Exact-match DDR5-4800 ECC RDIMM

This 64GB registered DDR5 module is built to the precise rank, voltage and timing the Supermicro X14SDV-20C-SP3F memory controller expects. It installs as a 288-pin RDIMM so the board recognises the full capacity and runs at the rated 4800 MT/s speed.

Thermals power and noise

The module operates at 1.1 V without a heat spreader, relying on the server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping keep system power draw stable when all slots are populated.

What the kit changes

The package supplies a single 64GB stick verified for the target motherboard, eliminating guesswork over rank configuration and population order. ECC and registered operation work together to catch single-bit errors and prevent unplanned reboots in production workloads.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in the Supermicro X14SDV-20C-SP3F, and what step is often missed?

Power down the server, open the chassis, and insert the module into the DIMM slot specified by the motherboard manual for your CPU configuration; the step most often missed is following the exact population order so the 2Rx4 registered DIMM is recognised at full 64GB capacity.

What maintenance or replacement will this 64GB DDR5 ECC RDIMM need later?

No routine maintenance is required; if a module fails it is replaced as a unit, and ECC corrects single-bit errors on the fly to prevent silent data corruption.

What limit appears first when this 1.1V CL40 DDR5-4800 RDIMM runs sustained workloads?

The registered buffer and ECC logic keep every slot stable at the rated 4800 MT/s, so the first limit is the motherboard's maximum supported capacity and population rules, not the memory itself.
