NEMIX RAM 2TB DDR5 4800 Server Kit

This NEMIX RAM kit delivers 2TB of DDR5 4800 memory in sixteen 128GB registered DIMMs. It is built for THINKMATE Supermicro SuperServer 681E-TR systems that require ECC RDIMM modules. The modules operate at 1.1V with a CAS latency of CL40 and use a 4Rx4 organisation. They are designed for enterprise workloads that demand high capacity and error correction.

Suited for 681E-TR upgrades.

IT teams upgrading compatible THINKMATE servers will find the registered ECC design matches the platform requirements. The 288-pin DDR5 form factor fits the target motherboard slots. Builders using consumer motherboards or workstations that only accept unbuffered UDIMMs cannot use this kit. Systems limited to lower maximum module densities or different pin counts should look elsewhere.

2TB total capacity across sixteen DIMMs

The decisive specification is the 2TB total capacity provided by sixteen 128GB modules. This density determines whether the server can reach its memory ceiling and support the intended virtualisation or database workloads. Verify the motherboard supports 16 DIMM slots and 128GB per slot before purchasing.

Questions about this item

Does this kit fit the 288-pin DDR5 RDIMM slots in a ThinkMate Supermicro SuperServer 681E-TR?

Yes — the kit provides 16 modules of 128 GB each, built as 288-pin DDR5 RDIMMs that match the server's registered DIMM sockets.

What is the correct order for populating the 16 DIMM slots during installation?

Follow the motherboard manual's population sequence for 4Rx4 registered modules; a common mistake is filling slots sequentially instead of the prescribed interleaved pattern.

When should a module from this 16-piece kit be swapped out?

Replace any module that reports uncorrectable ECC errors or fails a full memory diagnostic; otherwise the registered DDR5 DIMMs require no scheduled maintenance.
