Purpose-built DDR5 server module

This 48 GB DDR5 4800 RDIMM is built for the Supermicro H14DST-FL motherboard. It delivers registered ECC operation at 1.1 V with CL40 latency for workloads that demand error correction and full-slot population.

Build integration

The 288-pin registered form factor matches the board's DIMM slots and population rules, so every channel runs at rated speed when fully loaded. Registered buffering reduces electrical load on the memory controller, while on-die ECC corrects single-bit errors before they affect data integrity.

Upgrade context

It replaces lower-capacity or non-ECC DDR5 modules when the platform requires registered memory and maximum slot utilisation. The jump is worthwhile when your configuration calls for 48 GB per DIMM at the native 4800 MT/s data rate with verified compatibility.

Questions about this item

Will the 4800 MT/s speed and CL40 latency hold steady under sustained server workloads?

The module runs at DDR5 4800 with CL40 timings at 1.1 V; registered buffering keeps the memory-controller load low so rated speed is maintained when all slots are populated.

How much heat and power should I expect from this 48 GB RDIMM in a fully populated Supermicro H14DST-FL running continuously?

Operating at 1.1 V without a heat spreader, the registered ECC design minimises electrical load on the controller, keeping thermals and power draw low during extended operation.

Does my Supermicro H14DST-FL need a specific BIOS version or CPU stepping to recognise this 2Rx8 registered ECC module?

The DIMM is validated for the Supermicro H14DST-FL motherboard; consult your system manual for approved population order and any firmware requirements before installation.
