128GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit provides 128GB across four 32GB modules running at DDR5 4800 with CL40 latency. It uses registered ECC RDIMM architecture at 1.1V for server and workstation stability. The modules are validated for Thinkmate Supermicro SuperServer 111C-NR, 121C-TN2R and 121C-TN10R systems.

Suited for Thinkmate SuperServer upgrades

Administrators expanding memory in the listed Thinkmate SuperServer models will find this kit a direct match. It is not intended for consumer desktops, laptops or non-ECC platforms that cannot use registered DIMMs. Buyers needing unbuffered memory or higher speeds should look elsewhere.

Straightforward DIMM installation

The 288-pin RDIMMs seat like standard server memory; populate the correct slots per the system manual. Common issues include mixing registered and unbuffered modules or skipping the required BIOS update for full 128GB recognition. No heat spreaders are fitted, so airflow in the chassis matters.

Questions about this item

What motherboard slot type is required for these 288-pin DDR5 RDIMM modules?

The modules use the standard 288-pin DDR5 RDIMM form factor and require a server or workstation motherboard with matching DDR5 RDIMM slots.

Can these ECC registered DDR5 DIMMs run alongside non-ECC unbuffered DDR5 memory already installed?

No, ECC registered DDR5 RDIMMs cannot be mixed with non-ECC unbuffered DDR5; all slots must use the same registered ECC type for stable operation.

How can I confirm the kit is running at the rated 4800 MT/s and CL40 latency after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 4800 MT/s with CAS latency set to CL40.
