Server Memory Kit

This 768 GB DDR5 RDIMM kit supplies 16 modules of 48 GB each, running at 4800 MT/s with CL40 latency and 1.1 V operation. Registered ECC architecture and 2Rx8 organisation let the memory controller manage full population across all slots. It is built for Supermicro H13DSG-OM motherboards that require 288-pin registered DIMMs.

Fitment Guidance

The kit matches the H13DSG-OM motherboard's registered DIMM requirement and population rules, so administrators upgrading that platform can fill every slot at rated speed. Builders using consumer boards, workstations that accept only unbuffered UDIMMs, or systems limited to lower maximum capacities should choose a different memory type.

Registered ECC RDIMM

Registered buffering offloads the memory controller, allowing all 16 slots to run at 4800 MT/s without signal degradation, while ECC corrects single-bit errors in flight. This combination is the single specification that determines whether the module will be recognised and stable in the target Supermicro server.

Questions about this item

Will all sixteen 48 GB DDR5 4800 RDIMMs run at full speed when the server is fully loaded for hours?

The kit is spec-matched to the Supermicro H13DSG-OM motherboard population rules, so every slot runs at the rated DDR5 4800 speed with CL40 timing at 1.1 V even when all sixteen modules are populated.

How much heat and power should I expect from a fully populated 768 GB DDR5 4800 RDIMM kit running continuously?

Each module operates at 1.1 V without a heat spreader; total power draw scales with sixteen 2Rx8 ranks, so plan for typical registered DDR5 thermals and ensure the chassis airflow matches the motherboard layout.

What motherboard and firmware must I already have for this 16 x 48 GB DDR5 4800 ECC RDIMM kit to be recognised?

The kit is verified for the Supermicro H13DSG-OM motherboard; you need that board with a BIOS version that supports 768 GB of registered ECC DDR5 4800 memory in a sixteen-DIMM configuration.
