1 TB DDR5 ECC RDIMM kit for Thinkmate servers

This NEMIX RAM kit delivers 1 TB of DDR5 4800 memory using eight 128 GB registered ECC RDIMMs. Each module runs at 1.1 V with CL40 latency and a 4Rx4 organisation across 288 pins. The set is validated for Thinkmate Supermicro SuperServer 111C-NR, 121C-TN2R and 121C-TN10R platforms.

Suited for memory-heavy server workloads.

Administrators expanding virtualisation hosts, in-memory databases or HPC clusters on the listed Thinkmate systems will benefit from the capacity and error correction. Builds that need unbuffered DIMMs, lower-density modules or non-ECC memory should look elsewhere.

Registered ECC RDIMM form factor decides

The modules are 288-pin DDR5 RDIMMs with on-board register and ECC, so they only fit motherboards wired for registered ECC DDR5. Consumer boards and workstations that require UDIMMs cannot use this kit.

Questions about this item

How do I install the 8x128GB DDR5 4800 RDIMMs in the Supermicro 111C-NR, and which step is often missed?

Power down, open the chassis, align each 288-pin module with the slot key, press firmly until both latches click, then verify all eight show in BIOS; the step most often missed is seating every module fully so both latches engage.

What maintenance or replacement will this 1TB DDR5 ECC RDIMM kit need later?

No scheduled maintenance is required; if a module fails, replace the faulty 128GB stick with an identical DDR5 4800 CL40 4Rx4 1.1V RDIMM to keep rank and voltage consistent.

What limit appears first under sustained load with these CL40 1.1V registered modules?

The CAS latency of 40 cycles at 4800 MT/s sets the timing floor; sustained throughput is bounded by the DDR5 4800 data rate and the 4Rx4 organisation.
