Server ECC RDIMM

This 16GB DDR5 module is built for SuperMicro IoT SuperServer SYS-211SE systems that require registered error-correcting memory. It targets administrators upgrading or populating the X31SEED-F motherboard with validated server-grade RAM.

Registered DDR5 4800 CL40

The single decisive spec is the registered DDR5 4800 speed with CL40 latency and 1.1V operation, which must match the platform's memory controller requirements. Unbuffered or non-ECC modules will not function in this server.

288-pin RDIMM form factor

The module plugs directly into a 288-pin DDR5 RDIMM slot on the X31SEED-F board and draws 1.1V from the server's power delivery. It adds 16GB of ECC capacity per slot without needing a heat spreader or extra cooling clearance.

Questions about this item

What does the 4800 MT/s rating mean once the module is installed in a SuperMicro SYS-211SE?

The module will run at up to 4800 MT/s, delivering PC5-38400 bandwidth, provided the server's memory controller and BIOS support that speed.

How does the DDR5 RDIMM interface and CL40 latency affect real-world throughput?

The registered DDR5 interface adds a clock cycle for signal buffering, and CL40 sets the minimum read latency at 40 cycles, capping random-access responsiveness at this timing.

Will the 288-pin 1Rx8 stick fit the memory slots on an X31SEED-F motherboard?

Yes, the 288-pin DDR5 RDIMM form factor matches the X31SEED-F DIMM slots, and the single-rank 1Rx8 organisation is compatible with the platform's memory topology.
