Precise DDR5 ECC UDIMM upgrade

This 48GB DDR5 module runs at 5600MHz with CL46 latency and 1.1V operation. It uses a 2Rx8 unbuffered ECC design on a 288-pin form factor. The memory is built for the Supermicro H14SRV-HLN4F motherboard and installs as a direct replacement.

Matching rank and voltage for full recognition

The single specification that decides fit is the 2Rx8 rank combined with 1.1V unbuffered ECC signalling. Your board's memory controller expects this exact organisation and voltage to initialise at the rated 5600MHz speed. A different rank structure or voltage would prevent the system from recognising the full capacity or running at the specified frequency.

Sustained error correction under load

During continuous operation the on-die ECC logic detects and corrects single-bit errors in real time without halting the memory controller. The unbuffered design keeps latency low at CL46 while the 1.1V supply maintains stable signalling across extended workloads. This prevents silent data corruption and unplanned reboots that can appear after hours of computation.

Questions about this item

Will the CL46 latency on this 5600MHz DDR5 ECC module slow down my Supermicro H14SRV-HLN4F compared to lower-CL memory?

CL46 is the rated timing for DDR5-5600 ECC UDIMM. The memory controller on the Supermicro H14SRV-HLN4F is designed for this latency, so the module runs at its full 5600MHz speed without timing-related downclocking.

What does the PC5-44800 designation mean for actual bandwidth on this 2Rx8 ECC UDIMM?

PC5-44800 is the JEDEC peak transfer rate label for DDR5-5600. In this dual-rank 2Rx8 configuration, the module provides the standard DDR5-5600 bandwidth ceiling for the Supermicro H14SRV-HLN4F memory controller.

Does this 288-pin DDR5 ECC UDIMM fit the Supermicro H14SRV-HLN4F without any adapter or special mounting?

Yes. It is a standard 288-pin DDR5 UDIMM with ECC. The Supermicro H14SRV-HLN4F uses the same 288-pin UDIMM slots, so the module seats directly without adapters or brackets.
