NEMIX RAM DDR5 128GB (4 x 32GB) 5600MHz CL46 2Rx8 1.1V ECC Registered RDIMM Supermicro H14DSH memory upgrade

Exact-match DDR5-5600 kit for Supermicro H14DSH

This 128GB kit contains four 32GB Registered ECC RDIMMs built to the DDR5-5600 (PC5-44800) standard with CL46 timing and 1.1V operation. It targets administrators upgrading a Supermicro H14DSH motherboard where the memory controller expects this precise rank, voltage and latency combination. The 288-pin RDIMM form factor matches the board's populated slots without requiring UDIMM or SODIMM alternatives.

Sustained-load behaviour

Registered buffering offloads the memory controller so every slot runs fully populated at the rated 5600MHz speed under continuous server workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during extended production runs. The 2Rx8 organisation and 1.10V level remain stable across all four modules without throttling.

Build quality and daily mounting implications

Modules ship without heat spreaders, relying on the server chassis airflow for thermal management. The 288-pin RDIMM keying ensures correct orientation in each Supermicro H14DSH DIMM slot, while the registered design supports the board's population rules for full-capacity recognition. Verify the motherboard manual for approved DIMM order before installation.
