48GB DDR5 ECC RDIMM for Supermicro H14SHM

This 48GB DDR5-4800 Registered ECC module is built as an exact-match upgrade for the Supermicro H14SHM motherboard. It delivers the precise 2Rx8 rank structure, 1.1V operating voltage and CL40 timing the board's memory controller expects. System administrators expanding server memory capacity will find it recognised at full rated speed without manual tuning.

288-pin Registered form factor with ECC

The module uses a 288-pin RDIMM design, not a UDIMM or SODIMM, so it seats only in slots wired for Registered memory. Its buffered architecture reduces electrical load on the controller, allowing full population of every supported slot while ECC corrects single-bit errors in real time. No heat spreader is fitted, so airflow across the DIMM rows must be maintained by the chassis fans.

Check motherboard manual for population rules

Supported capacities, approved DIMM population order and installation steps vary by server configuration, so consult the Supermicro H14SHM manual before ordering. The module operates at 1.1V DDR5 standard voltage; systems requiring a different voltage will not be compatible. Buyers needing unbuffered UDIMMs or non-ECC memory for workstation boards should look elsewhere.

Questions about this item

What DDR5 speed and CAS latency does this 48GB RDIMM run at?

The module operates at DDR5 4800 (PC5-38400) with a CAS latency of CL40.

What physical slot and form factor does this 288-pin RDIMM require?

It fits a standard 288-pin DDR5 RDIMM slot on the Supermicro H14SHM motherboard; it is not a UDIMM or SODIMM.

How do I install this registered ECC module and what population rule do people miss?

Power down, open the chassis, align the notch with the DDR5 RDIMM slot, press firmly until the latches click, then consult the H14SHM manual for the exact DIMM population order required when filling multiple slots.
