256GB DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 256GB of DDR5 memory across sixteen 16GB registered DIMMs. It is built for SuperMicro X13SET-G and X13SET-GC motherboards that require ECC RDIMM modules. The memory runs at 4800MT/s with a CAS latency of 40 and operates at 1.1V.

Suited for server administrators expanding capacity

The kit targets IT professionals who need to maximise memory on the named SuperMicro platforms for virtualisation, databases or other memory-intensive workloads. It is not for desktop PCs, laptops or workstations that use unbuffered non-ECC DDR5. Buyers who need a different capacity, speed or form factor should look at other memory kits.

Verify motherboard model and slot count

Confirm the motherboard is exactly a SuperMicro X13SET-G or X13SET-GC before ordering. Ensure the board has sixteen available 288-pin DDR5 RDIMM slots to accept the full kit. Check the system documentation for any population rules or maximum supported capacity per channel.

Questions about this item

Does my SuperMicro X13SET-G or X13SET-GC motherboard need all 16 DDR5 slots populated to use this 256 GB kit?

The kit contains 16 modules of 16 GB each, so every DDR5 RDIMM slot on the board must be filled to install the full 256 GB capacity.

Can I mix these registered ECC RDIMMs with unbuffered memory already installed in the system?

No, registered ECC RDIMMs and unbuffered modules use different signalling and cannot be combined on the same motherboard.

How do I verify the memory is running at DDR5 4800 with CL40 timings after installation?

Check the BIOS memory information screen or use a tool such as CPU-Z to confirm the speed reads 4800 MT/s and the CAS latency shows 40.
