivering the rated throughput when the board is fully populated.

Is the 288-pin RDIMM interface compatible with my motherboard and what does it limit?

The 288-pin Registered RDIMM form factor matches the H13DSG-O-CPU-D slots; the registered buffer lets every slot run fully populated at full speed while ECC corrects single-bit errors.
