  • Exact-match 16 GB DDR5-4800 CL40 1Rx8 ECC RDIMM for Supermicro H14DSG-OD
  • Registered architecture offloads the controller so every slot runs fully populated at rated speed
  • ECC corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots
  • 10 V operation at 4800 MHz delivers rated performance without exceeding platform limits
  • 288-pin RDIMM form factor matches the board's required slot type and population rules

Exact-Match Server Memory

This 16GB DDR5-4800 registered ECC RDIMM is built to the precise rank, voltage and timing the Supermicro H14DSG-OD motherboard expects. It installs as a single 288-pin module so the memory controller recognises full capacity at rated speed without manual tuning.

Thermals Power And Noise

Operating at 1.1V with no heat spreader, the module draws minimal power and produces no audible noise in normal server airflow. The registered architecture reduces electrical load on the memory controller, helping keep system thermals stable during typical workloads.

Sustained Load Behaviour

ECC corrects single-bit errors on the fly while the registered buffer maintains signal integrity across every populated slot. This prevents silent data corruption and unplanned reboots during extended production runs, keeping throughput consistent over time.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in the Supermicro H14DSG-OD, and which slot order do people often get wrong?

Insert the module into the 288-pin DDR5 RDIMM slots following the motherboard manual's population sequence; the common mistake is filling slots out of order, which prevents the board from recognising the full 16GB capacity at 4800MHz.

What maintenance or replacement will this 1Rx8 ECC RDIMM need over its service life?

No scheduled maintenance is required; the registered ECC design corrects single-bit errors automatically, and the module is covered by a lifetime replacement warranty if a hardware fault ever develops.

What limit appears first when this CL40 1.1V module runs under sustained load?

The CAS latency of CL40 and the fixed 1.1V operating voltage define the timing and power envelope; sustained workloads will hit these electrical limits before any thermal throttle, as the module has no heat spreader.
