Exact-match DDR5 RDIMM for Supermicro H14SHM

This 16GB DDR5-4800 module delivers PC5-38400 bandwidth at 1.1V with CL40 latency. Registered ECC architecture with 1Rx8 organisation is the precise configuration the H14SHM memory controller expects for full-capacity recognition. The 288-pin RDIMM form factor matches the board's physical slots exactly.

Straightforward slot installation

Align the notch on the 288-pin module with the keyed socket and press evenly until the retention clips engage. Registered ECC RDIMMs must follow the motherboard's approved population order, so consult the H14SHM manual for the correct slot sequence before adding or mixing modules. No heat spreader is present, leaving clearance for standard server airflow paths.

Sustained enterprise stability under full load

Registered buffering reduces electrical load on the memory controller, allowing every populated slot to run at the rated 4800 speed continuously. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption during long-running workloads. The 1.1V operating voltage keeps power draw consistent across extended duty cycles.

Questions about this item

How do I verify the module is running at 4800 MT/s with CL40 timing after installation?

Enter the server BIOS and confirm the memory speed shows 4800 MT/s and CAS latency 40; the registered ECC design lets the controller initialise at the rated frequency when population rules are followed.

What comes in the package and do I need any extra parts for the Supermicro H14SHM?

The box contains one 16 GB 288-pin DDR5 RDIMM; no additional components are required for a slot that accepts registered ECC memory.

Which capacity should I choose if my board supports 16 GB per slot?

Select the 16 GB module to match the per-slot limit and populate slots in the order specified by the motherboard manual.
