Exact-Match Server Upgrade

This 512 GB kit delivers sixteen 32 GB DDR5 Registered ECC RDIMMs tuned to 4800 MT/s, CL40, at 1.1 V. It is built for administrators expanding a Supermicro H13DSG-O-CPU platform that requires the precise rank, voltage and timing the board's memory controller expects.

Registered ECC Stability

Registered buffering offloads the memory controller so every slot can run fully populated at rated speed while ECC corrects single-bit errors on the fly. The 2Rx8 organisation matches the motherboard's population rules, preventing silent data corruption and unplanned reboots in production workloads.

288-Pin RDIMM Form Factor

Modules use the standard 288-pin DDR5 RDIMM connector with no heat spreader, fitting the board's DIMM slots directly. Builders must consult the system manual for supported capacities and approved population order before installation to ensure full recognition and operation.

Questions about this item

Will the 16 32GB RDIMMs in this kit need replacement under normal server operation?

Registered ECC DDR5 modules have no moving parts and are rated for continuous operation; replacement is only needed if a module fails or capacity requirements change.

What limit appears first when all 16 slots run at DDR5 4800 continuously?

The memory controller on the Supermicro H13DSG-O-CPU defines the maximum supported capacity and population rules; the kit matches the board's 2Rx8 registered specification for full-speed operation.

How much heat and power do the 512GB of DDR5 4800 RDIMMs produce at 1.1V all day?

Each 32GB 2Rx8 module runs at 1.1V without a heat spreader; total power draw scales with the 16-module population and the server's airflow handles the thermal load.
