16GB DDR5 4800 ECC RDIMM for SuperMicro X13SEI-F/TF

This 16GB DDR5 4800 ECC RDIMM module is built for SuperMicro X13SEI-F and X13SEI-TF server motherboards. It provides registered error-correcting memory for workloads that require data integrity and system stability. The single-rank 1Rx8 design operates at 1.1V with CL40 latency. It suits administrators expanding memory in compatible SuperMicro platforms.

Upgrading from non-ECC or lower-capacity DDR5

The jump is worth it when your current configuration lacks error correction or cannot address the dataset size needed for virtualization, databases, or file services. Registered DDR5 reduces electrical load on the memory controller, allowing larger total capacities than unbuffered alternatives. If your existing modules are unbuffered, non-ECC, or simply too few, this kit adds both capacity and reliability in one step.

Verify motherboard model, slot population rules.

Confirm the board is exactly a SuperMicro X13SEI-F or X13SEI-TF before ordering; other X13 or SuperMicro models are not guaranteed compatible by this listing. Check the manual for supported DIMM population sequences and maximum per-channel ranks. Ensure the platform accepts 1.1V DDR5 RDIMM modules and that open 288-pin slots are available for the 1Rx8 configuration.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the DIMM slots on my SuperMicro X13SEI-F or X13SEI-TF motherboard?

Yes, the module uses the standard 288-pin DDR5 RDIMM form factor designed for the DIMM slots on those SuperMicro motherboards.

What is the correct way to seat this registered ECC module, and what step do builders often miss?

Align the notch on the module with the key in the slot, press down firmly until both side clips click shut, and verify the system detects the full 16 GB at 4800 MT/s in BIOS.

When should I expect to replace this 1Rx8 DDR5 4800 CL40 module in a server workload?

DDR5 RDIMMs have no scheduled replacement interval; they remain in service until a capacity upgrade is needed or a module fails validation testing.
