Server-grade DDR5 capacity

This NEMIX RAM kit delivers 256GB across two 128GB DDR5 5600 RDIMM modules built for Supermicro X13SEI-F and X13SEI-TF platforms. Registered ECC operation at 1.1V with CL46 timing provides error-corrected throughput for memory-intensive workloads. The 4Rx4 organisation and 288-pin form factor match the motherboard's registered DIMM slots directly.

Suited for registered ECC platforms

This memory fits administrators expanding Supermicro servers that require registered ECC RDIMMs at DDR5 5600 speeds. Systems needing unbuffered DIMMs, non-ECC operation, lower capacities or different pin layouts cannot use this kit. Buyers without compatible registered DDR5 motherboards should look at other memory types.

Kit simplifies matched-pair deployment

The two-module package eliminates manual pairing and ensures identical rank, voltage and timing characteristics across both slots. Samsung, Micron or Hynix major-OEM chips are stress-tested under load before shipping. No heat spreaders are included, so airflow management follows the chassis design.

Questions about this item

What motherboard must I already own for this 256GB DDR5 5600 4Rx4 ECC RDIMM kit to work?

The kit is validated for the SuperMicro X13SEI-F and X13SEI-TF motherboards.

How will these 5600MHz CL46 registered modules behave alongside slower DDR5 DIMMs I may keep installed?

The motherboard will clock all installed DDR5 memory down to the speed of the slowest module.

How can I confirm the 2x128GB 4Rx4 kit is running at 5600MHz with ECC active after installation?

Check the BIOS memory information screen for 5600MT/s, CL46 timings and ECC status enabled.
