Server DDR5 ECC RDIMM Kit

This 32 GB kit contains two 16 GB DDR5 4800 registered ECC modules built for Supermicro IoT SuperServer systems. It targets administrators who need validated, error-correcting memory for always-on workloads.

DDR5 4800 registered limits

The DDR5 4800 interface runs at 1.1 V with CL40 latency and a single 1Rx8 rank per module. Registered buffering adds one clock cycle of command delay, which caps maximum throughput on boards that cannot drive higher speeds.

No spreader 288-pin build

Bare green PCBs without heat spreaders keep the modules low-profile for dense 288-pin slots. The 1.1 V operation reduces thermal load, so passive airflow in a 1U chassis is usually sufficient for stable daily operation.

Questions about this item

Should I choose the 2x16GB kit or a single 32GB module?

This kit provides 32GB as two 16GB modules, enabling dual-channel operation on supported Supermicro platforms for maximum bandwidth.

What does the 4800 MT/s rating deliver in a Supermicro server?

The DDR5 4800 modules run at 4800 MT/s (PC5-38400) with CL40 latency, providing the rated throughput when installed in compatible Supermicro systems.

How does the ECC RDIMM interface affect compatibility and capacity limits?

These 288-pin DDR5 ECC Registered DIMMs require a motherboard with RDIMM support; the 1Rx8 organisation allows dense population within the platform's memory-channel limits.
