SuperMicro DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit supplies 64 GB of DDR5 4800 registered ECC memory in two 32 GB modules. It is built for SuperMicro IoT SuperServer SYS-211SE-31D, SYS-211SE-31A and X31SEED-F platforms. The modules run at 1.1 V with CL40 latency and use a 288-pin RDIMM form factor.

IT teams upgrading validated SuperMicro servers

Administrators who need guaranteed compatibility with the listed SuperMicro systems will find this kit tested for those platforms. Builders using other motherboards, desktop chipsets or non-ECC memory controllers should look elsewhere because the modules are registered ECC RDIMMs that require server-class memory support.

Two-rank 1Rx4 layout at 4800 MT/s

The 64 GB capacity handles virtualization hosts, database buffers and large file caches in the target SuperMicro systems. Workloads that demand higher bandwidth than PC5-38400 or capacities beyond 64 GB per kit will exceed what this specific configuration provides.

Questions about this item

My SuperMicro SYS-211SE-31D has empty 288-pin DDR5 slots — will this 2×32 GB kit fill them correctly?

Yes. The kit contains two 32 GB 288-pin DDR5 RDIMMs, matching the slot count and pin layout of the SYS-211SE-31D.

Can I keep my existing DDR5 4800 CL40 registered ECC modules and add this kit to the same server?

Yes, provided the installed modules are also 1.1 V DDR5 4800 CL40 1Rx4 registered ECC RDIMMs; mixing different speeds, ranks or voltages may prevent the system from posting.

After seating both modules, how can I confirm the server sees the full 64 GB at 4800 MT/s with ECC active?

Enter the BIOS or use a hardware-inventory tool such as dmidecode; it should report 64 GB total, DDR5 4800, CL40, registered ECC and 1.1 V operation.
