64GB DDR5 ECC RDIMM for SuperMicro servers

This registered DDR5 module delivers 64GB of error-correcting memory at 4800MHz with a CL40 latency. It operates at 1.1V using a 2Rx4 organisation and fits 288-pin RDIMM slots. The stick is validated for SuperMicro X13SEW-TF and X13SEW-F motherboards.

Upgrade from non-ECC or lower-capacity DDR5

Replacing standard unbuffered memory with this registered ECC DIMM adds data-integrity protection for workloads that cannot tolerate silent corruption. The jump is worth it when your platform requires registered signalling and you need the maximum single-module density this board supports.

Handles large virtualisation hosts

The 64GB capacity provides ample headroom for running multiple virtual machines or caching sizable datasets in memory. It runs out when an application demands more than 64GB per module or requires speeds beyond the 4800MHz JEDEC baseline.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the SuperMicro X13SEW-TF motherboard?

Yes, the module is a 288-pin DDR5 RDIMM built for SuperMicro X13SEW-TF and X13SEW-F boards.

What is the correct slot order when installing a single 64GB stick?

Populate the first CPU channel slot indicated in the SuperMicro manual; skipping that slot is the common error.

When should the ECC RDIMM be replaced?

Replace it if memory diagnostics report uncorrectable ECC errors or the system logs repeated corrected errors.
