Exact-fit DDR5 ECC RDIMM kit for Supermicro H14SHM

This 32 GB kit contains two 16 GB DDR5 4800 modules built to the exact rank, voltage and timing the H14SHM memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors on the fly. It is designed for servers that require fully populated slots at rated speed without silent data corruption.

Verify DIMM population rules

Server memory support varies by model and BIOS revision. Consult the Supermicro H14SHM documentation for approved DIMM population order, maximum capacity per slot and installation steps before ordering. The 288-pin Registered form factor is required; UDIMM or SODIMM modules will not fit or function.

Low-voltage 1.10 V operation reduces power draw

Running at 1.10 V CL40, the modules draw minimal power and generate little heat under normal server workloads. No heat spreaders are fitted, so airflow through the chassis handles cooling. Registered buffering keeps electrical loading light even with all slots populated, contributing to quiet, stable operation.

Questions about this item

Does the kit include anything besides the two 16 GB DDR5-4800 RDIMM modules?

The package contains only the two 16 GB DDR5 4800 CL40 1.1 V 288-pin ECC registered DIMMs; no heat spreaders, cables, or tools are supplied.

Why choose the 32 GB 2x16 GB CL40 kit instead of a single 32 GB module or a lower-latency kit?

The Supermicro H14SHM requires registered ECC RDIMMs in matched pairs for full-channel operation; this 2x16 GB CL40 kit meets the board's rank, voltage, and timing requirements for stable population.

What does the DDR5-4800 CL40 rating deliver when installed in the H14SHM?

The modules run at 4800 MT/s with 40-cycle CAS latency at 1.1 V, providing registered ECC bandwidth and error correction exactly as the motherboard's memory controller expects.
