32 GB DDR5-4800 ECC RDIMM for Supermicro H14DST-F

This 32 GB DDR5-4800 registered ECC module is built to the exact rank, voltage and timing the Supermicro H14DST-F memory controller expects. The 2Rx8 organisation and 1.1 V operation let the board recognise full capacity and run at the rated PC5-38400 speed without manual tuning. It is intended for administrators upgrading or populating that specific server platform.

Sustained-load behaviour

Registered buffering offloads the memory controller so every slot remains stable when fully populated under continuous workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running compute or database tasks. The CL40 latency and 1.1 V supply are maintained at the rated 4800 MT/s across extended duty cycles.

Verify DIMM population rules before ordering

Server memory support varies by model, so consult the system or motherboard manual for approved capacities, population order and installation steps. The board requires 288-pin RDIMM form factor; UDIMM or SODIMM modules will not fit or function. Confirm the maximum supported capacity per slot and the correct slot-filling sequence for your configuration.

Questions about this item

How much power does this 32GB DDR5-4800 RDIMM draw at 1.1V when running continuously?

The module operates at 1.1V; power draw scales with capacity and data rate, so a 32GB stick at DDR5-4800 typically consumes a few watts under sustained load.

Does my Supermicro H14DST-F motherboard need a specific BIOS version or CPU to support this 2Rx8 registered ECC DIMM?

The DIMM is spec-matched for the H14DST-F; consult your motherboard manual for supported capacities, approved population order, and any required BIOS updates before installation.

Can I mix this 2Rx8 CL40 registered ECC module with different-rank or different-latency RDIMMs already installed in the server?

Registered ECC architecture allows full-slot population, but mixing ranks or timings can force the controller to downclock; follow the H14DST-F population rules for stable operation.
