Exact DDR5-4800 RDIMM for Supermicro H14DST-F

This 16 GB registered ECC module matches the DDR5-4800 (PC5-38400) speed, 1.1 V voltage, CL40 timing and 1Rx8 rank that the Supermicro H14DST-F motherboard expects. It installs as a direct upgrade so the server recognises full capacity and runs at rated speed without manual tuning.

Registered ECC build with 288-pin form factor

The registered architecture buffers address and command signals, allowing every slot to be populated at full capacity while ECC corrects single-bit errors before they cause silent data corruption or unplanned reboots. No heat spreader is fitted, so airflow in dense server chassis passes freely over the DRAM chips.

Verify DIMM population rules before ordering

Server and motherboard memory support varies by model, so consult the system or motherboard manual for approved capacities, slot population order and installation steps. Buyers who need a different capacity, a non-ECC module or a UDIMM form factor should look elsewhere because this kit is a single 16 GB registered ECC RDIMM only.

Questions about this item

Does the DDR5 4800 interface on this module cap at PC5-38400 bandwidth?

Yes, the DDR5 4800 (PC5-38400) interface runs at its rated 4800 MT/s, delivering up to 38400 MB/s peak bandwidth per module.

What physical slot and form factor does this 288-pin RDIMM require on the Supermicro H14DST-F?

It fits a standard DDR5 288-pin RDIMM slot; the registered form factor is keyed for server motherboards and will not fit UDIMM or SODIMM sockets.

What is the correct installation step for this 1Rx8 registered ECC module that people often miss?

Follow the H14DST-F manual's DIMM population order exactly — registered modules must populate specific slots first for the memory controller to initialise all ranks at 4800 MT/s.
